Take the other hygiene measures seriously too. But we still have these feeling of insecurity specially after the summer vacations where people were able to travel again. We might not be doing enough to get at least some warning about possible Health Issues or. Yards of the compound the school is one of just 3 in germany to provide regular coronavirus test all its students and staff for free once a week they use a self testing kit at home and bring the swab back to the school to have it analyzed parents feel safer knowing their children are being tested there is a course when so many people get together especially in a classroom the likelihood of anything happening is relatively high. And its a great comfort to know that tests are being done regularly. That. Around 1300 students and staff attend the school the test program is voluntary but a majority is taking part more than 1000 people so far most students think its a good idea this bite the test being slightly uncomfortable. Is actually quite simple you have a test kit which is quite selfexplanatory after the 1st time you use it its a bit uncomfortable because you have to reach the tonsils with a swab to really take a proper sample but you dont get more than a slight gag reflex. The tests are being provided free of charge by a German Biotechnology Company there have been no positive test results in the 1st 3 weeks the hope is that any infections can be detected swiftly so the school can remain open. Listen just a place of learning but also a social place you meet friends and thats why im glad the schools are reopened the interaction that we have in the classroom is impossible and thats why im glad to be back here. The school believes the test program can also serve as a model for other schools across the country helping keep students safe in and outside of the classroom. Sonic health care germany and is also board member of germanys. Medical lab Industry Association whats the use of testing at one school when you just dont have the resources to test all of them. Well well thank you for having me 1st of all were a little bit skeptical about testing and school. For one reason because what you just mentioned its resources resources are limited at the moment and they should be used for those who need testing most but secondly also because pretty under to good Quality Matters in corona testing so thats the quality of how a specimen sample is taken from someones throat and we are quite skeptical whether 10 year old kids and ive got one of those at home myself actually have the discipline to take a deep throat or a nasal swab sample the consequence of these samples not taken properly is that were going to report false negative results and thats the worst of all scenarios where were missing someone who is positive because the sample has not been taken correctly and with kids the younger they are the higher we believe that is quite a risk a 2nd be the question must be asked what the purpose is of widespread testing in schools because we know this p. C. R. Test is only a snapshot in time it gives us an information about the moment the sample is taken every school kid can get an infection on the bus home or at home in the family when doing sports and you see already have to repeat this for all kids in the country every day of the week and thats simply not possible so we advocate for more targeted testing. Work in the business whats your take on this new goggle test or what what are the best tests. The Gold Standard as we said so for for many tests not just corona test there are different methods there are different ways how to go about it different Materials Testing from blood urine and sputum throat swabs the Gold Standard so the best possible quality at this point remains the throat slope and p. C. R. Test at the same time as things develop very fast at the moment also on the scientific and Development Side for corona testing and so we are monitoring very closely what tests for example can do and whether a loss in sensitivity could be acceptable so if this loss was not big enough this could work very well be a way to replace the throat although to be honest were not talking about a blood collection or sticking a needle into peoples arms were talking about a swap which is a comparatively good way of collecting the specimens and we dont necessarily see the necessity to replace the swabs altogether when it comes to results what about these false positives and negatives people are talking about. Well every test has a has a risk of reporting or for a false result these risks in p. C. Are testing extremely low but theyre not 0 and we have to differentiate a little bit what could go wrong also if the test is false positive we are telling someone you have an active infection and in reality the person does not perhaps in a School Setting this what has been confused between 2 different people of these kind of scenarios the consequences of that but are not overly dramatic if were honest we might send someone into quarantine and into some unpleasant days accidentally but the person itself and the Wider Society were not really have a problem from that the false negatives is what we must avoid whenever we can so telling someone you are tested negative you have no effective infection but in reality there are positive and this can happen especially with slopes from the prison of the ticket problems so when the throat is not collected it is not touched correctly when the specimen is not collected professionally and that is a real risk because you have people returning to their work places to visit family to go back to sports or travel and in reality they have it or they carry an active infection so the false negatives are the ones which are risky and we do everything we can to keep the quality as high as possible to avoid them you know get all scots over thats thank you very much and the World Health Organization has updated its guidance for mask wearing is millions of children returned to school around the world it says 6 to 11 year olds should wear masks. If school if theres a transmission thats happening in a community it could enter into the School System so what we really need to focus on is bringing transmission down in the School System we have outlined guidance on how schools can reopen safely everyone agrees how important it is that schools are operating safely and weve outlined how that can be done in terms of physical distancing and hand hygiene stations respiratory etiquette the potential use of masks by the by either the workers or the children themselves and so there are a number of considerations of how the schools can be opened but again we really need to focus on reducing transmission in the community 1st. Some of your questions are the coronavirus is our science correspondent terrible yes. How many long will it take to make the estimated 5000000000 times says of a vaccine necessary to provide herd immunity to the wild. This is another question where you would need a crystal ball to say anything definite but i can hazard a guess production is a bottleneck that any vaccine will have to pass through and depending on the Technology Platform behind it that bottleneck could be more or less tight now i dont have time to talk about all the vaccine platforms out there so i just concentrate on on 3 of the most advanced in terms of trials and how long it takes to make them messenger r. N. A. Vaccines which are basically chains of specific nuclei acid sequences they can be made quite quickly but m. R. In a molecule is are also unstable and currently need freezing which complicates distribution developers and into late stage trials with m. R. In a vaccines claimed theyll be able to produce hundreds of millions of doses by the end of the year if approved and that they can upscale rapidly after that 2 to well over a 1000000000 doses annually a 2nd platform uses engineered add new viruses to get the body to respond to corona virus proteins its committed to producing around 700000000 doses with different partners this year if its approved finally some inactivated virus candidates are also quite far along they employ Technology Already used to produce vaccines like the one we have for polio for example but it also takes time to branch up production because the virus has to be cultivated before being cut. Hild for injections so even assuming that all those that seem candidates and perhaps others are approved i havent read anyone who expects them to bring anything close to herd immunity on a planetary scale much before 2022 and thats thats really ambitious. Finally the corona virus has robbed the zoo in city of visitors and revenue leaving zookeepers to think outside of the box ok theyre growing their own fruit and vegetables to feed the animals some of the small number of visitors now allowed in a bring food to. Make for the big credit is expensive keep is giving up part of their wages it costs around 8000. 00 a day to feed the 1400. 00 beasts animals would be a nice word a lovely ones too.
