The vaccination centre at Bangkok’s Bang Sue Grand Station will provide free COVID-19 booster vaccination shots to the public throughout August.

Those interested in getting booster shots of Pfizer or Moderna vaccines, can make advance appointments, starting tomorrow (Wednesday), by registering online through the four mobile phone service providers:

AIS at www.ais.th/vaccine

True at https://vaccine.trueid.net/ or through USSD system, then press *707# and make the call

DTAC at https://app.dtac.co.th/vaccine/index.html or DTAC app

NT at https://covid19vaccine.ntplc.co.th/CVC/home

Those who are unable to make advance bookings can walk in to receive vaccinations every day between 9am and 4pm, with registrations made at the site.

The Moderna vaccine is for people who are 18 and over.

For those who prefer AstraZeneca or Sinovac vaccines, as well as children aged over 5 for their first and second doses, the service will be available as walk-in only.

The third dose will be administered 90 days after the second dose and the fourth dose will be 120 days from the third.

More than 30 million booster doses have been administered in Thailand to date, according to the Centre for COVID-19 Administration Situation (CCSA).
