The summer of 2020 has been one marred by civil unrest in the U.S. Since the death of George Floyd at the hands of police on Memorial Day weekend, thousands of protests have taken place across the country calling for police reform and an end to systemic racism.While some of those protests have resulted in burned buildings and looted businesses, a non-profit group reports that the overwhelming majority of Black Lives Matter protests in 2020 have been peaceful.According to a report from the Armed Conflict Location and Event Data Project (ACLED), there were nearly 8,000 demonstrations linked to the Black Lives Matter movement between May 26 and Aug. 22 — 93% of which were peaceful.The ACLED, which sources information via reports from the media, reports from government and non-government agencies as well as targeted social media reports, says that Black Lives Matter protests took place in more than 2,000 locations — including in all 50 states — between late May and August. Most places that saw protests that devolved into riots also saw several other peaceful demonstrations.The organization also notes that in places where riots were widespread, like Portland, that the vandalism was limited to the span of a few square blocks.The ACLED's findings contradict the findings of pollsters, who report that as many as 42% of Americans believe most Black Lives Matter activists are "trying to incite violence or destroy property." The ACLED believes that disparity comes from "biased media framing" stemming from "disproportionate coverage of violent demonstrations."And while BLM demonstrations have been largely peaceful, the ACLED reports that local governments have disproportionately responded with force. About 1 in 10 BLM protests were met with government intervention — a 6% increase when comparing government intervention in all other demonstrations. In half of those interventions, police used tear gas, rubber bullets, pepper spray or batons while attempting to force protesters to disperse.While not the case in every violent protest, the ACLED reports that some riots were instigated by "agents provocateurs," or outside infiltrators. For example, a man with an umbrella who committed early acts of vandalism in Minneapolis has since been linked to Hells Angels.The Black Lives Matter protests have also sparked a conversation about statues dedicated to Confederate leaders or those with colonialist or slave-owning pasts. The ACLED found 38 instances in which protesters toppled such statues, though local governments across the country have peacefully removed dozens of similar monuments on their own.The ACLED aggregates data from political conflicts around the world. According to the group's webpage, the non-profit organization receives some funding from the State Department. 2810

The U.S. regulators who will decide the fate of COVID-19 vaccines are taking an unusual step: Asking outside scientists if their standards are high enough.The Food and Drug Administration may have to decide by year’s end whether to allow use of the first vaccines against the virus. Thursday, a federal advisory committee pulls back the curtain on that decision process, debating whether the guidelines FDA has set for vaccine developers are rigorous enough.“We will not cut corners, and we will only use science and data to make that determination,” FDA Commissioner Stephen Hahn pledged at a meeting of the Milken Institute Wednesday.Exactly how much data his agency needs to be sure a vaccine is safe and effective is a key question for the advisers. An even bigger one: If the FDA allows emergency use of a vaccine before final testing is finished, will that destroy chances of ever learning just how well that shot -- and maybe competitors still being studied -- really work?“We can’t lose sight of the fact that it is in our societal interest to see these trials to completion,” said Dr. Luciana Borio, a former FDA acting chief scientist who will be watching the advisers’ debate.Plus, multiple vaccines are being studied -- shots made with different technologies that each have pros and cons.“The first vaccine is not necessarily the best vaccine,” cautioned Dr. M. Miles Braun, a former FDA scientist now with Georgetown University School of Medicine. If the trials aren’t allowed to finish, it may be difficult or impossible to ever know for sure.It’s a critical moment in FDA’s 114-year history. The government has spent billions to race a vaccine through a research process that usually takes years, and FDA faces unprecedented pressure from the Trump administration, fueling public skepticism that politics could overrule science.Interest is so high, FDA is airing the meeting on YouTube. Here are some key issues the committee will discuss:HOW MUCH EVIDENCE IS NEEDED?FDA is requiring manufacturers to do studies of at least 30,000 people to prove if a vaccine protects and how safe it is. Those studies must include adequate numbers of people at highest risk from COVID-19 -- older adults, minorities and anyone with underlying health problems.FDA has made clear that any vaccine must be at least 50% effective. And while the studies are designed to run for two years, companies may get enough evidence the shots are protective -- in at least some people -- to stop the trials early and seek what’s called an “emergency use authorization” for wider vaccinations.Despite White House objections, the FDA told vaccine makers earlier this month not to seek that speedier review until they’ve tracked at least half their trial participants for two months. With other vaccines, that’s about the amount of time when major side effects crop up.That’s not long enough, said the head of the non-profit ECRI Institute, which reviews medical technology for hospitals and insurers. In comments submitted to the advisory committee, ECRI’s Dr. Marcus Schabacker said FDA should require six months of follow-up.“Doing any less would simply risk too much, and the consequences may be severe,” he wrote. “A weak vaccine that loses public trust could poison the well for epidemic control for many years.”WOULD EMERGENCY USE DERAIL FULL ANSWERS ABOUT VACCINES?Normally when a study ends because of evidence that a vaccine is working, the participants who got dummy shots are offered the real thing.But if FDA allows emergency use of a COVID-19 vaccine, that’s not the same as having full proof the shot works, Borio cautioned.And if the participants in the placebo group are immediately offered the real shot, researchers may not be able to get answers about all the high-risk groups in the study — or tell how long the vaccine’s protection lasts, a process expected to take many more months.But Pfizer Inc., which with Germany’s BioNTech is developing one of the leading candidates, told FDA that if it’s granted emergency use authorization, it “would have an ethical obligation” to alert study participants who got a placebo and allow them vaccine access. The company wants FDA to look into “other scientifically and statistically sound methods” to determine long-term safety and effectiveness.Pfizer’s stance is likely to face pushback. The Infectious Diseases Society of America states that FDA’s panelists “should insist” that vaccine developers “present a compelling case” for how they will complete their trials if FDA grants early authorization of their vaccine.Clearing a vaccine based on premature or faulty data “could cause more harm” by “further eroding public confidence in all vaccines,” the group said.It’s an unprecedented dilemma. The FDA has previously allowed emergency use of only one vaccine, a decades-old shot that in 2005 was authorized to prevent anthrax poisoning.This time around, multiple COVID-19 vaccines are in the pipeline. Pfizer competitor Johnson & Johnson cautioned that early FDA clearance of one vaccine could “jeopardize integrity” of other ongoing trials if patients decide to drop out to seek the first cleared shot instead.The company asked regulators to explain what options are available to ensure completion of all ongoing COVID-19 vaccine trials.WHAT ABOUT LONG-TERM SAFETY MONITORING?Even a study of 30,000 people cannot spot a side effect that only strikes 1 in 100,000. So the government is planning extra scrutiny of every COVID-19 vaccine to hit the market.At first there will be limited doses given to just certain high-risk people -- and those early recipients are to get text messages daily for the first week after vaccination, and then weekly out to six weeks, asking how they’re feeling.FDA also will be checking databases of electronic health records and insurance claims, looking for any red flags.“There’s a kind of tracking that has to take place here on a massive basis that hasn’t taken place before,” said Dr. Jesse Goodman of Georgetown University, a former director of the FDA’s vaccine and biologics center.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

