We have just returned from the Arcadia and visited Mumbai - we checked with our GP and there were no compulsory injections but they recommended we update our Polio, Tetanus, etc (free) and also had the Hepatitis A vaccination (free) - we did have both of these and asked about malaria tablets but were advised that would be unnecessary for Mumbai area.
Just returned from Arcadia Southampton to Mumbai. I stayed in Mumbai for 4 days and checked with MASTA and no caccinations were compulsory nor were Malaria Tablets. So I did not have them. Mumbai and the Taj Mahal Hotel were wonderful.
