Blisters on your child’s body after MMR vaccination may be related to vaccine allergy or to diseases such as chickenpox or eczema.
Vaccines, as biological products, are mainly used for the prevention and treatment of appropriate diseases. The MMR vaccine, like other vaccines, may cause allergic reactions of varying degrees during use.
The most common adverse reactions after MMR vaccination are fever and rash, and due to individual differences, blisters and other allergic phenomena may also occur.
Chickenpox is a disease caused by the infection of varicella zoster virus, which is also characterized by blisters all over the body. Eczema is also characterized by a variety of clinical manifestations, such as macules, papules, blisters, vesicles, and so on.
For blisters that appear after your child has received the MMR vaccine, it is important to keep a close eye on them, and at the same time to have them promptly evaluated by a professional doctor and treated in a targeted manner.
