Dear Pankaj,

Msc microbiology is good and attractive subject but when you study up to post doc . In all R And D department have a vaccines research team .if you really interested in microbiology you done industryal micro ,medical microbiology ,diary microbiology etc this field is very important for new products making for biotechnology company but study up to innovater or researcher level but only msc without industryal skill this field not give huge future ,I only aware you but choice is yours.

I think it's helpful for you.
