Covaxin and Sinopharm and also that the trials tested two slightly different viral
vector vaccines which use genetically engineered adenoviruses to produce corona
virus proteins in the body on 76 volunteers. We outline the essential Vaccines

which are denied to use the vaccines. And also the approval of the countries and
mainly the Covaxin is yet to introduce the vaccines through nasal route is the
