Information published by scientists at the World Health Organization's Reference and Research Center (WHO) in Melbourne, Australia, published October 21 online in the scientific journal. European Union Eurosurveillance.

Scientists say the influenza A / H1N1 virus has had a clear genetic change since it developed into a global pandemic in 2009. These variants were first discovered in Singapore in early 2010, after that spread throughout Australia and New Zealand.

The level of virus variability is not so strong, but there have been some cases of people being vaccinated against influenza A / H1N1 still infected, even some cases have died.

According to scientists, the new strain may have combined with some common vaccine-resistant strains of influenza virus in adolescents and adults who received monovalent influenza vaccine (only for influenza A / H1N1) from the beginning. year to date, as well as in people where virus variants have been isolated.

Scientists insist that there is not enough information to confirm there are other factors that make people more susceptible to A / H1N1 influenza virus, and affirmed that more research is needed to determine whether the new variant is possible. Is it more likely to cause death, and whether the A / H1N1 flu vaccines are currently effective against the new strain?

Flu strains often change, forcing the world pharmaceutical industry to develop new vaccines every year.

Although the influenza A / H1N1 virus has remained almost unchanged since the outbreak of this pandemic in March 2009, the virus has spread very quickly, spreading all over the world within a few weeks, and is mainly fatal in the bar. , youth.
