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 deaths of 22 more children from flu-related causes were reported Friday by the US Centers for Disease Control and Prevention in its weekly surveillance report.Those deaths bring the total number of children reported to have died to 84 since October, when the current flu season began. Three out of four children who died from the flu had not gotten a flu vaccine, the acting director of the CDC said in a Thursday news conference. "We continue to recommend parents get their children vaccinated even though it's late in the season," Dr. Anne Schuchat said. The season may continue for several more weeks, she added.  633

The Centers for Disease Control and Prevention have changed its definition of a “close contact,” which impacts the agency’s recommendation on who should quarantine amid the coronavirus pandemic.Previously, the CDC recommended that those who were within 6 feet for 15 minutes of someone infected with the coronavirus should quarantine for two weeks. Now, the CDC recommends that those who are in contact with someone infected for 15 minutes over a 24-hour period should quarantine.The CDC offers the following recommendations for those who have been in contact with someone recently infected with the coronavirus:Stay away from others, especially people who are at higher risk for getting very sick from COVID-19, such as older adults and people with other medical conditions, if possible.If you have been around someone with COVID-19, stay home and away from others for 14 days (self-quarantine) after your last contact with that person and monitor your health.If you have a fever, cough or other symptoms of COVID-19, stay home and away from others (except to get medical care or testing, if recommended).If you need support or assistance while in self-quarantine, your health department or community organizations may be able to provide assistance. 1258

The bull market turns 3,453 days old on Wednesday. It's the longest period of uninterrupted gains in American history.The remarkable run began on March 9, 2009, in the ashes of the Great Recession and the scariest financial crisis since the 1930s. The slow-but-steady economic recovery, coupled with unprecedented aid from the Federal Reserve, catapulted the Dow from around 6,500 to nearly 26,000 today. The S&P 500 has quadrupled from its 2009 low of 666. And market darlings like Netflix and Amazon have skyrocketed much further.The bull market narrowly survived countless panic attacks from crisis-scarred investors along the way. There was the downgrade of America's credit rating in 2011, the feared collapse of the euro, China's alarming economic slowdown and the dramatic crash in oil prices.Yet each scare failed to derail the steady rise of the economy and corporate profits that has underpinned Wall Street's record-breaking run. There were close calls, but the S&P 500 never dropped 20%, the trigger for a new bear market. 1050

"The CPD will be carefully considering the changes that it will adopt and will announce those measures shortly."The commission also said it's grateful to Chris Wallace for the "professionalism and skill" he brought to first debate, and they intend to ensure that additional tools to maintain order are in place for the remaining debates. 2905
