EL CAJON, Calif. (KGTV) - At age 73, Brian Duncan is following his own advice: if you think you can do it, you probably can.When Duncan got out of the Navy in 1967 he wanted to become a police officer. At the time, however, he says departments wanted big, tall men with 20/20 vision. He didn't fit the mold and moved on to a career in the court system.Twelve years ago, the itch came back, and Duncan joined the El Cajon Police Department's Retired Senior Volunteer Patrol, also known as the RSVP program.Now he's taking his service even further, working to become a reserve police officer.If he lands a job, Duncan will be a sworn police officer able to make arrests and carry firearms. The only difference is he'll always have to work alongside a regular police officer.Duncan says his age is not a barrier and he's doing this to make a difference in the community."I've proven I can get through the academy, so I can do it. If I didn't think I could do it or would jeopardize someone's safety, I wouldn't do it," said Duncan.Reserve officers work voluntarily and are not paid.On Friday Duncan graduates from Grossmont College's 32nd Police Academy and already has an application out for a job.  1210

Dr. Anthony Fauci warned Sunday that even if a COVID-19 vaccine becomes available, it still may not yield herd immunity.In an interview with the Aspen Institute on Sunday, Fauci — the U.S.'s top infectious disease expert — said he would settle for a vaccine that is between 70 and 75% effective."I doubt seriously that any vaccine will ever be a hundred percent protective. The best we've ever done is measles, which is 97 to 98% effective. That would be wonderful if we get there. I don't think we will," Fauci said. "I would settle for 70, 75% effective vaccine because that would bring you to that level of would-be herd immunity level."But a CNN poll says one-third of Americans do not plan to get a vaccine if it becomes available. Fauci said Sunday that if those figures hold true and a potential COVID-19 vaccine is only 75% effective, the U.S. population would not reach the herd immunity threshold that would kill the virus."That's one of the reasons why we have to make sure we engage the community as we're doing now to get community people, to help us for people to understand that we are doing everything we can to show that it's safe and that it's effective," Fauci said. "And it's for the good of them as individuals and in society to take the vaccine."Three coronavirus vaccines are expected to be studied in large-scale clinical trials in the next three months.Herd immunity comes when a sufficient portion of a population is immune to an infectious disease. That can come either come through prior illness or vaccination, making the disease unlikely to spread further. 1594

Driving through Denver, a giant milk jug demands your attention and the treats inside aren’t so bad either. Unfortunately, not all has been easygoing since the iconic shop has re-opened.Area Manager of Little Man Ice Cream, Dominic DiCarlantonio, says this ice cream hot spot hasn’t been spared from the controversy to wear or not to wear a mask in public."Ninety-nine percent of our community is amazing and has been helpful and supportive of all we’ve tried to do with COVID. The one percent has been very vocal and direct about things," says DiCarlantonio.Vocal is just half of it.Little Man Ice Cream owner, Paul Tamburello, posted to Facebook saying in one instance a customer spat on an employee. He said in another incident, a customer coughed on the counter and in the direction of workers and guests — all because they didn’t want to wear a mask, which is a mandatory requirement for the City and County of Denver.The order, which went into effect on May 6, requires residents and employees to wear face coverings while inside of, or waiting in line to enter, certain businesses, facilities or locations, such as retail stores, bus stops or health care facilities.Anyone violating the order could face a civil penalty of up to 9, per violation.The owner of the ice cream shop says those who choose not to wear a mask can pick up a pint elsewhere.This story originally reported by Ivan Rodriguez at thedenverchannel.com. 1439

