The vaccine against seasonal flu would protect against influenza A

A Mexican study released yesterday shows that people have been vaccinated against seasonal influenza have less chance of contracting the H1N1 virus.

Until now, most studies showed that vaccination against seasonal flu does not protect or little people against the H1N1 virus. Hence the need to be vaccinated twice: first against seasonal flu, the second against its variant A.

A study contradicts these theories. According to a team of Mexican researchers, "seasonal vaccination may protect against the most severe forms of the disease."

Made about 250 people from March to May 2009, the research shows that 29% of unvaccinated people have developed the swine flu, against 13% in vaccinated individuals. According to scientists, non-infected with H1N1 were more often vaccinated against seasonal flu than others.

Indeed, vaccination increased antibody levels and strengthens the immune system of patients.

However, researchers at the National Institute of Public Health Cuernavaca specify today in the British medical journal that "these results should be considered carefully and do not indicate in any way that the vaccine against seasonal influenza vaccine should replace the against pandemic influenza A (H1N1) 2009. "

The scientists also explained that their sample was limited to the extent that it was only patients from a hospital specializing in respiratory diseases and it would be necessary to "conduct similar studies in other frameworks confirm or refute these results. "
