Question

Write in detail about composition and uses of covid vaccines being used in Gujarat?​

Answer 1

Answer:

Yes. There are three COVID-19 vaccines for which certain national regulatory authorities have authorized the use. None have yet received WHO EUL/PQ authorization but we expect an assessment on the Pfizer vaccine by the end of December and for some other candidates soon thereafter.  

Large studies of 5 vaccine candidates efficacy and safety results, including these three (and for Moderna and AstraZeneca), have been publicly reported  through press releases but only one (AstraZeneca) has published results in the peer reviewed literature.  , We expect more such reports in the near future.  It is likely that additional candidates will be submitted to regulatory authorities for approval. There are many potential COVID-19 vaccine candidates currently in development.
