The numbers frequently cited don't communicate how infectious and deadly this virus is.
For instance, less than 10% of the world population has contracted COVID, so we could falsely say there's a greater than a 90% chance you won't get COVID. The numbers are similar in the states, as less than .002% of the population has died from COVID, 99.983% have survived. We all know those numbers ignore exposure. Those numbers would be much greater if everyone was exposed. This goes the same for the 125,000 breakthrough cases. It's misleading to say 99.99% of vaccinated people won't catch COVID because of the relatively small number of breakthrough cases at this point. Again, it ignores exposure, and I can attest that after my wife and brother contracted COVID after being fully vaccinated, the symptoms are much worse than some would like to believe.
Not sure where we are headed with seemingly never ending and worsening mutations, but I'm fully vaccinated and didn't contract it from my wife, so the vaccine is working at least a little bit. An Israeli study showed Pfizer at about 66% efficacy against infection. I think that's about right, as my brother contracted the virus at a conference where about a 1/3 got infected and everyone was vaccinated. No one died, one was hospitalized, and I know of one other who said he felt like he was going to die.
