MMR stands for measles, mumps, and rubella. So basically, MMR vaccine is a sort of immunization vaccine which helps fight measles, mumps, and rubella. The vaccine is prepared by mixing the live attenuated viruses of all the 3 diseases. This vaccine is not administered orally but with an injection.
This vaccine was developed by Maurice Hilleman is sold by Serum Institute of India Tresivac. The first dosage of this vaccination is given in childhood around the age of a year and the second dosage is given at age of 4 or 5 years.
In the UK, the MMR vaccines are famous by the names of Priorix and MMRVaxPro, though the ingredients of both the vaccines are different. These vaccines contain active ingredients, sorbitol, recombinant human serum albumin, and polysorbate 80. There are traces of neomycin in both the vaccines. Neomycin is used to stop growth of the bacteria and it helps to save the vaccine from the contamination.
While there are MMR vaccines that may contain the gelatin derived from the pig, there are some that do not. To prepare the rubella strain for the MMR vaccines, human cell-lines are used. The strains for measles and mumps virus are grown on a culture. The culture essentially contains the chick embryo cells.
This vaccine is used around the world with an objective to bring down the number of cases of rubella, mumps, measles and congenital rubella syndrome. This vaccination dose is included in the plan of most of the Public Health Services around the world. Prevention of all of these diseases is the ultimate objective of this vaccination program.
Usually, 2 dosages of the MMR Vaccine are given throughout the world:
It is always advisable that if any child is traveling abroad between the ages of 6 to 11 months, he/she should be given MMR vaccine dose before the start of the journey. Actually, the reason is, the child may temporarily be protected from the measles if the dose is given beforehand. But remember, the dose given between 6 to 11 months do not give permanent immunity. For long-lasting protection, both the doses should be given again.
The requirement of third dose depends on the individual’s condition. Some adults might be susceptible to mumps, measles or rubella without even knowing about this fact. So if there is some mumps situation outbreak, the dose of MMR vaccine might be recommended by the doctor.
The side effects are not so serious, but we cannot altogether reject the idea of side effects. Let us discuss some of the side effects by categorizing them according to the frequency of their occurrence or the severity.
MMR Vaccine Common side effects (not so serious):
MMR Vaccine Rare and rarest side effects:
The vaccine triggers the immune system. This triggering of the immune system produces the antibodies against all of these three diseases. As the vaccine contains the weakened versions of the measles, mumps, and rubella, so as soon as a child comes in contact with any of these diseases, the immune system instantly identifies them and produces antibodies for fighting against them.
It is a well-known fact that the interactions with the drug may change the medication performance and cause some serious side effects. Some products which interact very badly with this vaccine are: drugs that make the immune system weak, corticosteroids, immune globulin etc. It also interacts with the chemotherapy drugs.
Interference with some laboratory test is also found. This produces some false positive test result. Before taking the drug, make sure that your doctor knows that you are using this drug.
There is no proper substitute for this vaccine. Some doctors and clinics administer injections for measles, rubella, and mumps separately. But the separate vaccines are found to be more risky. The time gap between the three dosages makes the children more vulnerable to the risk of mumps and measles. People often forget to bring their children for second and third vaccine shots. So this is quite risky.
Ans: Yes, 1 dose is about 93% effective and two doses are about 97% effective to prevent measles.
Ans: Yes, because the vaccine grows not on eggs but chick cells.
Ans: For more than 20 years to expect.
Ans: If you have vaccinated your child with the MMR vaccine at the proper dosage time, you will not require it to give them again for sure. But in the areas of the measles outbreak, the gap between the dosages can be reduced.
