The "5%" or "95%" number is from the Phase 3 trials and is the efficacy of the vaccine (Pfizer and Moderna have about the same number but the testing conditions were a bit different). The efficacy is the ratio of the number of positive cases from the test group and the number of positive cases from the control group and is statistically significant. This represents the reduction in the probability of you developing COVID if you are exposed and if you are fully vaccinated when compared to someone who wasn't vaccinated. This represents a 20x reduction in the probability. The breakthrough infections for the Phase 3 test group was about 0.02%; nowhere near 5%. The breakthrough percentage for the approximately 100M fully vaccinated is about 0.008%.
I guess I have misunderstood the 95% efficacy all along then? I am aware that real life efficiency of these mRNA vaccines is an 0.008% break through rate (thanks to GE who has posted this stat many times on this forum). Actually, that latest stat I have read for break through infection percentage is 0.009% as of about three days ago.
