Question

My child received the hand, foot, and mouth vaccine this morning, and the third dose was administered at noon. They started vomiting after eating and even when drinking water. Is this normal?

Answer

For this situation, it’s advisable to take your baby to the hospital for a check-up. The baby’s vaccine reaction is unlikely to be severe, but since the baby is vomiting both when drinking water and eating, it’s considered gastrointestinal flu. It’s best to go to the hospital for a thorough examination and prevent dehydration.
