Some people have expressed concern about needing a second flu vaccine if they were vaccinated early in the fall. One flu vaccine is protective for the entire flu season and a second dose is not recommended for adults.
An MMWR from August 2010 notes that “additional vaccine doses during the same season do not increase the antibody response” and that the “frequency of breakthrough infections is not known to be higher among those who were vaccinated early in the season.”
Two doses of flu vaccine are only recommended for young children who have never been vaccinated before. Children younger than 9 who have never had a seasonal flu vaccine should receive two doses, spaced at least 4 weeks apart.
