In the CDC’s words

What the CDC says about flu shots and spread

“For most people who need only one dose of influenza vaccine for the season, September and October are generally good times to be vaccinated against influenza. Ideally, everyone should be vaccinated by the end of October.”
CDC, Who Needs a Flu Vaccine, Sept. 18, 2025, quoted exactly.
“Everyone 6 months and older should get an annual flu vaccine, ideally by the end of October but people should continue to get vaccinated as long as flu viruses pose a threat to their community.”
CDC, Preventing Seasonal Flu, Sept. 1, 2026, quoted exactly.
“Most experts think that influenza viruses spread mainly by droplets made when people with flu cough, sneeze, or talk. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.”
CDC, How Flu Spreads, Sept. 17, 2024, quoted exactly.
“People with flu are most contagious during the first three days of their illness.”
