There are no special dietary contraindications to normal living and eating after MMR vaccination. According to the clinical experience of vaccination and relevant literature, there is no authoritative study to prove that MMR vaccine interacts with certain foods. The main effect of the vaccine occurs in the immune system and does not interact with the digestive system to produce side effects. After vaccination, you can eat normally without any contraindication. Vaccines prepare the body to fight infectious agents and can prevent certain serious or fatal infections. As a result of the vaccine, serious illness or death from infection is less common than in the past. After receiving the MMR vaccine, a reaction of pain and fever at the site of vaccination may occur, which is usually transient and can be relieved on its own. If the vaccinee continues to feel unwell, prompt hospitalization is recommended.
