There was a back in 2009 about problems with the previous year’s seasonal flu shot in Canada.
British Columbia will join four other provinces and delay part of its seasonal flu shot program this year until after the swine flu shots have been rolled out.
Perry Kendall, the province's chief medical officer of health, says the decision is in part due to concerns raised by an unpublished study suggesting people who got a seasonal shot last year were more likely to catch swine flu this year.
The problem seemed to be that these vaccines over trained your immune system on one strain, or even a set of strains. Then it would not respond properly to other strains or viruses. It was clear they did not quite know what they were doing with these seasonal vaccines.
I was not surprised when we started seeing the same thing with the COVID-19 vaccines.
