Study shows dramatic decline in effectiveness of all three COVID-19 vaccines over time

As the Delta variant became the dominant strain of coronavirus across the United States, all three COVID-19 vaccines available to Americans lost some of their protective power, with vaccine efficacy among a large group of veterans dropping between 35% and 85%, according to a new study.

Researchers who scoured the records of nearly 800,000 U.S. veterans found that in early March, just as the Delta variant was gaining a toehold across American communities, the three vaccines were roughly equal in their ability to prevent infections.

But over the next six months, that changed dramatically.

By the end of September, Moderna’s two-dose COVID-19 vaccine, measured as 89% effective in March, was only 58% effective.

The effectiveness of shots made by Pfizer and BioNTech vaccine, which also employed two doses, fell from 87% to 45% in the same period.

And most strikingly, the protective power of Johnson & Johnson's single-dose vaccine plunged from 86% to just 13% over those six months.

The findings were published Thursday in the journal Science.

The three vaccines held up better in their ability to prevent COVID-19 deaths, but by July — as the Delta variant began to drive a three-month surge of infections and deaths — the shots' effectiveness on that score also revealed wide gaps.

Did I just misgender you? Tranny’s are so touchy!

Sorry, not sorry. 😎

If you can’t tell, it argues the second conclusion regarding your comment.

Not about misgender, more about a grown man? trying to act like a child.

Well now the story is, because it’s just like the flu shot you have to get it every year because it mutates and different variants come out every year. But originally they said get the shot so you don’t get COVID. They keep spinning different explanations.

"Not about misgender, more about a grown man? trying to act like a child."

What? No giggly, stupid emoticons like 😂🙂? Are you getting surely?

I would say that you're behaving menopausal but then I remember that trannies cannot go through menopause.😎

I can keep rhetorically flogging you like a dog and humiliating you until the end of time if you want to keep this up.

I meant “surly” and not “surely”. I was laughing too hard to check my spelling ;)

Thanks, I needed this.

[JonPreston]

You need what? I thought you needed sarc tags? And sure, continue as needed.😤

[WMarshal]

You have been PWND :).

[JonPreston]

Sorry, I don’t speak in code.

If the vaccines work, why aren’t they working?

If they didn't work how could their effectiveness decline over time?

[WMarshal]

"Sorry, I don’t speak in code."

Never broadcast ignorance.

pwnd

Tense of pwn.

An internet chat language variety/version of the word "owned", used in the sence of beating/defeating/outclassing someone. Usually used in games such as Counter-strike or on messageboards when a user posts arguments or insults that can't possibly be counter-argued.

Arguably considered so-called "l33t-speak"

"I pwnd you that round" "You just got pwnd dude" "I am going to pwn you like I did your mother last night"

[JonPreston]

So, you’re demanding sarc tags while talking like Beevis and Butthead? Please continue 🤪

My daughter age 42 is currently suffering from Covid and started last Saturday with flu symptoms slightly sore throat but 102’ fever for 4 days. Husband and 4 kids age 17,16,12,9 didn’t get it yet all are fine. Her wisdom is that hit harder than regular seasonal flu. She was tested and confirmed Covid.
