The government has approved Biological E’s Corbevax as a precaution dose or booster jab for those above 18 years fully vaccinated with either Covishield or Covaxin, official sources said today.This is for the first time that a booster dose that is different from the one used for primary vaccination against Covid has been allowed in the country.
The sources told Press Trust of India that the Union Health Ministry’s approval is based on the recommendations made recently by the COVID-19 Working Group of the National Technical Advisory Group on Immunisation (NTAGI).
Corbevax will be considered as a precaution dose after completion of six months or 26 weeks from the date of administration of the second dose of either Covaxin or Covishield vaccines for those aged above 18 years enabling use of Corbevax as a heterologous COVID-19 vaccine for precaution dose administration in this age group,” the sources told Press Trust of India.
The COVID-19 Working Group (CWG), in its July 20 meeting, reviewed data of the double-blind randomised phase-3 clinical study which evaluated the immunogenicity and safety of booster dose of Corbevax vaccine when administered to COVID-19-negative adult volunteers of age 18-80 years previously vaccinated with two doses of either Covishield or Covaxin.
