    Summary
    This report describes the exemptions from COVID-19 containment measures for fully vaccinated and recently
    recovered individuals in Bahrain, Chile, France, Germany, Israel, the United Kingdom and the United States.
    The report also briefly discusses exemptions for individuals with negative COVID-19 tests. Weekly COVID-19
    incidence has been decreasing in all countries but Bahrain. The available evidence on circulation of VOC indicates
    that the vaccines used in the seven countries are mostly effective against VOC B.1.1.7, B.1.351 and P.1. However,
    there is not sufficient evidence yet on the impact of VOC B.1.617 on vaccine effectiveness. Vaccine acceptance is
    lower in France, Israel and the United States and higher in Germany and the United Kingdom. Bahrain, Israel
    and the United States currently universally offer COVID-19 vaccinations. Chile, France, Germany and the United
    Kingdom continue to expand vaccination rollout to progressively younger population groups. Nonetheless, full
    vaccination coverage is relatively low in all seven countries. As of 9 May 2021, full vaccination was below 40% in
    Germany, France, the United Kingdom, Bahrain, the United States and Chile. Israel had fully vaccinated 58.7%
    of its population as of that date. Therefore, the vast majority of populations is currently not protected from
    COVID-19 and continues to be able to transmit the virus, if infected.
    The United States, Israel and the United Kingdom have progressively lifted containment measures. France and
    Germany continue to maintain tighter containment measures. Bahrain presents a mix of loosening and
    tightening of measures over time. Bahrain, Germany, Israel and the United States offer exemptions from COVID-
    19 containment measures to individuals with a negative COVID-19 test, those who are recently recovered or those
    who are fully vaccinated. Exemptions often regard access to leisure activities and easier international travel. Most
    of the countries offer equal exceptions to recently recovered and fully vaccinated individuals. France and the
    United Kingdom do not currently offer exemptions to COVID-19 containment measures. However, such
    exemptions are under discussion in both countries.
    Limited evidence from Germany suggests that exemptions for fully vaccinated and recently recovered individuals
    do not incentivize non-vaccinated individuals to get vaccinated as soon as possible. In light of this evidence, it is
    unclear if granting exemptions to COVID-19 containment measures may provide an incentive to currently
    unvaccinated individuals to receive the vaccine.
    Risks to COVID-19 containment posed by granting exemptions depend inter alia on the epidemiological context
    and the extent of full vaccination coverage. In Bahrain and Germany, granting exemptions in a context of higher
    incidence may potentially weaken the effect of containment measures in place. All countries granting exemptions
    should invest in sustained risk communication and community engagement to stress the continued importance
    of protective behaviors (mask-wearing, physical distancing, hand-washing, ventilation) to protect the non-
    vaccinated population.

