Keep in mind that vaccination is especially important for certain people who are at high risk or who are in close contact with high-risk persons.
This includes children at high risk for developing complications from flu illness and adults who are close contacts of those children.
Flu illness is more dangerous than the common cold for children. Each year, millions of children get sick with seasonal flu; thousands of children are hospitalized and some children die from the flu. Children commonly need medical care because of flu, especially children younger than 5 years old who become sick with flu.
According to The CDC, Children should be vaccinated every flu season for the best protection against flu.
For children who will need two doses of flu vaccine, the first dose should be given as early in the season as possible.
For other children, it is good practice to get them vaccinated by the end of October. However, getting vaccinated later can still be protective, as long as flu viruses are circulating.
It is best that people get vaccinated so they are protected before influenza begins spreading in their community.
