The Senate on Wednesday will hold a hearing regarding the safety of vaccines, which will feature appearances by Surgeon General Dr. Jerome Adams and National Institutes of Health Director Dr. Francis Collins.The hearing, hosted by the Senate HELP Committee, will discuss the role of vaccines in preventing infectious disease outbreaks and protecting public health.Wednesday's hearing will also include information on a potential COVID-19 vaccine.Top U.S. health experts like Dr. Anthony Fauci say they are cautiously optimistic that there will be enough evidence to grant Emergency Use Authorization to top vaccine candidates by the end of 2020. However, recent polls indicate that some Americans remain skeptical about vaccines.A recent CBS News poll indicates that just 21% of American voters would receive a COVID-19 if one were made available at no cost. That's down from about 30% earlier this year. Two-thirds of those polled say they feel a vaccine would be "rushed" if a vaccine were made available this year.Fauci has said that if a potential vaccine is 75% effective against the virus, it still may not be effective in promoting inoculation levels necessary for "herd immunity" in the U.S. due to Americans' ongoing skepticism about vaccines.Nine vaccine makers banded together to sign a pledge on Tuesday to say that they will not seek Emergency Use Authorization for their vaccine candidates until scientific methods prove they are safe for widespread use. 1476

The U.S. has surpassed another bleak marker in the COVID-19 pandemic, as the country has reached 10 million confirmed cases of the virus, according to a database kept by Johns Hopkins.The milestone comes just hours after global cases surpassed 50 million, meaning about one out of every five people around the world diagnosed with the virus since the pandemic began has been diagnosed in the U.S.At least 237,000 Americans have died of the virus since the pandemic began. The U.S. continues to lead the world in both total cases and in deaths linked to the virus.The U.S. surpassed its 10 millionth case as the country deals with a disturbing spike in infections ahead of the winter months. The country surpassed 120,000 new cases in a single day three times last week, obliterating previous records. Prior to last week, the most confirmed cases the U.S. had seen in a single day was 102,000.The U.S. has recorded a million new cases of COVID-19 in the last 10 days alone. The country surpassed the 9 million case plateau on Oct. 30.In addition to the spike in cases, hospital resource use is also on the rise, and deaths linked to the virus are up slightly in recent days, though the death rate is not near what it was in March and April. Johns HopkinsHealth experts have warned that the U.S. is currently in a perilous position in the pandemic, with transmission rates as high as they have ever been as Americans move social gatherings indoors for winter months.In a memo last week, Dr. Deborah Birx — a member of the White House coronavirus task force — warned that the country is entering "the most deadly and concerning" phase of the pandemic.Late last month, Dr. Anthony Fauci — a member of the White House coronavirus task force and the county's top expert on infectious diseases — warned that the U.S. was in for a "whole lot of pain" if things didn't change soon.The U.S. did get some good news in the pandemic on Monday, as Pfizer announced that its vaccine candidate has been 90% effective in promoting immunity against the virus. However, even if the vaccine were to get FDA approval in the next few days, it would still take several months for most of the country to be vaccinated — and officials fear that vaccine skepticism could keep immunity levels below the threshold to stifle the virus. 2314

