Covid-19 vaccine identified by scientists:

Scientists have identified regions of the SARS-CoV-2 virus that causes Covid-19 to target with a vaccine, by harnessing tools used for the development of cancer immunotherapy. According to the researchers at the children’s hospital in Philadelphia, there is believed to be a resulting vaccine which would provide protection across the human population and drive a long-term immune response. John M Maris, a paediatric oncologist at CHOP stated that In many ways, cancer behaves like a virus, so our team decided to use the tools we developed to identify unique aspects of childhood cancers that can be targeted with immunotherapy and apply those same tools to identify the right protein sequences to target in SARS-CoV-2. An optimally designed vaccine maximises a long-lasting immune response, while minimising adverse reactions, autoimmunity, or disease exacerbation, they said. To increase the likelihood that a vaccine is both safe and effective, the research team prioritised parameters in identifying regions of the virus to target. They targeted regions of SARS-CoV-2 that are present across multiple related coronaviruses, as well as new mutations that increase infectivity, while also ensuring that those regions were as dissimilar as possible from sequences naturally occurring in humans to maximize safety. The team will now test various combinations of a dozen or so of these sequences in mouse models to assess their safety and effectiveness.
