The booster vaccination program has been started since 2021 , for the world community. Given that most people use Sinovac vaccine during the first and second doses, many are asking what booster vaccine is suitable for Sinovac.
A booster vaccination is a COVID-19 vaccination after a person has received a complete primary dose of vaccination aimed at maintaining the level of immunity and extending the period of protection.
The recommendations for booster vaccine combinations are as follows:
Sinovac's first and second vaccines will be given a half dose of Pfizer's booster vaccine
Sinovac's first and second vaccines will be given a half-dose booster vaccine of AstraZeneca
AstraZeneca's first and second vaccines will be given a half dose of Moderna's booster vaccine.
The combination of booster vaccines is also in accordance with WHO recommendations where the booster vaccine can use the same vaccine (homologous) or different vaccines (heterolog).