    Zusammenfassung
    Dieser Bericht befasst sich mit der Lockerung von COVID-19-Eindämmungsmaßnahmen für vollständig
    geimpfte und genesene Personen in Bahrain, Chile, Deutschland, Frankreich, Israel, dem Vereinigten
    Königreich und den Vereinigten Staaten. Der Bericht befasst sich auch mit den Lockerungen für negativ getestete
    Personen. Die wöchentliche COVID-19-Inzidenz ist zuletzt in allen Ländern außer Bahrain gesunken. Die
    verfügbare Evidenz zeigt, dass die in den sieben Ländern verwendeten Impfstoffe wirksam gegen VOC B.1.1.7,
    B.1.351 und P.1 sind. Die Auswirkungen von VOC B.1.617 auf die Impfstoffeffektivität sind noch nicht
    ausreichend erforscht.
    Die Impfakzeptanz ist in Frankreich, Israel und den USA geringer und in Deutschland und Großbritannien
    höher. Bahrain, Israel und die USA machen derzeit ihren gesamten Bevölkerungen ein Impfangebot. Chile,
    Frankreich, Deutschland und das Vereinigte Königreich weiten ihre Impfungen auf zunehmend jüngere
    Bevölkerungsgruppen aus. Trotzdem ist die Durchimpfungsrate (2. Dosis) in allen sieben Ländern relativ gering.
    Am 9. Mai 2021 lag diese in sechs von sieben Ländern unter 40%. Israel hatte zu diesem Zeitpunkt 58,7% seiner
    Bevölkerung vollständig geimpft. Daher ist die überwiegende Mehrheit der Bevölkerungen derzeit nicht vor
    COVID-19 geschützt und kann das Virus bei einer Infektion weiterhin übertragen.
    Die Vereinigten Staaten, Israel und das Vereinigte Königreich haben ihre Eindämmungsmaßnahmen
    schrittweise gelockert. Frankreich und Deutschland halten weiterhin strengere Eindämmungsmaßnahmen
    aufrecht. In Bahrain wechseln sich inkrementelle Lockerungen und Verschärfungen über Zeit ab. Bahrain,
    Deutschland, Israel und die Vereinigten Staaten haben ihre Maßnahmen für Personen mit negativem COVID-
    19-Test, kürzlich Genesene oder vollständig Geimpfte gelockert. Die Lockerungen betreffen häufig den Zugang
    zu Freizeitaktivitäten und Erleichterungen bei internationalen Reisen. Die meisten Länder unterschieden bei
    den Lockerungen nicht zwischen kürzlich genesenen und vollständig geimpften Personen. Frankreich und das
    Vereinigte Königreich lockern derzeit nicht ihre COVID-19-Eindämmungsmaßnahmen für ausgewählte
    Personengruppen. Über derartige Ausnahmen wird jedoch aktuell in beiden Ländern beraten.
    Eine Untersuchung aus Deutschland deutet darauf hin, dass Lockerungen für vollständig geimpfte und kürzlich
    genesene Personen für nicht geimpfte Menschen keinen nennenswerten Anreiz darstellen, sich so schnell wie
    möglich impfen zu lassen. Angesichts dessen ist unklar, ob Lockerungen einen Impfanreiz für aktuell nicht
    geimpfte Personen bieten.
    Die Risiken der Lockerungen für ausgewählte Personengruppen für die COVID-19-Eindämmung hängen unter
    anderem von der epidemiologischen Lage und der Durchimpfungsrate ab. In Bahrain und Deutschland könnten
    Lockerungen in einem Kontext höherer Inzidenz möglicherweise die Wirkung bestehender
    Eindämmungsmaßnahmen schwächen. Alle Länder die Ausnahmen gewähren, sollten Risikokommunikation
    und Community Engagement stärken, um die fortdauernde Bedeutung von Schutzmaßnahmen (AHA + L) für
    den Schutz der nicht geimpften Bevölkerung hervorzuheben.

    1.       Problem Statement
    Weekly COVID-19 incidence per 100,000 population has been increasing in Bahrain since early April 2021 and
    decreasing in Chile, France, Germany, Israel, the United Kingdom and the United States at least since late April
    2021. Meanwhile, full vaccination coverage is below 40% in all countries save Israel. Several countries have begun
    granting exemptions from COVID-19 containment measures to individuals with negative tests, those who are
    recently recovered or those who are fully vaccinated. The types of granted exemptions pose differential risks for
    COVID-19 transmission. Risks to COVID-19 containment posed by granting exemptions depend inter alia on
    the epidemiological context and the extent of full vaccination coverage.i This report describes the exemptions
    from COVID-19 containment measures for fully vaccinated, recently recovered and negatively tested individuals
    that countries have recently implemented or are planning to implement. While the risk of transmission is
    reduced in fully vaccinated individuals, in a context of continued heavy SARS-CoV-2 virus circulation and low
    full vaccination coverage, it is important to analyze exemptions across countries to assess their potential to
    weaken pandemic containment.

