Covid-19 Vaccines and their Interchangeability Could be Effective in Developing Countries Like India to Generate Stronger Adaptive Immune Response in Large Population

Vaccine considered as a boon for every individual across the world in the time of pandemic situation. India has developed its own vaccine which shows promising results. Receiving vaccine does not mean that we are completely immune to the disease. Covishield shows some rare but adverse side effects of blood clots in those people having thrombocytopenia. Covaxin has not recorded any such cases as it is of inactivated type. But, the manufacturers of the vaccine have not established the longevity of protection against COVID-19. Unavailability of vaccines in India could pose a serious impact on the lives of the people. Government of India and Medical authorities should take clinical trials and make decision on interchangeability of vaccines as soon as possible.
