Effectiveness of 2 of 3 COVID-19 Vaccines Used in US Drops Below 50 Percent After 6 Months: Study

The effectiveness of the three COVID-19 vaccines available in the United States has declined in recent months, with protection against infection falling under 50 percent for two of them after six months, according to a new study.

Moderna’s COVID-19 vaccine dropped to 58 percent in September from 89.2 percent effectiveness in March, researchers found. During the same time frame, Pfizer’s COVID-19 vaccine fell to 43.3 percent from 86.9 percent, and Johnson & Johnson’s shot declined to 13.1 percent from 86.4 percent.

Dr. Stephen Hahn, head of the Food and Drug Administration during the final portion of the Trump administration, said last year that the agency wouldn’t authorize COVID-19 vaccines that weren’t at least 50 percent effective against infection.

The researchers also found that the vaccines’ protection against death waned after six months, particularly among older people. Instead of comparing the effectiveness in March and September, though, they used the data to pinpoint the effectiveness from July to October. For those 65 or older, the effectiveness against death was 75.5 percent for Moderna’s vaccine, 70.1 percent effective for Pfizer’s vaccine, and 52.2 percent effective for Johnson & Johnson’s jab.

For younger people, the effectiveness was higher: 84.3 percent for the Pfizer vaccine, 81.5 percent for Moderna, and 73 percent for Johnson & Johnson.

While early data showed high vaccine effectiveness against both infection and death, “our results suggest vaccines are less effective in preventing infection associated with the Delta variant,” researchers wrote.

While the vaccinated over time faced a higher risk of getting infected with COVID-19 or dying, the unvaccinated were still more likely to contract the illness or die from it, they said.

Researchers with the Public Health Institute, the University of Texas School of Public Health, and the Veterans Affairs Medical Center carried out the research, which was published in the journal Science.

Researchers examined COVID-19 infections and deaths by vaccination status in 780,225 veterans between Feb. 1 and Oct. 1. They used data from the Department of Veterans Affairs and received funding from the Mercatus Center at George Mason University and the University of California Office of the President.

“Our study gives researchers, policy makers, and others a strong basis for comparing the long-term effectiveness of COVID vaccines, and a lens for making informed decisions around primary vaccination, booster shots, and other multiple layers of protection, including masking mandates, social distancing, testing, and other public health interventions to reduce the chance of spread,” Dr. Barbara Cohn, the lead author, said in a statement.

The research supports recommendations for many Americans, including all Johnson & Johnson recipients, to get booster shots, she said.

Other studies have shown that COVID-19 vaccine effectiveness has waned over time, leading to the booster recommendations from U.S. health authorities, but this was the first to examine all three available in the United States. It also suggested a lower effectiveness against death than many other studies.

Limitations of the study include not knowing why or where people were tested; researchers required a person to have been tested for COVID-19 to be included in the analysis.

Pfizer, Moderna, Johnson & Johnson, and the U.S. National Institute of Allergy and Infectious Diseases didn’t respond to overnight requests for comment, and haven’t appeared to react publicly to the study.

The findings come after two other studies, both preprints, showed that vaccine effectiveness against infection decreased over time after initial injection.

Swedish researchers, using data from nationwide registries, found that Pfizer’s vaccine dropped in effectiveness to 30–47 percent at day 121–180 from 92 percent at day 15.

“From day 211 and onwards, no effectiveness could be detected,” they said. The Moderna shot also declined in effectiveness, but retained some protection after day 181.

Israeli researchers, meanwhile, extracting data from a nationwide database, found that Pfizer’s vaccine was less effective against both infection and severe disease over time after full vaccination.

So, where are the new & improved vaccines and when will they be available?.

Have the CDC been sitting on their dead asses for the last year?

News Flash for Dummies!

If your product is failing miserably for its intended use, getting more of it is NOT the answer!

[wastedyears]

Where are the democrat/media/big pharma/Faux-xi cheerleaders on here to say the death serum is perfectly and has 98% efficacy?

[goodnesswins]

Sooooo....they are forcing vaccines on workers that only last several months...are they going to force twice a year boosters? This is all ridiculously crazy. (And hopefully falling apart.) Wonder what they’ve got next?

