Boosters less effective against more prevalent BA.2 subvariant: Dr Yong

Boosters less effective against more prevalent BA.2 subvariant: Dr Yong

FRIDAY, April 29, 2022

Booster shots provide 1.7 times less immunity against the Omicron BA.2 subvariant compared to the BA.1 subvariant, top virologist Dr Yong Poovorawan said on Friday.

In a Facebook post, Dr Yong said a recently conducted study shows that nearly all current Covid-19 patients in Thailand had been infected by the BA.2 subvariant.

The study, “Omicron BA.1, BA.2 and Covid-19 booster vaccination”, was published on Wednesday in the peer-reviewed Journal of Infectious Diseases.

His report also concludes that the mutation of the virus causes the immunity to drop slightly.
