周三,美国国家过敏和传染病研究所(NIAID)主任安东尼·福西博士澄清了美国COVID-19的状况,包括何时可以提供疫苗。
“为了得到一种可以实际部署给人们使用的疫苗,最好至少需要一年到一年半的时间,”福西告诉美国有线电视新闻网元旦主持人约翰·伯曼。
根据约翰·霍普金斯大学的追踪报告,新冠状病毒的病例数量持续上升,截至周三,全球已有超过81,000人被感染。随着人数的增加,公众的关注程度也在增加,这自然会引发关于预防措施的下一个问题。
周二在印度的新闻发布会上,唐纳德·特朗普总统告诉记者,美国“非常接近”疫苗。一些人质疑他的说法的有效性,甚至指责他撒谎,而另一些人则利用生物技术公司Moderna向研究人员运送疫苗的消息来证明总统是正确的。
福西告诉伯曼,疫苗的时间表存在混乱,因为有必要采取措施让公众获得疫苗。他说,官员们“接近”开始试验的第一阶段,以确定安全性,并预计将在一个半月到两个月内进行。然而,他断言,一种疫苗可能需要一年多的时间才能大规模地用于人类。
2月5日,维尔Path大学实验室的一名科学家致力于寻找新冠状病毒的有效治疗方法。美国国家过敏和传染病研究所的安东尼·福奇博士说,疫苗还需要一年左右才能向公众提供。
病毒基因组序列公布后不久,美国官员开始研制疫苗。Fauci确认的在周二的新闻发布会上,这一过程“至少是准时的,甚至可能比预期的好一点”,这让他们有望创下一项记录,即官员们在第一阶段试验中最快地识别出一种病原体并将其植入人体。
周一,莫德纳宣布,它已经将第一批潜在的COVID-19疫苗运送到NIAID,用于第一阶段的研究。
Fauci称,试验开始后,需要三到四个月来确定疫苗是否安全,以及是否产生预期的保护性反应。然后,将不得不进行一项更大规模的试验,涉及数百人——相比之下,第一阶段共有45人。
“这本身,即使以火箭的速度,也至少需要6到8个月,”福西说。
Fauci告诉人们不要对疫苗研发的漫长时间表感到气馁,因为这种新的冠状病毒有可能会“远远超出这个季节,进入下一个季节”因此,即使疫苗不能解决接下来几个月的问题,它在未来还是有好处的。
CORONAVIRUS VACCINE 'AT LEAST A YEAR' AWAY 'AT BEST' FROM BEING PUBLICLY AVAILABLE, NATIONAL HEALTH OFFICIAL SAYS
On Wednesday, Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases (NIAID), clarified information about the state of COVID-19 in the United States, including when a vaccine could be made available.
"In order to get a vaccine that's practically deployable for people to use, it's going to be at least a year to a year and a half at best," Fauci told CNN New Day host John Berman.
The number of cases of the new coronavirus continue to rise, and as of Wednesday, more than 81,000 people have become infected worldwide, according to a tracker maintained by Johns Hopkins University. As the number increases, so has the level of concern among the general public, making the natural next questions about preventive measures.
During a press conference in India on Tuesday, President Donald Trump told reporters that America was "very close" to a vaccine. Some questioned the validity of his claim, even accusing him of lying, while others used the news that Moderna, a biotech company, shipped a vaccine to researchers as proof that the president was correct.
Fauci told Berman that there's confusion over the vaccine's timeline because of the steps that are necessary to make it available to the public. He said officials are "close" to starting the first phase of a trial to determine the safety and expected that to occur in one and a half to two months. However, he asserted that it could be more than a year before a vaccine is administered to humans on a wide scale.
A scientist at the VirPath university laboratory, on February 5 works to find an effective treatment for the new coronavirus. Dr. Anthony Fauci of the National Institute of Allergy and Infectious Diseases, said a vaccine is about a year away from being made available to the public.
American officials began working on a vaccine shortly after the virus' genome sequence was made available. Fauci confirmed during a press conference on Tuesday that the process was "on time at least or maybe even a little better," than was hoped for, putting them on track to set a record for the fastest officials have identified a pathogen and put it into a human during a phase 1 trial.
On Monday, Moderna announced that it had shipped its first batch of a potential COVID-19 vaccine to the NIAID to be used in the phase 1 study.
After the trial starts, it will require three to four months to determine if the vaccine is safe and whether it yields the predicted protective response, according to Fauci. Then, a larger trial will have to be conducted, involving hundreds of people—as compared to the phase 1 pool of 45 people.
"That, itself, even at rocket speed, would take at least an additional six to eight months," Fauci said.
Fauci told people not to get discouraged by the lengthy timeline for the development of a vaccine because it's possible the new coronavirus will go "well beyond this season into next season." So, even if the vaccine doesn't solve the problems of the upcoming months, it could be beneficial in the future.
