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 coronavirus continues to play havoc on college football teams throughout the United States as 15 Division 1 FBS games have been postponed or canceled for this weekend.Of the 15 contests, six involved AP Top 25 teams, including No. 1-ranked Alabama, No. 3 Ohio State and No. 5 Texas A&M. No conference has been impacted more than the SEC, which postponed four of its seven games scheduled for Saturday.The most anticipated matchup of the weekend, top-ranked Alabama versus defending national champion LSU, was postponed on Tuesday after LSU reported multiple COVID-19 cases.Maryland, who was scheduled to take on Ohio State, reported eight COVID-19 cases among its players.For schools with multiple coronavirus cases, a key issue is contact tracing and quarantining close contacts of those positive with the virus. The CDC recommends that anyone who has been within six feet for 15 minutes of someone infected with the virus to quarantine for up to two weeks.Texas A&M athletics direct Ross Bjork said contact tracing was a significant factor in postponing its game against Tennessee this weekend.“The nature of away game travel (flights, meals, lodging, locker room, etc.) naturally leads to an increase in the number of student-athletes, coaches and staff who meet the criteria for mandatory quarantine based on contact tracing guidelines,” Bjork said in a statement. “We are asking everyone around our university community to stay vigilant and follow all of the safety protocols and best practices as we approach the end of the fall sports seasons.”Here are the games postponed or canceled this weekend:No. 1 Alabama vs LSUNo. 3 Ohio State vs MarylandNo. 5 Texas A&M vs TennesseeNo. 12 Georgia vs MissouriNo. 15 Coastal Carolina vs TroyNo. 24 Auburn vs Mississippi StateMemphis vs NavyAir Force vs WyomingUL-Monroe vs Arkansas StateGardner Webb vs CharlotteNorth Texas vs UABRice vs Louisiana TechPittsburgh vs Georgia TechCalifornia vs Arizona StateUtah vs UCLA 1988

The Food and Drug Administration approved on Wednesday a treatment for the Ebola virus. This is the first FDA-approved treatment for Zaire ebolavirus infection in adults and kids.Zaire ebolavirus is one of four Ebola virus species that can cause potentially deadly infections. It is transmitted through direct contact with blood, tissue or body fluids of an infected person or wild animal.The treatment, Inmazeb, is a mixture of three monoclonal antibodies and was created by Regeneron Pharmaceuticals. The three antibodies work together to bind to the glycoprotein on the surface of the Ebola virus and block it from entry into the body’s cells.Inmazeb was tested in the Democratic Republic of the Congo during an Ebola virus outbreak in 2018-2019 through a partnership between the local government and the National Institutes of Health.A vaccine for Ebola virus was approved by the FDA in December 2019.Regeneron is also the company behind an experimental antibody cocktail that was given to President Donald Trump following his diagnosis of COVID-19, and which he said “cured” him. Trump was also prescribed the antiviral drug remdesivir and the steroid dexamethasone at the time.Regeneron’s COVID-19 treatment is a mix of two powerful antibodies that are believed to boost the immune response to the coronavirus. Early results seem promising, according to initial tests and a press release from the company.The company has submitted an application to the FDA to get emergency approval of their COVID-19 treatment. 1525

The cost of sending a letter might be going up next year.On Friday, the United States Postal Service issued a press release stating that they had filed notice with the Postal Regulatory Commission (PRC) about its plan to increase prices.The new proposal would raise the price of first-class mail by 1.8% and 1.5% for other categories, the agency said.The additional ounce price for a single-piece letter would increase to 20 cents, the price for a metered mail 1-ounce would increase to 51 cents, and the cost of sending a postcard would increase to 36 cents.Items that will remain unchanged are the single-piece 1-ounce flat prices, which will stay , and the forever stamp will stay at 55 cents.The Postal Service Board of Directors believes the price increase will provide revenue for the agency and keep them competitive.The price increase will take effect on Jan. 24 after a review by the PRC. 907

The CDC appears to be making slight changes to who should be tested for coronavirus for a second time this week, after their changes on Monday sparked confusion and reaction from the scientific community.On Monday, the CDC updated their website to read that testing is no longer recommended for symptom-less people who were within 6 feet of an infected person for more than 15 minutes.This set off a wave of confusion about who should be tested and the reason for the change. All questions were directed to the CDC’s parent organization, the Department of Health and Human Services.In a statement distributed to media Thursday, CDC Director Robert Redfield said those who come in contact with a confirmed or probable COVID-19 patient(s) could be tested, even if they don’t show symptoms, according to TheHill.com.“Testing is meant to drive actions and achieve specific public health objectives. Everyone who needs a COVID-19 test, can get a test. Everyone who wants a test does not necessarily need a test; the key is to engage the needed public health community in the decision with the appropriate follow-up action,” Redfield said in the statement.The New York Times reports the guidelines are not changed on the Centers for Disease Control and Prevention’s website, and appears unlikely the agency will change them. 1326
