Question: 

Do people who only had one MMR dose (likely born between 1979 and 1995) need a second dose to protect against mumps?

Answer: 

The provincial mumps vaccine recommendations are outlined below. These recommendations may be different for select populations (for example, health care workers) and in outbreak situations.  There have been a small number of recently confirmed mumps cases in BC, however BC is not currently experiencing a mumps outbreak. 

Mumps vaccine recommendations:

One dose of mumps-containing vaccine (usually given as the MMR vaccine) is recommended for adults born in 1970 or later who do not have a history of mumps disease and laboratory confirmation of the same. The following groups need two doses:

  • children as per the routine schedule
  • students of post-secondary educational settings
  • travelers to outside of North America

People born before 1970 are generally assumed to have acquired immunity to mumps from natural infection. However, there may be susceptible people in this age group, and those who do not have a history of mumps disease or vaccine should talk to their health care provider about getting vaccinated.    

For measles protection, two doses of the MMR vaccine are recommended for people born in 1970 or later (who do not have laboratory evidence of measles immunity).

If you are unsure if your immunizations are up-to-date, we recommend that you contact your immunizing health care provider (public health nurse, physician or pharmacist). Your immunizing health care provider can review your immunization records and let you know if you are missing any vaccines. 

An important note about immunization records:

Without a record of immunization, or proof of immunity to a disease, a person is considered unimmunized and unprotected.  You can find tips on locating immunization records here

Vaccination is the best protection against mumps. For more information on the MMR vaccine, see the HealthLinkBC File: Measles, Mumps, Rubella (MMR) Vaccine.
