화이자 코로나 백신 예방효과 90%  (화이자 주가 올라갈까?)
안녕하세요.달빛의 꽃입니다.
미국제약회사 화이자와 독일 바이오엔텍크가 함께 개발중인 신종 코로나바이러스 감염증(코로나19)백신의 효과가 90%이상이라는 중간 결과가 발표되었습니다.
전문가들의 예상을 뛰어넘는 효험을 보여준것으로, 이날 소식에 다우존스 30 산업평균지수가 5% 폭등 출발하는등 글로벌 증시가 일제히 화답했습니다.
화이자는 9일 3상 임상시험 참가자 중 코로나19에 감염된 94명을 분석한 결과 자사 백신이 코로나 19예방에 90%이상 효과를 발휘한것으로 나타났다고 밝혔습니다.
그 동안 과학자들은 최소 75%이상의 효과를 가진 코로나 19 백신을 기대해왔다고 CNBC방송이 전했습니다.
앤서니 파우치 미 국립알레르기, 전염병 연수소 소장은 50%~60%정도만 효과적인 백신도 그런대로 괜찮다고 밝힌바있습니다.
비록 중간 결과이기는 하지만 90%이상의 효과는 일반독감백신의 두배에 가까운것입니다.
미 질병통제 예방센터 (CDC)에 따르면 독감 백신은 감염 위험을 40%~60%낮춰집니다.
화이자 코로나 19 백신의 경우 홍역 백신(93%효과)만큼 예방효과가 강력하다는 뜻입니다.

 



이날 발표는 독립적인 외부 전문가 패널인 데이터 감시위원회가 화이자 -바이오엔테크의 3상 시럼에 관해 내높은 중간 결과로 최종수치는 달라질 수있습니다.
미국과 해외  5개국에서 총 4만 3천 538명을 대상으로 진행중인 3상 시험에서 초기에 발생한 94명의 확진자를 분석한 내용을 담았습니다.

화이자와 바이오엔테크는 임상시험 참가자를 두 그룹을 나눠 한 그룹에는 코로나 19 백신을 투여하고 , 나머지 그룹에 는 플라시보 (가짜약)을 투여했습니다.

그결과 두 실험군을 통틀어 현재까지 94명의 확진자가 나왔는데 이 중 백신을 접종한 참가자 비중은 10%미만에 그쳤습니다. 
임상시험에서 나온 확진자의 90% 이상이 플라시보를 투여한  실험군서 발생했다는 뜻입니다.
백신의 예방 효과가 나타난 시점은 두번째  투여 7일후로, 첫번째 투여일로 부터는 28일 뒤라고 화이자는 설명했습니다.
코로나19백신은 2회 투여해야 면역력이 생깁니다.

앨버트 불라 화이자 최고경영자(CEO)는 성명을 내 감염률 신기록이 세워지고 병원 수용능력이 한계에 가까워지고 경제 재개에 어려움을 겪으면서 전세계가 백신을 필요로 할때 우리가 백신개발에서 중요한 이정표에 도달한 것이라고 자평했다.
불라 CEO는 전세계에 이글로벌 보건 위기를 끝나는데 도움을 줄 돌파구를 제공하는데 한 걸음 가까워졌다며 몇 주안에 백신의 안정성과 효과에 관한  추가 데이터를 공개하겠다고 밝혔습니다.
그는  이날 CNBC 인터뷰에서 우리가 터널 끝에서 마침내 빛을 볼 수 있게 됐다고 생각한다며 지난 100년간 가장 중대한 의학적 발전이 될거라고 믿는다고 자평했습니다.
화이자는 백신 안전에 관한 데이터을 점검한 두 11월 셋째주 미 식품의 약국 (FDA)에 긴급 사용 승인을 신청할 방침입니다.
현재까지 심각한 안전 우려는 관찰되지 않았다고 화이자는 밝혔습니다.
지난 7월27일 시작된 화이자-바이오엔테크의 3상 시험은 총 164명의 확진자가 나올때까지 진행될 방침입니다.
회사측은 올해말까지 1천500만 ~2천만명에게 접종할 수 있는 분량(2회 투여 기준)의 백신을 제조할수 있다고 밝혔습니다.
현재 추세대로라면 내년에 13억회 투여분을 만들어낼 전망입니다.
미 정부와 과학계는 내년 상반기중 화이자를 포함한 코로나19 백신이 상용화될 것으로 기대하고 있습니다.
실현될 경우 코로나 19 가 중국에서  처음 발병한지 12~18개월만으로 세계 백신 개발사에서 최단 기록을 갈아치우게 된다. 지금까지 최단기간에 개발된 백신은 지난 1967년 4년여만에 승인될 볼거리 백신이라고 CNBC는 전했습니다.
그러나 백신의 장기간 안정성과 효험이 아직 입증되지 않았다는 점에서 화이자 백신의 중간 결과가 너무 들떠서는 안된다고 전문가들은 경고하였습니다.
특히 백신의 효능이 얼마나 유지될지는 미지수라고 뉴욕타임스가 지적했습니다.

