He pleaded guilty two years later and was sentenced to two months in federal prison.The district hasn’t had a permanent superintendent since September when Julio Fonseca resigned amid allegations of financial wrongdoing.Jose Arturo Sanchez-Macias then stepped in but stepped down two months later following questions regarding payments to himself and his predecessor.Parents and teachers in the district say they want results to create a stronger learning environment they say students deserve. 749

SAN YSIDRO, Calif. (KGTV) — San Diego County will set up a coronavirus testing site at one of the world's busiest border crossings.County Supervisor Greg Cox said Wednesday the testing site will be at San Ysidro Port of Entry's PedWest crossing and serve about 200 tests daily. The testing site will be used for essential workers coming into the U.S. from Mexico and returning U.S. citizens. The walk-up site will also be appointment-free.PedWest serves pedestrians between Tijuana and San Diego. 504

Scientists, doctors and the public are eagerly waiting to hear how effective a COVID-19 vaccine will be and how soon it could be available to everyone. But when the vaccine is ready, some will be racing to be first in line, while others will be cautiously waiting to see how it plays out."Only about half of people get a flu vaccination polls are showing. In terms of the coronavirus, that’s saying that a third to maybe as much as half of the population will not want to get a vaccine," said Arthur Evans, the CEO of the American Psychological Association.Evans is concerned about whether people will be willing to get the COVID-19 vaccine when it comes out. How people are educated about the upcoming vaccine will be crucial."Right now, I think there are a lot of people who want to take a vaccine and to get a vaccine, but if people feel that this has been rushed, that they don’t feel all of the normal safety measures have been taken, it's going to be much harder for people to take that step," explained Evans.Dr. Bali Pulendran, a pathology, microbiology and immunology professor at Stanford University, says just because a COVID-19 vaccine is being expedited doesn't mean it's any less safe."It's a very established, lengthy process. It’s expedited now because of certain technologies such as the mRNA technology that really helps you accelerate this process," said Dr. Pulendran.He says the creation of a vaccine is rigorously tested, first with mice, then primates, and finally, humans. Tens of thousands of people are currently choosing to participate in COVID-19 vaccine trials."And so, this is a development and paradigm that has served vaccinology really well. It's really served it well in terms of enabling the licensure of some 20 or more vaccines," said Dr. Pulendran.Dr. Pulendran says every year, the flu vaccine varies in efficacy. For a good year, it could be 90 percent protective, while the next year, the flu shot may only be 10 percent effective. The COVID-19 vaccine is expected to be 60 percent effective."I think for me, personally, if I saw a vaccine coming out in the next year or so that had a 60 to 70 percent efficacy, that to me would be very encouraging," said Dr. Pulendran.The public, though, may still need some convincing."One of the hardest things for the general public to embrace is the idea of probability. We like to know definitively if something works or not,” said Evans. “The reality is that a vaccine is a probabilistic issue. It's highly likely that you won’t contract, whatever the condition is, but it’s not 100 percent."Evans says the key will be in how the vaccine is marketed to the American public.Dr. Pulendran hopes any positive data and outcomes of the COVID-19 vaccine trial will encourage as many people as possible to get the vaccine when it comes out. 2823

Scientists are reporting that the antibodies people make to fight the new coronavirus do not fade quickly. The new study is the most extensive work yet on the immune system’s response to the virus and is good news for efforts to develop vaccines. The report published Tuesday in the New England Journal of Medicine. It was based on tests on more than 30,000 people in Iceland. It found antibodies lasted for at least four months after diagnosis. The study also found that more severe cases of the coronavirus led to a stronger immune response to the virus."Among recovered persons, antibody levels are higher in older persons and in those more severely affected by SARS-CoV-2 infection," according to the research. Independent experts say if a vaccine can spur production of long-lasting antibodies like that, it gives hope that immunity may not be fleeting. That's what some smaller studies previously suggested.While the research was promising, it did also find that Icelanders are vulnerable to a second wave of the coronavirus even with the number of potentially immune citizens. 1092

Scientists and medical professionals across the country are working to learn about the coronavirus’s effect on children. There's still a lot they don't know about how the virus affects children.With children often not showing as many symptoms as adults, experts say kids can help us learn more about the novel coronavirus. Dr. Beth Thielen, a pediatric infectious disease physician and professor at the University of Minnesota, says people could be looking to children, especially as they go back to school, to find out more about the coronavirus."I mean, I hope so. I think this provides a very rich opportunity to understand a lot of basic things about the immune system and why diseases manifest differently in adults and children," says Dr. Thielen.Dr. Thielen says from possible protective measures of the MMR vaccine in children to t-cells, there's so much people can learn from how children's bodies combat viruses."It is thought that t-cells play a substantial role in helping to clear viral infections from the lungs. There are people looking at t-cell responses but they've lagged a bit behind with the data coming out on t-cell responses hasn’t been as prominent as the antibody studies," says Dr. Thielen. She adds, the reason people are looking at t-cells and children is because t-cells decline with age."I think they are critical. We all have them, they work to protect us from infection and potentially they are more efficacious in younger people potentially. Although, I think that really hasn’t been clearly worked out for SARS COV2," says Dr. Thielen.Dr. Jay Varkey, an epidemiologist at Emory Hospital in Atlanta, Georgia, agrees. Dr. Varkey says scientists are also looking into why children older than 10 years old, are more likely to have more serious symptoms with COVID-19."I think the reasons for that are complex. I think part of that might be related to some sort of existing t-cell immunity, and to what that is whether that’s to memory cells that are acting against a previous seasonal coronavirus that would just cause cold like symptoms, or whether its related to something more complex -- I don't think we’re there in terms of understanding," says Dr. Varkey.Dr. Varkey says, while children can help us understand COVID-19 better, it's also up to the adults to make sure they're growing up in a healthy, safe environment."We will learn much from kids but one of the messages we’ve been emphasizing in the hospital is that if we, again- and I answer this both not just as an infectious disease physician but also as a parent to two school age kids--we as adults have a responsibility to try and make our community safe to actually allow in-person learning," says Dr. Varkey."I think that we often think of children as getting a lot of these infections and the fact of the matter is most adults are getting exposed, as well, but our immune systems are sort of experienced at seeing them and we don't get sick," says Dr. Thielen.Dr. Thielen is a member of the Pediatric Infectious Disease Society and says she and other doctors in their scientific groups are advocating for more pediatric research to truly understand how certain diseases, including COVID-19, behave in children. 3217
