A final analysis of a COVID-19 vaccine candidate produced by Pfizer and BioNTech shows that the drug is 95% effective in preventing the coronavirus, and the companies say they hope to apply for Emergency Use Authorization within "days," the company reported Wednesday.The announcement is an improvement from an initial analysis released by the company just over a week ago that showed the drug to be 90% effective. Those results were released when it had been confirmed that 94 participants in the trial who received a shot had contracted COVID-19, and only 10% of those participants who contracted the virus had actually received the vaccine. Updated information now shows that 170 people who participated in the trial have contracted COVID-19, which crosses the threshold for final analysis. Of those participants, 162 received a placebo shot. Of the 20,000 participants who received the vaccine, just one has developed a severe case of COVID-19. The other seven people who received the vaccine and caught the virus are only experiencing mild symptoms.Pfizer also added that the vaccine has proven to be 94% efficient in older people — a welcome sign, given that the virus tends to present more severe symptoms in elderly patients.Pfizer's trial included about 40,000 participants, half of which received the vaccine, and the other half which received the placebo. The vaccine requires two shots, which need to be taken 28 days apart.The company added that there have been no safety concerns with the vaccine. In a randomized survey of 8,000 participants, only 2% reported suffering severe fatigue, and only 4% reported suffering severe headaches. Those who say they suffered side effects only experienced them briefly after vaccination.Wednesday's announcement means Pfizer is on track to shatter records for vaccine development, a process that typically takes several years.Pfizer and BioNTech already have their vaccine candidate in production, meaning it will be ready for distribution as soon as the Food and Drug Administration grants Emergency Use Authorization.Pfizer's announcement comes days after an initial analysis of a Moderna-produced vaccine was also shown to be 95% effective. Several other companies also have a COVID-19 vaccine in the works, something that health officials say is important for logistics and safety. 2347

A line wrapped around the corner is a familiar sight to Pastor Bernard Taylor. Families in need know when they come to this Brooklyn church, they’ll be met with open arms and with a helping hand.“It means a lot, a whole lot for the community,” said Maureen Waters, who drives more than an hour to get food and supplies for herself and her grandkids.“We feed up to 100 and 5,000 people per year, and the number, quite naturally, is going to grow due to the pandemic,” said Pastor Taylor.More people need fresh food, school supplies, and clothing than ever before, and the Open Door Church of God in Christ provides it all.“We’re here rain, sun, hail, snowstorm, we are here,” said one volunteer. However, the pandemic is just as threatening to the church as it is to the community.“Some people have lost their homes. Some people can't make ends meet, and some people are really struggling,” said Taylor. “And if they're struggling, we struggle, because it's a trickle-down effect. If they're not receiving, then they can't give."Because of the pandemic, this church, like so many across the country, has shifted to online services. The empty pews often translate into near-empty collection baskets, leaving the church’s staff and its programs in a tough spot.“The payroll department has suffered because we don't have no streams of income to really satisfy or to cover that budget,” said the pastor. “It’s been many times that I’ve said, ‘Well I don't know what we're going to do.’”The business behind many churches in the United States is in for a long recovery.The Barna Group found 1 in 3 people who regularly attended church have stopped watching online services, leaving fewer involved parishioners ready to donate.A leader with Lifeway Research, a group studying churches, estimates 5% of churches will close permanently before the end of the year because of COVID-19. That number is five times higher than typical yearly closures.The question of a church’s survival made even heavier by the loss of life many churches have seen. For the Open Door Church of God in Christ, 19 church members have passed away during the pandemic.“We had some ushers that passed away. That was essential. Some nurses that passed away, and just so many members that I loved so much, and I miss each and every one of them,” said Taylor.Many of those church members also substantially supported the church’s finances. Their loss has caused such a ripple effect; Pastor Taylor had to step in to help his congregation.“I had to put in ,000 of my own personal money at one time just to see the payroll get taken care of, and I don't look for it back. I give it from my heart, and whatever I have to do, I give my last to make sure people have,” he said.To make sure this church could survive, a group called Churches Helping Churches also got involved, donating ,000 to this church and others across the nation that offer their community more than a house of worship.