Flu vaccinations can prevent people living in the same household as infected individuals from contracting secondary influenza, particularly if the pathogen is influenza B virus.
About one in five people who live in the same household as an individual infected with the influenza virus develop secondary infections within a 7-day follow-up period, with children facing the highest risk. Vaccination lowers the risk of contracting the infection among household contacts.Researchers conducted a prospective cohort study of data between 2017 and 2020 to determine the estimated effectiveness of influenza vaccines in preventing secondary infections in household contacts.
The risk for secondary infection and vaccine effectiveness in preventing infection among household contacts was estimated overall and by virus type, subtype, and lineage.Nearly half of primary cases were from children and teens between ages 5 and 17 years. The overall risk for secondary infection among unvaccinated household contacts was 18.8%, with the highest risk observed among children younger than age 5 years .
