‘SINGAPORE - Though often considered inferior due to their induction of a lower antibody response compared with their mRNA counterparts, inactivated virus vaccines can play a role in preventing the development of severe Covid-19, a recent study has found.

The study by the Duke-NUS Medical School found that inactivated virus vaccines such as Sinopharm and Sinovac, which were used extensively in Asia, and mRNA vaccines – which include Pfizer-BioNTech’s Comirnaty and Moderna’s Spikevax – trigger different T-cell responses in fighting the coronavirus.’