“I’m not working, so I’m glad I can come here,” said Maureen Waters. “I’m not hungry anymore, so it’s good.”Pastor Taylor fears if his church can’t serve the community, they will lose something greater than a place to gather."What's at stake is people lose hope, and we don't want people to lose hope," he said. "We want people to always know that they can depend on what they always depend on and that is the church being the church."Pastor Taylor he has a plan to make sure his business of helping others stays in business for good.“We have to make sure that we do three things. Number one, we have to adjust. We have to adapt, and then, we can overcome."Adapting to a life of coming together while staying apart to overcome the hunger in the community—in both body and soul.If you would like to help a local church that may be forced to close its doors, you can donate to Churches Helping Churches. 3861

A chalk art controversy at Cleveland State University is getting national attention online.A group of students created a memorial for the victims of 9/11 on the sidewalks outside the CSU student center. On the morning of the somber anniversary, the university's maintenance crew removed the murals with a power washer.Now CSU and the head of its maintenance department are getting blasted on social media. The comments and reaction have not been good.But what is being lost in the online outrage is that this form of expression is actually not allowed on campus.CSU sophomore Tiffany Roberts pointed out the streaks of color that remain on the sidewalk outside the CSU Student Center Wednesday."So right here, we had two twin towers and it said 'pause,'" said Roberts.She was standing near her project on the morning of Sept. 11 when a crew showed up with a power washer."It was really disheartening to see all of our hard work kind of wash away like that," said Roberts.Roberts, along with nearly a dozen of her classmates, are members of a conservative campus group."Our whole intention was to just honor those people," said Donato Nunez.On Sunday night, they used chalk to pay their respects to the victims of 9/11."I looked through the handbook to make sure it was OK for me to chalk on campus," said Roberts.Roberts told WEWS she didn't see anything about chalk."The only thing I found was that you are not allowed to attach anything to the sidewalks or the pavements," said Roberts.Monday morning, the CSU Director of Facilities Management, who also happens to be Muslim, sent a crew out to wash the artwork away.A handful of conservative websites, along with social media, quickly erupted with outrage, alleging that it may have been politically motivated. "Absolutely disgusted by this!" wrote one Facebook user. "People can desecrate the American flag, people can refuse to stand for the national anthem, they organize Rally's to keep others from using the freedom of speech, and all that's ok... Students work hard in drawing an American flag on Sept 11th, it gets washed away, on the order of an Islamic man, and that's ok! Exactly what's wrong with this country!"Now some members of the conservative campus group acknowledge the rumors got out of hand by social media users who were unfamiliar with the facts.  "It just looks so bad, and we didn't want that," said Nunez.Cleveland State said this has nothing to do with religion and it does not allow students to use chalk to express themselves on campus. The crew was just doing its job and following protocol."People were trying to make us look bad, they were just going off facts they didn't know," said Nunez.Roberts met with the VP of Student Affairs hours after the murals were washed away.“At the end of the meeting we both agreed upon that the handbook needs to be changed, and that organizations need to be more aware that this is something that is not allowed on campus," said Roberts.Cleveland State issued the following statement: 3057

A group of 14 mayors from across the U.S. are calling for federal law enforcement and military to stop their deployment to cities in response to protests."We urge you to take immediate action to withdraw your forces and agree to no further unilateral deployments in U.S. cities," said the mayors' letter to Attorney General William Barr and Homeland Security Chad Wolf.The letter was signed by the mayors of Denver, Portland, Seattle, Atlanta, Chicago, Washington D.C., Kansas City, Boston, Philadelphia, Los Angeles, San Jose, Oakland, Tucson and Sacramento.D.C. Mayor Muriel Bowser posted the letter on Twitter on Tuesday night.Portland Mayor Tom Wheeler has said that federal officers are not wanted in the city, where protesters have clashed with agents in recent weeks as nightly protests have happened in the wake of George Floyd's death.Federal authorities have reportedly driven in unmarked cars in the cities and detained protesters.The mayors' letter called the deployment of federal forces "unacceptable and chilling.""In Portland, federal forces have used significant force against protesters on a nightly basis, including shooting one individual in the head with a munition, reportedly fracturing his skull," the mayors' letter said. "Others 'snatched' an individual from the street without proper identification and placed him in an unmarked vehicle. These are tactics we expect from authoritarian regimes — not our democracy."The FBI's Joint Terrorism Task Force worked the Denver protests shortly after Floyd's death, announcing they would "apprehend and charge violent agitators hijacking peaceful protests," though federal authorities' presence has mostly been limited in Denver.Also, on Wednesday, Colorado Sen. Michael Bennet joined Oregon senators Jeff Merkley and Ron Wyden and Connecticut Sen. Chris Murphy in introducing proposed legislation to block the Trump Administration from deploying federal forces "as a shadowy paramilitary against Americans."