Intranasal flu vaccine is safe

Reported by Susan Aldridge, PhD, medical journalist

A new study has found there are no serious risks associated with the widespread use of intranasal flu vaccine.
Until recently, the flu vaccine has always been given by injection. It needs to be taken yearly by those for whom a bout of flu could lead to complications, such as the elderly and those with heart problems. In the last two winter flu seasons, a vaccine in the form of an intranasal spray has been introduced and scientists from the Food and Drug Administration (FDA) now report upon its safety.

Around two and a half million people have received the intranasal spray since its introduction. There have been no fatalities but a few cases of allergic reaction and of exacerbations of asthma among those with a previous history of the condition. The FDA team therefore concludes the vaccine is safe and can be used to help protect the population from flu. However, there is a concern that it is being used in people for whom it is not indicated - the package insert indications must always be followed carefully.
