Vaccinations can cause health problems (illness or disability). Although this is extremely rare, the risk cannot beeliminated, and a relief system has been established for this reason.
In case health damage occurs from COVID-19 vaccination, the relief system (medical expenses, disability pension
benefits, etc.) is available under the Immunization Act *.
Please consult the local municipality regarding the procedures required for application.
* When the Minister of Labour, Health and Welfare certifies that the health damage comes from COVID-19 vaccination, benefits will be provided by thelocal municipality. For certificate, the Examination Committee for Certification of Sickness and Disability, which is composed of specialists of vaccination,
infectious disease, medical, and legal experts, determines the causal relationship between the vaccine and the health damage.

For COVID-19 vaccines, two doses are required.

● If you are receiving the first dose,・You will have to receive two doses of a same vaccine with a certain interval in between in order to get sufficienteffect of the vaccine.
・After the first dose (today), a second dose is usually administered after 3 weeks. Do not leave too much interval
after 3 weeks.
・As for the reservation of the second dose, please follow the instruction given by the medical facility where you
had your first shot or consult the local municipality.
・Depending on the symptoms occurring after the first dose, sometimes it is better not toreceive the second dose. If you have had any symptom of concern, please ask the medical

Please continue taking infection prevention including wearing a mask even after you havefinished receiving the vaccine.
It is expected that the vaccine can prevent onset of COVID-19, but it is not known how well it can prevent the spread ofinfection to others. While the vaccination is still going on, not many people can be vaccinated immediately, and both those
who have been vaccinated and those who have not been will keep on living together in this society.
Therefore, we ask you to continue taking infection prevention.
Specifically, please avoid "three C’s (closed spaces, crowded places, close contact settings)", wear a mask, wash yourhands with soap, and disinfect with alcohol for hand disinfection.
