The United States Consumer Product Safety Commission has issued a massive fire extinguisher recall that spans over 40 years and covers more than 120 models of fire extinguishers.According to the CPSC, it involves two styles of Kidde fire extinguishers: Plastic handle fire extinguishers and push button fire extinguishers. They may fail to discharge and the nozzle may detach.The 134 models were manufactured between Jan. 1, 1973 and Aug. 15, 2017, and includes models that have been previously recalled in March 2009 and February 2015.They were sold in red, white and silver and are either ABC- or BC-rated.According to the CPSC, there has been one death reported due to the recall. In 2014 emergency responders could not get the fire extinguishers to work during a car fire. There have also been 391 reports of failed or limited activation nozzle detachment, 16 injuries and 91 reports of property damage.They were sold at Menards, Montgomery Ward, Sears, The Home Depot, Walmart and other department, home and hardware stores across the country, and at Amazon.com.Consumers should contact Kidde to request a free replacement fire extinguisher.View the list of affected product codes below or by clicking here 1234

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 United States and China are acting tough over trade, but they're also busy talking to try to stop the situation spiraling out of control.President Donald Trump ramped up tensions last week by ordering tariffs on about billion worth of Chinese goods just weeks after announcing of sanctions on steel and aluminum imports. Beijing has responded with plans to target billion worth of US products and warnings that it's ready to inflict more pain.The moves have fueled fears that the situation could escalate into a full-blown trade war between the world's two largest economies. But Treasury Secretary Steven Mnuchin said Sunday that he's been talking to Chinese officials in an effort to prevent that."We're not afraid of a trade war, but that's not our objective," he said in an interview on Fox News."We are going to proceed with our tariffs ... we're also working on investment restrictions," Mnuchin said. "But we are simultaneously having negotiations with the Chinese to see if we can reach an agreement."The US government wants China to do a lot more to open up its vast economy to US businesses and bring down the massive trade deficit between the two countries.Trump has set a target of cutting the deficit in goods with China by 0 billion. It soared to 5 billion last year, according to US figures.Mnuchin said the United States wants China to do away with rules that require foreign companies to set up joint ventures with Chinese firms in many industries, such as automobiles, and to stop forcing American businesses to hand over valuable intellectual property in order to operate in China. Intellectual property theft is the reason the Trump administration gave for the planned billion in tariffs on Chinese goods.Mnuchin and US Trade Representative Robert Lighthizer detailed the US requests in a letter to a top Chinese economic official late last week, according to the Wall Street Journal. They included asking Beijing to reduce tariffs on American cars, increase spending on US semiconductors and provide greater access to the Chinese financial sector, the Journal reported, citing unidentified people with knowledge of the matter.A Treasury Department spokesperson declined to confirm the report."We are having very productive conversations with them," Mnuchin told Fox, adding that he was "cautiously hopeful" that the two sides could reach a deal. But in the absence of "an acceptable agreement that the president signs off on," the Trump administration will press ahead with the tariffs and other measures, he warned.China's point man for the talks is Liu He, a Harvard graduate who is one of President Xi Jinping's most trusted advisers. Liu was in Washington for talks with US officials the week that Trump announced plans for the tariffs on steel and aluminum and was recently appointed to the position of vice premier.Mnuchin and Liu spoke as recently as this weekend."Secretary Mnuchin called Liu He to congratulate him on the official announcement of his new role," the Treasury spokesperson said. "They also discussed the trade deficit between our two countries and committed to continuing the dialogue to find a mutually agreeable way to reduce it."China's official news agency Xinhua also reported the conversation, saying that Liu criticized the US allegations of Chinese intellectual property theft and warned Mnuchin that China "has the capability to safeguard its national interest."But Liu also said that China "hopes to see both sides remain sensible and work together to preserve the overall stability of China-US trade relations," according to the Xinhua report.Some experts are skeptical that Beijing will give Trump what he wants."China may be able to come up with some big ticket imports to allow it to appear to be trying to reduce the bilateral trade imbalance," Mark Williams, chief Asia economist at research firm Capital Economics, wrote in a note to clients on Friday. "But China won't be able to reduce the annual imbalance by 0bn as Mr Trump has demanded."And "the chances of China making substantive changes to its practices on intellectual property are also low," Williams said, adding that the practices are seen in Beijing as "a key element" of efforts to develop the Chinese economy.  4274

  

The US Treasury Department is sanctioning Turkey's ministers of justice and interior in response to the detention of American pastor Andrew Brunson, White House press secretary Sarah Sanders said Wednesday."We've seen no evidence that Pastor Brunson has done anything wrong," Sanders said, calling Brunson's detention "unfair and unjust."The two ministers will have any assets and properties under US jurisdiction blocked and US persons will be prohibited from engaging in financial transactions with the ministers. 523

  

The unemployment rate has dipped below 4 percent for the first time since 2000.The United States added 164,000 jobs in April, the Labor Department reported Friday. That was slightly below what economists expected. Unemployment dropped to 3.9 percent, the lowest since December 2000."The employment situation continues to surprise everyone," said Robert Frick, chief economist with Navy Federal Credit Union. "Getting down to 3.9 is quite a marker."Wages grew 2.6 percent from a year earlier. That was also slightly below expectations.The report indicates another month of solid job growth for an economy that has been expanding for almost nine years — the second-longest streak on record.Hiring gains in April were broad. Professional and business services added 54,000 jobs, health care added 24,000, and manufacturing posted an increase of 24,000 jobs.The mining sector added 8,000 jobs, extending its gains. Employment in mining has risen by 86,000 since October 2016.The wage growth number seemed unlikely to alarm Wall Street, which has been worried in recent months about inflation. Stock futures were little changed after the report came out.Inflation is closing in on the Federal Reserve's 2% target, gasoline is heading toward a gallon, and companies are reporting cost pressures. Faster inflation could force the Federal Reserve to raise interest rates more quickly than planned.Frick believes unemployment will keep falling as businesses offer more attractive wages and benefits to fill openings."There's still hundreds of thousands of more people who will enter the workforce," he said. "I think we can get down to 3.5 percent."If unemployment falls much further, it will reach territory not seen in half a century. Unemployment fell as low as 3.8 percent in April 2000, in the waning days of the technology boom. The last time it was lower than that was 1969. 1898