The Transportation Security Administration is considering eliminating passenger screening at more than 150 small and medium-sized airports across the US, according to senior agency officials and internal documents obtained by CNN.The proposal, if implemented, would mark a major change for air travel in the US, following nearly two decades of TSA presence since the terrorist attacks of September 11, 2001, and comes as the Trump administration has stepped up screening measures for items such as laptops and tablets.Internal documents from a TSA working group say the proposal to cut screening at small and some medium-sized airports serving aircraft with 60 seats or fewer could bring a "small (non-zero) undesirable increase in risk related to additional adversary opportunity."The internal documents from June and July suggest the move could save 5 million annually, money that could be used to bolster security at larger airports.According to the proposal, passengers and luggage arriving from these smaller airports would be screened when they arrive at major airports for connecting flights instead of the current practice of joining the already screened population at the larger airport. The high-volume airports have greater capacities and more advanced security measures than smaller locations, the documents say.CNN terrorism analyst Paul Cruickshank said it was "stunning that this is even seriously being considered.""Al Qaeda and ISIS still regard aviation as a priority target -- that includes aircraft where you have fewer than 60 people on board," he said. "They would see that as a way to hit the headlines. They would see that as a way to inflict severe economic damage on the United States. If you have an aircraft of 50 or so people being blown out of the sky there is going to be a great amount of panic and there will indeed be significant economic reverberations, and of course significant loss of life.""This is so dangerous," a TSA field leader at a large airport said. The individual is not authorized to discuss the matter publicly.Two senior TSA officials, who asked not to be identified, expressed serious national security concerns over the proposal. They said the idea was explored as far back as 2011 and has been resurrected. The documents referred to some 150 small airports in addition to some midsize ones. TSA currently screens passengers at 440 airports, according to its website.The working group determined that the policy change would affect about 10,000 passengers who are screened by 1,299 TSA employees daily, which amounts to about 0.5% of the people who fly out of US airports on any given day. The report does not list specific airports that could be affected by the policy change.TSA spokesman Michael Bilello said the study reflects a recurring debate within the agency about its legal requirements."This is not a new issue," he said via email. "The regulations which established TSA does not require screening below a certain level, so every year is 'the year' that TSA will reconsider screening." Bilello did not respond to a request for the text of the regulations.The two TSA senior officials said the level of activity around the proposal this year -- the formation of a working group to conduct a risk and cost analysis -- mean this is more than an annual exercise.The documents said a TSA working group of 20 people, including a representative of the agency's administrator's office, met on June 21 to examine the potential risks of the policy change. An internal TSA memo dated July 17 from TSA Director of Enterprise Performance and Risk Strategy Jerry Booker to the TSA administrator's chief of staff, Ha Nguyen McNeill, outlines the group's findings. It contains no formal recommendation. 3761

The White House on Tuesday said the Justice Department should consider a criminal prosecution of former FBI Director James Comey, claiming he had leaked privileged information to the press and offered false testimony to Congress."It's something they should certainly look at," press secretary Sarah Sanders told reporters when asked whether the administration should prosecute Comey. She acknowledged that it was "not the President's role" to determine which criminal investigations are taken up by the Justice Department.The question arose as Sanders defended Trump's decision to fire Comey earlier this year, a choice Trump's former chief strategist called a mistake this week.Speaking to "60 Minutes" on CBS, Steve Bannon called the Comey decision the worst mistake in "modern political history." 812

The World Health Organization updated its guidelines on mask-wearing Tuesday, recommending that anyone over the age of 12 wear a mask indoor and outdoor and inside your home if it's ventilated poorly.The updated guidelines come as COVID-19 cases continue to sore in America. On Wednesday, 180,083 new cases were reported, according to data from Johns Hopkins University.According to the guidelines, in areas where COVID is spreading, WHO recommends that anyone over the age of 12 wear masks in shops, shared workplaces, and schools if they can't maintain a distance of more than 3-feet between others.They also recommend masks be worn when people visit your home if there's not adequate ventilation, or you can't be more than 3-feet or more from each other.The WHO said on top of wearing a mask, other precautions such as washing hands, avoiding touching your face, having adequate ventilation if indoors, testing, contact tracing, quarantine, and isolation should also be taken."Together, these measures are critical to prevent human-to-human transmission of COVID-19," WHO said.In areas of COVID-19 spread, the organization said healthcare workers should take part in "universal masking" in health care facilities, meaning they should wear an N95 respirator mask throughout their entire shift, including when caring for other patients.The advice applied to visitors, outpatients, and common areas such as cafeterias and staff rooms, but added administrative staff does not need to wear a mask if they are not exposed to patients.The organization also recommended that people who do vigorous physical activity should not wear masks, citing some associated risks, particularly asthma.For children, the WHO recommends children up to 5-years-old should not wear masks for source control. They added that children between the ages of 6 to 11-years-old should only wear masks if "a risk-based approach is applied.""Factors to be considered in the risk-based approach include intensity of COVID-19 transmission, child’s capacity to comply with the appropriate use of masks and availability of appropriate adult supervision, local social and cultural environment, and specific settings such as households with elderly relatives, or schools," the organization added in its guidelines. 2285
