Help CenterTdap is a combination vaccine that protects against three potentially life-threatening bacterial diseases: tetanus, diphtheria, and pertussis (whooping cough). Td is a booster vaccine for tetanus and diphtheria. It does not protect against pertussis.
Many states laws require colleges students to show proof of having received TDAP within the last 10 years or in some states multiple doses. It appears there is no history of this vaccination present in your account. If you have documentation of receiving a TDaP vaccination please upload it to your MedProctor account. If you do not you will need to receive a TDaP booster.
