Why We Vaccinate

There’s a concerning trend emerging in Canada and the United States when it comes to vaccine hesitancy.

In the United States, a key legal adviser to Robert F. Kennedy Jr., the man tapped to be the next U.S. health secretary, is working to get rid of polio and hepatitis B vaccines in America, according to the New York Times. Kennedy himself has vocally opposed vaccines for years.

And here in Canada the overall childhood vaccination rate is declining, said Dr. Jason Wong, chief medical officer at the BC Centre for Disease Control. Wong is the deputy provincial health officer and a clinical associate professor in the University of British Columbia school of population and public health.

Dropping vaccination rates for children in Ontario raise measles fears

Just 70 per cent of seven year olds in Ontario were fully vaccinated against measles last year, according to Public Health Ontario.

That represents a steep drop in vaccination coverage compared to before the COVID-19 pandemic, according to the data. There have been similar declines for other routine childhood vaccines as well.

A decade ago, during the 2013-14 school year, 94 per cent of seven year olds in Ontario were fully immunized against measles. That number has steadily declined since then. Herd immunity for measles, which is among the most contagious infections in the world, is between 90 and 95 per cent.
