CDC Funded Study Shows No Significant Difference in COVID-19 Transmission Between Vaccinated and Unvaccinated

The Covid Hoax implodes more and more every day.

TAKE THE TIME TO READ THROUGH THIS.

I ONLY WONDER HOW THE ARCH DECIEVER MOZZZZZZZZZ WILL SPIN ALL THIS.

The Centers for Disease Control and Prevention (CDC) COVID response team published a study on medRxiv – a collaborative project jointly run by Cold Spring Harbor Laboratory, Yale University, and BMJ, a global healthcare knowledge provider – concluded that there is no significant difference in transmission potential of vaccinated and unvaccinated persons infected with the COVID-19 “Delta variant” in federal prison during an outbreak between July to August 2021.

Dr. Jordan Peterson, a clinical psychologist shared this on his Twitter account :

The study showed that there is “no significant differences were detected in duration of RT-PCR positivity among fully vaccinated participants (median: 13 days) versus those not fully vaccinated (median: 13 days; p=0.50), or in duration of culture positivity (medians: 5 days and 5 days; p=0.29)” among the 95 eligible participants out of 190, of whom 78 were fully vaccinated and 17 were not fully vaccinated.

The findings showed that “prevention and mitigation measures should be applied without regard to vaccination status for persons in high-risk settings or those with significant exposures.” 

In this investigation, we found no statistically significant difference in transmission potential between vaccinated persons and persons who were not fully vaccinated. Therefore, our findings indicate that prevention and mitigation measures should be applied without regard to vaccination status for persons in high-risk settings or those with significant exposures. In congregate settings, and correctional and detention facilities in particular, post-exposure testing and quarantine remain essential tools to limit transmission when cases are identified, in addition to other recommended prevention measures. Our data add to a growing body of evidence characterizing transmission potential from vaccinated persons. Future studies of transmission potential from vaccinated persons with infection, incorporating similar laboratory-based markers as well as evidence of transmission from secondary attack rates and network analysis, may help to further describe the contributions of vaccinated persons in chains of transmission as the pandemic evolves and new variants emerge.

The study confirmed that vaccinated individuals are still at risk of widespread outbreaks when the virus is introduced into congregate settings, even when vaccination coverage is high.

The evidence that vaccinated persons can transmit SARS-CoV-2 to others suggests that there is continued risk of widespread outbreaks when the virus is introduced into congregate settings, even when vaccination coverage is high. In particular, because of the potential for rapid transmission and high prevalence of underlying health conditions in incarcerated populations, persons living or working in correctional facilities should quarantine after exposure to SARS-CoV-2, regardless of vaccination status.

Line 313 of the study states:

This report is subject to several limitations. Due to the small proportion of participants who were not fully vaccinated (17), statistical comparisons on the basis of vaccination status were underpowered, and negative findings reported here warrant cautious interpretation. To increase the sample size of this group, two partially vaccinated participants were included, potentially diluting the characteristics of unvaccinated participants. However, our conclusions did not change when analyses were performed excluding these two participants. Similarly, only four participants had known prior infection, of which a higher proportion occurred in those not fully vaccinated; therefore, these participants may appear to have slightly greater immunological protection than those without prior infection. On average, unvaccinated participants enrolled earlier in the outbreak and later in their course of infection than vaccinated participants; we utilized Turnbull estimation in survival analyses to account for the possibility of interval censoring in this population. All symptom data was self-reported and collected at the end of the specimen collection period, which may have impacted the accuracy of participants’ recall related to the date of symptom onset.

This article is a preprint and has not been peer-reviewed but the same authors published a similar report on Delta variant infections among incarcerated persons in a Federal Prison — Texas, July–August 2021 with similar findings posted on the CDC website. 

During a COVID-19 outbreak involving the Delta variant in a highly vaccinated incarcerated population, transmission rates were high, even among vaccinated persons. Although attack rates, hospitalizations, and deaths were higher among unvac- cinated than among vaccinated persons, duration of positive serial test results was similar for both groups. Infectious virus was cultured from vaccinated and unvaccinated infected persons.

What are the implications for public health practice?

Even with high vaccination rates, maintaining multicomponent prevention strategies (e.g., testing and masking for all persons and prompt medical isolation and quarantine for incarcerated persons) remains critical to limiting SARS-CoV-2 transmission in congregate settings where physical distancing is challenging.

