Measles, Mumps and Rubella (MMR) and Vaccine Injury

What is the MMR Vaccine?

The MMR vaccine, also known by its trade name M-M-R II, is a single vaccine that protects against three diseases: Measles, Mumps, and Rubella.

The CDC recommends that MMR immunization occur in two rounds of vaccinations.

The first dose is typically administered between 12 and 15 months old, and the second shot is usually given between 4 and 6 years of age

Most children and adults who get the MMR vaccination have few or no side effects.  However, there are rare cases where the patient has a severe and debilitating reaction to the MMR shot. 

The federal government set up the Vaccine Injury Compensation Program (VICP)  to help people who experience severe injuries. A federal trust fund has paid out billions of dollars to compensate vaccine-injured patients across the country.

How Our Vaccine Injury Attorneys Can Help

Maglio Christopher & Toale Law Firm currently represents hundreds of vaccine injury patients across the United States.

The attorneys at mctlaw have won hundreds of millions of dollars in vaccine injury payouts and 100% of that money went directly to our clients. Our clients never pay a legal fee for our services, and we do not take any part of their financial award.

Not all attorneys are able to practice law before the Federal Vaccine Court. That’s why you should hire an attorney with extensive experience in this area of law. These are not simple personal injury cases. They are medically and scientifically complex.

Common Reactions to the MMR Vaccine

Acute Disseminated Encephalomyelitis

Acute Disseminated Encephalomyelitis, or ADEM, is a rare neurological disorder that primarily affects children but can also occur in adults. ADEM usually occurs after a viral or bacterial infection; however, there have been ADEM cases that developed following a flu shot.

With ADEM, the immune system essentially overreacts and produces inflammation in the nervous system and damages the protective layer that coats nerve fibers. This causes individuals with ADEM to experience confusion, blurry vision, and difficulty moving.

Though the disorder can be quite debilitating, the severity of symptoms can be managed with treatment, and individuals can make a full recovery from ADEM.


Encephalitis is inflammation of the brain. It can be caused by a direct infection to the brain (a condition called infectious encephalitis) or by the immune system mistakenly attacking the brain (a condition called autoimmune encephalitis, or post-infectious encephalitis). In very rare cases, individuals have experienced autoimmune encephalitis after receiving the influenza vaccine.

Although treatment for encephalitis exists, recovery from this disorder varies widely on a case-by-case basis. While some people make full recoveries, others are left with lifelong complications.

Transverse Myelitis

Transverse Myelitis is a rare neurological disorder in which both sides of the spinal cord become inflamed, causing paralysis, pain and other disturbances throughout the body.

An autoimmune disease, transverse myelitis occurs when a triggering event (such as an infection or even a flu vaccine) causes the immune system to go haywire and attack the spinal cord as if it were a disease.

The typical case of transverse myelitis causes weakness in an area of the body (such as the legs) that becomes progressively worse and can spread to other parts of the body.

Symptoms typically progress rapidly over the course of a few days. Recovery is either partial, moderate, or full depending on how well the individual responds to treatment.

Autoimmune Hepatitis

Autoimmune hepatitis is a condition in which the body’s immune system attacks the liver cells, causing liver damage and dysfunction. Though the cause of autoimmune hepatitis is not clear, in rare cases, autoimmune hepatitis has occurred in patients who recently received the flu shot.

Symptoms of autoimmune hepatitis include yellowing of the skin and eyes, abdominal pain, severe fatigue, and joint pain. Severe cases of autoimmune hepatitis may result in liver scarring (cirrhosis) and liver failure. The most serious cases require liver transplants for recovery.

Henoch-Schönlein Purpura

Henoch-Schönlein Purpura (HSP), also called IgA vasculitis, is a disease in which the blood vessels swell and can even leak. HSP occurs when the immune system becomes overactive and mistakenly attacks the blood vessels.

Though it is not clear what exactly triggers this overactive response from the immune system, some individuals have developed HSP after receiving the flu vaccine.

The primary symptom of HSP is a rash that resembles raised bruises or red dots. This rash, caused by leaking blood vessels, can spread throughout the entire body.

HSP can also cause digestive complications and, in the most serious cases, it can lead to kidney failure.

Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)

Chronic Inflammatory Demyelinating Polyneuropathy, or CIDP, is a disorder that causes weakness and dysfunction in the limbs. In rare cases, CIDP can develop after receiving a flu vaccine.

Though the exact cause of CIDP is not known, evidence suggests that it is an autoimmune disorder in which the immune system attacks the protective layer around the nerves.

CIDP typically begins with numbness or tingling in the toes and/or fingers, and then spreads to the arms and legs. Although some individuals experience permanent weakness in the affected body parts, most people with CIDP make a full recovery.

Polymyalgia Rheumatica

Polymyalgia Rheumatia (PMR) is a condition that causes widespread pain and stiffness throughout the body. The cause of PMR remains unknown, although some individuals (in very rare cases) develop PMR after receiving the MMR immunization.

Symptoms of PMR tend to be more pronounced in the morning. Fortunately, with proper treatment, stiffness and aching can be greatly reduced and even eliminated over time.

Thrombocytopenia Purpura

Thrombocytopenia is a disorder in which your blood platelet levels are lower than they should be.

Thrombocytopenia can be caused by a variety of factors, such as autoimmune disorders, pregnancy, medications, and–in very rare cases–the MMR vaccine.

Individuals with thrombocytopenia may have low blood platelet counts for one of three reasons: underproduction of platelets in the bone marrow (where all blood cells are produced), disproportionately large destruction of platelets, or platelets becoming trapped inside of the spleen.

Because platelets, also called thrombocytes, are necessary to clot the blood and stop bleeding, severe cases of thrombocytopenia can cause internal bleeding.

Symptoms of thrombocytopenia include excessive bleeding, patches of visible bleeding below the skin, bloody noses and gums, and fatigue.

Individuals may take years to recover. However, milder cases of thrombocytopenia can respond to treatment and resolve within a few days.

Are You Eligible to File a Vaccine Injury Claim?

There are some basic requirements to be eligible to file a claim in the Vaccine Injury Compensation Program:

  1. The vaccine must be one of the types listed on the Vaccine Injury Table by the VICP. 
  2. The claim must be filed within the statute of limitations. That means you have a short window of time to file a claim. 
  3. The vaccine injury must last for at least 6 months after the vaccination was given.
  4. Or, the reaction to the vaccination resulted in a hospital stay and surgery
  5. Or, the reaction must have resulted in death. 
  6. You must file a claim within a certain period of time.  There is a statute of limitations to file in the NVICP. It’s best to discuss this with an attorney to know when the clock on your case started ticking.
