Study finds Pfizer and Moderna vaccines may offer COVID protection for years, with one BIG caveat...

There is no place on earth where "lots of vaccinated people" are getting COVID.

https://www.cdc.gov/vaccines/covid-19/he...cases.html

Hospitalized or fatal vaccine breakthrough cases reported to CDC 4,115

CDC does not report on cases not hospitalized or fatal.

4,000+ hospitalized and at least 750 fatal breakthrough cases in the U.S. seems like lots to me. Each one is a human life that could have been saved.
4115/15,000,000 = 0.00027433 = 0.027433% chance of infection/hospitalization if fully vaccinated.

750/15,000,000 = 0.00005 = 0.005% chance of infection/death if fully vaccinated.

The math is in our favor. As Lemon Drop said, there are no absolute guarantees.

The people who should be worried are those who insist on remaining unvaccinated.

Breakthrough infections leading to hospitalization and death, which are very rare, are primarily in seniors, not parents of school aged kids. It is the unvaccinated parents at high risk, not the vaccinated ones. While we wait for vaccine approval for kids under 12, we need parents to get immunized to keep themselves and their children safe.

Wear a mask.
Get vaccinated.

I've never stopped wearing a mask in stores.
This is a situation in which a belt AND suspenders are warranted.
On top of a mask? Damn, this COVID thing is a pain in the ass!

Another article I read on this pointed out that you have to look at not at what percentage of those infected with Delta have the full vaccination, but also at what the total number of people fully vaccinated is, and compare that with the number infected--that shows the breadth of the protection.

The only way to evaluate the effectiveness of the vaccine against the Delta variant is to test for exposure to the Delta variant and look at the number of breakthroughs in that context.

Since we seldom test for exposure and almost never test for specific variants in this country, we need to look to other countries for guidance.

This is what you get when you do that:

In general, Covid jabs are most effective against the most severe outcomes, such as death, and less effective against less severe ones, such as asymptomatic infection.

According to figures gathered by Public Health Scotland and published in the Lancet, at least two weeks after the second dose of Covid jabs, protection against infection fell from 92% for the Alpha variant to 79% against the Delta variant for the Pfizer/BioNTech vaccine, while for the Oxford/AstraZeneca vaccine the protection fell from 73% to 60% respectively.

...According to an analysis by PHE, the Pfizer/BioNTech jab was linked to a 94% vaccine effectiveness against hospital admission with the Delta variant after one dose and 96% after two doses, while the figures for the Oxford/AstraZeneca jab were 71% and 92% respectively.

This protection against hospital admission is similar to that for the Alpha variant, for which the Pfizer figures were 83% and 95% after the first and second jabs respectively, and 76% and 86% respectively for the AstraZeneca jab.

If we assume that the J&J offers similar protection as AZ (big "if" but we have almost no public info on J&J's efficacy) then we're looking at maybe 60% effectiveness at preventing infection and 71% against hospital admission once infected.

It should be noted that the FDA has a hard cutoff of 50% effectiveness in their guidance for approval of "safe and effective" COVID vaccines.
