Dr. Anthony Fauci warned Sunday that even if a COVID-19 vaccine becomes available, it still may not yield herd immunity.In an interview with the Aspen Institute on Sunday, Fauci — the U.S.'s top infectious disease expert — said he would settle for a vaccine that is between 70 and 75% effective."I doubt seriously that any vaccine will ever be a hundred percent protective. The best we've ever done is measles, which is 97 to 98% effective. That would be wonderful if we get there. I don't think we will," Fauci said. "I would settle for 70, 75% effective vaccine because that would bring you to that level of would-be herd immunity level."But a CNN poll says one-third of Americans do not plan to get a vaccine if it becomes available. Fauci said Sunday that if those figures hold true and a potential COVID-19 vaccine is only 75% effective, the U.S. population would not reach the herd immunity threshold that would kill the virus."That's one of the reasons why we have to make sure we engage the community as we're doing now to get community people, to help us for people to understand that we are doing everything we can to show that it's safe and that it's effective," Fauci said. "And it's for the good of them as individuals and in society to take the vaccine."Three coronavirus vaccines are expected to be studied in large-scale clinical trials in the next three months.Herd immunity comes when a sufficient portion of a population is immune to an infectious disease. That can come either come through prior illness or vaccination, making the disease unlikely to spread further. 1594

During a phone interview with Fox Business on Thursday morning — his first TV interview since contracting COVID-19 — President Donald Trump said that while he hasn't been tested for the virus recently, his health is continuing to improve."I'm essentially very clean," Trump told Fox Business anchor Maria Bartiromo.Trump added that he would be tested again for the virus "very soon" to determine if he's still infected.The President also added that he doesn't "feel" like he could spread the virus to others."No, I don't think I'm contagious. I don't think I'm contagious at all," Trump said.According to the CDC, people infected with COVID-19 can still spread the virus, even if they are asymptomatic. The virus is typically active in humans for about two weeks, though it can last longer.The White House has refused to report when Trump last tested negative for the virus, but Trump announced his positive test on Friday, meaning he may be contagious for about another week.White House chief of staff Mark Meadows said on Wednesday that Trump would like to begin working from the Oval Office and that White House staff would implement safety precautions to make that happen. The CDC recommends those who are infected with the virus remain quarantined.Trump also falsely said Thursday that he's now "immune" to COVID-19."Remember, when you catch it, you get better, and then you're immune, you know?" Trump said. "As soon as everything goes away for me, you're immune."There are several documented cases where people who had previously contracted COVID-19 caught it again — though they suffered less severe symptoms. The CDC says that estimates indicate that COVID-19 antibodies make a person immune for about three months.During his Thursday interview, Trump said he assumed earlier this year that he might catch the virus at some point."But I did look at the numbers say I'll probably catch it, and I'll get better," Trump said. "And that's what happened."Despite the risks, Trump said he needed to continue to face the public because he had to be a "leader." As an example, he said he continued to meet with the families of soldiers who had been killed in action, even though social distancing was not always observed at those ceremonies."They're telling me these stories, and I can't say, 'Back up, stand 10 feet.' I just can't do it. I went through like 35 people and everyone had a different story," Trump said. "They come within an inch of my face sometimes, they want to hug me and they want to kiss me. And they do. I'm not telling them to back up."Trump said Thursday that he believed he contracted the virus at a September ceremony at the White House where he nominated Judge Amy Coney Barrett to the Supreme Court."As far as the White House is concerned, somebody got it in — it was a day of celebration with Notre Dame, etc. etc. Somebody got in and people got infected, whether it was there or something else.," Trump said.Finally, Trump touted the COVID-19 therapeutic drugs he took while in the hospital, falsely calling them "cures." He added that drugs made by Regeneron and Eli Lilly would be granted Emergency Use Authorization (EUA) by the FDA to treat the virus."You take it, and it beats the hell out of it. I'm telling you, I could have walked out of there 24 hours after I went in. I didn't even have to go in, frankly. I think it would have gone away."Trump was referring to REGN-COV2, a monocolonal antibody therapy the clones the strongest antibodies from COVID-19 patients. Regneron formally requested EUA for the drug on Wednesday.Regeneron says it has approximately 50,000 doses of the drug on hand, but could have up to 300,000 doses "within the next few monts," according to CNBC.While the drug has been effective in treating COVID-19, there is no "cure" for the virus. Health experts expect several COVID-19 vaccines to be approved by the end of 2020 and be widely available by the middle of 2021. 3940

Dr. Sean Conley, President Donald Trump’s physician, said on Monday that Trump has tested negative for the coronavirus on consecutive days.As Conley’s statement was released to the media on Monday, Trump was setting off for a Florida rally, marking his first voyage out of the White House since returning to the complex last Monday following a three-day stay Walter Reed Medical Center.Previously, Conley said that Trump was no longer infectious, but would not confirm if Trump had tested negative.Meanwhile, White House Chief of Staff Mark Meadows dodged questions earlier on Monday on whether Trump had tested negative. Trump held his first public event since his coronavirus infection on Saturday, speaking to hundreds of supporters from the White House balcony.The CDC says that for most coronavirus patients, they are no longer contagious after 10 days, but the isolation period may need to be extended to 20 days depending on the severity of the infection. Trump announced he was positive for the virus in the early morning hours of October 2.With Trump no longer considered contagious by doctors, he is planning on resuming an active campaign schedule with events planned in swing states every day through Thursday. 1230
