Looking at the extremely early numbers that we have so far...the vaccines are pretty much worthless.
Pfizer says its vaccine is 95% effective. (It's really 0.75% effective...yes, that's ZERO POINT SEVEN FIVE PERCENT...less than 1%)
Moderna says its vaccine is 94.5% effective. (It's really 0.57% effective.)
AstraZeneca says its vaccine is between 62% - 90% effective (It's really 0.47% effective.)
All of the companies are using the marketing technique of RRR (relative risk reduction) when ARR (absolute risk reduction) is a better way to measure how effective they are. Please understand that this is based solely on the very limited data which has been released to the public at this point. These numbers are subject to change.
Another helpful metric to consider is NNV (number needed to vaccinate). The NNV is how many people need to receive the vaccination in order to protect ONE PERSON. The ideal NNV is 1, which means that every person vaccinated gets protected. However, a perfect vaccine such as that has never been made. An NNV of 2 means that for every 2 people vaccinated, 1 of them is protected and the other is not (a 50/50 shot...npi). The best vaccines usually fall in between 1 and 2.
Pfizer/BioNTech NNV = 133
Moderna NNV = 175
AstraZeneca = 213
Pathetic. And for those who have already been infected and have the more robust natural immunity, why would they want to be vaccinated with whatever negative side effects might be associated with these new mRNA vaccines?
