UW HSIP- Rejected MMR Negative Titer(s)

1 min. readlast update: 03.13.2025

One of your MMR (Measles, Mumps, and Rubella) titer components was negative, low, or equivocal, indicating you do not have immunity. Please proceed with starting the 2-dose MMR vaccine series as soon as possible.  

Please complete an MMR vaccine dose as soon as possible and submit the documentation for approval. Once approved, a Subsequent MMR Dose #2 tag will be created for your second dose which will need to be administered at least 28 days from your first dose. 

Note: Live vaccines (MMR and Varicella) can interfere with TB screening results, so HSIP recommends completing your TB screening prior to any live vaccines OR completing your TB screening at least 28 days after a live vaccine. 

If you have questions, please contact HSIP at myshots@uw.edu.
