Which age groups are prioritized for influenza vaccination due to higher risk of complications?

• A. Young children under 5 and older adults, plus those with chronic conditions
• B. Teenagers and healthy adults
• C. Infants under 6 weeks
• D. Adults over 65 only

Answer: (A)

Prioritizing vaccination for groups most at risk of influenza complications. Young children under 5, older adults 65 and older, and people with chronic health conditions are the groups most likely to experience severe illness, hospitalization, or death from the flu. Vaccinating these groups helps prevent serious outcomes and reduces the burden on healthcare systems, especially when vaccine supply is limited. In practice, the vaccine is recommended for everyone 6 months and older, but emphasis on these high-risk groups explains why this option is the best fit. Infants younger than 6 months cannot be vaccinated, so protection for them comes from herd protection and from caregivers and close contacts who are vaccinated. Teenagers and healthy adults, or adults over 65 only, don’t capture all the high-risk groups, so they aren’t the most accurate emphasis for prioritization.
