Latest Vaccine News

[Cuddles]

You have any factual statements to make about the results of studies using Sinovac -- many of them comparing results directly in countries against other vaccines in the same time period.

Factual statements below:

huh, good to know it's comparable to Pfeizer at preventing serious illness and death. No wonder Chile's doing so well.

Studies show Sinovac's been fairly effective at preventing hospitalizations and death (I've posted it). GWB has chosen to ignore this.

Hahahahh
Ya took the words right out of my mouth.

So tell us...

How many doses of Sinovac are required in Singapore to be considered fully vaccinated?

How many doses of Pfizer are required in Singapore to be considered fully vaccinated?

Let's see if you have the ability to walk through the intellectual basics of the situation.

Factual statements above

And once again you are pushing nonsense --- Sinovac is not way comparable to Pfizer.

"Sinovac's COVID-19 vaccine was 58.5% effective in preventing symptomatic illness among millions of Chileans who received it between February and July, the Chilean health authorities said on Tuesday, while Pfizer's COVID-19 shot was 87.7% effective."

If we have GRU propaganda downplaying the effectiveness of western vaxxes. Do we have Langley propaganda downplaying the effectiveness of Gynese vaxxes?

Chile began one of the world's fastest inoculation campaigns against COVID-19 in December, having now fully vaccinated more than 60% of its population, predominantly with Sinovac's (SVA.O)CoronaVac.

That vaccine was 86% effective in preventing hospitalization, 89.7% effective in preventing admission to intensive care units and 86% effective in preventing deaths within the population between February and July, health official Dr Rafael Araos said in a press conference on Tuesday.

In April, the same study found that CoronaVac was 67% effective in preventing symptomatic illness, 85% effective in preventing hospitalizations and 80% effective in preventing deaths, suggesting its capacity to prevent the more serious impacts of the virus has strengthened, while its capacity to stop symptomatic illness diminished.

The inactivated inoculation, given to more than 10 million Chileans, was slightly less effective in preventing hospitalization and deaths than the mRNA vaccine, which was administered to fewer than half a million people, according to the study, published Wednesday in the New England Journal of Medicine.

The research was conducted from February through May, when the alpha and gamma strains of the virus were the variants of concern most frequently detected in Chile. Preliminary data released in April found CoronaVac was 67% effective in preventing symptomatic Covid-19 infections and warded off 80% of fatalities from the disease.

The final results suggest CoronaVac, the mainstay of Chile’s vaccination strategy, provides an effective shield against Covid-19, including severe disease, consistent with the results of mid-stage trials, the authors said.

As of May 10, Chile’s Ministry of Health has administered almost 14 million CoronaVac doses, including enough to fully immunize 6.36 million people. In comparison, 2.4 million doses of the Pfizer-BioNTech vaccine had been administered. Individuals 16 years or older are eligible to be immunized, according to the national vaccination schedule.

And yet Sinovac was less effective than all the other western vaccines in studies around the earth... whether you talk about preventing symptomatic disease, severe disease, or death. And these studies have now been done against a wide range of variants.

"Sinovac's 51% efficacy only just exceeds the WHO's 50% efficacy threshold for Covid-19 vaccines and a lack of public clinical data to back up manufacturers' often inconsistent claims hampers public acceptance of the vaccine."

China’s Sinovac Vaccine Under Scrutiny As Covid Soars In Highly Vaccinated Countries

They Relied on Chinese Vaccines. Now They’re Battling Outbreaks.
More than 90 countries are using Covid shots from China. Experts say recent infections in those places should serve as a cautionary tale in the global effort to fight the disease.
https://www.nytimes.com/2021/06/22/business/economy/china-vaccines-covid-outbreak.html

"In the Seychelles, Chile, Bahrain and Mongolia, 50 to 68 percent of the populations have been fully inoculated, outpacing the United States, according to Our World in Data, a data tracking project. All four ranked among the top 10 countries with the worst Covid outbreaks as recently as last week, according to data from The New York Times. And all four are mostly using shots made by two Chinese vaccine makers, Sinopharm and Sinovac Biotech."

"“If the vaccines are sufficiently good, we should not see this pattern,” said Jin Dongyan, a virologist at the University of Hong Kong. “The Chinese have a responsibility to remedy this.”"

I don't. I just read the part about 3 shots.

But still, apparently our stuff isn't working real well either.

This is a totally different thing, but ya know smart folks knew for years that pediatricians and doctors over-prescribed antibiotics. They'd hand them out for damn near anything. Skin your knee... take these for two weeks. Stuffy head(?), here take these.

It went on for 40 years. Know what happened? When people really needed antibiotics, like when they went septic or something, or maybe pneumonia in a cardiac patient, stuff like that.... guess what, the antibiotics didn't work because their bodies had become used to them.

Not saying that's the case with... well we're on #3 now... but part of me says we are playing into this virus' hand.

But again, not my wheelhouse.

That vaccine was 86% effective in preventing hospitalization, 89.7% effective in preventing admission to intensive care units and 86% effective in preventing deaths within the population between February and July, health official Dr Rafael Araos said in a press conference on Tuesday.

The government also published data on the effectiveness of other vaccines administered in Chile, made by Pfizer BioNTech (PFE.N), (22UAy.DE) and AstraZeneca (AZN.L).

Pfizer's vaccine was 87.7% effective in preventing symptomatic COVID-19 in the same period, 98% effective in preventing intensive care admission and 100% effective in preventing death, Araos said.

