My personal take, no expertise, just reading articles I don't think we will have a vaccine in 5 years much less 18 months. It sounds really hard to vaccinate against this one, even without it mutating, which is sounds like it mutates pretty quickly.

Recently lots of articles and chatter that the core of the issues is that it is causing are mostly blood clotting related. Sounds like existing blood thinners aren't working, so it sounds promising that they could develop new blood thinners as possible treatments.

I agree, I'm not signing up for a rushed vaccine that might not be effective and could have negative long term side affects.
