The vaccine does not coincide with flu-like illnesses that appeared close to the end

The flu vaccine turned out to be a big disappointment again.

The vaccine has not responded to flu flu that appeared in the last part of the flu season, lowering its efficacy rate by 29%, said Thursday at the US Center for Disease Control and Prevention.

Inflammation was also early in the season, and its efficiency was 47% in February. But it was practically worthless, while the second wave, driven by heavy load, was only 9%.

"No significant protection" against that soy, said CDC, Brendan Flannery.

Flu vaccines are given each year to protect three or four different types of flu viruses. Ingredients are based on predictions of what people do to the sick next winter.

This season it turned out that the video was incompatible with the bug, which appeared too late.

This has reduced the overall impact on one of the lowest in recent years. Since 2011, the season is only lower with a lower estimate in the winter 2014-2015, when the efficiency was 19%. Then the guilty was a conflict.

Vaccines against some other contagious diseases will not be considered successful unless you are at least 90% effective. But flu is particularly demanding, partly because the virus can change so quickly. Overall, the flu vaccine averages 40%.

A flu vaccine is recommended to almost all Americans at the age of 6 months or older. Officials say the vaccine is still valuable because it works against some strains and will probably prevent 40,000 to 90,000 hospitalizations during the winter season flu.

CDC is based on the effectiveness of a vaccine to prevent cases that are bad enough for someone to send a doctor.
