time for derrick williams and of you a question about new variants and new vaccine it's.do new variants mean we'll have to create new vaccines and how long could that process take. in the news you hear over and over again that we are at a critical juncture in the pandemic and the global vaccine campaign is often portrayed as a race against new sars coby 2 variants that could potentially prove resistance to our current battery of vaccines variants that are more contagious or more deadly are frightening of course but as long as vaccines continue to protect us against them the race remains a question of logistics it's all about getting as many people immunized as fast as possible but another big looming concern that could change that is corona virus variants that might develop what are called immune escape mutations that would allow them to evade even an immune system primed by vaccines to fight off an infection fortunately this is a situation that health authorities are familiar with since for example they have to update flu vaccines regularly because influenza viruses muta

let's check in now with our science correspondent derrick williams for another question related to climate change. demand for meat is growing and that has consequences for human health and the environment how does science trying to address this problem our hunger for meat contributes in a major way to climate change and environmental degradation and the conditions in which billions of animals are kept also poses a direct health threat to humanity since experts say intensive animal agriculture provides a nearly perfect breeding ground for pathogens to evolve so what's science doing to help improve the paradigm well 2 things jump instantly to mind one is all that research behind plant based meat alternatives that look and taste like the real thing but are mostly made from the ingredients like soy or or peas or mushrooms discoveries in a range of scientific fields especially those that involve how we process taste and texture are improving the experience of eating those products which is reflected by a recent big boom in demand. the other science driven approach to the meat problem involves t

the topic of mass vaccination campaigns and mutation is his al very own derrick williams with today's real question. is there a link between mass vaccination and me taishan of the virus. like other pathogens sars kovi to mutates constantly and vaccines do have an impact on its evolution but a less direct one then for example a theoretical antiviral treatment voided because the 2 work in different ways drugs work by wiping out an active infection while vaccines work by preventing them from occurring in the 1st place wiping out an existing infection with a medicine applies a kind of spore earth selection pressure the only pathogens that survive are those like these with mutations that make them resistant to the medicine and only they go on to spawn the next generation that's why drug resistance is such a common problem nowadays because we put pathogens under massive pressure to evolve quickly in a very particular direction which is to grow resistant to a medication by deploying vaccines on a wide scale we're also having an impact on virus evolution but a more subtle one by making a lot

and over now to our science corps want to derrick williams who has an interesting question today about covert and vegetarian. budgetary and deacons get less sick if they catch covert 19th. i was surprised at 1st that how little clear data i could find on this topic but i guess i shouldn't of that i mean what constitutes a healthy diet after all has always been controversial but i can say that i found no reliable studies establishing any direct celebrex between diet and covert severity what i mean by that is that no new evidence in the course of the pandemic has for example caused the world health organization to change its dietary recommendations although the w.h.o. certainly emphasizes the central role that fresh produce plays in a healthy diet it also continues to recommend the consumption of certain animal based products as good sources of protein that said in direct links to diet have been established because while eating mostly unprocessed plant based products doesn't guarantee perfect tells a many studies have shown that it does help reduce known communicable diseases like obesit

president of the club of rome i spoke with her earlier and we go now to our science correspondent derrick williams who is this week with his own vision for a post pandemic future. b.c. if you don't have your health you don't have anything what more can we do to keep as many people as possible as healthy as possible. this week is about visions for a post covert world so i want to talk for a 2nd about a fundamental change in perception that i personally view as as a loan overdue now a minimum standard of health for all is in shrine and in several international agreements including the 948 universal declaration of human rights but over 70 years later this pandemic has once again focused a glaring spotlight on health very very far away we still are from actually providing equitable medical care to everyone at the same time it's highlighted that none of us are safe until all of us are protected even those who can't afford it it's in everyone's best interest to provide comprehensive movies care and vaccines to everyone but the 1st question everyone asks is always who's going to pay for it and for me tha