A similar study from Lancet showed that fully vaccinated people in UK are just as likely to spread the Delta variant of Covid within households as unvaccinated.

“Households are the site of most SARS-CoV-2 transmission globally.19 In our cohort of densely sampled household contacts exposed to the delta variant, SAR was 38% in unvaccinated contacts and 25% in fully vaccinated contacts. This finding is consistent with the known protective effect of COVID-19 vaccination against infection.8, 9 Notwithstanding, these findings indicate continued risk of infection in household contacts despite vaccination.” the study said.

New Study: Fully Vaccinated People Just as Likely to Spread Delta Variant Within Households as Unvaccinated

Fully vaccinated people are just as likely to spread the Delta variant of Covid within households as unvaccinated, according to a new Lancet study. Researchers in the United Kingdom examined 621 symptomatic people over one year. “Households are the site of most SARS-CoV-2 transmission globally.19 In our cohort of densely sampled household contacts exposed to … Continue reading

So jus how is this a epidemic of the unvaccinated?  T he evidence shows it is not.

Households are the site of most SARS-CoV-2 transmission globally.19 In our cohort of densely sampled household contacts exposed to the delta variant, SAR was 38% in unvaccinated contacts and 25% in fully vaccinated contacts. This finding is consistent with the known protective effect of COVID-19 vaccination against infection.8, 9 Notwithstanding, these findings indicate continued risk of infection in household contacts despite vaccination.” the study said.

I’ll take less likely to die every time….get your vaccine and stick with moz

I think the point here is that it brings into question the basis of the vaccine passport and all other restrictions (like loss of employment) applied to unvaxxed people. If the vaccinated spread it around just as easily, then what is your basis of exclusion?

Well firstly it’s a study with 83 participants, 17 of whom had not been vaccinated. Why….perhaps they were a few tough guys showing off. Not a random sample. 

Secondly it’s talking to vaccinated people vs unvaccinated people spreading the disease….not getting the disease. It’s still not in contention, even if you spread it evenly vaccinated  or unvaccinated …that you are less likely to get it if you are vaccinated, and much less likely to die.

That being true it’s obviously better to be vaccinated. But I agree it devalues the notion of a vaccine passport.

…that you are less likely to get it if you are vaccinated, and much less likely to die.

Yep, and then it comes down to body autonomy. You decide the risk you want to take for yourself while you don't necessarily pose a bigger risk to anyone else because of it.

True about the small sample, but you have to say that when you look at a country like Germany now experiencing their highest infection rate of the entire pandemic with almost 70% fully vaccinated, that type of data also strongly hints at the vaccinations doing little to nothing to curb infections. When your 70% vaxxed infection rate hits a peak of more than double your 0% vaxxed infection rate peak, you'll have a hard time convincing anyone that the vaccines curb infections.

But have you looked at European football stadiums recently….packed to the gills. The Dutch Grand Prix was a crowd scene like a rock concert.

The pre vaccination world looked nothing like that, nor was Delta around.

The best guide is still controlled studies. Here are the results quoted by the Mayo Clinic, America’s top hospital:

While research suggests that COVID-19 vaccines are slightly less effective against the variants, the vaccines still appear to provide protection against severe COVID-19. For example:

• Early research from the U.K. suggests that, after full vaccination, the Pfizer-BioNTech COVID-19 vaccine is 88% effective at preventing symptomatic COVID-19 virus caused by the delta variant. The vaccine is 96% effective at preventing severe disease with the COVID-19 virus caused by the delta variant. The research also showed that the vaccine is 93% effective at preventing symptomatic COVID-19 virus caused by the alpha variant.
• Early research from Canada suggests that, after one dose, the Moderna COVID-19 vaccine is 72% effective at preventing symptomatic COVID-19 virus caused by the delta variant. One dose of the vaccine is also 96% effective at preventing severe disease with the COVID-19 virus caused by the delta variant.
• The Janssen/Johnson & Johnson COVID-19 vaccine is 85% effective at preventing severe disease with the COVID-19 virus caused by the delta variant, according to data released by Johnson & Johnson

The bottom like is you can’t pass the disease on unless you have it….and even with Delta, for which current vaccines were not specifically designed, you are still 5 to 10 times less likely to get the disease if you are vaccinated.

