The excitement of two COVID-19 vaccines with more than 90 percent efficacy is undeniable.In November, both Pfizer and Moderna announced its scientists had developed vaccines with efficacy at or near 95 percent, but scientists are warning these vaccines are not the "silver bullet" to ending the pandemic.“We don’t want to give the public the impression that there’s an emergency use authorization and these vaccines become available in a small amount in December and we can go back to our pre-pandemic behavior,” said William Moss, executive director of the International Vaccine Access Center at Johns Hopkins.In June, the FDA released its vaccine guidelines, saying it would consider emergency use authorization for any vaccine testing with at least 50 percent effectiveness, so there is a reason for celebration, according to Moss, but only after certain questions about the vaccine are answered.Dr. Anthony Fauci has said the initial vaccines will prevent symptoms in those who become infected, rather than kill the virus itself. Moss says that means immunized people might be able to spread COVID-19 to others.He also wonders how long immunization will last. One year? Three years? Will booster doses be needed? They're all careful considerations that will only emerge once one is put into play, according to Moss.“It’s obviously tragic that the [COVID] cases are occurring that quickly, but it does help a vaccine trial because otherwise you just have to wait that much longer for samples to come in,” said Moss.The vaccine process has innovated how scientists and researchers approach these types of situations, however, according to Moss.In traditional vaccines, a small dose of the virus is injected into the body so the immune system can create antibodies. In the COVID-19 vaccine, though, both Moderna and Pfizer have used what is called messenger RNA (mRNA) where the virus’ genetic code is injected into the body so it can instruct cells on what antibodies to produce. Scientists say this way is faster, safer, and can create a stronger immune response as people are not exposed to the virus.“I suspect that if this all goes well and these vaccines are safe and continue to demonstrate 90 to 95 percent efficacy, we’re going to see other vaccines of a similar type,” said Moss. 2298

The E.W. Scripps Company is a partner with The Associated Press and has been following guidance from their election desk on 2020 race updates.Below is the AP's explanation as to why they have not declared a winner in Pennsylvania.The Associated Press has not declared a winner in the battleground state of Pennsylvania, because there were hundreds of thousands of votes left to be counted Thursday morning in the contest between President Donald Trump and Democrat Joe Biden.Trump, who held a 675,000-vote lead early Wednesday, prematurely declared victory in the state.By Thursday morning, his lead had slipped to about 136,000.And the race is destined to get tighter.The vast majority of the votes left to be counted there were cast by mail — and that is a form of voting that Biden has carried by a large margin.That's probably because Trump has spent months claiming without proof that voting by mail would lead to widespread voter fraud.According to the Associated Press, elections officials, under state law, are not allowed to process mail-in ballots until Election Day. 1085

The Detroit Lions will play Tampa Bay without interim coach Darrell Bevell, making him the NFL’s first head coach to miss a game because of COVID-19 protocols.Detroit’s coaching staff will also be without defensive coordinator Cory Undlin, defensive line coach Bo Davis, defensive backs coach Steve Gregory, and linebackers coach Ty McKenzie in Week 16.Wide receivers coach Robert Prince will be the team’s third head coach this season on Saturday at Ford Field against the Buccaneers.Bevell was 1-2 after Matt Patricia was fired last month. Quarterbacks coach Sean Ryan will call plays in place of Bevell, who also serves as the team’s offensive coordinator, against the Bucs. Evan Rothstein, who helps the team with research and analysis, will lead the defensive staff.Bevell said Wednesday he had not tested positive for COVID-19, but he was one of the coaches affected by contact tracing. The Lions closed their training facility on Tuesday because one player and one coach tested positive for the coronavirus, and resumed on-field preparations on Wednesday to face Tampa Bay. 1088