[Ingtar]

Oddly enough, these numbers seem to be twisted in favor of the ones that the CDC/cabal want people to get. Looking at the numbers overseas, before they get squashed, seems to present a different story.

[noiseman]

Isn’t the higher claimed remaining effectiveness in younger people just fraudulently trying to credit the vaccine for what their naturally stronger immune systems are doing?

[Paul R.]

Are you telling me to skip breakfast?

[Paul R.]

It is a normal result. See “Flu vaccines”.

[momincombatboots]

Maybe i haven’t had enough coffee.
Do scientists really state this.. While the vaccinated over time faced a higher risk of getting infected with COVID-19 or dying, the unvaccinated were still more likely to contract the illness or die from it, they said..
Lol here’s the evidence you been asking for brought to you by thise who say we have 9 years before the earth perishes if we don’t send our tax dollars to others.

Sharyl Atkisson did a twitter thread on FB censorship, and the reported loss of efficacy is part of that.

The posts between 6 and 15 exist, just somehow not linked to the thread, and up to 21 or so too. Good collection, lots of links.

1-Facebook’s fake vaccine industry “fact checkers” recently removed a post even though the implications were indisputably supported by peer-reviewed studies, well-established data & CDC. Facebook argued the post was “dangerous” and could result in harm. There was no way to appeal.

2-Post:
“Would a vaccine normally get approved thru regular process if it:
Wears off after a couple of mos.
Doesn’t prevent infectn
Doesn’t prevent spread
May still result in hospitalizatn/death
Requires 3-4 shots in yr
Has side effects
Is for disease that’s non-serious in most?”

3-What follows are examples of scientific data and citations for each part of the question.

And too, there are serious population ramification with universal vaccination of leaky vaccine

Look for studies on Marek’s disease in chickens. Our meat chicken population is universally vaccinated with a vaccine that doesnot prevent infection or spread (leaky), but does reduce seriousness of symptoms. Result is the population loses natural immunity function against that virus.

This is known to the people pushing the vax against humans.

We’re in global Jim Jones territory, with “take the vax” taking the place of “drink the koolaid.” And like Jim Jones, if you don’t, they will hurt you.

To be fair, the vaxed aren’t necessarily harmed, but the human race IS. It becomes dependent, and long term consequences to the human race are unknown.

[CodeToad]

Just don’t buy green bananas.

[Man from Oz]

Your cited example with Marek’s disease in meat birds may not be such a good example to use. Our poultry genetics today see these birds dead and in the supermarkets by 6-8 weeks of age. typically @ 42 days.

My colleagues whom work in the swine industry have cited prior corona virus vaccine admin in their industry. But, then again, pigs are harvested at @ 6 months of age.

Humans, on the other hand..... Just saying.

[Cboldt]

Understood, I think. Your point is that the DIRECT risk to humans is greater, or at least unknow, because we have longer before “hitting the market” as it were.

Still, the reaction of the virus population is to develop strains with greter mortality to the unvaxxed. If the bird, err human, population is deprived of the vax, mass die off. After the viruse has had a chance to beef itself up, of course.

Said another way, the herd becomes dependent on the vax. It’s either that or face a high probability of fatal infection.

If the effectiveness drops, might also the damage to the immune system subside over time?

[catnipman]

“Effectiveness of 2 of 3 COVID-19 Vaccines Used in US Drops Below 50 Percent After 6 Months: Study”

future foundation justifying semi-annual “boosters”, and perpetual masking and “social-distancing ... can’t have the peasants actually conversing with each other you know, they might find out they’re not the only ones who want to revolt ...

[Sirius Lee]

If the effectiveness drops, might also the damage to the immune system subside over time?

In a normal world that would have been tested for over the course of several years, instead of just going ahead and blindly jamming poison into people (and now little kids).

[1217Chic]

My boss and girlfriend went to Aruba, both are jabbed...she got covid and had to stay there an additional 2 weeks in quarantine...He told me he wasn’t feeling well...So that means if I went into the office after testing negative (un-jabbed have to test first) then I could have been more at risk catching it if I was in contact with him.

At this point, it is obvious it isn't about a “safe and effective” injection or people's health and well being. This is biomedical tyranny and loss of freedom unless you follow their dictates and allow them to take ownership of your body. These twisted people could care less about you.
