Please complete an updated Tdap/Td vaccine dose. Tdap/Td vaccines expire every 10 years. Completion of an additional Tdap/Td vaccine is required prior to the quarter your vaccine expires. There is no medical reason not to get an additional Tdap/Td dose before the 10 years has elapsed; you should be okay to complete it anytime.
If you have questions, please contact HSIP at myshots@uw.edu.