The summer season begins in Del Mar in less than a month, bringing with it a wealth of exciting events, but also a large influx of crowds and traffic.As one of the smallest cities in San Diego County, Del Mar has just about 4,000 people. But on any given day in the summer, more than 100,000 people could come to town. Within four months, the city hosts the San Diego County Fair, the Del Mar Horse Racing season, the Kaaboo concert weekend and also some of the busiest beaches in the area."That's part of the city's story, we're used to it," says long-time Del Mar resident Bettina Experton. "The Council knows how to handle it."The Del Mar City Council will meet Monday, May 7th, to discuss their plans for the 2018 season.They'll add ,000 to the budget for Sheriff's Department overtime. That helps put extra deputies on patrol to watch for petty theft, car break-ins and other small crimes near the beach. The city also adds lifeguards on busy weekends.To help defray the costs, parking is strictly enforced throughout the summer, with another officer added to patrol the meters. People have to pay for parking seven days a week in some areas, with meters going until 10 pm on weekends."We provide services for close to 5 million people a year," says Vice Mayor Dave Druker. "Somehow we need to pay a little bit of those services through our parking enforcement. Plus our lifeguards are on duty 365 days out of the year."The Council meeting begins at 4:30 at Del Mar City Council Chambers, 2010 Jimmy Durante Blvd, Suite 100. 1555

The U.S. has now recorded more than 3 million new cases of COVID-19 in the month of November alone, according to a database kept by Johns Hopkins University.According to Johns Hopkins, the U.S. has recorded at least 3.1 million cases of COVID-19 since Nov. 1 — more than 25% of all the cases the country has seen since the pandemic began.The spike in cases has led to a concerning jump in virus-related hospitalizations across the country. According to the COVID Tracking Project, more than 83,000 people across the country are currently battling the coronavirus in a hospital — the most the country has seen since the pandemic began. The COVID Tracking Project reports that while the entire country is seeing a spike in hospitalizations, the Midwest and South have been hit particularly hard — 69% of all COVID-19 hospitalizations across the country have occurred in those two regions.The spike has led to a concerning increase in hospital resources. In some rural hospitals in the Upper Midwest, there aren't beds to spare.The COVID Tracking Project also reports that there has been a significant uptick in deaths since the start of November. Since Oct. 31, the 7-day average of daily deaths has increase from 810 to 1,470. The current rate of deaths per day hasn't been seen in the U.S. since mid-May. The concerning spike occurs as much of the country sees the weather turn colder ahead of winter months, and comes as Americans prepare to celebrate the holiday season — something health officials warn could further facilitate the spread of the virus. The CDC has recommended that Americans not travel to celebrate Thanksgiving with loved ones and recommends against hosting large gatherings this year.It also comes as several drug companies, including AstraZeneca, Moderna and Pfizer have all reported encouraging results from their COVID-19 vaccine trials. While the companies are all pre-producing millions of doses of the drugs prior to authorizaiton, health experts say they likely won't be widely available until spring 2021. 2049

The world has spent the last several months wearing masks in public, avoiding gatherings and, in general, spending less time outside the home. But a new report suggests household transmission is one of the most common ways COVID-19 is spreading; an individual is most likely to contract COVID-19 from their spouse or significant other.That conclusion is part of a new report from the University of Florida which was published in the journal JAMA Network Open on Monday. Researchers looked at the results of 54 studies across 20 countries that included nearly 78,000 subjects.They found more than one in three, roughly 38%, of COVID-19 patients passed the virus to their spouses or significant others they live with."Infection risk was highest for spouses, followed by non-spouse family members and other relatives, which were all higher than other [close] contacts," the authors wrote.In the studies, about 17% of COVID-19 patients transmitted the virus to children they live with.Anyone living in the same home as someone who has contracted the coronavirus is at a heightened risk, but researchers say spouses and significant others are more likely to pass along the virus for various reasons, including "intimacy, sleeping in the same room, or longer or more direct exposure to index cases," according to the report's authors.The researchers found no significant difference between male and female transmission rates inside the home.A recent study from the Centers for Disease Control and Prevention found that 53% of people who live with someone who has COVID-19 will contract the virus within seven days.Health experts have urged those who have COVID-19 or have symptoms to wear a mask in their home, and isolate within the home as much as possible away from others under the same roof. 1798
