more losses to workers a swimming instructor. or 2 children. to. watch your story take part. in for migrants. you're watching news asia coming up today in investigations got old or at least a delay the world health organizations team of scientists had wanted to travel to china but beijing now says no we take a look at why that might be. plus the language of protest why many mongolians arm gracing an ancient writing script to resist the rise of china.

i'm melissa chan welcome to news asia we're glad you could join us the world health organization planned to travel to china this week in order to investigate the origins of covert 19 but now says beijing has blocked their team's arrival scientists have said an on grounding corey is essential to understand how the virus jumped species to humans the w.h.o. has criticized china but chinese officials say it's merely a bureaucratic delay. disappointed with this news given that 2 members had already begun their journeys and others were more able to travel at the last minute but i have been in contact with senior chinese officials and i have want to see again made made it clear that the mission is a priority for w. joe and the international team and i'm sure when he if these are to ensure the work of the global experts group in china is successful we need to carry out your necessary procedures and make relevant concrete plans and currently both sides are

still negotiating on this for more on what's at stake for both sides we have joyce lee out of the east asia bureau in taipei and joyce the perception has been that the joint china have had a pretty good relationship during this covert pandemic crisis what's happened yes it has been a lot of analysis thing that the actual has been the union to us china because it hopes to. give some time for china to you know more transparent data and information to the. whole but then it has not worked well with a strategy because this is not the 1st time the expert team has been denied to watch the origin plays of the outbreak of the endemic so how much can an investigation team learn travelling to china one entire year after the

earliest known outbreaks there many people are probably wondering isn't it already too late. it is probably too late to go to the wet market to collect evidence and data regarding the you know how the fire from animals to human but then this is exactly why china it's not so welcoming for the team to go to 100 because china authority is trying to reshape the narrative of how d.c. originated this by global scientific consensus that the fires 1st came from one hand and a lot of. citizen journalists has been detained or even sentenced to jail because they were. covering you know there was

a situation at the very 1st stage of the pandemic tell us a little bit more about how this is sensitive for china joyce. for the chinese communist party it has turned this pandemic into a celebration for the triumph in containing a fire despite many question that the virus originated in one and that. and. very poorly in the early stage and the fire spread across the world. john john a. citizen journalist was detained and sentenced to a 4 year giotto recency because she was doing what live stream reporting in. joyously thank you for joining us.

our identity and our sense of nationhood to an extent is connected to the language that we speak sometimes it becomes a political statement more and more that's become the case for people who identify as goalie and most of them live in the country or in china's province of inner mongolia language emerged there as a lightning rod issue last year after beijing announced mandarin would replace mongolian in course school subjects many parents there saw it as an effort by china to embrace their culture correspondent bolinger went to the city of whole hot after rare protests erupted over the new policy here's a look back at the tense atmosphere he observed there i am. learning these groups as you can see security measures. but you can be wrong to. do it with your head. in the beginning of the week the students try to organize

a strike that would turn the losses because of the new finding would be useless but police has exerted pressure on the families and now it's the most you can talk to me. as you can see here is the world lot. of few people maybe. but it was easy to learn more. about the need to be afraid of them or 3. times and i'm not alone you know. you don't want to be going to. be. looking. at it and it's going to be a little bit like. those efforts by beijing to diminish the mongolian

language within china has caused a stir across the border in mongolia proper a country of 3000000 people there the language is classic script is now seeing a revival. it used to be an artifact of history now it's a sign of protest not for what it says but because of the way it's written in vertical script most mongolians grew up using cyrillic but this engine script is making a comeback sparked by what's happening in among across the border in china. protests to save the mongolian language in minimal goli a went viral here. i believe mongolians were not aware that in a mongolian swer so dedicated to the ethnic culture and the language until people saw all their protests. the sudden

revival started earlier this year after beijing introduced a language reform in. schools had to replace mongolian with mandarin as the language of instruction for core classes. critics say the policy aims to assimilate local minorities into the dominant han culture and let you read protests in the region. it also hit a nerve in neighboring mongolia. it should be alarming to us to know that people who speak our language are losing that identity. the. fight isn't just a fight to use different language. this is a fight to remain mongolian. but that inspiration takes quite a bit of concentration students have to master archaic language and learn new

grammar rules. who don't is also in need of a digital facelift developers have also been at work designing ways to incorporate the vertical script into apps. it is simple to read and write in proficiency we need social media platforms to practice and used a model in script to be a way of communication has already shifted this group should exist in digital platforms so that's how we can save all script and identity and. still on the greens really need to learn who is a paper and pen then practice makes perfect. for more we have journalists highly and by at sub to joining us from all end but tart mongolia can you tell us more about how mongolians in mongolia react to china's new language policy. first of all thank you for the

opportunity yes we are the brain manage our reactor the protests are in our own gornja the famous song called. all young when there are protests in broke hearts of many modern mongolian who are too easy to use english or other foreign languages as i heard he. had no intention to. get off their tradition or turn up or their culture or their national identity are in among our guests yes in short the practice need that mongolian in mongolia to make more effort just. to study their own articles get. the progress made us realize that.