AstraZeneca's was 68.7% effective in preventing symptomatic COVID-19 in the same period, 98% effective in preventing intensive care admissions and 100% effective in preventing death, Araos said.

Chile's study examined the vaccines' effectiveness among different cohorts of people who either received two doses of the specified vaccine, partial doses of the vaccine or no vaccine at all.

The CoronaVac part of the study examined a group of 8.6 million people, the Pfizer BioNTech part studied a group of 4.5 million people and the AstraZeneca part looked at a group of 2.3 million people.

A study conducted by researchers in China found that the SinoVac and SinoPharm vaccines had a combined efficacy of 70% in preventing an infection caused by the more contagious Delta variant in the city of Guangzhou. The study, which has yet to be peer reviewed, also noted that the shots were 100% effective in preventing severe infections and deaths.
However, a Brazilian preprint study comparing SinoVac to the AstraZeneca COVID-19 vaccine found that recipients of the Chinese-made vaccine had lower protection levels against the virus.
SinoVac recipients were 54% less likely to contract COVID-19 and 74% less likely to die of the virus compared to the unvaccinated. The efficacy waned in the older population, reducing the risk of death by only 35% in people over the age of 80. In comparison, AstraZeneca reduced the risk of infection by 70% and the risk of death by 90%.

The Singaporean government had previously excluded people who received the SinoVac shots from the country’s total count of vaccinations. Health Minister Ong Ye Kung cited inadequate efficacy data as the reason for the move.

"We don't really have a medical or scientific basis or have the data now to establish how effective SinoVac is in terms of infection and severe illnesses on Delta," Ong said during a July media briefing, according to Reuters.

Singapore’s Ministry of Health later announced it will consider people who received vaccine shots included in the World Health Organization’s emergency use list, such as SinoVac, Sinopharm and AstraZeneca, as fully vaccinated, in an effort to be more “inclusive.”

“What is important now is the difference between those who are vaccinated and not vaccinated and less so between different vaccines,” Ong said at a press conference in early August.

Despite this, the Singaporean government is still offering third doses of vaccines to residents who had taken the SinoVac jab as part of a “heterologous vaccination strategy.”

"We have not stopped them although data is still lacking considering what the effectiveness is of this strategy using two different vaccines – we call this a heterologous vaccination strategy," Director of Medical Services Kenneth Mak said during a virtual doorstop interview.

The latest data also found that Sinovac has an 86% effectiveness in preventing hospitalizations, 89.7% in preventing admission to intensive care units and 86% in preventing COVID deaths. These show increase in April data figures, wherein the vaccine was only 85% effective in preventing hospitalizations, 89% effective in preventing ICU admission and 80% effective in preventing deaths.

Chilean health official Dr. Rafael Araos said a reduction in the vaccine’s effectiveness was expected, especially with the emergence of new and more contagious variants.

"If Delta becomes more prevalent and the vaccine has a weaker response, we could observe a faster fall (in effectiveness)," he said during a press conference on Tuesday.

The data comes after a study published on medRxiv last week found that a third shot of the Sinovac COVID-19 vaccine given six to eight months after the second dose could generate a remarkable increase in antibody levels in recipients.

Among the 540 study participants who received the third dose, the levels of neutralizing antibody increased three-fold two weeks after the shot.

The study also found that giving a third dose 28 days after the second dose induced only a third of the antibody levels compared with a third dose given half a year after the second dose, Global Times noted.

The real-world data also comes after China’s Shanghai Fosun Pharmaceutical, in late July, announced that it was partnering with BioNTech to develop a booster vaccine using mRNA technology, similar to that used in COVID-19 vaccines developed by Pfizer and Moderna.

The shot, which is expected to be called Comirnaty, will begin its domestic trial production by the end of the month. It is currently in the administrative review stage.

"If Delta becomes more prevalent and the vaccine has a weaker response, we could observe a faster fall (in effectiveness)," he said, adding his voice to calls for a third, booster dose to be issued.

The government also published data on the effectiveness of other vaccines administered in Chile, made by Pfizer BioNTech (PFE.N), (22UAy.DE) and AstraZeneca (AZN.L).

Pfizer's vaccine was 87.7% effective in preventing symptomatic COVID-19 in the same period, 98% effective in preventing intensive care admission and 100% effective in preventing death, Araos said.

nothing on effectiveness in the article

6th source:

Since then, the Chinese shot has become the most widely administered one in the country.

Butantan said that if the second dose is delayed by more than two weeks, the efficacy rises to 62.3%. The vaccine has an efficacy of between 83.7% and 100% at preventing those infected from requiring medical assistance, it said.

7th source:

Plasma samples taken from eight people vaccinated with Sinovac’s CoronaVac failed to efficiently neutralize the P.1 lineage variant, or 20J/501Y.V3, researchers said in a paper published on Monday ahead of peer-review.

US Pediatricians: Antibiotics are Over-prescribed to Children

On an average, 10 million antibiotic prescriptions annually are unnecessary. This, according to Dr. Hersh, is a very disturbing trend. He suggests that doctors should “wait and watch”, when the diagnosis is not clear, instead of prescribing antibiotics straight away. He urges the parents and family members to question the doctor as to why he has prescribed antibiotic. It is better to bear with a mild infection and let it take its natural course, rather than taking antibiotic. This will make the antibiotic more effective in case of bigger infections later on.
