Question
A 7-month-old baby vomited after receiving a vaccine, and the symptoms have persisted for several days. The parents are worried whether it is related to the vaccination or if there are other health issues. The baby has a decreased appetite and reduced milk intake, but the body temperature is normal.
Answer
Generally, it is normal for infants to have slight vomiting shortly after breastfeeding if they have a normal appetite, do not cry and fuss after vomiting, and do not have other symptoms. This may be a “regurgitation” phenomenon. However, if vomiting becomes more frequent, accompanied by projectile vomiting, and the amount of vomit increases, it may indicate congenital hypertrophic pyloric stenosis, which could lead to gradual weight loss in the baby. It is recommended that parents observe the baby’s symptoms and seek medical attention if necessary.