there is great and the language is theirs not our our our national and that invented so late so we thought that it must carry the heart so it can on generation to generation. also i'd like to mention that those protests and. protest it was not only. studied the language it also spike at this gushes the relationship between 2 mongolians the great go yeah and the ones in the goal yeah yes so give us a sense of the level of cross border exchange between mongolians and enter mongolians is there much communication between the 2 groups or not really. in order to answer that question i have to give provide you some facts for example mongolia was sealed off from the world 70 years. so the

communication can actually it was lost so we were we were only able to talk to each other or interact with each other after the afternoon got it became the mechanic and also there are some problems after teaching our teaching history the way they teach in history is pretty much. not enough so model isn't what we have missed understanding about inner mongolia and we used to think that you know i'm going are chinese or half chinese or they all become chinese people that's. that's what that's what we used to think but not now it's changes thanks to all those protests we learned that we learned that in the ongoing are just like us. they are still loyal to their nation our culture our national language and

they are ready to sacrifice their life to protect their own culture language script and by at sucked thank you so much for your time. that's it for now thanks for watching see you next time and goodbye. to. the fight against the corona virus. as the rate of infection in developing what does the latest research. information and contact the coronavirus update. on t w. come to. one problem. in north america seem.

to be a very good move if you can't get it. how will climate change affect us and our children. w dot com slash water. when t 21 began with a world wide ambition to vaccinate as many people as possible against code 19 but in many parts of the world it's been a slow start there aren't enough vaccine doses available yet and sometimes logistical problems add to the shortages. that's my view kate decided to simply delay the 2nd vaccine dose to increase capacity we should prioritize having as many people getting the 1st dose as possible. and that and that will ours to get

protection to more people more quickly. than otherwise. others think looting germany discuss this option but there are no. clinical trials available supporting this move what if it goes wrong. what indeed hello welcome to our code 900 special i want to get jones and like many of you i'm waiting for my turn to get vaccinated but i don't want to be a guinea pig so i'm not quite sure what to make of those developments and in a moment i'm going to ask about rolla just about this but 1st a look at where we're actually at swiss covert 1000 back scenes. only a handful of different vaccines have been authorized so far some countries have already kicked off fix a nation complaints. supply remains extremely limited despite manufacturers ramping up their production capacities. most of the vaccines

require an initial job and then a booster shot some time later to provide adequate protection. with a global population of 7800000000 people that means that almost 16000000000 doses need to be produced for everyone to be vaccinated producing that amount will take years some experts say but time is of the essence the longer the virus keeps spreading around the globe the higher the likelihood of mutation just recently scientists discovered 2 new variants in the u.k. and south africa that appear to be much more contagious the fear is that those mutations could render even strict lockdown measures useless and eventually even the vaccines now experts are trying to find ways to get more shots into more arms the discussion is focused on 3 options. the 1st

option is to delay the 2nd dose that would mean more people could have a 1st shot which might provide some protection the u.k. and denmark have approved the measure and are about to put it into practice but some experts warn that immunity might wane in the weeks following the initial shot that could create ideal circumstances for the virus to mutate and become resistant . the 2nd idea is to cut the doses in half which would double the number of people that could be vaccinated while there are indications that the immune response is the same experts say we can't know for sure . the 3rd option is to combine 2 vaccines so that the composition of the booster is different from the initial one the reasoning behind that idea is that both the astra zeneca and biotech vixens target the virus a spike protein but with 2 different methods. the problem is

none of the proposed alternatives has been tested so far. but trust is everything and for many getting a brand new vaccine is already a leap of faith so let's talk more now with julian tung he is honorary associate professor and clinical biologist at the university of leicester good to have you with us tell me isn't it a bit risky to change the way we use those vaccines on patients without proper clinical trials to back up those changes as to how the vaccines are administered. ok so we do have some dates on 1st if it is c. for both the vaccines. and the other some of the vaccine although the clinical trials were not designed to test 1st as if it is the only we could see some protection were there from other vaccines our experience with those vaccines is that the 1st those actually does most of the work with the 2nd that's just being abused so most people respond the 1st is the 1st as well as to use

