Sometimes, children are in poor physical condition and are not suitable for vaccination, and the vaccination needs to be postponed. If parents do not follow the doctor's advice and insist on vaccination, adverse reactions are likely to occur, especially the MMR vaccine, which must be injected under the guidance of a doctor. So, what are the possible reactions to the MMR vaccine? Let's take a look at the detailed introduction below.

MMR vaccine

Generally speaking, before injecting the vaccine, the doctor will check the child's physical condition. If the child is in poor physical condition, has a cold or suffers from certain diseases, it is not suitable for vaccination. In other words, vaccines are not suitable for everyone, especially the MMR vaccine, which has very high requirements and may cause a larger reaction after injection. So, what are the possible reactions to the MMR vaccine? Let’s take a look at the detailed introduction below.

Some adults may experience transient joint pain 2-4 weeks after vaccination, which generally does not require special treatment. Symptomatic treatment can be used if necessary.
