Universal Flu Vaccine Successfully Tested

Scientists at Oxford Jenner Institute have developed a universal flu vaccine that could protect against all known strains for up to 10 years. This vaccine uses internal proteins from the virus, which remain constant, unlike the outer proteins that change frequently. Early tests show promising results, suggesting that the vaccine could reduce the severity of flu and prevent pandemics. The vaccine could be administered at any time, reducing the seasonal rush for flu shots. Further studies are needed to confirm its effectiveness in a larger population.
