A recent study by the U.S. Centers for Disease Control and Prevention found that 6% of more than 3,000 health care workers who were tested had antibodies to coronavirus. Still, after being retested 60 days later, 28% of them had antibody levels so low they were no longer detected."These results suggest that serology testing at a single time point is likely to underestimate the number of persons with previous SARS-CoV-2 infection, and a negative serologic test result might not reliably exclude prior infection," the authors of the study said.According to the CDC, blood samples were taken from 3,248 frontline health care personnel at 13 hospitals between April 3- June 19, 2020.194 of those healthcare workers had detectable antibodies to COVID, the agency said.Participants with higher initial antibody responses were more likely to have antibodies detected at the follow-up test than were those who had a lower initial antibody response, the study concluded.The authors added that the study shows that the window is limited for collecting potentially useful "convalescent plasma" from the blood of patients who have fought off COVID-19. 1151

A student's biggest dream is to walk across the stage during their school's commencement ceremony; getting rushed off the stage is not.This was the case for a number of African-American students at the University of Florida's ceremony on Saturday.As students were called up to receive their diplomas, some decided to perform a quick celebratory dance. But a faculty member didn't find the performances to his liking, and forcibly rushed the graduates off the stage. 473

A town in Virginia recently enacted legislation to prohibit anyone 13 or older from participating in the annual custom of trick or treat, which is punishable by a fine or even jail time. While front porches across America will be filled with little ghosts and goblins next week, should teenagers stay home on Halloween? You be the judge.Take our poll: 364

A US advisory panel has released their recommendations on how a future COVID-19 vaccine should be distributed, and is now seeking public comments on their draft plan.The National Academies of Science, Engineering and Medicine published their discussion draft Tuesday afternoon on their website. It is meant to “assist policymakers in planning for equitable allocation of a vaccine against COVID-19.”The draft plan has a four-phased approach to handle the intense demand for and limited supply of the vaccine when it is first developed.“While major efforts are being made to have a significant supply of COVID-19 vaccine as soon as possible, the committee has been tasked with considering the tough choices that will need to be made for allocating the tightly constrained initial supplies,” said committee co-chair Helene Gayle, president and CEO of the Chicago Community TrustThe plan states in the first phase “would be ‘frontline’ health workers—health professionals who are involved in direct patient care, as well as those in transport, environmental services staff, or other health care facility services, who risk exposure to bodily fluids or aerosols. Under conditions of such scarcity, access should not be defined by professional title, but rather by the individual’s actual risk of exposure to COVID-19.”Their plan also gives higher priority to older Americans living in group settings. They cite data showing about 80 percent of all COVID-19 deaths in the US occurred in people over the age of 65, and a significant proportion of them were people living in long-term care facilities.“Recognizing the importance of education and child development,” tier 2 includes teachers and school staff, as well as those with pre-existing conditions that put them at a heightened risk of severe complications from COVID-19 and those living in group housing situations not included in tier 1.The group states that by the time there is enough of the vaccine to reach tier 4, “ideally, these individuals would be willing to participate in an egalitarian process (such as a lottery) if there are persistent local or regional shortages in this phase.”The group that developed this draft was formed in July at the request of the National Institutes of Health and the Centers for Disease Control and Prevention.“We are pleased to help inform the government’s decision-making process and provide our expert advice for priority-setting for the equitable allocation of potential COVID-19 vaccines,” said National Academy of Medicine President Victor J. Dzau. “Input from the public on this draft framework, especially from communities disproportionately affected by COVID-19, is essential to produce a final report that is objective, balanced, and inclusive.”The public comment period will be open until 11:59 p.m. on Friday, September 4. Commenters will be able to download and review the draft before submitting a comment at nationalacademies.org/VaccineAllocationComment.A final recommendation will be published this fall to include any changes following public comment. 3069

A trip to the grocery store can be a difficult and stressful outing for a senior. So, two high schoolers from Maryland jumped in to help their own neighbors, and now their idea is spreading across the nation.The students, just 15 and 16 years old, are coordinating hundreds of free grocery deliveries for seniors in need during the pandemic.“We’ve learned there’s a huge problem, unfortunately, when it comes to senior hunger,” said Matthew Casertano.Casertano and his friend, Dhruv Pai, started by making grocery deliveries to their own grandparents.“I saw the fear in their eyes every time they went to the grocery store,” said Pai. “There was a trade-off they had to make between the necessities and their personal safety that I wanted to avoid at all costs.”“We knew we couldn’t rely on the goodwill of people wearing masks, keeping social distancing, so we had to do the shopping,” said Casertano.Then, one afternoon on the carpool ride home, the teens had an idea. “We thought, ‘What about people who don’t have grandchildren who can’t do the shopping for them?’” said Casertano.That’s when they started Teens Helping Seniors, where any senior in need can email a grocery list for teens to pick up at the store.“We will coordinate a volunteer in their area who can service that request in a one to two-day turnaround,” said Pai.The teens do all the shopping, and then drop off and sanitize each order. It’s a simple favor that means so much to those they help.“I thank you, and I thank God for you, for making such a unique individual as every human being is, but you’re showing it, you’re showing your heart,” said Marie Cavill, a senior who fractured her back during the pandemic. Cavill has physically been unable to leave her home, but she is also frightened to go out and risk a possible COVID-19 exposure.The teens said they were shocked by how many volunteers this program now has. They have 26 chapters in the United States and one chapter in Canada, with more than 600 volunteers. Because of its immense success, the group is now helping with more than just groceries.“Now, we cover things like mental health support for seniors suffering from the after-effects of isolation,” said Pai.It’s simple things like calling to say hello or leaving an unexpected box of cookies with an order that’s bringing generations together.“Despite this huge gap in who we are and what we have in common, we’re still able to help each other through this pandemic, and that’s something my own grandmother taught me at a very young age—is to always help strangers,” said Pai.“They are showing what our young adults and teenagers have the capacity to do,” said Cavill.If you’d like to send in a grocery list or learn how to volunteer, visit TeensHelpingSeniors.org. 2767
