Only about four in 10 U.S. adults got a flu vaccine last year, less than last year and in previous years, according to a new report from the Centers for Disease Control and Prevention.
The new analysis, which encouraged doctors to recommend and offer flu vaccines, presents a fuller picture of the 2017-2018 flu season, which was the deadliest in four decades.
Lower vaccine rates were consistently across adults of many ages, the study found, with vaccine coverage among all adult age groups coming at the lowest levels in seven flu seasons.

The new CDC report estimated influenza vaccine coverage based on its Behavioral Risk Factor Surveillance System, which uses telephone surveys to track health data in all 50 states.
The study had some major limitations, including that of respondents self-reported vaccination status, and that response rates declined.
Notably, other government data sources – including other surveys and Medicare claims data – do not appear to show decreases in influenza vaccine coverage, the study noted.