a sufficient sufficient immunity that commute for the beast of by exposure the virus in the population right the 2nd dose is ready but but this is not how they were designed certainly by and take pfizer already mentioned that they they have been dubious about extending the period between those one and today is 2 so how big is the risk that extending the period between the 1st of the 2nd gap or reducing the vaccine dennis which is also talked about that that creates a vaccine resistant strain of the virus. here so this is a theoretical risk because you don't have complete immunity but this this back to school music can even arise the 2 doses so if you suppress replications fish and really want those the risk of that mutant arising is a lot less than the no dose of the top so if you're in an arsehole of the population 2 doses of the hope of nothing is also a risk nuisance may arise not in the hall where there's no vaccine protection at

all so the risks are relative and i don't think they'll be any worse we just won't dismiss notice to what you know of the population essentially all right well there are various kinds of vaccines so before we go on let's just take a look at at some of these different kinds because one is created with the activated or dead parts of the virus another one is called the vector vaccine and it uses another harmless life virus as a carrier to transport it genes from the dangerous virus into cells in the recipient's body the immune system then detects the offending protein and creates antibodies. and then there is or there are big scenes that use message r r n a a part of the genetic viral code and these vaccines prompt cells in the recipient to produce viral proteins themselves which in turn then provoke an immune system. so with that in the back of our mind julian tang from from the university of

leicester there is talk about combining different vaccines to make up for shortages or even booster vaccines efficacy is that safe has the been done before. and so we've got some experience with the new macbook about it seems we have perth now are 7 since rex $10.13 mixing and matching is in the doses certainly in singapore though in that without a trial if the back is taught the same antigen the protein where the delivered by m.r. nay or primary and no virus or even supply protein vaccines like the flu based vaccine design i think the minister even if it is the will be fine do you feel that people will trust this kind because this this is all going extremely fast and on the fact that we have a vaccine already within a year do you think that people will trust all those different combinations. so they will have to explain to the people and make them understand more about the

vaccines to give him the confidence that in fact what we do is just to live in the same antigen and use the same immune response we just slightly different areas and the carriers shouldn't really make that much difference to the carriers just ingest immune response to react even more against optical antigen and delivering it in a different way to the body to produce the same immune response or the same integer to predict protect against the same virus so if you explain this to people understand that we live and she's about it just just like with anything more right and do we actually know how long immunity will last once we do get vaccinated. so some of the studies do have long term follow ups and overturn his long term follow up a few 100 days after senator vaccine has follow 250 days in the face you can go trials protection against this is no boxing versatile. against water infection for at least 5 months so we do have some long term follow up for that

data and of course the longer you leave it the longer the minutes the more immunity will wane and then that's what a 2nd dose at 3 months is going to come in julian tanky honorary associate professor and clinical neurologist at the university of leicester thank you so much care. you know what most of us conned way to finally be immune to this virus speed for 100 days 150 all maybe up to 3 months there are still tons of questions about the safety and efficacy of vaccines available and he has one such question you sent to a science correspondent stan mcwilliams. do that back scenes prevent infections entirely or do they just reduce your symptoms if you catch the virus. ok to answer this we need to go over the basics of how immune response works in a healthy adult immunologists distinguish between 2 different aspects of it the

innate and the adaptive immune responses and you can think of the innate responses as kind of the body's shock troops its different components react quickly and and nonspecifically to invaders especially those the body has never encountered before new pathogens also set an adaptive response in motion as the body learns to home in on the invader churning out antibodies to flag it up so it's a highly specific killer cells and can recognise and and dispose of it the adaptive response which takes time to kick in also retains a memory of the invader that allows the body to respond quickly if it ever encounters the same pathogen again and you become immune to it however in new is kind of a loose term it just means that you are resistant to developing the symptoms of the disease again after having at once or being vaccinated for it but that doesn't

necessarily exclude the idea that if you are exposed after that you could actually carry the virus for a while or maybe even transmit it just not develop symptoms because you are adaptive immune system jumps on it pretty quickly the real holy grail of that. seen development as what's called sterilizing immunity that's one of a very rapid immune response wipes out the invaders subsequently so fast that it has practically no time to reproduce although trials in approved vaccines showed they mostly prevented vaccinated people from from getting ill those trials board set up to show whether people acquired sterilizing immunity until we collect more data on that even people who receive the vaccine should therefore go on the assumption that even if they are very unlikely to develop symptoms after an exposure they might still be contagious to others.

so it's all about collecting and analyzing data and i'm sure you still have tons of questions about the corona virus so keep your questions coming derek will be back tomorrow to send an e-mail to feed the english out to deal with you dr khan type expert in the subject line or leave a comment thanks for watching. branson
