On Thursday, health experts have said that about half of the U.S population has not being vaccinated against influenza. The virus kills thousands every year. Kids who are healthy and get the virus, can die in the intensive care unit. Women who are pregnant are at risk too. This is because people do not vaccinate their children against the flu. The CDC claims that last season, that out of 100 children killed by flu, 90 of them were not vaccinated against it.
The number of adults vaccinated in the U.S has been picking up. Doctors and nurses are required to be vaccinated against the flu.