    2.       Epidemiological Comparison
    2.1 Weekly new COVID-19 cases per 100,000 population in Bahrain, Chile, France, Germany, Israel, the United
    Kingdom and the United States, February -May 2021: Weekly COVID-19 incidence per 100,000 population has
    been increasing in Bahrain since early April 2021. In Germany, weekly COVID-19 incidence increased in early
    April, but has begun to decrease slightly since late April 2021. Weekly COVID-19 incidence has been decreasing
    in Chile, France, Israel, the United Kingdom and the United States since early April 2021. As of 9 May 2021,
    COVID-19 incidence stands at 3.93 in Israel, 21.72 in the United Kingdom, 86.44 in the United States, 117.22 in
    Germany, 183.28 in France, 191.19 in Chile and 591.16 per 100,000 population in Bahrain (Figure 1). 1

    2.2 Variants of Concern: VOC B.1.1.7 is dominant (accounting for at least 50% of circulating variants) in France,
    Germany, Israel, the United Kingdom, and the United States. ii In the United Kingdom, VOC P.1 has been
    prevalent in 0.027% of cases between October 2020 and late April 2021. VOC B.1.617 was prevalent in 0.064%
    of cases in the country between October 2020 and late April 2021, but Public Health England reports that variant-
    associated cases have been increasing by 71% between mid- and late April 2021. iii In Germany, VOC P.1
    comprises 0% of sequenced samples and B.1.351 0.7%.iv In France, P.1 comprises 0.3% of circulating variants in
    the country as of late April. v B.1.1.7 comprises 22% of circulating variants in Chile as of April 2021. P.1 comprises
    27% of circulating variants in Chile as of April 2021.vi P.1 comprises 5% of circulating variants in the United
    States. B.1.617.1 and B.1.617.2 together comprise 0.7% of circulating variants in the country. vii No data on
    circulating virus variants was available for Bahrain.2

         1 In early April 2021, public holidays due to Easter celebrations were observed in a number of the seven countries. This
         likely affected reported incidence.
         2 Data quality on COVID-19 variants varies greatly across countries. See “Evidence Rating” in this report.

3.     Vaccination Coverage, Access, and Acceptance
3.1 Vaccination coverage in Bahrain, Chile, France, Germany, India, Israel, the United Kingdom and the United
States, February-May 2021: As of 9 May 2021, 44.8, 46, 46.9, 52.3 and 62.7 % of the population had received at
least one dose of a COVID-19 vaccine in Chile, the United States, Bahrain, the United Kingdom and Israel
respectively. By the same date, 26.4 and 32.6 % of the population in France and Germany had received at least
one dose. As of 9 May 2021, full vaccination coverage was at 9.4, 11.7, 26.3, 34, 34.2, 37.4 and 58.7 % in Germany,
France, the United Kingdom, Bahrain, the United States, Chile and Israel, respectively. Bahrain administers
vaccines by Oxford/AstraZeneca, Pfizer/BioNTech, Sinopharm/Beijing and Sputnik V. Chile administers
vaccines by Pfizer/BioNTech and Sinovac. France and Germany administer Oxford/AstraZeneca, Moderna,
Pfizer/BioNtech and Johnson&Johnson vaccines. France and Germany, as well as several other European
countries temporarily paused vaccinations with the Oxford/AstraZeneca vaccine in mid-March 2021, due to the
occurrence of rare blood clots in people vaccinated with the Oxford/AstraZeneca vaccine. viii Israel administers
vaccines by Moderna and Pfizer/BioNTech. The United Kingdom administers Oxford/AstraZeneca, Moderna
and Pfizer/BioNtech vaccines. The United States administer vaccines by Johnson&Johnson, Moderna and
Pfizer/BioNTech. Chile predominantly administers the Sinovac vaccine and a small share of Pfizer/BioNTech
vaccines. France and Germany predominantly administer the Pfizer/BioNTech vaccine, followed by the
Oxford/AstraZeneca vaccine and a smaller proportion of the Moderna vaccine. The United States predominantly
administer the Pfizer/BioNtech vaccine and the Moderna vaccine, as well as a small proportion of
Johnson&Johnson vaccines. In late April 2021, the United States paused vaccination with the Janssen vaccine to
investigate rare blood clots in people vaccinated with that vaccine. ix Information on administered vaccine types
for the remaining countries was not readily available at time of report writing (Figure 1).