and for the last time this week here's our science correspondent derrick williams with another of your question about back say. i was back in a to few days ago my own didn't touch and i didn't have any side effects is that normal. i talked a lot here about vaccine side effects so it's great to hear from someone who had none because that's actually really common i haven't been vaccinated yet but among friends and family who have i'd say roughly half told me they didn't notice a thing afterwards although the statistics will vary from from vaccine to vaccine it looks like for most of them at least a 3rd of all recipients don't report even the mildest of side effects like like injection site pain or or a little bit of swelling there's no way to predict in advance exactly how you'll react but but experts say 2 factors clearly increase the likelihood that you'll feel some kind of discomfort after getting the shot the 1st is your sex recent c.d.c. gave his shows that around 4 out of 5 reports of vaccine side effects have come from women with which doesn't come as a surprise really since that'

whatever the risks of vaccines they had to stay for now more on that from derrick williams. will we only have to be vaccinated once or will we need regular booster shots. once again the straightforward answer is we don't know yet but a lot of experts do think it's very likely that even fully vaccinated people will need booster shots in the future there are a couple of different reasons why that might become necessary the 1st involves the fact that the vaccines we're using now have been approved for emergency use because they were safe and the vast majority of people have gotten them and also extremely effective at least in the short term but we still don't know how long that effectiveness on average will last don't forget it's been under a year since the very 1st subjects in trials receive their 1st shots but based on what we know about naturally acquired immunity to the disease and what we know about other coronaviruses the general expectation among immunologists appears to be that most vaccinated people will remain largely immune to covert 19 for at least 6 months and like

be any und wanted side effects it's time for your questions now yes our science correspondent derrick williams. could a vaccine cause a positive p.c. on result. just a quick reminder 1st that p.c.r. stands for polymerase chain reaction and tests that employ the technology are considered the gold standard for for detecting the viral genome in swab samples now because some vaccines use information from that genome could they also trigger a positive result this question comes up all the time and the answer is is no believe me if it did then you would have heard about it because millions of vaccinated people would have suddenly started testing positive for coated 19 after getting shots that would there would be no way to distinguish between them and asymptomatic carriers it would be chaos but nothing even remotely like that has happened no if you get back a positive p.c.r. result it's almost certainly because you've been infected even though you might have coincidentally received the vaccine a day or 2 before hand don't forget that it takes your body around to we to build up a significant immune r

derrick johnson about major league baseball's decision to move the all star game from atlanta to denver in protest of georgia's new restrictive law. >>> also ahead, congressional leaders announce fallen u.s. capitol police officer williamns will lie in honor in the capitol rotunda next week. this... is a big deal. now, at healthcare.gov, millions more people can afford health coverage. due to the covid relief law, you can pay less with financial help. in fact, 4 out of 5 customers can get a plan for under $10 a month. from doctor visits to preventive services to prescription drugs- these are quality plans. you can do this. you can have coverage as soon as may 1st if you sign up now at healthcare.gov a lot of people think dealing with copd is may 1st if you sign up now a walk in the park. if i have something to help me breathe better, everything will be fun and nice. but i still have bad days flare-ups (coughs), which can permanently damage my lungs. my lungs need protection against flare-ups. so it's time to get real. because in the real world our lungs deserves the real protection of breztri. breztri gives you better breathing symptom improvement, and flare-up protection. it's the first and only copd medicine proven t

third man, william roddy bryant, are all charged with one count of interference with civil rights and attempted kidnapping today for the first time we're hearing from one of the jurors in the derrick show vin murder trial who actually voted in the deliberations, he talked to the fox affiliate in minneapolis. and they asked him if the jurors felt any pressure in any way i personally know and i don't think i don't think any of the other jurors did either. just because from being in the courtroom during the trial every day and having to witness on instant replay, somebody dying every day. the stress of that alone. you don't even have time to think about pressure. that's that's enough pressure long just to make the right decision because you're deciding someone else's life. mitchell also said quote i think we came with the right verdict. i think everybody was at peace with it. everybody was on the same page from sleeping in her car to her own apartment tonight at 5 30, the new partnership that's helping this navy veteran get back on her feet. also ahead tonight, he took a walk on his break during a work shift and then was and was then shot in the back with a bow and arrow. it was pret
