Baby Vaccinations Side Effects

Vaccinations are given to babies to protect them against disease and illness. The Centers for for Disease Control and Prevention has developed a schedule for when a child should receive his immunizations. The vaccination schedule begins at birth and continues throughout adulthood. Although some vaccinations carry the risk of certain side effects, the benefits of vaccinations far outweigh the risks, reports the March of Dimes. Parents should be aware of and understand how to manage side effects.

Injection Site Complications

A common side effect of vaccinations is injection site complications. Redness, swelling and tenderness may occur at the site of vaccination, reports the Centers for Disease Control and Prevention (CDC). You may notice a hard lump where the shot was given. These side effects should only last for a couple of days following vaccination. A cool compress may be used to diminish swelling. Use caution while lifting and handling your child. Avoid placing additional pressure on the affected area.

Fever and Irritability

Your baby may develop a low-grade fever following vaccination. Ask your physician if you could use an age appropriate dose of infant strength acetaminophen (Tylenol) to relieve your child's fever. Irritability is common following vaccination. Your baby may seem upset and more difficult to soothe 1. Some physicians will recommend infant acetaminophen to relieve irritability. If your baby develops a fever that does not respond to medication, contact your healthcare provider immediately.

Poor Feeding

You may notice that your baby is not eating as well following vaccination. This is a common side effect of vaccines. Encourage formula or breast milk multiple times throughout the day to avoid dehydration in your baby. If your child is older, an electrolyte solution is an effective way to keep your child hydrated. Your baby's appetite should return to normal after a couple of days 1. If your child refuses to eat, seek immediate medical attention.
