Patient's question:
The child received the flu vaccine yesterday, and today they have a fever of 39 degrees. They are taking Tylenol to reduce the fever. Is it necessary to take any other medication?Doctor's answer:
This is an immune response caused by the vaccine. Generally, no other medication is needed.Most children do not have any reaction or only have very mild reactions after vaccination. A small portion of children may experience mild adverse reactions, some of which are normal, including local and systemic reactions.
Local reactions include redness, swelling, heat, pain, or enlarged lymph nodes at the injection site. Systemic reactions may include chills, fever, headache, reduced appetite, vomiting, or abdominal pain.
These conditions usually do not require treatment. Simply ensure the child drinks plenty of fluids and reduces activity. Within 1 to 2 days, these reactions will disappear.
