PHO Grand Rounds: Effectiveness of Pertussis Vaccination and Duration of Immunity
Tuesday, December 6, 2016 12:00 pm to 01:00 pm
Venue: By webinar only
Research and Collaboration; Learning and development; Infectious Diseases
City: Toronto
Type: PHO Grand Rounds
Format: Webinar

Note: This is an open invitation, and may be forwarded to interested parties.

Outbreaks of pertussis, or whooping cough, have emerged globally and within Ontario. Evidence suggests the acellular pertussis vaccine immunity wanes over time. This session will discuss results from a recently published PHO/ICES study evaluating pertussis vaccine effectiveness in Ontario, including waning of immunity and whole cell vaccine priming.  The discussion will focus on the potential public health responses to improve control of pertussis in Canada.    ​

Presenter: Dr. Kevin Schwartz

Dr. Schwartz is a paediatrician and infectious disease consultant in Toronto. He has recently joined PHO as an IPAC and antimicrobial stewardship physician.
