I read they have a few SARS vaccines, but non that have gone through human trials yet. Side not: I'm always concerned when we're put in a situation like this where we're pressured to put out a vaccine quickly because it opens the door for a less than optimal solution to become a mainstay. For example since it's an emergency you may put forward a solution, have it go through human trials, find some side effect, but given the current circumstance say that it's "good enough" and give it the green light of approval. Now I understand that in such an urgent circumstance that this may be justified, but after the urgency is over it's my understanding that this solution that may or may not be approved under regular circumstances will remain approved.
