With neighbour China seeing an unanticipated rise in Covid-19 cases, India is taking all necessary precautions and has recommended that Serum Institute of India's Covovax be approved for distribution as a booster dose.
The government drug regulatory authority, the Drugs Controller General of India (DCGI) has recommended that the Serum Institute of India's Covid vaccine Covovax be approved for distribution as a heterologous booster dosage for people who have already had two doses of Covishield or Covaxin.
However, this is not the first time this drug has come into the picture:
Covovax is a spike protein nanoparticle vaccine that was authorised for adult and paediatric usage last year. It is made using technology transferred from the American biotechnology company Novavax.
Since the Indian administration had permitted the mixing and matching of vaccines towards the end of last year, you can get Covovax if you had either Covishield or Covaxin.
In general, Covovax was given intramuscularly in two doses, with a three-week interval between jabs recommended by the Serum Institute of India. But now it will be given as a booster, so one dose is good enough.
PS: You don't need a Covovax booster dose if you already had taken one from the available options.
You can take the booster dose at any government or private vaccination centre. Notably, you have to carry your final certificate of vaccination which includes details of both first and second doses.
