#GS3 #Science&Technology


Hyderabad-based Bharat Biotech has said it would be manufacturing up to a billion doses of a single-dose intranasal Covid-19 vaccine in collaboration with the Washington University School of Medicine in St Louis, Missouri.


What is ‘intranasal vaccine’?

  • Vaccines are delivered through different routes, with the most common being injectable shots delivered into the muscles (intramuscular) or the tissue just between the skin and the muscles (subcutaneous).
  • Other routes of delivery, especially in some vaccines for infants, include administering the liquid solution orally instead of injecting.
  • In the intranasal route, the vaccine is sprayed into the nostrils and inhaled.
