Hi,
Indian govt have not cleared their stance over making vaccination mandatory yet. Brazil's president recently announced that vaccination won't be made mandatory in the country. A similar move was announced by epidemiologist and US Infectious Disease Expert, Dr Anthony Fauci. A recent survey also pointed out evidence that 35 per cent of Americans wouldn’t get a COVID-19 vaccine even if it were free. And if we follow the stance of Indian Government and ICMR, in one of their recent interviews, they've already said that 'not everyone will receive vaccine." Unclear, but anything can be speculated through these statements.
Moreover, not making it mandatory for everyone will not rule out the chances that there are certain jobs/places where it can be made compulsory. For example, health worker in hospital, school children, etc. Even previous doses of vaccine which were used to diagnose hepatitis B, polio, etc., were essential for public good, but not mandatory.
