The top is so vaccines Pfizer and Moderna are 95% and 94% effective respectively. That means that there are still some people who will get sick even if they are vaccinated and some of those will die.

For sure, vaccinated people will get sick and die because the drug companies report “relative” risk rather than “absolute” risk ... very misleading. They do this all the time in their drug advertisements .... mathmatical jiu-jitsu.
Examining a statistic called absolute risk reduction — the number of percentage points that an individual’s risk goes down if they do something “protective” — the two companies’ COVID vaccines barely make a dent at all, reducing someone’s risk of experiencing COVID symptoms (the clinical trials’ endpoint) by less than 1%. This is the practical number that people are likely to care about most.
Knowing the paltry real-world impact of the injections on someone’s risk of developing COVID symptoms, how many people swayed by the misleading “95% effective” mantra might instead have decided to refuse the vaccines ....
In November — just before the FDA issued its initial Emergency Use Authorization (EUA) for Pfizer’s COVID vaccine — Doshi cautioned the public that Pfizer’s and Moderna’s efficacy results seemed dramatic only because the companies derived them from relative risk data.
Absolute risk, simply explained, is “the likelihood that an outcome will occur.” Relative risk “compares the risk of a health event … among one group with the risk among another group.”
Pfizer told the FDA that eight (of approximately 22,000) volunteers in its vaccine group developed a PCR-confirmed case of COVID-19, versus 162 of 22,000 volunteers in the placebo group. Moderna reported a similar spread — five out of 15,000 in the vaccine group versus 90 out of 15,000 in the placebo group.
When one does the math, the Pfizer clinical trial numbers showed: “The risk reduction in absolute terms [was] only 0.7%, from an already very low risk of 0.74% [in the placebo group] to a minimal risk of 0.04% [in the vaccine group].” (Dividing 0.7 — the difference between the two groups — by 0.74 is the mathematical calculation that produced the touted “95% effective” number).
Israel downgraded the vaccine to 65% effective
