BC backs up young adult vaccination rate on Vancouver’s coast

On September 23, the interactive panel of BCCDC showed that 99% of people ages 18 to 29 in the Vancouver Coastal Health Authority had received a first dose of the vaccine.

A number that has yet to reach any age group in any of the major healthcare regions of Canada and the United States.

When asked by CBC reporters about the accuracy of this data, the BCCDC He referred these questions to the Department of Health, who confirmed them.

The next day, while the graph retransmitted that the number of people who received a dose of vaccine reached 100% in this age group, the BCCDC added a note to the chart. He explained that college students from other parts of the province, but who were vaccinated in the Vancouver coastal region, artificially increased the percentage.

According to federal government data, as of September 18 in British Columbia, 83.1% of people between the ages of 18 and 29 had received at least one dose of the vaccine.

A review of provincial data as of Sept. 23 shows that the rate for 18-29 year olds who received a dose for the Vancouver Island Health Authority is 88% and that for the Fraser area is 90%.

Statistical anomaly

The 99% figure was first reported on Sept. 21 by a Vancouver Coastal Health Authority health physician, during a presentation on the pandemic to the University of British Columbia board of governors.

Daniel Coombs, a mathematician at the University of British Columbia who helped the province model the pandemic, was present at the meeting. He said the number immediately struck him as suspicious.

It was clear that something was wrong. It is so different from all other age groups., He explained.

There should be a second look at the numbers before they are released, simply because it doesn’t help the public perceive reliability when such claims exist.

Coombs explained that the inaccurate 99% figure ultimately had no serious consequences given the high vaccination rates at the Vancouver Coastal Health Authority.

Max Holmes, a student at the University of British Columbia who sits on the board of governors, agreed that the data error likely did not change the university’s strategy for containing transmission.

However, he trusts that this episode reinforces the concern for transparency, at a time when the university has just reinstated face-to-face classes.

The data is not available for people to review and analyze, he said. And if this turns out to be wrong, it creates a lot of frustration not just for policy makers, but for the community as a whole.
