NEW DELHI: Even as the Hyderabad-based Bharat Biotech waits for the much sought-after emergency use authorisation (EUA) from the World Health Organization (WHO) for its indigenous Covid-19 vaccine ‘Covaxin’, it seems that the wait is to continue for at least a bit longer. The international public health body is likely to have once again delayed its approval for the Covaxin shot, this time till October 5. According to a report by the ANI news agency, the Strategic Advisory Group of Experts on Immunization (SAGE) will be meeting on October 5 to decide on granting the EUA to Covaxin.
