India may soon begin investigating the feasibility of combining two Covid-19 vaccines to determine whether it might assist increase the immune response to the virus. According to The Indian Express, the testing might be done with vaccines that are now available in the country as well as those that are in the process.
According to Dr. N K Arora, chairman of the Covid-19 working group within the National Technical Advisory Group on Immunization, work will begin “in a few weeks” (NTAGI). As part of the process, around eight vaccines may be mixed and matched, according to Dr. Arora. These include the three vaccines currently approved for use in India: Covishield from the Serum Institute of India, Covaxin from Bharat Biotech, and Sputnik V from Russia.
Collaboration between agencies like the Indian Council of Medical Research and the corporations that designed and produced the vaccines might be used to conduct clinical testing as part of the exercise. The tests will look into things like whether different platforms of vaccines can be administered together and which vaccines to deliver in the first and second doses.
