How Often Should Children Get a Flu Vaccination?
Children should receive a flu vaccination every year, as the flu virus strains commonly circulating in the community can change from season to season. Annual vaccination is necessary because immunity from the previous year’s vaccine wanes over time, and the flu virus undergoes mutations, rendering past vaccines less effective against new strains. The Centers for Disease Control and Prevention (CDC) recommends that all children aged 6 months and older receive an annual flu shot to ensure they are protected against the most current strains of the virus.
For children under the age of 9 who are receiving the flu vaccine for the first time, a second dose may be required to ensure full protection. This second dose is typically administered at least four weeks after the first. It’s important for parents to consult with their healthcare provider to determine the best timing for vaccination based on their child’s health history and the specific recommendations for that flu season.
