How Effective is the Flu Shot December 12 2019

penultimate is a word you don't get to use too often we're using it today welcome to our penultimate program of 2019 after tomorrow's show CNN ten will be off the air until Monday January 6 to 2020 it's always great to see you I'm Carl azuz we're jumping right into new developments concerning the United States and Cuba a Caribbean island country only 90 miles away from American soil but in some ways the two nations are worlds apart this week new rules take effect that limit where Americans can fly in to visit Cuba nine of the previous destinations on the island have been canceled now US airlines are only allowed to fly into the Cuban capital Havana this is expected to have a negative impact on Cuba's economy and it's one of the ways the US government is pressuring Cuba to make changes the Trump administration wants the communist nation to start holding democratic elections it wants Cuba to stop harassing opponents of the nation's government and it wants Cuba's government to stop supporting Venezuelan president Nicolas Maduro whom the US doesn't recognize as Venezuela's rightful leader American sanctions on Cuba's economy are nothing new but five years ago former US President Barack Obama and Cuban President Raul Castro formally started the process of normalizing relations between the two countries which had been rivals since the Cold War President Obama said decades of cutting off Cuba economically and politically had failed to influence its communist government to improve its record on human rights the critics said Cuba's human rights record didn't improve under the Obama policy either the Trump administration's pressure on Cuba includes the new flight limits a ban on US cruise ships from visiting Cuba and preventing ships carrying Venezuelan oil from sailing to Cuba second trivia which of these events is the oldest Ramadan Hanukkah Christmas or Kwanzaa according to Jewish tradition Hanukkah was instituted in the year 165 BC making it the oldest observance on this list Christmas hasn't come early this year but the flu season has and there ain't nothing merry about that flu viruses circulate around the world throughout the year but a flare-up in the u.s. is most common in the fall and winter hitting its worst point between December and February according to the Centers for Disease Control but it says it's been 15 years since flu season started as early as it has this time around currently the virus is classified as widespread in 16 states and is intense in 12 others what's also unusual is that influenza B a type of flu that usually hits a small number of people at the end of flu season is hitting in bigger numbers at the start of this one and children are particularly vulnerable to influenza B the CDC is urging Americans to get vaccinated even though the vaccine isn't perfect and many of those who get the shot still get the flu last flu season the flu killed at least 36 thousand people so this shot could literally save your life but it's far from perfect even on a good year influence effectiveness of the vaccine is about 60% on a bad year it's as low as 10% do we need to make a better flu vaccine you know we really absolutely do in September President Trump signed an executive order noting that the current system for making flu shots has critical shortcomings the order pledges to modernize the process the first step stop using eggs to make flu vaccine they grow the virus in the eggs like the eggs you eat for breakfast and then they killed the virus and put it in a vaccine but sometimes the virus changes inside the egg so it doesn't end up matching the flu that's out there spreading among people that's why some companies like this one have figured out ways to grow the flu virus without using right here we have the cells growing the virus the virus stays the same and when you make the vaccine it looks closer to what's in the wild so no eggs here anyway no eggs here anyway Trump's executive order is designed to encourage more of this technology and something even bigger something researchers have been working on for years a flu vaccine you would get only once in your life instead of every year Karen Craney is one of the first people in the world to get what's called the universal flu shot as part of a study at the National Institutes of Health 35 times the shot is prepped and medical history is made a universal flu shot is at least a decade away it's complicated it's not going to be easy but we're starting to see the light at the end of the tunnel so for now get your regular flu shot to protect yourself and everyone around you while we wait for something even better since we first reported on the ocean cleanup project which uses a giant u-shaped tube and a net to corral plastic in the ocean it's hit some headwinds about a year ago one of the devices broke and scientists have questioned whether it's money well spent and they've floated the idea that the project could actually have a negative effect on the environment but ocean cleanup has had some success since then and it's hoped to become one of a number of solutions to the problem of plastic in the ocean we see here actually this the stomach contents of a single sea turtle that was found dead two years ago this is what was all-in-one sea turtle in situ look at all that plastic there are approximately 150 million tons of plastic in the world's oceans and a recent UK report predicts that that number will triple in the next decade pieces of plastic in the ocean can kill sea life threaten industries like fishing or tourism and negatively affect our health when they end up in our food that plastic is still going to be there in one year it's so good to be there in ten years it's probably still going to be there and 100 only if we go out there and clean it up this amount of plastic is going to go down one young Dutch inventor and his team have their sights set on solving the plastic problem how it's an almost 2,000 foot long floating pipe with a net hanging below if you look around the world there's plastics washing up on beaches basically we design an artificial coastline here as a method of taking the plastics out of the water over there the wind is like propelling the system through the area such that the the open end of the you so to speak is going forward so it's kind of like a catcher's mitt for ocean blast yeah exactly and every couple of months there's a boat coming a bit like a garbage strike in the ocean and that takes the plastics out there on the boat and brings it back to shore this first version of the system was deployed to much fanfare in 2018 but it failed to collect and retain the plastic since then the team has added a parachute to slow it down and a cork line to prevent the plastic from going over the top of the floating pipe now the team says the new system is working but critics have worried about the system's effect on marine life are these the tubes that we see out there yeah so we have the floater at the top that's obviously keeps it afloat while we have the screen underneath it that prevents plessy from going under it so we don't have anything that can entangle marine life and what happens is that the current flows underneath it all the plastic which floats will remain in this zone and in front of the kingdom system you obviously have a ton of support for your project but there's also a lot of critics out there who are saying you know you guys are just skimming the surface of this problem and you're not dealing with microplastics 92% of the plastic isn't micro plastic but are larger objects it's not micro plastics yet right so it's kind of a ticking time bomb the sooner we get that add the better they're starting with the Great Pacific Garbage Patch a floating mass of trash more than twice the size of Texas the group plans to make consumer products out of recycled plastic from the patch this pair of sunglasses we already made this from plastic coming out of the Great Pacific Garbage Patch but the ultimate goal to clean up 90% of ocean plastic by the year 2040 back in the day people well there's no way to clean this up the best thing we could do is not make it worse but to me that's a very uninspiring message you know everyone wants the future to be better than the present that's what we hope to achieve with this camp if a deck is a bridges surface is it redundant to say deck the bridge it's not if you're on this bridge in Tennessee it's all decked out as part of Gatlinburg efforts to show it's Christmas spirit this is the longest pedestrian suspension bridge on the continent 680 feet of Great Smoky Mountain walkway that's also a tunnel of color so if you're a fan of lights you're not afraid of heights and the cold never bothered you anyway then leave the boughs of holly in the halls and join the chorus of jolly lads and lasses who are obviously heedless of the wind and weather as they take merrily measured steps across a bridge deck with falala lights that look like Yuletide treasure the Bally as the old year passes i'm christmas carol azuz and we'll see you tomorrow for our last show of 2019 [Music]
