Yes. The immunisations/vaccines are not 100%. About 65% effective after 1st dose of mmr and 90% after 2nd.
It's not likely to get mumps after being immunized. However, you and your twin were likely immunized at the same time, and it's possible that whatever mechanism allowed him to get mumps in spite of immunization could also affect you. Ask your health care provider for advice specific to your situation.
It is a virus and it is contagious. Most people living in developed countries have been immunized against it (mumps is one of the "M's" in the MMR vaccine) so will have some resistance and probably will not get it even if exposed. While immunization makes catching it less likely it is still possible to get even if you have had the shots. If you have not been immunized or if you have a problem with your immune system then it is highly contagious.
Very contagious if you haven't been immunized.
the vaccination that most babies get is the MMR jab- measles, mumps and rubella
Everyone who has not been immunized.
An 85 year old is typically immune to mumps due to childhood exposure prior to widespread vaccination. There is no need to isolate a child recently immunized with MMR from elderly relatives.
Antibiotics are prescribed to treat bacterial infections. Mumps aren't caused by bacteria. Once someone has mumps, he/she is then naturally immune to it.
Mumps affect the parotid gland .
probably not - eye damage?
The vaccine has traditionally been given as an MMR (measles, mumps, ruebella) series in infants.
Only if you have never had the mumps, should you be worried.
Either can be given to a 3 year old. The anti tetanus serum should be given if there is reason to believe the child has not been immunized against tetanus before and has been exposed. If the child has been immunized, and there is reason to believe that they have been infected, the toxoid should be administered.
