A new strain of flu? Here's how to protect yourself this coming winter

The flu season has arrived earlier than expected due to the H1N1 strain with the G155E mutation, which reduces vaccine effectiveness in preventing infection. Experts recommend getting vaccinated as soon as possible, especially for those under 25, as the vaccine still protects against severe illness, hospitalization, and death.

The flu season has arrived this year earlier than expected, about two and a half months ahead of the usual time, due to a dominant strain of the H1N1 virus that has undergone a new mutation called G155E. The mutation spread after the vaccine had already entered production, so its effectiveness in preventing infection is reduced. However, experts emphasize that the vaccine is still essential and protects against severe illness, hospitalization, and death, comparing it to a 'seatbelt'. The recommendation is to get vaccinated as soon as possible, especially for those under 25, who are at higher risk due to lower natural immunity to this strain.