“The Trump Administration’s decision to send unidentified federal agents into Portland to terrorize protesters who are exercising their First Amendment rights only sows more fear and division,” Bennet said in a news release. “America is not a battlespace. This should not be happening in a healthy democracy, and this legislation aims to prevent our federal government — including the president — from using these tactics.”Colorado Gov. Jared Polis on Tuesday said "we have no indication or reason to believe" federal forces are being deployed to Colorado, where some protests have continued, both in response to Floyd's death and the death of Elijah McClain in Aurora."Based on what I've read in the press, I have concerns this is a violation of people's rights," Polis said. "I will be following this in the press, and I would be alerted if this were to occur in Colorado."This story was originally published by Ryan Osborne at KMGH. 2919

A former Google engineer is accusing the company of firing him after he spoke out about incidents of racism, sexism and harassment.Tim Chevalier is suing Google for retaliation, wrongful termination and failure to prevent discrimination and harassment, according to a lawsuit filed in San Francisco on Wednesday.Silicon Valley -- and Google in particular -- has been shaken by fierce debates over diversity issues. Highly charged arguments between Google employees have at times burst into public view as the company wrestles with how to address the concerns.The lawsuit by Chevalier, who identifies as transgender and disabled, claims Google's culture is discriminatory. He alleges that some employees use the company's internal social-networking and messaging systems to belittle and bully women, people of color and LGBTQ colleagues."Chevalier pushed back on the online bullying he and others were experiencing, using the same internal messaging systems to try to educate his employer and coworkers on how to change Google's working conditions to be inclusive and supportive of underrepresented minorities, such as himself," the lawsuit says.His lawsuit alleges that rather than trying to address the concerns he was raising about other employees' behavior, Google fired him in November, citing the political nature of his posts."It is a cruel irony that Google attempted to justify firing me by claiming that my social networking posts showed bias against my harassers," Chevalier said in a statement provided by his lawyers. "The anti-discrimination laws are meant to protect marginalized and underrepresented groups -- not those who attack them."Google spokeswoman Gina Scigliano declined to comment directly on Chevalier's allegations. She said that lively debate is important to Google's culture, but that there are limits."All employees acknowledge our code of conduct and other workplace policies, under which promoting harmful stereotypes based on race or gender is prohibited," Scigliano said in a statement. "This is a very standard expectation that most employers have of their employees. The overwhelming majority of our employees communicate in a way that is consistent with our policies. But when an employee does not, it is something we must take seriously. We always make our decision without any regard to the employee's political views."In the lawsuit, which was first reported by tech news site Gizmodo, Chevalier alleges that some Googlers would call coworkers "immoral" because of their sexual orientation. Employees also questioned the competency of women and minorities on internal message boards, he said."Company social networking forums can be incredibly useful, but employers have an obligation to prevent them from becoming a cesspool of bullying and harassment," David Lowe, an attorney for Chevalier, said in a statement. "Firing the employee who pushed back against the bullies was exactly the wrong step to take."Debates inside Google about diversity issues erupted in August when one of the company's senior engineers at the time, James Damore, published a controversial memo claiming women are underrepresented in technology because of psychological and biological differences, not sexism.In his memo, Damore claimed to "value diversity and inclusion," but he took issue with Google's approach, which he described as overly political and alienating to "non-progressives."Damore, who was fired over the controversy, and another former Google engineer, David Gudeman, are suing the company, alleging that it discriminates against white men and conservatives.Chevalier waded into the internal debates over Damore's memo last summer, according to his lawsuit. It says that in September, a Google human resources representative spoke with Chevalier about some of his emails and posts on internal forums regarding the memo and other politically charged subjects.Google is also facing a gender-pay lawsuit claiming the company paid women less than their male counterparts.  4016
