Pfizer's vaccine is proving to be very effective as it's rolled out in the real world.
Data coming out of Israel found that the vaccine is 92% effective in preventing serious illness after people get both doses and 67% effective after one dose.
And even just a few weeks after the first dose, the vaccine was found to be 72% effective in preventing death.
Pfizer's vaccine is just as effective in younger adults as it is in the elderly.
