their backing that it is fine is teh fact that it is NOT a "LIVE" vaccine so this means it contains no active part of the infection ( H1N1 influenza) but allows teh body to trick itself and produce antibodies against it. basically we are not injecting the virus into you but the chemical make up for teh antibodies.

and with studies done on other non activated vaccines they have show now ill effects on pregnant women. so the theory is if its not live its safe for use.

this vaccine shouldnt be given to people with an allergy to egg as it is made on a product which is based on chicken protein or has had an anaphylactic hypersensitivity to previous vaccine.