Dr. Anthony Fauci again broke with President Donald Trump on several key aspects to the administration's response to the coronavirus pandemic during a conversation at Georgetown University on Tuesday.Notably, Fauci said that while schools' goal should be to reopen in the fall, the decision should be left up to local districts in areas where the virus is surging."We should try as best as possible to keep kids in school," Fauci said. "...however, that's going to vary depending on where you are in the country."Fauci said in areas where the virus isn't prevalent; schools should feel comfortable reopening to students. But in areas where cases are spiking — Fauci identified Arizona, California, Florida and Texas as states where the pandemic is the worst — the decision should be left to local officials.He added that districts should "make a decision based on the judgment that the safety of the children and safety of the teachers is paramount."President Donald Trump has called for all schools to reopen in the fall, and threaten to withhold federal funding in districts that choose not to open to students.In addition, Fauci also broke with Trump on testing. While Trump has said as recently as Saturday that spiking case numbers in America are the result of a high volume of tests, Fauci pointed out that other troubling specifics are on the rise."There's no doubt it's both (the number of tests and the uncontrollable spread of the virus that are causing case numbers to rise)," Fauci said.He added that the percentage of positive tests to the total number of tests taken is on the rise in many parts of the country. He also pointed out the hospitalizations are also up throughout the country and added that deaths may rise in the coming days.However, Fauci added that he does not believe the average amount of deaths will rise to the level of where they were in the spring, adding that the average age of a COVID-19 patient is skewing younger than it was earlier in the pandemic.Finally, Fauci was asked who Americans should trust during the pandemic."Trust respected medical authorities...who have a track record of telling the truth," Fauci said. He included himself among the group of "respected medical authorities."The discussion was hosted both by Georgetown's Institute of Politics and Public Service and the Global Health Initiative.Fauci's comments come as the White House continues to sideline him from official briefings with the Coronavirus Task Force, of which he is a member. It also comes days after reports emerged that White House officials were "concerned" about Fauci's recommendations during the pandemic, including advice from earlier this year in which he urged Americans not to wear masks.Initially, Fauci did recommend that Americans avoid wearing masks in an effort to keep from emptying an already-depleted stockpile of personal protective equipment. He has since made an about-face and has urged all Americans to wear masks. He's also admitted that the mixed messaging has been detrimental in slowing the spread of the virus."We have to admit it, that that mixed message in the beginning, even though it was well-meant to allow masks to be available for health workers, that was detrimental in getting the message across," Fauci told NPR earlier this month. "No doubt about it."Meanwhile, other White House officials — like Surgeon General Jerome Adams — also initially recommended against the use of masks. President Donald Trump has also spread disinformation about the virus, and retweeted claims that "everyone is lying" about the disease — including the CDC.On Monday, Trump claimed that despite Fauci's lack of public appearances, the two still have a "good" relationship. 3723

Each winter, many people wonder whether its worth getting a flu shot while health officials repeatedly warn against not getting one.Now a new study sheds light on the benefit of doing so. Even when the flu shot is just 20% effective it can still reduce US doctor visits due to illness by an estimated 20 million in a single year, the new report published in the scientific journal PNAS (Proceedings of the National Academy of Sciences of the United States) finds.In addition, vaccination also can prevent thousands of hospitalizations and deaths, the study authors estimated based on the average vaccination coverage rate in the United States."Getting vaccinated against influenza is beneficial to the individual and to the community even when the vaccine is of relatively low efficacy," said Burton H. Singer, co-author of the study and an adjunct professor for the Emerging Pathogens Institute at University of Florida in Gainesville.Caused by viruses, flu is a contagious respiratory illness with mild to severe symptoms that can sometimes lead to death. The flu virus evolves rapidly and new viruses circulate in different parts of the world, so each year scientists must reformulate the vaccine. Add to that an imperfect manufacturing process and even a 'good match' formulation may not be as effective as scientists would like.In fact, the Centers for Disease Control and Prevention estimated just 36% effectiveness for the 2017-18 seasonal vaccine as of February 3. (The season ends in May.)For the new study, Singer and his colleagues created a mathematical model of flu transmission and vaccination to evaluate how much illness is prevented by even a very low effectiveness flu vaccine. The research team found that at the average rate of US coverage even a poor vaccine would prevent a significant amount of illnesses, hospitalizations and deaths.For example, at just 43% coverage (the average rate of Americans who received a flu shot for the years 2012 through 2017), a vaccine with just 20% effectiveness could avert more than 20 million infections or illnesses as compared to not getting the vaccine. In addition, 129,000 hospitalizations and 61,000 deaths could be prevented.Based on the model, if more people got a flu shot, say half of the US population, the same 20% effective flu shot would prevent an additional 3.63 million infections, 21,987 hospitalizations and 8,479 deaths."When a vaccine is fully effective on 50% or more of the people who are vaccinated, you need to primarily focus on vaccinating young children," said Singer. The reason? Children are still building immunity and they pass germs around at school."As efficacy of the vaccine decreases, it becomes increasingly important for the elderly to be vaccinated in addition to young children," said Singer, since the elderly are more likely to develop complications from the flu, such as pneumonia, which can be deadly.The CDC reported a total of 160 flu-related deaths in children and 30,064 flu-related hospitalizations overall?between October 1, 2017 and April 21, 2018. The highest rate of hospitalization occurred among adults 65 years old and older.Richard Webby, a flu scientist who is part of the World Health Organization's advisory board and a member of St. Jude Children's Research Hospital's Department of Infectious Diseases, said "effectiveness estimates go up and down based on a number of factors including match of vaccine and circulating strain and probably other factors we don't fully understand.""The take home message from the past few seasons is that there is much room for improvement," said Webby, who was not involved in the research.Still, more people, particularly the elderly, need to get vaccinated even when the vaccine effectiveness is lower than hoped, Webby said: "This study suggests that even with a less than optimal vaccine there is still much public health benefit that can be achieved if these are used properly and widely." 3992