3.2 Vaccination access in Bahrain, Chile, France, Germany, the United Kingdom and the United States, May
2021: Bahrain is currently offering a COVID-19 vaccination to its entire population.x Chile is vaccinating anyone
aged 38 years and older.xi Since 1 May 2021, France has been offering a vaccination to anyone aged 18 and over if
they present co-morbidities. The government estimates that it can universally offer a vaccination to the adult
population from 15 June 2021 onwardsxii. Since early April, Germany has begun providing COVID-19 vaccines
through general practices. xiii The country currently vaccinates anyone aged 60 and older, as well as specific
priority groups.xiv Germany estimates that it can universally offer a vaccination by the summer of 2021.xv By mid-
February 2021, Israel completed vaccination of priority groups and has moved to universally offer a COVID-19
vaccination to its entire population of 16 years and older. The United Kingdom is currently offering a vaccination
to anyone aged 40 and over, as well as specific priority groups.xvi In the United States, anyone aged 16 and over
can be vaccinated against COVID-1 since 19 April 20219.xvii

3.3 Vaccine acceptance in Chile, France, Germany, Israel, the United Kingdom and the United States, February
2020-April 2021: In France and Germany vaccine acceptance has overall been stable between February and April
2021, shifting from 40 to 39% and 59 to 61%, respectively. In Israel, vaccine acceptance decreased from 67 to
26% between February and March 2021. In the United Kingdom and the United States, vaccine acceptance
decreased from 77 to 66% between February and April 2021 (United Kingdom) and 48 to 39% between February
and March 2021 (United States). A journal article published in Vaccine in late 2020 reports 87% vaccine
acceptance in Chile for a nationally representative sample (Figure 1).3

     3 Survey data for France, Germany, Israel, the United Kingdom and the United States builds on nationally representative

     samples.

    4.       COVID-19 Containment Measures and Exemptions
    4.1 COVID-19 containment measures in Bahrain, Chile, France, Germany, Israel, the United Kingdom and the
    United States, February-May 2021: Between February and May 2021, regulations on COVID-19 containment
    measures varied significantly among the seven countries. International travel restrictions, restrictions on internal
    movement, cancellation of public events and restrictions on public gathering were measures most strictly
    maintained across all seven countries between February and March. Most countries tightened their measures
    relating to school closures, workplace closures, public transportation and restrictions on internal movement from
    the beginning of March. From the beginning of April to the beginning of May, there have been gradual relaxation
    of measures including school closure, workplace closure, public transportation, stay-at-home restriction and
    restriction on internal movement among all countries with the exception of Chile.4
    Germany and Chile continue to maintain strict measures on school closures at all levels. Bahrain, Israel, United
    Kingdom and USA relaxed school closure between April and May. France relaxed school closure in April but
    tightened the measure again from beginning of May. France, Israel USA and United Kingdom have relaxed
    workplace closure from the beginning of May. Germany relaxed workplace restrictions from the beginning of
    March onwards.
    Germany, Chile, France and the UK continue to have strict measures in place for the cancellation of public events
    and together with the USA maintain strict measures for public gathering. Israel has relaxed restrictions on public
    gatherings from the beginning of May and Bahrain tightened restriction on public gatherings starting April. Stay-
    at-Home Requirements remain strict and unchanged for Chile, Germany, France and the United Kingdom. The
    United States have relaxed stay-at-home requirement from the beginning of May.
    Containment measures for use of public transport have remained unchanged for Germany, Chile, United
    Kingdom and the USA since the beginning of February. From the beginning of April, Bahrain and France have
    loosened regulations on public transportation and currently have no measures in place. Israel lifted these
    measures completely in the beginning of May. Across the countries, there is a gradual loosening of restrictions
    on internal movement from the beginning of March, except in Bahrain and France. Those countries tightened
    their internal movement measures. The United Kingdom and the United States have started loosening measures
    regarding internal movement from the beginning of April and beginning of May respectively. No country has
    loosened international travel measures (Figure 2).

