Am I at a great risk of infection after my first dose but before my second dose of the vaccine?

No! In fact, what is really great is that the Pfizer vaccine has been shown to cause a 52% efficacy with the first dose alone — and within 10 days of the dose! That is really incredible!

Still — you do not get that 90+% efficacy until you get the second dose; so please make sure to follow-up with your second dose; and always wear a mask, maintain social distancing and wash your hands!
