  • Scheduling Vaccines

Can I give a tuberculin skin test (TST) on the same day as a dose of MMR vaccine?

Yes. A TST can be applied before or on the same day that MMR vaccine is given. However, if MMR vaccine is given on the previous day or earlier, the TST should be delayed for at least 28 days. Live measles vaccine given prior to the application of a TST can reduce the reactivity of the skin test because of mild suppression of the immune system.
