Seasonal flu happens every year and the virus changes every year - but many people have some immunity to help the infection of the virus circulating in the limit
However, influenza A (H1N1) is a new virus and that most people have little or no immunity and the virus can cause infections is more than seasonal influenza. WHO works closely with manufacturers to develop a safe and effective vaccine to accelerate, but there are still a few months before it is available.
