4 month vaccines side effects
The side effects of 4-month vaccinations, which typically include the second dose of DTaP (diphtheria, tetanus, and pertussis), IPV (polio), HepB (hepatitis B), Hib (Haemophilus influenzae type b), and PCV (pneumococcal conjugate vaccine), can vary from baby to baby.
However, common side effects may include:
- Pain, redness, or swelling at the injection site
- Fever
- Fussiness, irritability, or crying more than usual
- Loss of appetite
- Drowsiness or lethargy
- Vomiting
- Diarrhea
These side effects are usually mild and go away on their own within a few days. In rare cases, some babies may experience more serious reactions, such as a high fever, seizures, or an allergic reaction. If you notice any severe or persistent symptoms after your baby’s vaccinations, you should contact your healthcare provider immediately.
