As long as your child is eligible to get the flu shot and COVID-19 vaccine, then it is safe to administer them together.
The best way to protect you and your family against influenza (flu) is by getting the flu shot every year.
Even if children have already had COVID-19, they should still receive the vaccine once they have recovered from the illness.
The Centers for Disease Control and Prevention, the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine all recommend pregnant people get vaccinated against COVID-19.
While your child’s original vaccine continues to protect them against severe illness and death, it will wear off a bit over time. A booster shot provides extra protection against COVID-19.