         4 Due to the coding scheme applied by Our World in Data, the loosening and tightening of COVID-19 containment
         measures at the sub-national level does not fully display in Figure 2. In the case of Chile, that means lifting of measures
         in March 2021 is not displayed in the heatmap.

COVID-19 Containment Measures, Issue 3 | Exemptions from COVID-19 Containment Measures

4.2 Exemptions from COVID-19 containment measures for fully vaccinated, recently recovered and negatively
tested individuals in Bahrain, Chile, France, Germany, the United Kingdom and the United States, February
2020-May 2021: The available data indicates that France and the United Kingdom are not granting any
exemptions to COVID-19 containment measures for negatively tested, recently recovered or fully vaccinated
individuals. However, both countries are discussing possible future exemptions for these groups. As a member
state of the European Union, France is planning the implementation of the EU Digital Green Certificate. There
was no data on exemptions from containment measures in Chile. The four remaining countries – Bahrain,
Germany, Israel and the United States – are granting exemptions. Germany and Israel grant exemptions for three
categories of individuals: negatively tested, recently recovered and fully vaccinated. Bahrain and the United States
are only granting exemptions for recovered and fully vaccinated individuals. All four countries provide equal
exemptions to recently recovered and fully vaccinated individuals. In the four countries, exemptions are granted
for varying types of leisure activities and international travel (i.e., no obligation to quarantine or test after
returning). Germany, Israel and the United States also granted exemptions for private gatherings. Additionally,
Germany and Israel provide for exemptions in schools and work places. In the United States, recovered and fully
vaccinated people can participate in outdoor activities without wearing masks. Furthermore, in German and
Israel individuals with a negative test may participate in different types of leisure activities (Table 1).
All countries but Chile introduced or will introduce certification schemes, including via apps, for COVID-19
vaccinations, recovery and/or testing. In February 2021, Israel and Bahrain launched a certification system –
“Green Pass” and “BeAware Bahrain App” respectively for completed vaccinations and recovery from COVID-
19. Proof of vaccination can be provided via an app or as a paper certificate. In mid-March 2021, the European
Commission also introduced a proposal for a “Digital Green Certificate” for EU member states that would serve
to reinstate freedom of movement of EU citizens if they have been either vaccinated against COVID-19, can
provide a current negative COVID-19 test result or have recovered from COVID-19. In line with this approach,
France has launched the "TousAntiCovid Carnet"-app with test certificates and vaccination certificates available
in digital and paper format to help the wider recovery of travel between EU countries. In Germany, users can
currently share their test results via the Corona-Warn-App. The United Kingdom is discussing plans for
vaccination certificates while the US is using recovery certificates (Table 1).

COVID-19 Containment Measures, Issue 3 | Exemptions from COVID-19 Containment Measures

