The story starts, we believe, with a noble goal: to prevent the world from ever having the type of pandemic we are currently experiencing, through production of a vaccine effective against all coronaviruses past and future.
Coronavirus vaccines can be difficult to make. In animals, while vaccines are sometimes successful, toxicity of the vaccine as well as incomplete immunity can happen. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7284272/ .
SARS-CoV-2 (COVID19) is a lot like SARS-CoV (SARS). SARS initially hit China and East Asia in 2003, killed 774 people, infected over 8000, and scared everyone. For the past 17 years there has been an enormous effort worldwide to develop a vaccine not only against SARS but also against all coronavirus strains. As we have detailed in another post, scientists knew in 2006 that recombinant spike protein RBD vaccines to SARS didn’t protect all animals from a re-challenge from a slightly different mutated coronavirus ( https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7124095/pdf/978-0-387-33012-9_Chapter_101.pdf ). Young animals can gain immunity, but it can be harder to get protective immunity in older animals ( https://pubmed.ncbi.nlm.nih.gov/17194199/ ). .......
