A task force of allergists and immunologists recommends those administering the COVID-19 vaccine ask patients some key questions beforehand. While reactions to vaccines are extremely rare, the American College of Allergy, Asthma and Immunology (ACAAI) said anyone being vaccinated should be asked if they have a history of a severe allergic reaction to an injectable medication. If the answer is yes, the individual should be referred to a board-certified allergist for evaluation before getting the COVID-19 vaccination, ACAAI said in a news release. The academy also said COVID-19 vaccines should be given in a health care facility where an allergic reaction can be treated. Patients must be monitored for at least 15 to 30 minutes after injection for any adverse reaction. COVID-19 vaccines should not be given to people with a known history of severe allergic reaction to any component of the vaccine. According to the U.S. Centers for Disease Control and Prevention, if you have a severe allergic reaction after the first shot, you should not get the second shot. Data regarding risk in individuals with a history of allergic reactions is very limited and evolving, according to ACAAI. Patients and doctors should balance the risks and benefits of vaccination. People with allergies to medications, foods, inhalants, insects and latex are probably no more likely than others to have an allergic reaction to COVID-19… read on > read on >

President-elect Joe Biden plans to release nearly all available doses of COVID-19 vaccine when he takes office, reversing the Trump administration’s strategy of holding back half the supply to ensure second doses are available. The potentially risky move is meant to boost a nationwide COVID-19 vaccination program that has gotten off to a slow start, with only about 5.9 million doses administered out of 29.4 million distributed, according to the U.S. Centers for Disease Control and Prevention. “The President-elect believes we must accelerate distribution of the vaccine while continuing to ensure the Americans who need it most get it as soon as possible,” T.J. Ducklo, a spokesperson for Biden’s transition, told CNN. Biden “will share additional details next week on how his administration will begin releasing available doses when he assumes office on January 20th,” Ducklo added. One infectious diseases expert noted that supply is not the only issue hampering the vaccine rollout. “I do think it is important to get all of those out as fast as possible so we can accelerate the process of vaccination,” said Dr. Amesh Adalja, a senior scholar at Johns Hopkins Center for Health Security, in Baltimore. “However, it’s not just an issue of doses, it’s about turning those doses into actual vaccinations, so we do still need more support at the state level to actually implement vaccination programs.… read on > read on >

As Americans await their COVID-19 shot, a new study of a different vaccine shows the power of Facebook posts in fueling “anti-vax” resistance to immunization. The study included more than 10 years of public Facebook posts on the human papillomavirus (HPV) vaccine. It found that nearly 40% of 6,500 HPV vaccine-related posts from 2006 to 2016 amplified a perceived risk. The data suggest the posts had momentum over time. “We should not assume that only the disease is perceived as a risk, but when research supports it, that medical treatments and interventions might unfortunately also be perceived as risks,” said Monique Luisi, an assistant professor at the University of Missouri School of Journalism, in Columbia. “It’s more likely that people are going to see things on social media, particularly on Facebook, that are not only negative about the HPV vaccine, but will also suggest the HPV vaccine could be harmful. It amplifies the fear that people may have about the vaccine, and we see that posts that amplify fear are more likely to trend than those that don’t,” she said in a school news release Luisi said the findings could shed light on the COVID-19 vaccine rollout and distribution. During the rollout, people will likely see a lot of negative information and that negative information will be what trends on social media, she said. “If… read on > read on >

Moderate-to-vigorous physical activity in middle age and beyond might help keep your brain healthy, a new study suggests. “Our study suggests that getting at least an hour and 15 minutes of moderate-to-vigorous-intensity physical activity a week or more during midlife may be important throughout your lifetime for promoting brain health and preserving the actual structure of your brain,” said study author Priya Palta, an epidemiologist at Columbia University Irving Medical Center in New York City. “In particular, engaging in more than 2.5 hours of physical activity per week in middle age was associated with fewer signs of brain disease,” she said. For the study, published online Jan. 6 in the journal Neurology, Palta’s team collected data on more than 1,600 people (average age: 53) who had five physical exams over 25 years and rated their weekly activity levels. Participants also had brain scans at the end of the study to measure their gray and white brain matter and areas of injury or disease in the brain. While the researchers only found a correlation, those participants who didn’t do moderate-to-vigorous intensity physical activity in midlife had 47% greater odds, on average, of developing small areas of brain damage compared to people who engaged in high levels of moderate-to-vigorous intensity physical activity. Higher activity levels were also associated with more intact white matter. White matter is tissue… read on > read on >

People who consume high levels of dietary vitamin C and E may lower their risk for Parkinson’s disease by almost a third, a new study suggests. Foods high in vitamin C include oranges, strawberries, broccoli and Brussels sprouts. Foods high in vitamin E include spinach, collard greens, pumpkin and nuts such as almonds and peanuts. How might the two nutrients ward off Parkinson’s? According to the European researchers involved in the new study, vitamins C and E are also antioxidants that could ward off the cell damage Parkinson’s causes. Specifically, antioxidants might help counteract “unstable” molecules and the oxidative stress that can lead to a loss of a brain chemical called dopamine, which is a hallmark of the condition. “The protective effect of vitamins on Parkinson’s disease risk might be limited to specific vitamins, such as vitamins E and C. Therefore, eating foods that are rich in vitamins E and C might help to prevent the development of Parkinson’s disease,” said researcher Essi Hantikainen, from the University of Milano-Bicocca in Italy. “Also, high concentrations of vitamin C are found in the central nervous system, where it has neuroprotective properties,” she explained. Hantikainen noted that this study can’t prove that vitamins E and C prevent Parkinson’s, only that high levels of these vitamins are associated with a lower risk of developing the disease. “Further research is… read on > read on >