5.   Synthesis
Weekly COVID-19 incidence has been decreasing in all countries included in this analysis but Bahrain. The
available evidence on circulation of VOC indicates that the vaccines used in the seven countries are mostly
effective against VOC B.1.1.7, B.1.351 and P.1.cxxv However, there is not sufficient evidence yet on the impact of
VOC B.1.617 on vaccine effectiveness. Vaccine acceptance is lower in France, Israel and the United States and
higher in Germany and the United Kingdom. Bahrain, Israel and the United States currently universally offer
COVID-19 vaccinations. Chile, France, Germany and the United Kingdom continue to expand vaccination rollout
to progressively younger population groups. Nonetheless, one-dose and full vaccination coverage is relatively low
in all seven countries. As of 9 May 2021, at least 44.8% of the population had received at least one dose of a
COVID-19 vaccine in Chile, the United States, Bahrain, the United Kingdom and Israel. By the same date, at
least 26.4% of the population in France and Germany had received at least one dose. As of 9 May 2021, full
vaccination was below 40% in Germany, France, the United Kingdom, Bahrain, the United States and Chile,
with full vaccination coverage in Germany as low as 9.4%. Israel had fully vaccinated 58.7% of its population as
of that date. Therefore, the vast majority of populations is currently not protected from COVID-19 and continues
to be able to transmit the virus, if infected.
The United States, Israel and the United Kingdom have progressively lifted containment measures. France and
Germany continue to maintain tighter containment measures. Bahrain presents a mix of loosening and
tightening of measures over time. France and the United Kingdom do not currently offer exemptions to COVID-
19 containment measures to recently recovered or vaccinated individuals. However, such exemptions are under
discussion in both countries. In the remaining countries, exemptions often regard access to leisure activities and
easier international travel. Most of the countries offer equal exceptions to recently recovered and fully vaccinated
individuals. The majority of the countries also provide apps to digitally certify test results and vaccination status.
The available data indicates that at least two countries that grant exceptions continue to demand mask wearing
(the United States and Germany).
Survey research conducted in Germany in early May 2021 found that exemptions for fully vaccinated and recently
recovered individuals do not incentivize non-vaccinated individuals to get vaccinated as soon as possible. On the
other hand, the same research also did not find any evidence of intended undesirable behavior in response to
exemptions, such as non-vaccinated individuals intentionally becoming infected with COVID to achieve
“recovered”-status and gain exemptions. The survey also found that non-vaccinated individuals did not wish to
abolish vaccine access prioritization if privileges to vaccinated and recovered individuals were granted.cxxvi In light
of this evidence, it is unclear if granting exemptions from COVID-19 containment measures may provide an
incentive to currently unvaccinated individuals to receive the vaccine.
Risks to COVID-19 containment posed by granting exemptions depend inter alia on the epidemiological context
and the extent of full vaccination coverage. In Bahrain and Germany, incidence is currently very high and
somewhat high while full vaccination coverage is high and low, respectively and exemptions are granted. This
potentially weakens containment measures in both countries. Irrespective of incidence, since six out of seven
countries continue to have relatively lower full vaccination coverage, all countries granting exemptions should
invest in sustained risk communication and community engagement to stress the continued importance of
protective behaviors (mask-wearing, physical distancing, hand-washing, ventilation) to protect the non-vaccinated
population.cxxvii

    6.   Evidence Rating
    The evidence presented in this report analyzes exemptions from COVID-19 containment measures for fully
    vaccinated, recently recovered and negatively tested individuals. The evidence presented in this report builds on
    data in the public domain from Our World in Data that was used to calculate weekly COVID-19 incidence and
    vaccination coverage. Our World in Data builds on epidemiological data from the Center for Systems Science
    and Engineering at Johns Hopkins University, the European Centre for Disease Prevention and Control and
    government sources. Data on prevalence of COVID-19 virus variants stems from analyses conducted by the
    Public Health Intelligence Unit at Robert Koch Institute and government sources. Data on vaccine acceptance
    stems from the Imperial College London/YouGov COVID-19 Behaviour Tacker. Data on COVID-19 containment
    measures stems from the Oxford COVID-19 government response tracker. Data on national exemptions to
    COVID-19 containment measures for fully vaccinated, recently recovered or negatively tested individuals stems
    from government sources and is occasionally supplemented with media reports.
    Data on COVID-19 incidence and vaccination coverage was available for all countries. Data on VOC circulation
    was available for six out of seven countries. The representativeness and validity of data on VOC is limited for
    Chile and Israel, good for France and Germany and very good for the United Kingdom. The representativeness
    and validity of VOC data for the United States could not be evaluated. Continuous data on vaccine acceptance
    over time was available for five out of seven countries. Data on vaccine types administered was available for four
    out of seven countries. Data on COVID-19 containment measures was available for all countries. Due to the
    coding scheme applied by the Oxford COVID-19 government response tracker, containment policies at the sub-
    national level may not be fully represented in the tracker’s data. Evidence on exemptions from COVID-19
    containment measures was complete for two out of seven countries, five out of seven countries had at least some
    missing data.
