The Federal Reserve is warning that an escalating trade war would pose a big threat to the economy.But for now, it's sticking with its plan to raise interest rates — whether President Donald Trump likes it or not.In minutes of its most recent meeting, released Wednesday, central bankers warned that a "major escalation" of trade disputes could speed inflation and cause businesses to pull back on investment.Such an escalation could also reduce household spending and disrupt companies' supply chains, participants noted.Some business leaders reported that recent tariff increases have already begun to cause higher prices. Others have reduced or delay investment spending because of uncertainty about future trade policy.Still, some Federal Open Market Committee members noted that most businesses concerned about trade disputes hadn't cut back their spending or hiring, but "might do so if trade tensions were not resolved soon."In the meantime, the central bank is standing by its plan for higher rates as the economy strengthens, according to the minutes.The Fed is expected to raise rates twice more this year, starting in September.The Fed meeting, held July 31 and August 1, was the first after Trump began lashing out at Fed Chairman Jerome Powell for hiking rates. The president told CNBC in July that was "not thrilled" with the Fed's actions.He used similar language on Monday in an interview with Reuters, arguing the central bank should be doing more to help the economy."I should be given some help by the Fed," said the president, who himself appointed Powell to lead the central bank.Presidents have historically avoided commenting on Fed policies. The central bank is designed to be independent from political interference.The Fed's minutes made no mention of Trump's criticism as a factor in its decision-making.Since Trump took office, the Fed has raised rates five times, including twice this year under Powell. The Fed has been carefully and gradually raising rates over the past several years to keep inflation in check and prevent the economy from overheating.After two further rate hikes in 2018, it has penciled in three more rate hikes in 2019.Fed Chairman Jerome Powell told the "Marketplace" radio show in July that he was "deeply committed" to maintaining Fed independence."We do our work in a strictly nonpolitical way, based on detailed analysis, which we put on the record transparently, and we don't take political considerations into account," Powell said in the interview.Powell is expected to speak on Friday at an annual economic symposium in Jackson Hole, Wyoming. 2611

The continuing debate about children and vaccines can get pretty heated. One of the concerns is that vaccines weaken a baby's immune system against other diseases, but new findings should ease that fear           For many little ones, routine vaccinations are a rite of passage.  And sometimes, there can be a lot of them."Some parents are concerned that kids get too many vaccines in too short of a time," says Dr. Jason Glanz with the Kaiser Permanente Colorado Institute for Health Research. "So by the age of two children receive up to 10 vaccines and 26 shots and so that is a lot of shots."That's why Dr. Glanz and his team set out to see if getting that many vaccines was harmful."Thankfully our study show that it wasn't harmful," Dr. Glanz says.Dr. Glanz says many parents are concerned vaccines could overload their child's immune system and increase their risk of getting an infection in the future.The NOW's Kumasi Aaron asked Dr. Glanz, "Is there such thing as overloading an infant with vaccines?" "We did not see a list of that," Dr. Glanz replied. "We saw no evidence that receiving all the vaccines and receiving them on time in anyway damaged the child's immune system."The study looked at infants two years after they got those vaccines, and found they weren't likely to be more susceptible to other infections not targeted by those vaccines.Dr. Glanz says, "I'm hoping he provides some reassurance that these vaccines are safe and the benefits greatly outweigh the risks and that if they have any concerns that they should talk about it with the doctors." 1658

The Federal Aviation Administration has issued a safety alert about flying with dry ice onboard, in anticipation of the huge nationwide distribution project anticipated to start in the next few days once the Pfizer COVID-19 vaccine is approved for use.The Pfizer and Moderna vaccines both need to be kept at extremely cold temperatures, requiring the use of dry ice during transit.Dry ice is frozen carbon dioxide that is pressed into blocks or pellets. It doesn’t melt into a liquid, it moves directly from a solid to a gas and that process can happen quickly at high altitudes.That can cause problems onboard a plane, such as causing the plane to weigh less at times during the flight and change its center of gravity.“CO2 sensors installed or carried in the aircraft or worn by the pilots and other crewmembers will assist the operator and crew in recognizing hazardous concentrations of CO2 and implementing effective risk controls,” the FAA’s safety alert recommends.In addition, they encourage maximum ventilation onboard while on the ground and in the air, asking crewmembers to check air conditioning units and auxiliary power units before flight.Exposure to elevated levels of CO2 can cause drowsiness or dizziness, and higher levels can impact breathing eventually leading to hypoxia and death.The FAA also recommends that “pilot training on specific conditions and procedures can improve pilot decision-making in the event of a CO2 detector alert or other system abnormalities.”Friday morning, Health and Human Services Director Alex Azar said Americans could begin getting the COVID-19 vaccine next week once the FDA and CDC give it emergency use approval. 1676

The elections board in Florida's Miami-Dade County has collected a set of mysterious ballots in the Opa-locka mail facility after Democrats raised concern about the uncounted votes.The uncounted ballots have emerged as one of many battles over the fiercely contested Florida elections that moved this weekend into a recount phase.Suzy Trutie, a spokesperson for the county's supervisor of elections, told CNN there were 266 ballots in the shipment and that the votes will not be counted. Florida law requires all ballots sent by mail to arrive at the election facility by 7 p.m. on Election Day, and these ballots did not meet that standard, Trutie said.The US Postal Service said in a statement on Friday that it was operating in "close coordination and partnerships with election officials at the local, county and state levels." But as of Sunday morning, it still did not confirm ballots had not been provided in time to local election officials. 957

The COVID-19 death toll in the U.S. surpassed 300,000 people Monday afternoon, according to a database kept by Johns Hopkins University. Earlier in the day, the country also surpassed 16 million confirmed cases of coronavirus.The U.S. continues to vastly outpace the rest of the world in terms of caseload and deaths linked to COVID-19.The U.S. recorded its 16 millionth COVID-19 case over the weekend, meaning more than 1 million people are confirmed to have contracted the virus since Tuesday. According to the COVID Tracking Project, the U.S. is currently averaging more than 211,000 new cases of the virus every day — or more than a million cases every five days. Seven million Americans have contracted COVID-19 since Oct. 30 — representing 45% of all cases that have been recorded in the country since the virus arrived in January.In recent days, the U.S. has been averaging more than 3,000 deaths linked to COVID-19 a day — a figure that represents more lives lost than in the Sept. 11, 2001 terror attacks. The U.S. reached the grim milestone of 300,000 deaths the same day it began distributing Pfizer's COVID-19 vaccine. Health officials hope that inoculating higher-risk individuals first will cause death totals to drop in the coming weeks.However, health officials warn that things will likely get much worse in the weeks to come. The U.S. is just now seeing the expected spike in cases brought on by travel from Thanksgiving, and more deaths are sure to follow.Hospitalizations are also expected to rise, even at a time when a record 110,000 people are battling the virus in a hospital. Some hospitals may struggle to treat an influx of patients when they are already at capacity. 1712
