The MMR vaccine is very safe for your baby.
Nevertheless, some infants may experience modest to significant side effects from the MMR vaccination.
Fever and a slight rash are two of the most frequent minor side effects.
Joint pain and stiffness, seizures, and low platelet count—all of which are uncommon—are considered moderate adverse effects.
The more severe side effects, which are incredibly rare, include allergic reactions like hives, swelling, and breathing difficulties.
If your infant exhibits any of these side effects, speak with your doctor right away.
