MMR Vaccine – The MMR (Measles, Mumps, and Rubella Virus Vaccine Live) vaccine is very safe and most side effects are light and short-lived.
Because the MMR vaccine combines 3 separate vaccines in 1 injection, each vaccine can cause different side effects that can occur at different times.
There is less likelihood of side effects after the second dose of MMR than the first.
What is The Side Effect of MMR Vaccine?
Common side effects of MMR vaccine
About a week to 11 days after MMR injection, some children have a very mild form of measles.
This includes a rash, high temperature, loss of appetite and a general feeling of being sick for about 2 or 3 days.
Learn to treat a high temperature in a child
About 3 to 4 weeks after having MMR injection, 1 in 50 children develops a mild form of mumps.
This includes swelling of the glands on the cheek, neck, or jaw, and lasts a day or two.
One to three weeks after receiving the rubella vaccine component of the MMR vaccine, some adult women experience painful, hard or swollen joints, which may last for about 3 days.
Rare side effects of MMR vaccine
In rare cases, a child may have a small rash of bruises, such as stains about 2 weeks after the MMR vaccine.
This side effect is linked to rubella vaccine and is known as idiopathic thrombocytopenic purpura (ITP).
It has been estimated that ITP is developed in 1 in every 24,000 doses of the given MMR vaccine.
There is an increased risk of developing ITP from measles or rubella infection than the vaccine.
ITP usually looks better without treatment, but, as with any rash, you should seek advice from your doctor as soon as possible.
There is a small chance of having a seizure (adjustment) from 6 to 11 days after having the MMR vaccine.
It sounds alarming, but it is rare and occurs in just about 1 in every 1,000 doses.
In fact, MMR-related seizures are less common than seizures that occur as a direct result of a measles infection.
Allergic reaction to MMR vaccine
In extremely rare cases, a child may have a severe allergic reaction (medically known as anaphylaxis) immediately after the MMR vaccine.
It’s an alarming prospect, but if the child is treated quickly, they make a complete recovery. The medical personnel who give vaccines are trained to deal with allergic reactions.
Safety monitoring and side effects of MMR vaccine
The yellow card scheme allows you to report the suspicious side effects of any medication you are taking.
It is administered by a drug security vigilante called the Agency for the regulation of drugs and health Products (MHRA).
