the real number we should be looking at is the absolute reduction rate which is less than 1%. Meaning we need to vaccinate over 100 people to reduce one case. Like the flu shot the vaccine barely does anything (other than disable & kill people). Theres a lengthy discussion here: link The 95% efficacy number has nothing to do with its effectiveness of reducing symptoms neither does it mean it will reduce 95% of the cases. It's a completely relative number that has no real world meaning other than to fool people into thinking its super effective.
