MMR-V Vaccine Supply Shortage

Please be advised that a supply shortage of ProQuad®, the combined Measles, Mumps, Rubella, and Varicella (MMR-V) vaccine, has recently been reported in Ontario. Additional doses are anticipated to be available from the Ministry of Health in mid-May.

During this shortage, individuals who require Measles, Mumps, Rubella (MMR) and Varicella vaccines can be offered the following products available through Hamilton Public Health:

• Priorix (MMR)
• Varilrix (Varicella)

In the absence of ProQuad®, we encourage you to offer Priorix and Varilrix to patients when appropriate.

Please note the following key points when administering Priorix (MMR) and Varilrix (Varicella) as separate vaccines:

• These vaccines may be administered during the same visit at different injection sites. If not given at the same visit, they should be spaced at least four weeks apart.
• Review the individual’s age and immunization history to ensure that MMR and/or Varicella vaccination is appropriate.
  • For further guidance, please consult the Ontario Routine Immunization Schedule:https://www.ontario.ca/page/ontarios-routine-immunization-schedule

If you have already placed an order for MMR-V, Hamilton Public Health will reach out to you directly. Hamilton Public Health will issue an updated communication once MMR-V orders can be resumed.

If you have any questions, please email Public Health at [email protected].
