FAQ: Vaccines for Children

The CDC recommends vaccines at specific ages to protect children when they're most vulnerable:

• Birth: HepB (1st dose)
• 2 months: DTaP, Hib, IPV, PCV13, Rotavirus (1st doses)
• 4 months: DTaP, Hib, IPV, PCV13, Rotavirus (2nd doses)
• 6 months: DTaP, Hib, IPV, PCV13, Rotavirus, COVID-19 (3rd doses)
• 12-15 months: MMR, Varicella, HepA, PCV13 (4th dose)
• 4-6 years: DTaP, IPV, MMR, Varicella (boosters)

Yes. Children's immune systems can handle many vaccines simultaneously. Studies show no increased risk of adverse events from multiple vaccines.

A baby's immune system encounters thousands of antigens daily from everyday activities. The total antigens in all vaccines combined is a tiny fraction of this.

Vaccine ingredients are carefully evaluated for safety:

• Aluminum salts: Used as adjuvants; safe in small amounts (less than 1mg per dose)
• Gelatin: Stabilizer; used in some vaccines; those with severe allergies can receive gelatin-free alternatives
• Egg proteins: Found in some flu and MMR vaccines; egg-free alternatives available
• Thimerosal: Removed from all childhood vaccines except multi-dose flu vials

Most side effects are mild and temporary:

• Apply a cool, wet cloth to reduce soreness
• Use infant acetaminophen for fever (consult your pediatrician for correct dosage)
• Offer extra fluids and comfort
• Keep the vaccination area uncovered

Call your doctor if your child has a fever over 104°F, seizures, or unusual fussiness lasting more than 24 hours.
