Monkeys did well even when exposed to Covid-19 in large amounts. Human trials look promising. Professor Sarah Gilbert, project lead, gave the vaccine to her 21 year old triplets, who are biochemists. So, she seems to believe in her vaccine. We are vaccine skeptics and Oxford skeptics, but this looks hopeful. 🍀 For this vaccine, the research apparently came first and then a pharma company was sought, and not vice versa.

This excerpt is very important as some vaccines for SARS-CoV (this is SARS-CoV-2) made the disease worse:
In rhesus macaques, a single vaccination with ChAdOx1 nCoV-19 induced humoral and cellular immune responses. Protection against lower respiratory tract infection was observed in vaccinated non-human primates after high-dose SARS-CoV-2 challenge” Rhesus macaques are monkeys; “challenge” means that they were exposed (to high doses) of Covid-19. A chimp cold virus (chimp adenovirus) is used as a sort of carrier, rather than a human cold virus, as in some proposed Covid-19 vaccines.
