In recent years, fewer and fewer people have received flu shots, amid the deadliest flu season in decades



Only about four in ten US adults received a flu vaccine last year, less than in the previous year and in previous years, according to a new report from the Centers for Disease Control and Prevention.

The new analysis, which encouraged physicians to recommend and offer flu vaccines, presents a more complete picture of the flu season 2017-2018, which was the deadliest in four decades.

Lower vaccination coverage was consistent among adults of all ages, the study found, with vaccine coverage at lowest levels among all adult ages in seven flu seasons

An estimated 37% of adults in the US received a flu vaccine during the 201

7-2018 flu season, down about 6% from the previous year, according to the CDC.

This year's flu season has already begun. The CDC recommends that everyone who is at least six months old be vaccinated until the end of October; Most adults tend to take flu shots at the end of November, according to the new study.

Influenza vaccines protect against the disease by stimulating the formation of protective antibodies in the body. They have to be administered every year and are available everywhere in doctors' offices, pharmacies, health centers and even in many offices.

It generally takes about two weeks after vaccination that antibodies develop, according to the CDC.

In each season the flu varies in both severity levels and what type of flu virus is most common. Influenza vaccines are designed in this sense; However, efficacy may vary, in part because manufacturers often need to find out which viruses are likely to dominate the January flu season in January.

The new CDC report estimated influenza vaccine coverage based on its behavioral risk factor monitoring system, which uses telephone surveys to track health data in all 50 states.

The study had some important limitations, including the fact that respondents themselves reported vaccination status and that response rates were decreasing.

Remarkably, other government data sources, including other surveys and Medicare data, do not appear to show any decline in flu vaccine, the study said.
