The Democratic National Convention featured a video on Tuesday highlighting the friendship between former Senate colleagues John McCain and Joe BidenThe video featured Cindy McCain, Sen. McCain’s widow.“My husband and Vice President Biden enjoyed a 30+ year friendship dating back to before their years serving together in the Senate, so I was honored to accept the invitation from the Biden campaign to participate in a video celebrating their relationship,” Cindy McCain tweeted.The Biden-McCain relationship has been well documented over the years.In 2017, following Sen. McCain’s brain cancer diagnosis, Biden appeared on ABC’s “The View,” which is co-hosted by the senator’s daughter Meghan McCain. The segment was emotional, as Biden discussed how he lost his son Beau in 2015 from the same type of cancer that ultimately killed Sen. McCain.McCain died in August 2018 from brain cancer.The Democratic Party has used the convention to paint Biden as a bipartisan candidate who can attract moderate Republicans. On Night 1 of the convention, Democrats featured former Ohio Gov. John Kasich among other Republicans to display their support for Biden.While McCain was once the standard bearer for the Republican Party, his influence in the party dwindled in his later years. In 2017, shortly after his cancer diagnosis, McCain joined just two other GOP senators in striking down legislation that would have repealed parts of the Affordable Care Act. McCain’s vote drew scorn from Republican leaders including President Donald Trump.The frosty relationship between Trump and McCain became evident following McCain’s death, when he opted in his will not to invite Trump to his funeral, but extended invitations to former Presidents Bill Clinton, George W. Bush and Barack Obama. 1786

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 Department of Justice announced Wednesday the indictment of two fighters affiliated to the Islamic State group who are alleged to have killed American journalists and aid workers.El Shafee Elsheikh and Alexanda Kotey were previously in U.S. military custody in Iraq and have been transported to Virginia to face trial.Elsheikh and Kotey, both of the United Kingdom, are two of the four ISIS fighters nicknamed "The Beatles" by intelligence officers because of their British accents. They've been linked to the killings of aid workers Peter Kassig and Kayla Mueller and journalists Steven Sotloff and James Foley.“These charges are the product of many years of hard work in pursuit of justice for our citizens slain by ISIS. Although we cannot bring them back, we can and will seek justice on behalf of their memories,” Attorney General William Barr said in a statement. “My message to other terrorists around the world is this — if you harm Americans, you will face American arms on the battlefield, and if you survive that ordeal, you will face American law in our courtrooms with the prospect of many years in an American prison. Either way, you will never live in peace — you will be pursued to the ends of the earth until justice is done.”Barr was not present at Wednesday's press conference as he is currently self-isolating amid a COVID-19 outbreak in the Trump administration. 1395

The first person known to be cured of HIV infection, Timothy Ray Brown, has died. He was 54.Brown was long known as “the Berlin patient” for where his historic treatment took place.He died Tuesday at his home in Palm Springs, California, according to his partner.The cause was a return of the cancer that originally prompted the unusual bone marrow and cell transplants Brown received in 2007 and 2008, which for years seemed to have eliminated both his leukemia and HIV, the virus that causes AIDS.His case inspired more research toward a cure, something that many scientists had thought impossible until his example proved that it was. 645

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
