How often should a child get a booster shot?

Children typically receive booster shots according to a vaccination schedule set by health authorities, such as the CDC in the United States. Generally, booster shots for vaccines like DTaP (diphtheria, tetanus, and pertussis) are given at ages 4-6 and then again around 11-12 years. Other vaccines may have different schedules, so it's important for parents to consult with their pediatrician to ensure their child is up-to-date on all vaccinations. Regular check-ups can help keep track of booster shot needs.
