  1. Uk medical journal for ba5 low hospitalization and death , take extra precautions on the elderly and END IT THERE!

    1. Just don’t take anymore and try and eat healthy. Hopefully you got one of the less dangerous batches and you can cleanse it out.

  2. 0.02 percentage points. That’s the difference in worst outcome (expiring from the virus) between having zero shots and three or more shots — 1.07% for those with 0 shots and 1.05% for those with 3+.

    That’s according to official data from the Public Health Agency of Canada.

    Based on that data, it seems the boosters are pretty much worthless in preventing the worst outcome of all.

    1. Interesting how you chose to leave out that same math for individuals with two doses. Wonder why that would be. Care to show the math for that group as well?

    2. Percentage of what? A percentage comparison is useless without stipulating the parameters of what was being measured. Either specify details of the comparison or, better yet, provide a link to the source so we can see what you were looking at for ourselves. I’m fairly confident you’re misinterpreting whatever you think you read. If the boosters are as useless as you claim then why is PHAC pushing them as the newest variant starts to take hold? It makes no sense for anyone who’s not a full blown conspiracy nut.

  3. Dr. Maria Shapiro must be unsuccessful as a doctor – that’s why she tries to make career as a TV expert.
