hello today i will be interviewing bob Jonson a GP about vaccines and how safe they are.
a vaccine is something that is put into your body to immunization your body to a certain disease.
so the first question i suppose is what are vaccines?
a vaccine works by putting a dead pathogen into our body and this tricks our body to think that we are being attacked by a virus or bacteria, this makes the body produce antibody to fight the pathogen.
Ok so secondly how do they work?
Well, as you know the most common way is to inject them with a needle, but not all people like that so other ways have been developed. the flu vaccine now is strayed up children's noses but other vaccines can be put into a sugar pill for people to eat.
