Minor side effects after immunizations are quite common, but they are usually temporary.
Your child may get inflammation and puffiness at the site of the vaccination injection. A little rash, particularly after the MMR injection, is common. You can effectively relieve these side effects by giving your children the advisable dose of ibuprofen and paracetamol, before or after the injection.
Severe side effects right after vaccination are uncommon, but seek medical advice if your children have any of the following symptoms after immunization:
- A fit (convulsion);
- Continuous fever more than 39.5°C;
- Extreme physical reaction, such as painful and continual swelling, at the injection site;
- Loss of consciousness, breathing difficulties or large welts on the skin, which can be ordinary symptoms of a relatively uncommon allergic reaction known as anaphylaxis. If you think your child is having anaphylaxis, take him to the nearest hospital immediately.
Severe side effects are uncommon, but they can happen. Be mindful that all the immunizations offered the doctor are far less likely to bring complications than getting the disease. For example, encephalitis or meningitis affects less than one in a million babies receiving the MMR vaccination, but 1 in 300-400 babies who contract mumps.
Seek advice from the health advisor or doctor before immunization if your child:
- Has an intense illnesses followed by fever. Your doctor is likely to suggest you to delay vaccination until the unexpected illnesses have subsided. (This doesn’t include earaches, colds, and mild coughs.)
- Has had an unexpected reaction to a previous immunization. This significantly elevates the chance of an adverse reaction to later similar immunizations.
- Has an eggs allergy (the MMR vaccine is made in eggs. While the quantity of egg contained within the vaccine is really small that it likely will not cause a serious problem even if your children has a serious allergy, your doctor may recommend that your children has the vaccination performed under close supervision).
- Has ever had a fit (convulsion).
- Has any medical problem that affects his immune system, for example AIDS or HIV. (A child whose immune mechanism is not working adequately should not get live vaccines.)
- Is taking any drugs that influence her immune mechanism, for example, immunosuppressant after organ transplant or chemotherapy.
