It seems unimaginable that a vaccine against covid19 vaccine would not eventually be developed. It appears to be matter of when rather than if. Over a hundred labs are working on this project around the world. Labs are trying a mix of different types, mostly mRNA, DNA, VLP( virus like particle ), protein subunit , recombitant viral vector ( mostly adenovirus...some bacterial )etc. The last time we witnessed such a vaccine race was to combat Ebola fever. Eventually the first and only licenced vaccine was Erbevo developed by Public Health Canada, a recombitant viral vector vaccine using VSV ( vescicular stomatitis virus ) as vector. CanSino (Canadian/Chinese collaboration) and Oxford University / Astra Zeneca are both developing adenovirus vector vaccines both entering phase two trials, the most advanced in trials at the moment. In Canada, University of British Columbia is developing a DNA vaccine with bacterial vector vaccine which will be consumed as a probiotic tablet while Medicago i...
