After getting queries from general population, near and dear ones, friends and relatives as well as from medical professionals in small towns and rural India on different aspects of vaccines for prevention of Covid-19, I have come with my second book – Corona Vaccines: Confusions & Curiosities as 2nd edition of JUST SWITCH OFF CORONA, and is again getting launched on Amazon. It has a collection of authentic facts from WHO, CDC, US NML, NCBI – the National Centre for Biotechnology Information, and different guidelines from MOHFW, ICMR and NCDC on Covid and covid related vaccines. Purpose is to answer confusions n myths about Covid vaccines and presenting an Overview on different Covid vaccines in use, along with recent updates on Omicron (to add to the 1st edition).
