There is going to be a vaccine against all flu

Scientists at the Royal College of London (UK) say they are getting close to the possibility of finding a vaccine to prevent all types of flu after determining the role of an immune cell can resist the virus.

This is the result of a study aimed at explaining why some people are less ill than others at the time of the H1N1 flu pandemic in 2009, according to the head of the research team. Professor Ajit Lalvani, he and his colleagues collected blood donated samples of 342 staff and students in the school after the pandemic broke out.

In addition to blood, volunteers were asked to sample the nasal mucosa and provide regular information about health. Subsequent results showed that in the blood of people with severe illness with fewer CD8 T immune cells, there was antiviral function compared to those who were ill but asymptomatic or not infected with the influenza virus.

Statistics from the World Health Organization show that globally 250,000 to 500,000 people die from influenza infection each year. Although new vaccines are constantly being developed, this is not a complete solution when many new strains of influenza continue to appear.

Therefore, the team believes that, if developing a vaccine to stimulate the body to produce more immune cells CD8 T can prevent seasonal flu virus more effectively, even protect people from pandemics. dangerous in the future.
