Mutated H3N2 Flu Virus Circulates, Prompting Vaccine Considerations for Winter
A new mutated version of the H3N2 flu virus, referred to as the 'subclade K', is circulating earlier than usual this year, raising concerns about a potentially severe flu season. The NHS has issued a 'flu jab SOS' to vulnerable groups, including those over 65, pregnant women, and individuals with certain health conditions, urging them to get vaccinated. The flu vaccine, which is available for purchase at high street chemists, is recommended even for healthy individuals to protect against this strain. The vaccine takes up to 14 days to become effective, and while it does not cause the flu, it prepares the body to fight the virus. The vaccine is updated annually to match the expected circulating strains.
