The absolute risk reductions
for the current vaccines were tiny:
-- The relative risk reduction (RRR)
is best used for selling vaccines.
-- The absolute risk reduction (ARR)
is meaningful for the general public.
Data below are for non-severe COVID symptoms.
RRR and ARR are both calculated with the same numbers.
Vaccine.............RRR...........ARR
Pfizer...............95%......... 0.84%
Moderna...........94%..........1.25%
Gamaleya..........91%......... 0.93%
John. & John.....67%..........1.2%
AstraZeneca ......67%..........1.3%

"Severe Covid"........0.04%.......0.005%..........0.035%
