尽管唐纳德·特朗普总统声称COVID-19“解决方案”很可能是可行的”早在年底之前一名领导负责批准疫苗的机构的白宫冠状病毒特别工作组成员周日拒绝提供疫苗最终研发的时间表。
“我不能预测什么时候会有疫苗，”食品和药物管理局局长斯蒂芬·哈恩博士在美国广播公司的“本周”周日节目中说，并补充道，“是的，我们正看到疫苗开发的空前速度。但是……我们对美国人民的庄严承诺是，我们将根据疫苗的数据和科学，就疫苗的安全性和有效性做出决定。”

周六，特朗普在华盛顿发表了7月4日的演讲，在病毒治疗研究和开发的速度以及COVID-19对检测呈阳性的个人的影响方面，他的语气更加乐观。
“我们正在释放我们国家的科学智慧，我们很可能在年底之前就有一个治疗和/或疫苗解决方案，”特朗普说。此前他曾大力宣传美国的检测工作，并声称，在没有证据的情况下，“99%的冠状病毒病例”是“完全无害的”

《本周》的联合主持人玛莎·拉德兹对哈恩的后一种说法提出了质疑，但拒绝加入总统的角色塑造。
“我们有超过129，000人死亡，超过280万病例，你认为有多少病例是无害的?”拉德达茨问道。
“我想说的是，你知道，无论如何，我们都不想在这个国家发生，”专员说。“任何死亡，任何情况都是悲剧性的，我们想尽一切努力来防止这种情况。”
哈恩是一名训练有素的放射和医学肿瘤学家，他于2019年12月成为美国食品和药物管理局局长。周四说他对目前开发冠状病毒疫苗的努力持“谨慎乐观”的态度，指出“年底或明年初”是可能的完成日期。
美国人对注射冠状病毒有些犹豫，这使得人们不清楚疫苗能在多大程度上阻止这种流行病的继续蔓延。六月，一个美国广播公司新闻民意测验发现27%的成年人说他们要么“肯定”要么“可能”得不到疫苗Raddatz在周日询问了Hahn这个数字。
“这是一个相当大的数字，这是令人担忧的，当然，这个国家的疫苗问题已经存在了很多年，”他说，同时解释说，美国食品和药物管理局关注的是疫苗的“安全性”和“有效性”。“我想向美国人民保证这一点，并让他们相信我们在工作。”
美国的COVID-19病例在过去一周继续激增，包括亚利桑那州、佛罗里达州和得克萨斯州在内的大州都在努力控制最近的疫情。
这些州的地方领导人也在周日的“本周”节目中露面，详细描述了随着病例增多和医院不堪重负，他们所在社区面临的一些困境。
“我们看到的是，一厢情愿的想法既不是好的经济政策，也不是好的公共卫生政策，”法官莉娜·伊达尔戈(Lina Hidalgo)说，她是德克萨斯州哈里斯县的首席执行官，哈里斯县是该州人口最多的县，包括休斯顿市。
伊达尔戈哀叹道，今年早些时候，她被州政府剥夺了发布在家办公令的能力，并批评政府官员格雷格·艾伯特(Greg Abbott)在制定口罩要求方面的拖延。
“我们将永远追逐这一目标，我们将永远落后，病毒将永远跑不过我们。”

伊达尔戈说:“只要我们尽可能少做，并抱最好的希望，我们就会一直追求这件事。”。“我们总是会落后。”
菲尼克斯和迈阿密的市长凯特·加列戈和弗朗西斯·苏亚雷斯有着相似的看法，并在重开努力和各自地区案件增加之间建立了联系。
“毫无疑问...当我们重新开张时，人们开始社交，就好像病毒不存在一样，”苏亚雷斯说。

FDA Commissioner Stephen Hahn won’t confirm Trump’s promises on vaccine timing
Despite President Donald Trump's claims that a COVID-19 "solution" would likely be available "long before the end of the year," a member of the White House coronavirus task force, who leads the agency in charge of approving a vaccine, refused Sunday to offer a timeline for its final development.
"I can't predict when a vaccine will be available," Food and Drug Administration Commissioner Dr. Stephen Hahn said on ABC's "This Week" Sunday, adding, "Yes, we are seeing unprecedented speed for the development of a vaccine. But … our solemn promise to the American people is that we will make a decision based upon the data and science on a vaccine, with respect to the safety and effectiveness of that vaccine."

During a Fourth of July address in Washington on Saturday, Trump struck a more optimistic tone, both on the speed of virus treatment research and development, and on the impact COVID-19 is having upon individuals who test positive.
"We are unleashing our nation's scientific brilliance and we'll likely have a therapeutic and/or vaccine solution long before the end of the year," Trump said, after earlier touting the nation's testing efforts and claiming, without evidence, that "99%" of coronavirus cases "are totally harmless."
Hahn was challenged about the latter assertion by "This Week" co-anchor Martha Raddatz, but refused to join the president in his characterization.
"We have more than 129,000 dead and more than 2.8 million cases, how many cases would you say are harmless?" Raddatz asked.
"What I'd say is, you know, any case, we don't want to have in this country," the commissioner said. "Any death, any case is tragic, and we want to do everything we can to prevent that."
Hahn, a trained radiation and medical oncologist who became FDA commissioner in December 2019,said Thursdaythat he was "cautiously optimistic" about current efforts to develop a coronavirus vaccine, pointing to either "year's end or early next year" as potential completion dates.
Some hesitation among Americans to get a coronavirus shot makes it unclear how much a vaccine would do to halt the pandemic's continued spread. In June, anABC News pollfound that 27% of adults said they would either "definitely" or "probably" not get a vaccine -- a number which Raddatz asked Hahn about on Sunday.
"It is a sizable number and it is concerning and, of course, the issue of vaccines in this country has been around for a number of years," he said, while explaining that the FDA was focused on the "safety" and "efficacy" of a vaccine. "I want to assure the American people that and provide confidence that we're on the job."
COVID-19 cases in the United States continued to surge during the past week, with large states including Arizona, Florida and Texas struggling to contain recent outbreaks.
Local leaders from each of those states also appeared on "This Week" Sunday, and detailed some of the struggles their communities are facing as cases grow and hospitals become overwhelmed.
"What we're seeing is that wishful thinking is neither good economic policy nor good public health policy," said Judge Lina Hidalgo, who serves as the chief executive of Harris County, Texas -- the most populous county in the state, which includes the city of Houston.
Hidalgo lamented that she was stripped of her ability to issue a stay-at-home order by the state government earlier in the year and criticized the delay by Gov. Greg Abbott in instituting face mask requirements.
"We're always going to be chasing this thing, we're always going to be behind and the virus will always outrun us."

"As long as we're doing as little as possible, and hoping for the best, we're always going to be chasing this thing," Hidalgo said. "We're always going to be behind."
Mayors Kate Gallego and Francis Suarez of Phoenix and Miami shared similar sentiments, and drew links between reopening efforts and the increase in cases in their regions.
"There's no doubt that ... when we reopened, people started socializing, as if the virus didn't exist," Suarez said.

"We opened way too early in Arizona," Gallego said. "We were one of the last states to go to stay-at-home and one of the first to reemerge ... I am trying to push people that you need to stay home, and that events with more than 10 people are dangerous."
