* Beginning with the data released for September 1, 2022, the population data used to calculate the percentage of the population that has been vaccinated has been updated to the Basic Resident Registration data as of January 1, 2022. In addition, in calculating the percentage of the population that has been vaccinated, the total number of doses excludes all doses administered within 2021 to people who have died.

** Regarding the third and fourth doses, the figures for the total number of doses administered and the number of doses administered to the elderly include the number of doses administered of the vaccin e that targets the Omicron strain.

COVID-19 vaccines have shown substantial effects.

It has been confirmed that after a second dose, the COVID-19 vaccine administered to you has an
efficacy of roughly 95% in reducing the risk of developing symptoms (the onset of symptoms) such as
fever or cough.

The vaccine has been confirmed as being highly effective in preventing the onset of symptoms even in
the elderly and people with underlying health conditions such as high blood pressure or diabetes.

COVID-19 vaccines will not only benefit you but also be an important instrument in reducing the
burdens on medical institutions.

Many aspects of COVID-19 remain unknown. By the end of April 2021, roughly 590,000 people in Japan
have been diagnosed with COVID-19 infections, of which more than 10,000 people have died. (The
percentage dying or needing intensive care is approximately 1.6% [0.3% for people under 60 years of
age and 8.5% for people aged 60 or above].)

The Government recommends that people get vaccinated because the benefits of vaccination are greater
than the risk of side reactions.

Vaccination may result in the body reacting to the vaccine through local reactions that include pain
in the area where the shot was administered and systemic reactions such as fever or headaches. These
reactions are more frequent after the second dose than the first dose and the older the recipient is,
the less frequently they occur. It is best to be vaccinated when your physical condition is
essentially fine and to take things easy after receiving the vaccine.

People with a history of severe allergic reactions, including anaphylaxis, will be observed for longer
than usual (30 minutes) after the injection is given, and should anaphylaxis occur, necessary
treatment will be provided by medical workers.

The Government recommends that people get vaccinated because at present, serious safety concerns have
not arisen and the benefits of taking the vaccine outweigh the drawbacks of side reactions.

The Government will continually confirm the safety of the vaccines and provide safety-related

When granting approval to the COVID-19 vaccine, the Government examined comparative trials (clinical
trials) involving tens of thousands of people in total to confirm that serious side reactions did not
occur after vaccination. In order to continually confirm vaccine safety even now that approval has
been granted, when anaphylaxis or serious symptoms suspected by a doctor to be connected to the
vaccination arise, these cases will be reported and experts will assess the situation, in accordance
with the law. These reports will include cases such as the worsening of underlying conditions or death
after vaccination in which a causal relationship with the vaccination cannot be immediately assessed.
In such cases the Government will gather a wider range of information and conduct an assessment.

The COVID-19 vaccine will be available free of charge.

The costs of vaccination for all Japanese nationals and all eligible foreign residents, will be
covered in full by public funds.
Vaccines will never be administered without the recipient’s consent. We urge the public never to
coerce vaccinations at the workplace or upon others around them, and never to treat those who have not
received the vaccine in a discriminatory manner.

The entire government is working in an all-out manner to expedite vaccinations.

The Government will make all-out efforts to provide local governments with enough vaccine doses by
the end of June to enable all elderly persons desiring it to receive their second dose, with the end
of July in mind. We will also begin broadly inoculating the general public, including people with
underlying health conditions, starting from those municipalities that have prospects for finishing
vaccinations of the elderly.
