The virus triggers an acute immune response. This is not the same as an autoimmune disease, it may be the opposite. Also, people with certain blood types that have better clotting ability seem to be at a disadvantage.
While I would not trust someone posting here on HN about medical advice, I would trust doctors from around the world who have stated that, for example, hydroxychloroquine is not recommended for use against SARS-CoV-2, and I would absolutely trust them over any poster here and any politician.
More to your point: there may be potential solutions that are not a vaccine but I'll trust researchers and doctors to find those solutions, rather than doing the investigation myself, as they are much more highly trained than I ever will be on the subject.
