The University of Washington’s Institute for Health Metrics and Evaluation has been issuing frequent projections since March in an attempt to model the spread and impact of the coronavirus across the world.The models have been used by the CDC and White House coronavirus task force in an effort to better understand the potential number of deaths the coronavirus could cause.On Friday, the model added a new variable, one that could cause a steep decline of coronavirus deaths throughout the US. The IHME’s newest model, which predicts the number of coronavirus deaths in the US through the end of March, is now weighing the potential impact of vaccines on the virus.For those hoping for an immediate drop in hospitalizations and deaths caused by the coronavirus as soon as vaccinations begin later this month might be disappointed. The IHME's model shows the initial batch of vaccinations will have a relatively muted effect on deaths and hospitalizations initially. While by April 1, much of the general US population will likely not be fully vaccinated, many in the high-risk category should expect to vaccinated by then. How fast they get vaccinated will play a role in determining the number of coronavirus deaths in the US.As of Friday evening, there have been over 278,000 coronavirus-related deaths reported throughout the US, per Johns Hopkins University data. Without any vaccines reaching Americans, the IHME’s model projects a total of 548,000 would die from the coronavirus through April 1, meaning 270,000 deaths between now and then.If COVID-19 vaccines are distributed at expected levels, 9,000 lives would be saved by April 1, reducing the number of deaths between now and then to 261,000. But a rapid vaccine rollout – one that would vaccinate the high-risk population and begin to vaccinate the general population by the spring -- would result in 250,000 deaths between now and April 1.“Mass scale-up of vaccination in 2021 means we have a path back to normal life, but there are still a few rough months ahead,” said Dr. Christopher Murray, IHME director. “We must be vigilant in protecting ourselves at least through April, when, as our projections indicate, vaccines will begin to have an impact.”In the meantime, Murray says universal mask wearing and social distancing will save more lives than a potential vaccine in the next four months.“Especially in the Northern Hemisphere, it’s crucial for governments to impose or re-impose mandates that limit gatherings and require masks. Where the winter surge is driving spikes in infections, there will be many people who can still become infected and possibly die before the vaccine is fully rolled out,” said Murray.To see the IHME’s state-by-state projections for deaths, hospitalizations and cases, clickhere. 2790

The Washington Post has settled a libel lawsuit with Kentucky high school student Nicholas Sandmann, who was at the center of a viral video controversy in 2019.Sandmann sued several news media outlets after their coverage falsely painted his as a racist, wearing a ‘Make America Great Again’ hat during an interaction with a Native American activist near the Lincoln Memorial in Washington D.C. Judge William O. Bertelsman previously dismissed the lawsuit, but later reinstated the case, after he reviewed an amended complaint.On Friday, Sandmann celebrated the settlement on Twitter. 592

The walk to school turned terrifying for a Rochester, Michigan teen who says he was shot at after he stopped to ask for directions.Fourteen-year-old Brennan Walker missed the bus and tried to walk to school, but got lost after he couldn't remember the route.The freshman wasn't hit, as the shot missed him as he ran away.The situation began when Walker's alarm didn't go off. After missing his bus, he thought he could walk the roughly 4 miles to school.Once he became lost, he stopped at a home and knocked."I knocked on her door a few times and she came down yelling at me before I could say anything and she thought I was trying to break into her house," he said. "I was trying to explain to her that I wanted to get directions to go to my school. I told her no, I go to Rochester High I’m just looking for directions to Rochester High."Walker and his mother, Lisa, say the security video from the home shows the woman then yelled for her husband."The man of the house came down, pretty much just grabbed the shotgun to shoot at my son," says Lisa Walker."I saw it. I saw him holding it like this through the window and I guess I put my hand up, I don’t really remember, and I started to run," Brennan Walker says. "I looked back behind me I saw him aiming at me and I turned back. I turned back and I heard the gunshot. And I tried to run faster."The man has been taken into police custody."If someone is running from your house and chase them outside and shoot at them, you’re going to have criminal charges coming from us," Oakland County Sheriff Michael Bouchard said.Both Walker and his mother believe race was a factor in the incident."After watching the video and hearing the wife say 'why did these people choose my house' I knew it was racially motivated. I don't know what other these people she could possible have been talking about. He was by himself," Lisa Walker said."I didn’t want to believe that that type of stuff could happen here," said Brennan, who said he is just trying to process the shock of what happened."I don't, I don't know how you process getting shot at for asking for directions," he says. 2159

The Transportation Security Administration (TSA) screened the highest number of travelers on Sunday since the start of the pandemic as more than a million Americans traveled home following the Thanksgiving holiday.The TSA screened 1.2 million passengers on Sunday, marking its highest total since March 16 — just days after President Donald Trump delivered a primetime address announcing travel restrictions to Europe as COVID-19 began to spread in the U.S. While TSA screening numbers aren't representative of all travel throughout the U.S., the number gives officials an idea of how many people boarded an airplane in the U.S. in a given timeframe.Despite the uptick in travelers, the amount of Americans traveling following Thanksgiving was nowhere near the amount that traveled on the Sunday following Thanksgiving in 2019 — on that day, TSA screen 2.9 million Americans.The uptick in travel comes despite warnings from the CDC against traveling for Thanksgiving amid a spike in COVID-19 cases. Top ranking health officials are urging anyone who traveled to attend a Thanksgiving gathering to get tested for COVID-19 even if they do not have symptoms.On Sunday, Dr. Deborah Birx — a member of the White House coronavirus task force — said anyone who attended a Thanksgiving gathering over the weekend should "assume" they have COVID-19 and take precautions against spreading the virus in the coming weeks.The U.S. has seen more than 4 million people become infected with the virus in November alone — a number that represents 30% of all cases recorded in the country since the pandemic began.Last week, Dr. Anthony Fauci — the U.S.'s leading infectious disease expert — warned that the U.S. could see a "spike superimposed on a spike" in cases in the weeks after Thanksgiving if Americans continued to travel. 1821

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
