When shоuld I get vаccinаted аgainst flu? Fоr mоst people who need only one dose of flu vaccine for the season, September and October are generally good times to be vaccinated against flu. Ideally, everyone should be vaccinated by the end of October. Additional considerations concerning the timing of vaccination for certain groups of people include: Most adults, especially those 65 years and older, and pregnant people in the first or second trimester should generally not get vaccinated early (in July or August) because protection may decrease over time. However, early vaccination can be considered for any person who is unable to return at a later time to be vaccinated. In the paragraph under the heading "When should I get vaccinated?", does the CDC provide any references to support the claim that early vaccination is associated with reduced protection against flu virus in older adults?
