now the smell of day is over the power a lot of the stories that we cover all highly complex so it's very important that we make them as understandable as we can to as many people as possible no matter how much they know about a given crisis or issue as al-jazeera correspondents that's what we strive to do. a virus that's mutating so much that vaccines could be ineffective within a year we have the details of a scientific survey to cover 90. there in denver now this is al jazeera live from dakar also coming up she died after her neck was broken outrage at the treatment of a refugee who was a police custody in mexico. determined to see justice for george floyd the trial

over a police killing that reignited the black lives matter movement. fighting for freedom supporters of protest leaders who've been jailed under thailand's law against defaming welty. the world may have a year or less before the covert 19 vaccines that we have right now are no longer effective that is the warning from a survey of nearly 80 scientists from $28.00 countries 2 thirds of them say that within 9 months the virus will have mutated saw how much the vaccines need to be modified nearly all of them say it's because of an equal access to inoculations too many countries haven't been able to vaccinate their people 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 calling for companies to lift

patients so governments can increase supply quickly enough to stop variance from. well professor michael baker is a professor of public health at the university of otago in new zealand he joins us by skype from wellington thank you for your time so is this alarmist well cura from new zealand no i think that assessment is quite valid i mean you could disagree with some of the exact details of i mean of course vaccines don't suddenly stop working we have several different vaccines and they all have different characteristics but i think the broad prince course will be truly nervous that we need to met some eyes 15 coverage as regularly as possible and that's for multiple reasons fiercly or prevent this series d.s. and long term disability it was allowed societies and economies to resume normal activity rapidly and as i think they pointed out here the more rapidly we get high

coverage the better the chance we have of keeping of viral evolution so as it stands what does this mean for us right now if we continue the way we are going does this mean we're going to have to get new that the nation's new jabs every 3 months every 6 months i mean how quickly can the world develop new vaccines to meet these new mutations. well fortunately some of the new vaccines particularly the r. and even scenes 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 tall to beat the virus 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 as protecting almost a quarter of the world's population from the spending 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 actually be progressive elimination of the virus across the planet and even the possibility of global red occasion i think needs to be considered ok if we're looking for global errata cation coming back to my to my previous question should we prepare ourselves mentally for taking a new vaccine every 3 or every 6 months well i think already we've got the usually a to cause that seems not all of them so 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 or really we expect to have a vaccine every partly to boost immunity and partly to keep it here of the viral

evolution so this may be a scenario that works very well with 1000 is well ok have we missed the window do you think to enable equal access globally to vaccines. i don't think so but it does require a very concerted action now i mean we have obviously the civil different classes a very effective and safe vaccine so it's a huge cheve meant no the next step of course is increasing production and delivering the vaccine to those who have greatest potential to benefit but the other thing i think is really important is thinking about how we can use our limited bechstein stocks and very strategic ways to start a limited 18 transmission of this virus across the planet and i think it does require a different approach all right thank you very much for your time there professor michael daycare from the university of otago in new zealand chile's health care system and funeral services are under huge pressure discovered 19 infections search
