what's going. on now jazeera. a virus that's mutating song march vaccines could be ineffective within a year we have the details of a scientific survey to covert 19. other him to the now this is al jazeera live from doha also coming up she died after her neck was broken outrage at the treatment of a refugee while in police custody and mexico. fighting for freedom support grows for protest the use of being jailed under thailand's law against defaming its wealthy. and palestinians commemorate land day marking the loss of their

territory and israel's occupation. the world may have a year or less before the covered 19 vaccines available right now are no longer effective that is the warning from a survey of nearly 80 scientists from $28.00 countries 2 thirds say that within 9 months the virus will have mutated so much the vaccines will need to be modified nearly all say it's because of an equal access to inoculations too many countries haven't been able to vaccinate their people and that lack of coverage will allow the virus to adapt and change quickly and new variants pose a threat to all countries whether people are vaccinated or not scientists say the key to avoiding this is to share the technology they're calling for companies to lift patients so governments can increase supply quickly to stop their hits emerging professor michael baker is a professor of public health at the university of otago in new zealand he says the

warnings from the report are accurate. you could disagree with some of the exact details i mean because that seems don't suddenly stop working we have civil different vaccines and they all have different characteristics but i think the broad principle is really true and that is that we need to met some eyes for team coverage as regularly as possible and that's where multiple reasons have fiercly or prevent and this serious d.s. and long term disability it was all our societies and economies to resume normal activity record label and as i think they're pointing out here the more rapidly we get high coverage the better the chance we have of keeping the here of viral evolution or fortunately some of the of the new vaccines particularly the are in a vaccines can actually be modified very rapidly and this is again. minor changes to keep it here of the of our evolution that reformulation process so

i think we have got tools to beat the virus it may be that we have a booster every 6 months or 12 months and this is not unusual i mean we do this with influenza vaccine already we expect to have a vaccine every year partly to boost immunity and partly to keep the hit of the viral evolution but one thing i think is really important is that we don't stop our focus on public health measures because you know at the moment the elimination approach using public health measures is protecting almost a quarter of the world's population from this pandemic so i think the future success relies on using both elimination approaches public health measures combined with the record vaccine rolled out in very strategic ways and i really think that one of the goals may be progressive elimination of the virus across the planet and

even the possibility of global reddick patient i think needs to be. consider. today's health care system and funeral services are under increasing pressure as covert 19 infections surge the country recorded 7000 new cases for the 5th day in a row on monday symmetries in the city of el paraiso having to store bodies in containers chile is on the an extensive locked up to curb soaring infections despite having the highest vaccination rate in latin america. in australia the city of brisbane is going into a 3 day snap lockdown after more than a dozen new locally transmitted coronavirus infections were detected queensland state premier says the cases are of the highly infectious you caves trained under the latest restrictions people will only be allowed to leave home for essential work shopping care duties or exercise schools will also be closed we have had a lot of people now out in the community infectious so that's why we need this 3 day

getting reports of dozens of people being allowed to cross into a thai border town to seek medical treatment some of arrived for them by boat to see them print being put on stretchers being put into an ambulance and we've seen some of them with what looks like burn injuries now we know the myanmar military carried out over the weekend in korean state. protests are still taking place all across towns and cities in law we've seen pictures of people gathering in hundreds in towns in cities holding placards protest placards we're not getting reports yet of a crackdown by the myanmar military on tuesday but we do know that on monday according to activists groups on monday the non-monetary killed as many as 14 people this is according to an ngo the assistant association for political prisoners that's been keeping track of the number of fatalities a number of the number of people arrested since the coup. that 14 people died and many of them at least 8 of them were in south. south doggoned district in yangon

it 3 crisis a global approach the us rather than the me and a collective commitment at the highest particular level. the next been damage is not the question of if but when so we must be ready and we have no time to waste. this treaty unbent dimage would be routine it turns to to sion of the head sort of musician it to support the principle of has full. and to this treaty main goal is to trust a comprehensive approach to good to predict prevent and respond to pandemics to strengthen durable capacities and resilience to ensure access to medical solutions and to boast international systems that the share inch and medical

research. the importance of a one helps approach that connects the health of humans i notice and planet unfold this debate approach to work we need more to inspire and march into billy t. shirt was considered to be in the international system. 19 has been a harsh reminder no one is safe until everyone be safe and it's why lead us every week there would have come together to propose to action i think a national level immunization these are double public drouet so we need to be able to develop manufacture and diplo that seems a strictly sposi but we also need to ensure universal and treatable access to that since the scenes and tests. 19 has exposed weaknesses
