Mumps vaccine is necessary for children. The mumps vaccine is intended for people over the age of 8 months who are susceptible to mumps. After mumps is cured, people are usually immune for life and rarely get infected again, so they do not need to be vaccinated again. Children before the age of 6 are at high risk for mumps, but some teenagers and adults may also be infected with mumps. Therefore, in addition to the need for mumps vaccination for children, adolescents and adults who are susceptible to mumps can also choose to be vaccinated, which can play a preventive role. Before receiving the mumps vaccine, it is important to know that you should not take any medication within 24 hours. If you have dizziness, headache, fever, or heat before vaccination, you need to postpone the vaccination. After vaccination, regular observation should be made. If there is any adverse reaction, it is recommended to seek medical advice as soon as possible.
