Question

After receiving the diphtheria, pertussis, and tetanus vaccine, there is a fever and back pain with crying. Is this a normal reaction? How should it be handled?

Answer

Common reactions that may occur after the diphtheria, pertussis, and tetanus vaccine administration include redness, swelling, pain at the injection site, fever, and crying throughout the body. These symptoms usually resolve on their own without special treatment. Less common reactions include mood instability, loss of appetite, vomiting, and fatigue. For severe fever reactions, symptomatic anti-inflammatory medication should be administered to avoid febrile seizures. Occasionally, regional masses may appear which can naturally resolve within 1-2 months; in rare cases, they may be accompanied by lymphangitis or lymphadenitis. In such cases, medical attention should be sought promptly.
