SWINE FLU VACCINE 'BY SEPTEMBER'

The first swine flu vaccines are likely to be licensed for use in the general population in September, the World Health Organization has announced.

 

Several manufacturers have produced initial batches of a H1N1 vaccine and some clinical trials are already underway. WHO director of vaccine research Dr MariePaule Kieny also sought to calm fears about safety of new vaccines. She said the vaccines were based on "old and proven technology".

 

Although it has not yet been clarified who would be first in line for a vaccine, it is likely to be those who are most vulnerable, such as pregnant women and young children. Some experts have raised concerns about the lack of safety data on flu vaccines in these groups. In particular, a very rare neurological condition called Guillain Barre syndrome affected 500 people during a US vaccine program against swine flu in 1976.

 

Dr Kieny said much was known about flu vaccines in these groups from seasonal vaccines given every winter and added that regulatory agencies would be monitoring for any signs of adverse reaction. "The quality controls on today's vaccine are much better than they were 30 years ago," she added.

 

Regulators in the US and Europe have special plans in place to fast-track swine flu vaccines, some of which are based on conventional seasonal flu vaccines and some which use newer technology. Clinical trials are already underway in China, Australia, USA, UK, and Germany. One key part of the trials is to work out whether people need one or two doses of the vaccine.
