the vaccines that have been funded and accelerated are all novel technologies im not saying that they are not going to work but they are novel bottazzi cautioned those tactics present a risk fauci acknowledged because its unclear which vaccines now being tested will end up working or working the best but its a risk developers must take more her group at texas childrens hospital and other vaccine producers are staying with triedandtrue development methods including the incorporation of a complimentary ingredient called an adjuvant which boosts the immune systems response to the vaccine thats the hard message not all vaccines including several covid19 frontrunners use adjuvants but many researchers consider it safer my concern is that people are hearing we are going to see things in a year or 18 months bottazzi told abc news typically pharmaceutical companies would wait to see if their vaccine works in clinical trials before ramping up production a patient receives a shot in the firststage study of a potential vaccine for covid19 the disease caused by the new coronavirus at the kaiser permanente washingto show more ted s warrenap theres a long road after safety you still have to do a lot of things before you can confirm the efficacy and give this to the public en masse bottazzi added that way they can be ready to distribute widely when its finally proven safe and effective with more people being infected and lockdown orders creating immense financial burdens with so many not allowed to work the question becomes even more pressing is there a viable vaccine in sight because once you know it works you cant say great it works now give me another six months to produce it the long road to vaccine development vaccines train a persons immune system to recognize a pathogen and attack it before it infects healthy cells echoing that newer vaccine technologies may be more expensive timeintensive and difficult to mass produce levy said his group at harvard instead is focusing on finding an adjuvant thats particularly effective in vulnerable populations this method could be used to treat those hospitalized with the novel coronavirus as well as boost the immune systems of healthy people at the greatest risk of contracting it its not just a 30 or 40people trial to lead us to a solution in the meantime experts are hopeful another type of therapy soon will be available convalescent plasma a stillexperimental treatment in which antibodies from someone who recovered from covid19 are shared via infusion despite relying on new technology modernas vaccine was rushed to phase i trials before it was tested on animals which bottazzi said is very unusual but before vaccines can be tested for efficacy they undergo even more safety testing than ordinary medicines not so with this pandemic because experts have said because production on large quantities will need to begin before having complete data tune into abc at 1 pm et and
