One COVID-19 vaccine in development may be ready for review in December.Executives at Novavax say they are enrolling volunteers for a second phase of clinical trials now. The data should be ready for review within a few months.Phase 1 data showed the two-dose vaccine in healthy adults produced antibodies in all participants. Tenderness and pain were the most frequent local symptoms.When the first COVID-19 vaccines are approved, we won't know a whole lot about their safety.“We’re going to learn as we go along. There are numerous case studies in our experience where, as vaccines were rolled out, we were quite confident with the safety profile, but that evolves,” said Dr. Jon Andrus, adjunct professor at George Washington University’s Milken Institute School of Public Health.“I think that these vaccines will be safe in the sense that they won’t cause a serious or permanent adverse event when tested in 10,000, 15,000, 20,000people,” said Dr. Paul A. Offit with the Children’s Hospital of Philadelphia. “Hopefully, that will also be true in post approval when it’s tested and seen in 20 million, 30 million people.”Based on other vaccine history, a COVID-19 vaccine will likely produce some sort of adverse reaction. It could be minor typical injection site issues or something more serious.Back in the 1950s, the very first massive polio vaccination program was stopped because it paralyzed some children and killed a handful.In the 70s, the swine flu vaccine caused a very small amount of rare neurological cases. There are other issues like an allergic reaction or seizure.Still though, experts say vaccines are one of the greatest advances in modern medicine in preventing unnecessary deaths.“There is no better cost-effective intervention that medical science has to offer with the exception of safe water and sanitation, so when you look at our life expectancy, vaccines have been incredibly important,” said Andrus.The Vaccine Injury Litigation Clinic handles cases of vaccine-related injuries and deaths. They have on average just over 600 people per year receive payouts from the National Vaccine Injury Compensation Program. But they admit vaccine injuries are still rare compared to the overall numbers of administered vaccines every year.The Centers for Disease Control and Prevention (CDC) says for every 1 million doses of vaccines that were distributed, one person was compensated. 2413

Not many people like being caught speeding and getting ticketed, but one person's solution to not getting caught might lead to even more trouble. The Metropolitan D.C. Police released video earlier this week of a suspect getting out of a car and smashing a camera designed to catch and ticket speeders. The video shows the suspect knocking over the machine, kicking it a few times and throwing the camera into a ditch before getting back into a car and speeding off. WJLA-TV reported that this incident caught on video was one of six incidents that took place in DC last week. As of Tuesday, no arrests have been made in connection to these incidents.  685

OCEANSIDE, Calif. (KGTV) - The City of Oceanside has unveiled its latest effort to achieve their zero waste goals set back in 2011.Green Oceanside Kitchen is a state-of-the-art food recovery and preservation facility dedicated to eliminating waste and feeding the community."We need to do better, we need to feed our community and educate our community," said Colleen Foster, the City's Environmental Officer. The City teamed up with O'Side Kitchen Collaborative for the new project. They'll collect unwanted food from farmers, backyards, and food businesses, turning the goods into something delicious. "I could've done anything, but for me, making an impact in my community as well as it tasting good is the best!" said Vallie Gilley, Executive Director of O' side Kitchen Collaborative. The facility includes a 1,700 square foot commercial kitchen and a 500 square foot fridge that can hold about a semi-truck load of food. There's also an interactive demonstration kitchen for culinary arts training and education. Foster says more than 40 percent of what is grown and produced in the U.S. is wasted. With the new green facility, planners hope to save 20 percent of what would've gone to waste."That's thousands, if not hundreds of thousands, of pounds of food," said Foster. The facility was designed to maximize food recovery and preservation with specialty equipment installed throughout.Gillie's team will also be catering events to help support the program. 1475

On Tuesday, Arlington National Cemetery announced that the annual Wreaths Across America event scheduled for next month would be canceled due to coronavirus concerns. But later in the day, President Donald Trump said he is forcing the event to go on, despite concerns about the coronavirus.Earlier in the day, organizers said they could “no longer envision a way to safely accommodate the large number of visitors” at the event.“We did not make this decision lightly. Despite the controls developed to disperse potential crowds in time and space, and required personal safety protocols, we determined that hosting any event of this scale risked compromising our ability to accomplish our core mission of laying veterans and their eligible family members to rest,” stated Karen Durham-Aguilera, Executive Director, Office of Army National Cemeteries and Arlington National Cemetery. “We reviewed various options to safely execute this long standing event and held numerous consultations with WAA leadership and local government and public health officials.”Trump, however, called the decision, “ridiculous” in a tweet.“I have reversed the ridiculous decision to cancel the Wreaths Across America at Arlington National Cemetery. It will now go on!” Trump said.In an updated statement, the cemetery confirmed that it would hold the event.The event is slated for December 19. 1379