 

Pfizer Corona vaccine protection 90%. (Will Pfizer stock go up?)
Hello, I'm the flower of the moon.
The interim results show that the new coronavirus infection (Corona 19) vaccine being developed by U.S. pharmaceutical company Huiza and Germany's Biotech is more than 90 percent effective.
Global stock markets responded to the news, with the Dow Jones 30 industrial average jumping 5 percent.
Hua said on the 9th that 94 participants in phase 3 clinical trials who were infected with Corona 19 had found that their vaccines were more than 90 percent effective in preventing Corona 19.
In the meantime, scientists have been expecting a Corona 19 vaccine with at least 75 percent of the effect, CNBC said.
Anthony Pouch, director of the National Allergy and Infectious Hydrogen Division, said a 50-60 percent effective vaccine is fine.
Although it is an interim result, the effect of more than 90 percent is nearly twice that of a regular flu vaccine.
According to the Centers for Disease Control and Prevention (CDC), flu vaccines reduce the risk of infection by 40 to 60 percent.
In the case of the Pfizer Corona 19 vaccine, the preventive effect is as strong as the measles vaccine (93% effect).

The announcement by the Data Surveillance Committee, an independent external panel of experts, is a high-level interim result on Pfizer -Biorentek's three-phase Sirum, and the final figures may vary.
We analyzed 94 early confirmed cases of the three-phase test, which is currently being conducted in the U.S. and five foreign countries, with a total of 43,538 people.

Huizawa Bioentech divided the clinical trial participants into two groups: Corona 19 vaccines for one group and placebo (fake medicine) for the other group.

As a result, 94 confirmed cases have been found in both groups so far, of which less than 10 percent have been vaccinated.
It means that more than 90% of the confirmed cases in clinical trials have occurred in experimental groups with placebo.
Hua explained that the vaccine's preventive effect was seven days after the second dose, and 28 days after the first dose.
Corona 19 vaccine requires 2 doses to produce immunity.

 



In a statement, Pfizer CEO Albert Bulla said, "We have reached an important milestone in vaccine development when the world needs vaccines as a new infection rate record is set, hospital capacity is approaching its limit and the economy is having difficulty resuming."
Bula says she is one step closer to providing a breakthrough to help end the global health crisis and will release additional data on the stability and effectiveness of the vaccine in a matter of weeks.
In an interview with CNBC, he said, "I think we can finally see the light at the end of the tunnel," adding, "I believe it will be the most significant medical development in the last 100 years."
Hua plans to apply for emergency use approval from the Food and Drug Administration (FDA) in the third week of November after checking data on vaccine safety.
Hua says no serious safety concerns have been observed so far.
Pfizer-Bioentech's three-phase test, which began on July 27, will run until a total of 164 confirmed cases.
By the end of this year, the company said it could manufacture vaccines (based on two doses) that could be administered to between 15 million and 20 million people.
If the current trend continues, it will generate 1.3 billion doses next year.
The U.S. government and the scientific community expect the Corona 19 vaccine, including Huiza, to be commercialized in the first half of next year.
If realized, Corona 19 would break the world's shortest record in vaccine development just 12 to 18 months after its first outbreak in China. CNBC says the vaccine developed in the shortest period of time is something to see that will be approved in 1967 for the first time in 1967, CNBC said.
However, experts warn that the interim results of the Pfizer vaccine should not be too exciting, given that the long-term stability and effectiveness of the vaccine have yet to be proven.
In particular, the New York Times says it remains uncertain how effective the vaccine will be.
