    How do you determine effectiveness exactly? Did you ensure all subjects were exposed to the virus?

  9. The question now is: if Trump had won, would they have pulled out the vaccine anyway?

  10. (u$a vaccine) – Rather like Wolves offering to safeguard livestock!

  11. Side effects may include: Covid 19

  12. Shove it.

  13. Yeah I don’t trust 90% but thanks for coming out lol

  14. No human studies in 2 months at 90% .. trudeau goes first

  15. Long term effects unknown…so they want 2 more months to assess. When did 2 months become “long term”? No thank you.

    Unless you caught covid in the last few weeks. Than it’s useless.

    Because it’s a different strand, and you are now immune.

  17. operation warp speed

  18. It does not matter to me because I will not get the shot and will rely on my own immune system.

  19. can Canada get a refund if we’re not 100% satisfied?

    Don’t worry. Don’t be scared.
    If you’re scared don’t take the vaccine. Others will take it for you.
    You can wait. No need to poop on science. Don’t take the vaccine if you’re scared.
    You’ll be ok.
