A: Children from 6 months to 8 years getting the flu vaccine for the first time need to get two doses in order to maximize having a good immune response. If it's your child's first time, she still needs two doses.
In general, the flu vaccine works best among healthy adults and children older than 2 years of age. Reduced benefits of flu vaccine are often found in studies of young children (e.g., those younger than 2 years of age) and older adults (e.g., adults 65 years of age and older).
