The Brihanmumbai Municipal Corporation’s (BMC) Nair hospital is facing a new hurdle in its vaccine trial for children, as most of them fail the eligibility criteria of being negative for Covid-19 antibodies. 

The hospital had started the clinical trial of two-dose Covovax vaccine for children aged 2-17 years earlier this month. It has to enrol 920 children for the trial. So far, they have managed to recruit and vaccinate only nine children. The second dose of Covovax, a vaccine developed by US-based Novavax and being produced in the country by the Serum Institute of India, has to be given 21 days later.
