Information Regarding the 3rd Dose of the COVID-19 Vaccine

The COVID-19 vaccine has high preventive effectiveness. However, the vaccine effectiveness wears off as time passes. That is why you need the 3rd dose, known as the booster shot.


Who is eligible?

You must be 12 years or older and wait for five months after your 2nd dose.


Free of charge


Vaccination sites or medical facilities in your city/town/village


It is known that the 3rd dose of the vaccine has high preventive effectiveness of getting infected with COVID-19 or getting seriously ill even if you have gotten infected.

The 3rd dose can be from another manufacturer which is different from the 1st and 2nd doses. It is highly effective and safe. You will probably have similar side effects as the ones you had after your 2nd shot, regardless of the manufacturer. Those side effects should be fewer than those of the 2nd shot because the 3rd dose of the Moderna vaccine is half the dose of the 1st and 2nd shots.



◆ The 3rd dose is recommended to receive even for those people who have been infected with COVID-19 before.

◆ Even after your 3rd dose, you are requested to take anti-infection measures.

◆ Do not force those people around you to get vaccinated.

◆ Do not discriminate against unvaccinated people.
