KKH's Covid-19 study finds high antibody levels in children after they received 2 vaccine doses

Interim analysis of the Covid-19 vaccination trial on children aged between five and 11 at KK Women’s and Children’s Hospital (KKH) found that those who received paediatric doses of the Pfizer-BioNTech (Comirnaty) vaccine developed high antibody levels. 

Associate Professor Kenneth Mak, director of medical services at the Ministry of Health (MOH), said at a press conference on Friday (Jan 21) that the first cohort of 50 children developed 64 per cent antibody level after the first dose of the vaccine.

This increased to 96 per cent after their second dose, which was taken 21 days later.

Assoc Prof Mak, who is part of the Government's Covid-19 task force, said that there were some reported reactions to the vaccines during the trial but they were all minor.

The reactions included pain at the injection site, body aches, fever and minor allergic reactions.
