New Delhi: India is planning to do a study on the efficacy of COVID-19 vaccination if two different coronavirus vaccines are administered to a patient for their two doses. This comes after several reports of a massive shortage of COVID-19 vaccines in the country. “India may in few weeks start testing the feasibility of a regimen that mixes two different doses of COVID vaccines to see if it helps boost the immune response to the virus," said Dr N K Arora, Chairman of COVID-19 working group under the National Technical Advisory Group on Immunisation (NTAGI). Earlier, in Uttar Pradesh’s Siddharthnagar district, due to medical negligence, 20 people were administered the first dose of Coveshield and the second dose of Covaxin.
