While the race to develop a safe coronavirus vaccine is on, there's new evidence other vaccines could help people survive the virus.A husband and wife professor team from Louisiana State University and Tulane University worked together on research about the MMR vaccine. That stands for measles, mumps and rubella.Most children get the vaccine. It could explain why kids are less impacted by COVID-19.Testing on mice found these kinds of "live" vaccines boosted cells' ability to fight off sepsis.Sepsis is ultimately what's causing organ problems and inflammation in many adults who have contracted the novel coronavirus.“The idea behind it is, if these live attenuated vaccines are inducing the cells that will inhibit or dampen the sepsis, that gives the regular immune response time enough to get rid of the infection,” said Dr. Paul Fidel, a professor at LSU.The results of the "live" vaccine test on mice were undeniable.Researchers also point to what happened on the USS Roosevelt, where more than 1,200 sailors contracted the virus. A few were hospitalized and one died.All U.S. Navy recruits get MMR vaccinations.The professors are starting a grassroots campaign for adults to get the MMR booster.“If we're right, wow you would have the cells that would inhibit or dampen the sepsis if you ever got infected with COVID and if we're wrong, so OK you have a booster for MMR and that can’t hurt you at all,” said Fidel.“I think this concept with live attenuated vaccines inducing this response that controls the inflammation as opposed to targeting the actual viral infection, it’s going to serve as a stop gap measure until we get a real legitimate vaccine developed that’s been shown to be efficacious and safe,” said Dr. Mairi Noverr, a professor at Tulane’s school of medicine.The MMR vaccine theory is being tested on primates now. There's a push for human trials, especially with health care workers and people in nursing homes. 1948

What started as a simple gesture of kindness during the lunch hour resulted in more than 900 cars “paying it forward” over the course of over two and a half days at a Minnesota Dairy Queen. Customers in the drive thru continued to pay for the order of the car behind them.According to the Brainerd, Minnesota, Dairy Queen, the chain started around lunch time on December 3. By the end of the first day, 280 cars participated by the close of business.December 4 started with paid forward from the night before, and it went from there. More than 500 cars in the drive thru paid it forward on December 4. The streak continued through December 5."It makes people feel good. Our whole crew was pumped about it, let's keep it going, our fans, we had people come here just because they heard about it and wanted to be a part of it,” store assistant manager Sandra Quam told WCCO. 884

Why are stocks falling again? President Donald Trump says it's because Democrats are gearing up to use their impending control of the House of Representatives to investigate him. As always, when it comes to the markets, the real answer is complicated.The Dow fell by more than 600 points on Monday, dragged down by investors' concerns about the tech sector and the rising dollar. The Nasdaq fell 2% and the broader S&P 500 fell 1.2%.Apple (AAPL) fell 5% after supplier Lumentum cut its earnings and sales forecast because of weak demand, and JPMorgan cut its target price on Apple's stock. That weighed on other technology stocks, including Amazon (AMZN) and Tesla (TSLA) -- down 4% -- as well as Facebook, which fell 3%. Google (GOOGL), Netflix (NFLX) and Microsoft (MSFT) were all down more than 2%.The strong dollar also weighed on stocks. The US currency surged to a 16-month high because investors fear the European economy could stall if no Brexit deal is reached this week. Prospects of another rate hike from the Fed next month have also helped lift the dollar. The rising dollar is a signal of a strong economy, but it hurts sales and profits for American companies that do business overseas.Though Trump blamed Democrats for the drop, the Dow had actually bounced back since the midterms, rising last week in its best showing since March. Wall Street tends to like stagnation in Washington, so investors are actually just fine with Democrats taking the House.As for what Trump termed the "prospect of presidential harassment," there is not much evidence the stock market will bat an eye if Democratic leaders in the House begin investigations into the Trump administration. Stocks rose before, during and after President Bill Clinton's impeachment. 1800

What do you do when (not if) one of those cheap, vertical, plastic Venetian blinds breaks?One Lakewood man had the idea to upcycle his excessively long CVS receipt, and his tweet about it has gone viral with over 157,000 likes and 36,000 retweets.On Monday, @andrewnolan2 tweeted a picture of the improvised sun-blocking device, throwing some literal shade at the pharmacy known for its lengthy transactional records. 425

Whether planning necessary travel in the near term or fantasizing about vacationing in the ever-longer term, you might be curious how the coronavirus pandemic has affected airfare prices.We compared data from our points and miles valuations analysis to determine where and how airfare has changed since this time last year. We looked at the same routes, airlines and booking time frames for both 2019 and 2020, ensuring an apples-to-apples comparison.Although air travel has picked up significantly since the lows in April, the Transportation Security Administration is still reporting about 63% fewer daily screenings than this time last year. Has this drop in air travel demand led to a significant price drop?The short answer is: Yes, prices have fallen.Prices have dropped, but mostly in the short termThe average cost of a domestic round-trip ticket fell 23% in 2020, from 7 in 2019 to 4.This price drop is striking but not surprising given continued low demand. But the trend becomes stronger when breaking out the booking date data, with those made within 15 days dropping much further than bookings made six months in advance.The plot thickens.Airfare for long-term bookings has remained flat year over year. If you book a flight for six months from now, you’re likely to pay roughly the same price as you would have last year. But closer-in bookings, within 15 days, are not only far cheaper than they were in 2019 but also cheaper than long-term bookings.This turns conventional airfare-booking wisdom on its head. Usually, we would recommend booking flights as far ahead as possible to secure low fares. But booking too far in advance is now a recipe for getting fleeced.?

This usually means ramping up prices for nearly full flights at the last minute, when competition becomes stiffer.However, now that demand has dropped and airlines are actually falling over themselves to reduce flight capacity, the game has changed. Airlines are now competing with each other for last-minute bookings, which drives down prices. And they seem to be making up revenue by raising prices on longer-term bookings made by those few brave souls willing to plan in advance. In other words, it’s a buyer’s market for close-in bookings.Of course, these pricing dynamics, like everything this year, are liable to change by the week. If you’re thinking about booking a particular route, set up a price alert on Google Flights or another travel search tool and keep an eye on how the airfare winds are blowing.What do these unusual airfare trends mean for you? Keep it simple: Avoid booking months in advance, set up a price alert and try to shed the normal (and normally smart) habit of avoiding last-minute bookings.More From NerdWalletShould I Pay for My Hotel Using Cash, Points or Both?5 Travel Writers ‘Draft’ Their Favorite Airlines(How) Should I Travel for the Holidays?Sam Kemmis is a writer at NerdWallet.
