There is a significant risk of “vaccine breakthrough” with the Sinovac vaccine, or CoronaVac, with international evidence showing that many who had taken it were later infected with COVID-19, said the Ministry of Health’s (MOH) director of medical services Kenneth Mak on Friday, 18 June 2021.
Associate Professor Kenneth Mak said that Singapore has been assessing the experience of countries such as Indonesia, which has vaccinated a “larger proportion” of the population using CoronaVac.
