The MMR vaccine is an injection that helps prevent measles, mumps, and rubella. Like all medicines, it can cause side effects, but not everyone will experience them. The most common adverse events following the MMR vaccine are pain at the site of injection, fever, mild rash, and swollen glands in the cheeks or neck. More rarely, the MMR vaccine can cause a temporary low platelet count, which can lead to unusual bleeding or bruising. In people with serious immune system problems, the vaccine may cause a life-threatening infection.

What You'll Learn
Swelling in the neck is a common side effect
The most common adverse events following the MMR vaccine are pain at the injection site, fever, a mild rash, and swollen glands in the cheeks or neck. This swelling in the neck is typically a result of the vaccine causing swollen lymph glands. This is a normal immune response and usually goes away within a few days. It is important to note that the side effects of the MMR vaccine are usually mild and will pass quickly.
In addition to the physical side effects, some people may experience a temporary low platelet count, which can lead to unusual bleeding or bruising. This is a rare occurrence and is not life-threatening. However, it is always recommended to consult a healthcare professional if any side effects are concerning or persist.
While serious allergic reactions to the MMR vaccine are extremely rare, they can be life-threatening. Symptoms of a severe allergic reaction may include hives, swelling of the face and throat, difficulty breathing, a fast heartbeat, dizziness, and weakness. Anyone who has ever had a life-threatening allergic reaction to any component of the MMR vaccine should not receive the vaccine.
Overall, the MMR vaccine is considered safe and effective, and the benefits of protection against measles, mumps, and rubella outweigh the risks of potential side effects.

Other side effects include fever and rash
The MMR vaccine is generally considered safe, and most people do not experience any serious side effects. However, as with any medicine, side effects can occur. The most common adverse events following the MMR vaccine include pain at the injection site, fever, mild rash, and swollen glands in the cheeks or neck.
Fever is a typical reaction to any vaccination and is usually mild. In babies, a dose of infant paracetamol can be administered if the fever causes discomfort. For children under 16, it is important to avoid medicines that contain aspirin.
The rash that may develop after the MMR vaccine is typically mild and raised, similar to a measles rash. It usually appears 7 to 11 days after vaccination and resolves quickly.
Swelling in the cheeks or neck region may also occur as a side effect of the MMR vaccine. This swelling is often associated with the development of swollen glands, which can be felt around the cheeks, neck, and jaw. This side effect typically arises around 2 to 3 weeks after vaccination.
While neck lumps have not been specifically mentioned as a side effect of the MMR vaccine in the sources provided, swelling in the neck region and swollen glands in the neck are recognised side effects. Therefore, it is possible that neck lumps could be indirectly related to the MMR vaccine in rare cases.

Severe allergic reactions are rare
The MMR vaccine is a live vaccine that protects against measles, mumps, and rubella. It is recommended for all babies and young children, but older children and adults can also receive it if they were not vaccinated when they were younger. The vaccine is generally considered safe, and most people who receive it do not experience any serious problems.
However, as with any medicine, there is a small risk of side effects. The most common adverse reactions following the MMR vaccine include pain at the injection site, fever, mild rash, and swollen glands in the cheeks or neck. While rare, some individuals may experience a temporary low platelet count, which can lead to a non-life-threatening bleeding disorder.
Severe allergic reactions to the MMR vaccine are extremely rare but can be life-threatening. People who have previously experienced life-threatening allergic reactions to any component of the MMR vaccine, such as neomycin or gelatin, should not receive the vaccine. Symptoms of a severe allergic reaction may include hives, swelling of the face and throat, difficulty breathing, a fast heartbeat, dizziness, and weakness.
It is important to note that the benefits of the MMR vaccine typically outweigh the risks. The vaccine provides long-term protection against measles, mumps, and rubella, which are highly infectious diseases that can lead to serious complications, including meningitis, blindness, hearing loss, and, in the case of measles, even death. Furthermore, receiving the MMR vaccine helps protect vulnerable individuals who cannot be vaccinated, such as newborns and those with weakened immune systems.

Temporary low platelet count may cause bleeding
The MMR vaccine is a combination vaccine that protects against measles, mumps, and rubella. These are highly infectious diseases that can cause serious medical complications. The vaccine is generally considered safe, and most people do not experience any serious problems after receiving it.
One rare side effect of the MMR vaccine is a temporary low platelet count, which can lead to a bleeding disorder. This side effect is uncommon and usually resolves without treatment. A low platelet count can cause bleeding or bruising and may present as petechiae (small red or purple spots on the skin). In most cases, immune thrombocytopenia (ITP) following the MMR vaccine is mild. Severe bleeding requiring hospitalisation and/or transfusion is rare.
The MMR vaccine has been linked to a small increased risk of febrile seizures, particularly in children younger than seven years old. This risk is estimated at one in 3,000 to 4,000 children vaccinated. However, these seizures are not associated with any long-term effects.
Other common side effects of the MMR vaccine include pain at the injection site, fever, a mild rash, and swollen glands in the cheeks or neck. These side effects are typically mild and self-limiting.
While rare, severe allergic reactions to the MMR vaccine can occur and can be life-threatening. Anyone who has had a life-threatening allergic reaction to the antibiotic neomycin or any other component of the MMR vaccine should not receive the vaccine.
It is important to weigh the risks and benefits of any vaccine, and the MMR vaccine has been shown to provide significant protection against measles, mumps, and rubella. The CDC and FDA continuously monitor vaccine safety and are committed to ensuring that vaccines provided to the public are safe and effective.

Report side effects to your healthcare provider
The MMR vaccine is a shot that can protect you and your child from getting measles, mumps, and rubella. It is a combination of three vaccines in one shot. These three infections spread easily between people and can lead to serious problems, including meningitis, blindness, and hearing loss.
Like all medicines, the MMR vaccine can cause side effects, but not everyone will experience them. The most common adverse events following the MMR vaccine are pain where the vaccine is given, fever, a mild rash, and swollen glands in the cheeks or neck. These side effects are usually mild and only last 2 to 3 days.
More serious side effects, such as a severe allergic reaction (anaphylaxis), are rare. However, if you experience any concerning side effects after receiving the MMR vaccine, it is important to report them to your healthcare provider. Healthcare providers and vaccine manufacturers are required by law to report certain adverse events following vaccination to the Vaccine Adverse Event Reporting System (VAERS). You can also submit a report to VAERS directly or contact your healthcare provider for advice.
In addition to reporting side effects to VAERS, you can also call your doctor for medical advice. You may also report side effects to the FDA at 1-800-FDA-1088. It is always better to seek medical advice if you are unsure about any side effects or health problems after receiving the MMR vaccine.
