Complete Guide to Baby Vaccinations 2025: Schedule, Side Effects & FAQs

2025 Vaccination Schedule

The CDC schedule includes: Birth (Hep B), 2 months (DTaP, IPV, Hib, PCV15, RV, Hep B), 4 months (DTaP, IPV, Hib, PCV15, RV), 6 months (DTaP, IPV, Hib, PCV15, RV, Hep B, Flu), 12 months (MMR, Varicella, Hep A, PCV15), 15-18 months (DTaP, Hib), 4-6 years (DTaP, IPV, MMR, Varicella). The RSV immunization (nirsevimab) is now recommended for all infants in their first RSV season.

Common Side Effects (and When to Worry)

Normal side effects: mild fever (up to 102°F), redness/swelling at injection site, fussiness, decreased appetite, and sleepiness for 1-3 days. These indicate the immune system is responding. Give acetaminophen (if approved by your doctor) for discomfort. Seek medical attention for: fever above 105°F, persistent crying for 3+ hours, seizure, severe allergic reaction (difficulty breathing, hives, swelling), or extreme listlessness.

Addressing Common Concerns

Vaccines do NOT cause autism — this has been definitively disproven by dozens of large studies involving millions of children. The original 1998 study was fraudulent and retracted. Vaccine ingredients (aluminum salts, formaldehyde traces, thimerosal) are in amounts far below what we encounter naturally in food, water, and the environment. The risk of disease far outweighs any vaccine side effects.

What If You're Behind Schedule?

It's never too late to catch up. If you've missed vaccines, your pediatrician can create an accelerated catch-up schedule. There's no need to restart a vaccine series if you've missed a dose — just pick up where you left off. Multiple vaccines at one visit are safe and tested extensively.

Frequently Asked Questions

Is this information medically reviewed?

Yes. All Wermom medical content is reviewed by board-certified pediatricians and OB-GYNs. We follow guidelines from the AAP, ACOG, WHO, and CDC. However, this information is educational and doesn't replace personal medical advice from your healthcare provider.

When should I call my doctor?

Trust your instincts. If something feels wrong or you're concerned about your baby's health, call your pediatrician. They'd rather hear from you with a question that turns out to be nothing than miss something important. For emergencies (difficulty breathing, unresponsiveness, seizures), call 911 immediately.
