Why MMR vaccine is given in subcutaneous site?

MMR is given SQ. Mmr should be given sq as that route gives the best antibody response and any deviation from that recommendation can result in inadequate protection. However, response to MMR vaccine probably will not be affected if administered by the im rather than sq route, and, therefore, repeating the dose is not necessary.
See below. During vaccine development, a lot of testing is performed. One of those is to determine the best site of the injection.
Rtecommended SubCuta. MMR Vaccine is Recommended by the manufacturer to be given subcutaneous but the efficacy is not adversily affected if given Intrmuscularly.
Good question. It appears that live attenuated virus vaccines such as MMR are given that way by convention but the intramuscular route works as well.

But it is !! Mmr if given in infancy and childhood will generally give a person lifelong immunity. In some cases, it does not and the vaccine can be repeated in adulthood.

Can you tell me one reason why the government still reccomends that all children are given the MMR vaccine.?

To avoid diseases. As long as there is international air travel and diseases that can be passed during incubation, we will need to vaccinate. Recent MMR outbreaks around Houston have been traced to imported cases (International Airport) that brought foreign cases into the area, that spread to unvaccinated or partially vaccinated kids. Measles can kill, so vaccines remain important. Read more...

My son is allergic to eggs. Can he be given the MMR vaccine?

No. The literature says it is ok..But .I would not recommend it. Once you inject something you cannot uninject it, nor can we guarantee he will have no reaction. Typically if someone anaphylaxes to egg, then the MMR is contraindicated. Mild reactions are not considered contraindication. If your instincts say no, then follow your instincts as well.

YES HE CAN BE. The vaccine contains chick cells and not the egg yolk or white in very severe cases of egg allergy you have to observe the child and keep adrenaline ready and facilities for intubation, but that kind of reaction is very rare.

How many doses of MMR vaccine is to be given to 18 year old adult? And what are its side effects in them?

Depends. The routine in the US is one dose at age 1 yr and again at 4-5.It is never repeated unless a prenatal workup shows a low protection level. If you never got it in childhood, it would be reasonable to do 2 doses at least a month apart to be sure adequate response was obtained. Some teens or adults note some transient joint pain during the weeks following the vaccine. Read more...
