Flu vaccines are not as effective as we believe, medical experts say. More than half of those who get shots don't have full protection against infection, as vaccines don't shield them from newer strains of the virus.
As many as 65 percent of people who received flu shots last winter did not get the protection they expected from the vaccines. According to the National Institute for Health and Welfare the THL, the viral anti-agent used for the past three years no longer protects against new strains of the virus.
Helsinki University Hospital's medical chief of infectious diseases Veli-Jukka Anttila said that the last season saw the emergence of an H3N2 type virus, which was rife in senior patients in long term care wards and in primary health care stations. Some of them had received flu shots.
