NEW DELHI : A senior expert at the All India Institute of Medical Sciences (AIIMS) has come out against the government policy of mixing covid-19 vaccine doses, warning that in case of an adverse event it will be very difficult to establish which vaccine caused it.
Mint reported on Tuesday about government plans to open up covid-19 booster doses to all adults, marking a dramatic scale-up in the vaccine’s rollout that will make tens of millions more eligible to receive the precautionary jabs.
Mixing and matching will lead to no accountability of pharmaceutical companies in case of any adverse effect, said Sanjay Rai, professor of community medicine at AIIMS.
He called for more scientific studies to establish the efficacy and safety of mix-matched vaccines. Globally, 33 vaccines have been approved for mix-match doses.
