People who are fully vaccinated against COVID-19 may now make plans to get a Pfizer or Moderna shot as a booster dose, regardless of which combination of vaccines they received for their first two shots. However, the booster dose should be administered at least 3 months after the most recent jab.
According to a new guideline for booster shots, endorsed on December 13, 2021 by the Center for COVID-19 Situation Administration (CCSA), people inoculated only with AstraZeneca shots will be able to receive either a Pfizer or Moderna booster dose 3-6 months after their latest jab. Those who were “cross-vaccinated” with combinations of Sinovac, Sinopharm, and AstraZeneca shots will also receive Pfizer or Moderna shots for the booster dose.
Meanwhile, people who were fully inoculated using either the Pfizer or Moderna shots will need to wait for 6 months until getting the booster, which will also be either a Pfizer or Moderna jab.
The CCSA plans for 23 million booster doses to be administered within March 2022 so that people’s immunity against the coronavirus can be kept heightened.
Prime Minister’s Office spokesperson Thanakorn Wangboonkongchana explained that the government has now set a target of acquiring 120 million doses of Covid vaccine from AstraZeneca, Pfizer, and makers of protein subunit-type vaccines. The aim is for vaccine coverage to reach 80% of the population. (NNT)
