Assuming your chance of getting COVID is "100", two weeks after vaccination your chance of getting it will have dropped to "3" and your chance of dying from it

Assuming your chance of getting COVID is "100", two weeks after vaccination your chance of getting it will have dropped to "3" and your chance of dying from it will be "0". Changes to your ability to have a symptomless infection and transmit it to others aren't entirely clear yet, but seem to tend towards the "3" as well. This is for the mRNA vaccines (Pfizer & Moderna). The others are potentially slightly less effective in preventing infection, but seem to be just about as good in preventing serious courses and death.
