ビオンテックのCEO「新たな変異ウイルスへの予防効果はかなり低い」 7か月でほぼゼロに

 新型コロナウイルスのファイザー製ワクチンについて共同開発したビオンテックのCEOが接種から7カ月で抗体レベルが減少しているとの見解を示した。

　ウォール・ストリート・ジャーナルは25日、ファイザーとワクチンを共同開発したドイツのビオンテックのウグル・サヒンCEOのインタビューを報じた。サヒンCEOは「接種後7カ月が経過した一部の患者の中で抗体のレベルが減少している」との見解を明らかにした。さらに「新たな変異ウイルスへの予防効果はかなり低い」とも言及し、抗体の減少に加えてデルタ株への免疫力の低下を指摘した。

　一方で「ほとんどが重症化を避けることができ3回目の接種は恐らくまだ必要ないだろう」との見方も示し、追加接種の是非について「それぞれの政府が判断すべきだ」としている。（ANNニュース）

感染拡大阻止には何の役にもたたない新型コロナワクチン

コロナワクチン接種後の抗体レベル、毎月４０％のペースで低下　今年一月に接種した場合、感染に対する有効率はたった１６％

要するにワクチンを打っても感染はまったく防げない。摂取しても他人にも感染させる。接種済スーパースプレッダーも既に確認されてる。

感染拡大阻止には何の役にもたたない。

ワクチンパスポートとかワクチン強制推進派はものすごい低能か悪意の塊ですな。

How the Delta variant upends assumptions about the coronavirus

July 26 (Reuters) - The Delta variant is the fastest, fittest and most formidable version of the coronavirus that causes COVID-19 the world has encountered, and it is upending assumptions about the disease even as nations loosen restrictions and open their economies, according to virologists and epidemiologists.

Vaccine protection remains very strong against severe disease and hospitalizations caused by any version of the coronavirus, and those most at risk are still the unvaccinated, according to interviews with 10 leading COVID-19 experts.

But evidence is mounting that the Delta variant, first identified in India, is capable of infecting fully vaccinated people at a greater rate than previous versions, and concerns have been raised that they may even spread the virus, these experts said.

As a result, targeted use of masks, social distancing and other measures may again be needed even in countries with broad vaccination campaigns, several of them said.

Israel recently reinstated mask-wearing requirements indoors and requires travelers to quarantine upon arrival.

U.S. officials are considering whether to revise mask guidance for the vaccinated. Los Angeles County, the most populous in the United States, is again requiring masks even among the vaccinated in indoor public spaces.

"The biggest risk to the world at the moment is simply Delta," said microbiologist Sharon Peacock, who runs Britain's efforts to sequence the genomes of coronavirus variants, calling it the "fittest and fastest variant yet."

Viruses constantly evolve through mutation, with new variants arising. Sometimes these are more dangerous than the original.

The major worry about the Delta variant is not that it makes people sicker, but that it spreads far more easily from person to person, increasing infections and hospitalizations among the unvaccinated.

Public Health England said on Friday that of a total of 3,692 people hospitalized in Britain with the Delta variant, 58.3% were unvaccinated and 22.8% were fully vaccinated.

In Singapore, where Delta is the most common variant, government officials reported on Friday that three quarters of its coronavirus cases occurred among vaccinated individuals, though none were severely ill.

Israeli health officials have said 60% of current hospitalized COVID-19 cases are in vaccinated people. Most of them are age 60 or older and often have underlying health problems.

In the United States, which has experienced more COVID-19 cases and deaths than any other country, the Delta variant represents about 83% of new infections. So far, unvaccinated people represent nearly 97% of severe cases.

Dr. Monica Gandhi, an infectious diseases doctor at the University of California, San Francisco, said many vaccinated people are "so disappointed" that they are not 100% protected from mild infections. But the fact that nearly all Americans hospitalized with COVID-19 right now are unvaccinated "is pretty astounding effectiveness," she said.

'TEACHING US A LESSON'

"There is always the illusion that there is a magic bullet that will solve all our problems. The coronavirus is teaching us a lesson," said Nadav Davidovitch, director of Ben Gurion University's school of public health in Israel.

The Pfizer Inc (PFE.N)/BioNTech vaccine, one of the most effective against COVID-19 so far, appeared only 41% effective at halting symptomatic infections in Israel over the past month as the Delta variant spread, according to Israeli government data. Israeli experts said this information requires more analysis before conclusions can be drawn.

"Protection for the individual is very strong; protection for infecting others is significantly lower," Davidovitch said.

A study in China found that people infected with the Delta variant carry 1,000 times more virus in their noses compared with the original version first identified in Wuhan in 2019.

"You may actually excrete more virus and that's why it's more transmissible. That's still being investigated," Peacock said.

Virologist Shane Crotty of the La Jolla Institute for Immunology in San Diego noted that Delta is 50% more infectious than the Alpha variant first detected in the UK.

"It's outcompeting all other viruses because it just spreads so much more efficiently," Crotty said.

Genomics expert Eric Topol, director of the Scripps Research Translational Institute in La Jolla, California, noted that Delta infections have a shorter incubation period and a far higher amount of viral particles.

"That's why the vaccines are going to be challenged. The people who are vaccinated have got to be especially careful. This is a tough one," Topol said.

In the United States, the Delta variant has taken hold just as many Americans - vaccinated and not - have stopped wearing masks indoors.

"It's a double whammy," Topol said. "The last thing you want is to loosen restrictions when you're confronting the most formidable version of the virus yet."

The development of highly effective vaccines may have led many people to believe that once vaccinated, COVID-19 posed little threat to them.

"When the vaccines were first developed, nobody was thinking that they were going to prevent infection," said Carlos del Rio, a professor of medicine and infectious disease epidemiology at Emory University in Atlanta. The aim was always to prevent severe disease and death, del Rio added.

The vaccines were so effective, however, that there were signs they also prevented transmission against prior coronavirus variants.

"We got spoiled," he said.