Germany has a population of 84 million …even if 75% are vaccinated, that would leave some 20 million unvaccinated people and only 7% have received their booster shots which are now necessary as effectiveness wanes after 6 months.

It’s not perfect, but it’s the best tool we have.

"It’s not perfect, but it’s the best tool we have."

Short term...the long term effects of the vax can't be known yet...it remains a gamble...and I don’t like betting...rather be safe...but I'm not given that option. 

The non Covid deaths have climbed substantially since the vaxx started. Explain that away.

Given transision is the same how can you say this is an epidemic of the unvaxxed. You cant unless you are a liar.

It appears any benefits from the vaxx only last afew moths and then its more booster forever more. Destroying your immune system and causing havoc and death in many ways.

It is disgraceful that mampara mozzz defends all this saying the vaxx are safe. He is a bald faced liar. He is lucky he is no medical authority lest he be tried for murder like it looks Gates is going to be in India.

Looking forward to Fauci being taken to court as well. The Covid hoax is unravelling and despite the best efforts of the Globalist allies folk are waking up to the dangers of these deadly gene therapies

The gamble is not getting vaccinated. Look at the UK…

May 2020  empty, stadiums, pubs, concert halls no schools/no Delta/no vaccinations…over 1000 deaths  a day.

March 2021….partial engagement, but still empty stadiums etc/full Delta/limited vaccinations over 1500 deaths  a day.

November 2021….full engagement, stadiums packed to the rafters/Delta dominant/extensive vaccinations.…..less than 200 deaths a day 

…..the numbers can’t be clearer.

.

Reports in the UK suggest that after 4 months the vaccine becomes totally ineffective at preventing infections from Delta. Only in the first few months, does it reduce the chances of being infected.
Israel has also stated this, as they were the first country to be highly vaccinated using a good vaccine. 
It would have been more effective for a "longer" period of time with earlier variants- but not Delta.

However, there is some early indication that a 3-jab regime is much more effective than a 2 dose. The third jab is raising anti-bodies to a much higher level than after the 2nd dose.
This will reduce the chances of being infected- which is essential to turn it into an endemic. 

A 4th dose may be required, or the occasional booster. These make the anti-body response higher, which will last longer- and help prevent severe symptoms.

All drugs go through the same trial procedures, not just Covid.
So, unless Bill Gates has spiked the vaccines to cause everyone to explode on a certain date, things are looking good for the long term. 

What amazes me about the anti vax  crowd is they will take statins, blood pressure meds, have coronary bypasses….fly in jets putting their lives into the hands of two pilots they know nothing about, drive through intersections without looking if they have a green light. But think vaccines are somehow these time bombs that are going to blow them up.

Weird!

Trials for new medication takes years...most vaccines takes decades to make sure it's safe...now we have lot's of covid shots declared safe in less than a year and nobody is questioning the logic....and that for a disease with a relatively low death rate. That's weird.

I also had side effects from my first jab that were pretty severe, but they were gone in a few days. 
The immediate short term side effects apparently feel like having Covid. 

AstraZeneca probably has more side effects than say, Pfizer.

Zero side effects….nor has anybody in my family.

I am fully vaxxed and so is my entire extended family, worst complaint is a sore shoulder.

All but one at my business and their family is vaxxed and no issues.

You can lean anyway you like looking at individual or small groups, it means shit, for the truth you need a large data base to get a true insight and all of the anti vaxxers is based on "I known a mans who's brother sisters aunt friend got a headache" type of nonsense.

This is NZ stats for yesterday but I will simplify it for the anti vaxxer morons 83% in hospital with no vax or only received one shot. The figures are staring you in the face but unfortunately you cant educate the stupid no matter how hard we try. 

The vaccination status of current hospitalisations - which includes Northern Region wards only - is:

• Unvaccinated or not eligible - 53 cases or 70 percent
• Partially immunised and less than seven days from second dose or have only received one dose - 10 cases or 13 percent
• Fully vaccinated for at least seven days before being reported as a case - 12 cases or 16 percent
• Unknown - 1 case or 1 percent.

To make those numbers meaningful you have to know what percentage of the population is in each category as well as what percentage of cases the segment rep resents. Did they teach you that science in NZ?

Sorry  thought I had added that in.

Currently 93% have received at least 1 shot , 86% have 2 shots

Sixteen percent  of cases from a group that comprises 86% of the population tells the story.
