The FDA said on Wednesday that some vials of the Pfizer coronavirus vaccine, which began being administered to health care workers earlier this week, are overfilled with doses. These doses, the FDA says, can be used for additional vaccinations, which will help expand the supply.Each vial of the Pfizer vaccine contains five doses. But after the vaccine is thawed and administered, those administering the vaccine discovered it is possible to get a sixth, or even seventh dose from the vaccine.This discovery could potentially allow more health care workers to become vaccinated, extending the supply of the vaccine.“However, since the vials are preservative free, it is critical to note that any further remaining product that does not constitute a full dose should not be pooled from multiple vials to create one,” the FDA said.A Pfizer spokesperson said that each dose of the vaccine must contain .3 mL of the vaccine. The spokesperson said that the amount of vaccine in each vial varies, depending on what type of needles and syringes are being used.According to FDA data, the federal government has allocated 2.9 million doses of the vaccine for the first round of distribution. Those being vaccinated will need to return in 21 days to get a booster in order for the vaccine to be fully effective. 1310

The good news is Americans are getting COVID-19 test results back, on average, a day faster than they were over the summer. The troubling news, according to experts, is that it is still taking three days on average for Americans to find out their COVID-19 status and this is not quick enough to help with contact tracing and quarantine efforts to slow the spread.Researchers from several universities, including Harvard, Northeastern, Northwestern and Rutgers universities, have been collecting data and conducting surveys for months since the beginning of the coronavirus pandemic.“Prompt test results constitute the foundation of a successful COVID-19 containment strategy,” researchers state at the beginning of their paper.Data now shows, of the participants who got a test for the coronavirus in late September, the average wait time was 2.7 days.In early August, the group announced their survey data showed the average wait time nationwide was 4.1 days. More than 30 percent of participants reported, at the time, they didn’t get test results back until four days or longer.The percentage of people getting results within 24 hours is also increasing; the September survey showed 37 percent of people getting results back in one day, compared to 23 percent over the summer.“Rapid turnaround of testing for COVID-19 infection is essential to containing the pandemic. Ideally, test results would be available the same day. Our findings indicate that the United States is not currently performing testing with nearly enough speed,” researchers said.Disparities still exist for Americans who are Black or Hispanic. Although wait times are shorter for these groups as well compared to summer numbers, they are still, on average, a day or more longer than white test takers.In the latest survey, Black Americans reported waiting an average of 4.4 days for results, and Hispanics reported waiting 4.1 days. By comparison, white and Asian Americans reported wait times of 3.5 and 3.6 days on average, respectively.Also troubling for trying to control the spread of the coronavirus, the data shows how many of those who tested positive had some sort of conversation about contact tracing.“Only 56% of respondents who received a positive COVID-19 test say that they were contacted for the purpose of contact tracing,” the survey found.The survey talked to more than 52,000 people across all 50 states and the District of Columbia. 2434

