The tag on your account stating "TDaP Expired," means that your university requires a TDaP vaccine administered within 10 years. It appears that your most recent TDaP vaccination was administered more than 10 years ago. If you have documentation of an updated TDaP vaccination (administered within 10 years) please upload it. If you have not received this vaccine within the required timeframe of 10 years, you you will need to receive a TDaP booster.
