Tdap

The Faculty of Health Sciences Health Screening Policy follows the direction of the Ontario Hospitals Association and the Council of Ontario Faculties of Medicine.  Recently, both of these institutions have communicated to us that they require a single dose of Acellular Pertussis in health care providers younger than 65 years with direct patient contact. This in the form of a Tdap vaccine (ADACEL ) if not previously received as an adult or adolescent. There is no contraindication in receiving Tdap in situations where the student has had a recent Td immunization. This is supported by the Canadian Immunization Guide:

"NACI has concluded that there is no evidence of increased risk of severe adverse events for Canadian adolescents after receiving diphtheria and tetanus toxoid-containing vaccines at intervals of < 5 years. In the context of catch-up programs, given the vulnerability of this group to pertussis, the pertussis booster (Tdap) should not be delayed for fear of adverse events related to the diphtheria or tetanus toxoid component."