The deadliest shooting in Texas history could have claimed even more lives if it weren't for a local resident who confronted the gunman, and another man who helped chase down the shooter.The resident, whose name has not yet been released, ran out of his house barefoot and exchanged gunfire with the shooter before the gunman sped away in a pearl-colored Fort Explorer. The armed resident then hailed a man across the street and got in his truck, telling him to chase down the gunman."I had to catch the guy. I had to make sure he was caught and at that point the gentleman riding with me said you may have to use your truck to get him off the road and there was no hesitation. It was do everything necessary to make sure that this guy is stopped," the motorist, Johnnie Langendorff said.Hear everything Johnnie Langendorff had to say: At a news conference Sunday night, investigators offered a preliminary timeline of the attack at the First Baptist Church in Sutherland Springs and laid out the role the resident played. Langendorff spoke to CNN on Monday.The gunman entered the small church in the rural town east of San Antonio, firing with an assault weapon at the congregation attending the morning service.A local resident grabbed his own rifle and engaged the gunman, said Freeman Martin, the regional director of the Texas Department of Public Safety."The suspect dropped his rifle, which was a Ruger AR assault-type rifle and fled from the church," said Martin."What do you say to the man who stepped up when he heard the gunshots? I'd say he's a hero," Wilson County Sheriff Joe Tackitt Jr. told CNN's Chris Cuomo on Monday. "I don't think there's any question about that. Had he not done what he did, we could have lost more people."He was just driving byLangendorff said he was driving by the church on the way to his girlfriend's house when he saw gunfire between the shooter and the armed resident.Langendorff told CNN that both men had weapons drawn."There was exchange of gunfire. It lasted just a few seconds, and the shooter got in his vehicle and took off," he said.The armed resident opened Langendorff's door, said the gunman shot up the church and urged the driver to step on it."We got to chase him," the man said, according to Langendorff. He said he answered, "Let's go."They gave chase in his truck for 11 miles and called police dispatch to tell them where they were and in what direction they were headed. The chase was 10 to 12 minutes long."The vehicle was in sight and I was picking up, getting closer and closer to it. We hit about 95 (mph) ... trying to catch this guy until he eventually lost control on his own and went off into the ditch," Langendorff told CNN affiliate KSAT."The gentleman that was with me got out and rested his rifle on my hood and kept it aimed at him (the shooter), telling him to get out. There was no movement, there was none of that. I just know his brake lights were going on and off, so he might've been unconscious from the crash or something like that. I'm not sure."Langendorff felt the suspect, who crashed his vehicle near the county line, "just gave up."When police arrived about five minutes later, they approached the suspect's vehicle and found the gunman inside dead of a bullet wound. He was later identified as Devin Patrick Kelley.Asked by CNN what he was thinking at the time, Langendorff said, "Nothing. Get him." Why? "Because that's what you do, you chase a bad guy."The shooting was a horrific tragedy, Langendorff said, but he hopes the families of the victims can sleep better knowing the shooter "was taken care of."And he has no regrets about throwing himself into such a dangerous situation."I hope that everyone affected is able to rest a little better knowing that this guy, he'll never breathe again. It doesn't serve it justice completely. But he won't hurt anyone else ever."Bravery seen at another church shootingLangendorff praised the resident for his quick action and called him "very much a hero."He emerged barefooted, grabbing his gun before he grabbed his shoes."He did absolutely the right thing, which was try to take him down at the scene," he said.The shooting at the church claimed 26 lives.Investigators "are continuing in their efforts as they put all the pieces of a very complex puzzle together to try to provide their community all the answers they need and deserve," Texas Gov. Greg Abbott said.It's the deadliest mass shooting in Texas history -- and the fifth deadliest in modern US history.The Sutherland Springs resident's actions echoed another man's act of bravery during a different church shooting earlier this year in Antioch, Tennessee.As the service at the Burnette Chapel Church of Christ was ending on September 24, a gunman -- whom police identified as 25-year-old Emanuel Kidega Samson -- entered the church with a pair of pistols and started firing. An usher at the church, Robert Engle, sprang into action -- struggling with the suspect, even as he was being pistol-whipped, police said."Mr. Samson didn't expect Mr. Engle to encounter him, to struggle with him, to try to stop the shooting," said Don Aaron, the spokesman for the Metropolitan Nashville Police Department.During the altercation, the gunman accidentally shot himself in the chest with his own weapon, police said.When the gunman fell, Engle, despite his head injuries, ran to his car and came back with a pistol of his own, police said.Engle, who has a permit for a handgun, then made sure Samson stayed on the ground until officers arrived, Aaron said.  5564

The coronavirus vaccine has been administered to 1 million Americans in the last 10 days, the CDC reported on Wednesday.The first vaccinations were administered to Americans early last week after Pfizer’s coronavirus vaccine received an emergency use authorization. Pfizer said last week that it had distributed 2.9 million doses of the vaccine throughout the United States.Earlier this week, Moderna’s coronavirus vaccine candidate began being administered to Americans.So far, there have been over 9.4 million doses of the vaccine distributed throughout the US. Getting them administered is taking some time.Although 1 million vaccinations is a significant milestone, it is a fraction of the vaccinations needed to stop the spread of the virus. The first round of vaccinations are intended for 24 million Americans who work in health care settings or who live or work assisted living facilities. The next step will be to vaccinate 21 million Americans over the age of 75 and 30 million front-line workers, such as teachers, first responders and grocery store employees.“While we celebrate this historic milestone, we also acknowledge the challenging path ahead,” CDC director Robert Redfield said in a statement. “There is currently a limited supply of COVID-19 vaccine in the U.S., but supply will increase in the weeks and months to come. The goal is for everyone to be able to easily get vaccinated against COVID-19 as soon as large enough quantities are available.”Those who have received their first dose of the vaccine will need to return for a booster in 21 to 28 days, depending on the vaccine administered. 1625

The Georgia Democratic Party and gubernatorial candidate Stacey Abrams' campaign filed a lawsuit in federal court Sunday asking for rejected absentee ballots and provisional ballots to be counted in the Georgia governor's race.The lawsuit challenges the rejection of more than 1,000 absentee ballots for missing information or mismatching information, like birth dates or addresses.The lawsuit also seeks relief for voters whose provisional ballots were rejected in Gwinnett and Dekalb counties, which are in the Atlanta metro area, because they are registered in a different county.CNN has not projected a winner in the race.Republican candidate Brian Kemp currently leads Abrams with 50.3% of the vote. If Kemp's share dips below 50%, the race automatically goes into a run-off on December 4, even if Kemp is the top vote-getter. For now, Kemp's lead stands at nearly 59,000 votes. 891
