What every parent should know about vaccines

When it comes to vaccinating children, even a minor illness can leave parents uncertain. Here’s what health experts have to say about staying on schedule.
It’s a common worry among parents: Should you delay your child’s vaccinations if they’re feeling under the weather? Health experts, including the CDC and leading medical organizations, confirm that mild illnesses such as a low-grade fever, cold, runny nose, cough, ear infection, or mild diarrhea typically do not interfere with vaccines.
In fact, children with mild conditions can safely receive their scheduled immunizations without any impact on the effectiveness of the vaccine or worsening of their symptoms. Doctors also emphasize that delaying vaccines offers no health benefit and could leave children vulnerable to preventable diseases.
Vaccines are designed to work even when the immune system is handling minor illnesses. Moreover, antibiotics prescribed for mild conditions do not affect a child’s response to vaccines, so there’s no need to postpone their shots.
However, if your child is experiencing a moderate or severe illness—such as high fever or a chronic health condition like cancer—it’s essential to consult with a healthcare provider. In such cases, they might recommend rescheduling some vaccines to ensure your child’s comfort and safety.
Staying on track with vaccinations protects your child and others from serious diseases. Talk to your pediatrician if you have concerns about your child’s health before their vaccine appointment.
