1/ A few points to clarify a few points...
These vaccines are really really good, but not perfect.
One dose of a vaccine provides excellent protection against #COVID19 infection, but of course 2 doses provide more protection. https://twitter.com/drmwarner/status/1387420736202149889

2/ NACI outlines protection after 1 dose of a vaccine in their recent document:
"Most importantly, these studies show one dose of the Pfizer-BioNTech & AstraZeneca vaccines are
approximately 80% effective against hospitalization..."

3/ Here is some of the data backing up NACI's statement above, but from a clinical trial.
This graph below is with Pfizer...look at how people start to gain protection ~12-14 days after their 1st dose (red line).
Pretty impressive.

4/ But going back to the 1st point, while 1 dose provides pretty decent protection from #COVID19, 2 doses are ideal.
Stretching out the interval between dose 1 & 2 i(in Canada) provides protection to more people over a shorter period of time.
This will end our pandemic faster.

So can you get #COVID19 even 2 weeks after your 1st dose?
Of course - but your risk is much lower.
Can you get really sick?
Sure - but your risk is also much lower.

6. So what do we do?
The same thing we've been doing all along...mask indoors, avoid close, confined, crowded settings. Ventilate rooms. Spend time outdoors. You know...the usual.
Also, we'll probably get 2nd doses before 4 month due to
supply. (Probably).

7. Also, while these vaccines are really really good, they are not perfect. People can still get sick even after 2 doses.
It's pretty uncommon, but it can happen.
The CDC discusses it here: https://bit.ly/2S2JWSK

8. With time, vaccines will help us return to normalcy.
Take home points:
-Vaccines work really really well
-2 doses better than 1, but 1 still really good
-Maintain precautions after 1 dose, you are not invincible
We'll get through this.
