The measles virus causes a fever, rash that starts on the face and spreads to the rest of the body, cough, red eyes and a runny nose. Measles complications include ear infections, pneumonia, miscarriage, encephalitis (swelling of the brain), brain damage and death. Measles virus is easily spread through the air, by droplets from coughing, sneezing and talking and through direct contact with an infected person.
The mumps virus causes a fever, headache and salivary gland swelling in the cheeks and jaw (parotitis). Complications include meningitis (inflammation of the lining that covers the brain and spinal cord), painful swelling of the testicles or the ovaries, deafness and miscarriage. It is spread by contact with the saliva of an infected person (e.g. sharing drinks, food or kissing) or by droplets from coughing, sneezing and talking.
The rubella virus causes a fever, sore throat, swollen lymph glands in the neck and a rash on the face and neck. The symptoms can be absent or mild in children. Adults may have a headache, weakness, runny nose, red eyes and, rarely, swelling of the joints. Rubella can also cause encephalitis (swelling of the brain). Rubella is most dangerous in early pregnancy when it can cause miscarriage, stillbirth or severe birth defects such as cataracts, deafness, heart defects, and intellectual and developmental disability known as congenital rubella syndrome. Rubella is spread by droplets from coughing, sneezing and talking and from contact with the throat and nasal secretions of an infected person.
Chickenpox is a common childhood illness caused by varicella zoster virus. Chickenpox is very contagious. Symptoms include fever, headache, fatigue and an itchy rash. The rash begins as raised pink or red bumps and can spread to almost anywhere on the body. The bumps will gradually form into blisters and then scab over.
The virus is spread by airborne droplets and by direct contact with the blisters. Healthy children tend to have milder symptoms. In rare cases, chickenpox can cause severe complications such as pneumonia, blood infections, severe skin infections, encephalitis (swelling of the brain), birth defects and death.
Once a person has had chickenpox disease, if it was more than a mild case and over the age of one, they are usually protected for life. In adulthood, the virus can reactivate causing a painful rash called shingles.
MMRV is usually given between 4 and 6 years of age as the second dose of vaccine for these four diseases. Children 4 to 12 years of age who are susceptible to these diseases should also receive this vaccine. MMRV protects almost all children against these four diseases when it is given as the second dose of vaccine.
Common side effects include redness, soreness and swelling where the needle was given. Fever is less common and sometimes, a mild chickenpox, measles or rubella-like rash can occur. If a chickenpox like rash develops, it should be kept covered and will get better on its own. In this case it is important to avoid susceptible persons who may be at high risk for severe disease, including pregnant women, newborns, patients in hospital or out-patient settings, and persons who are immunocompromised (including transplant recipients or HIV infection).
Severe allergic and other reactions are very rare. Signs of severe allergy include hives, swelling of the mouth and throat, wheezing, chest tightness, difficulty breathing, difficulty swallowing, hypotension and shock.
There have been studies that showed a possible increased risk of febrile seizures in children who received the MMRV vaccine as a first dose when younger than two years of age. In Ontario, the vaccine is not given to children under the age of four. Children who are four to six years of age do not experience febrile seizures as often as children less than four years of age.
You should report any side effects or severe vaccine reactions to your health care provider.
After you receive an immunization, make sure your healthcare provider updates your personal immunization record such as the "Yellow Card". Keep it in a safe place. If your child is 17 years of age or under and receives this vaccine please report this information to KFL&A Public Health online or by calling 613-549-1232. Health care providers do not automatically send immunization information to KFL&A Public Health. It is the responsibility of parents or guardians to provide this information.
