Covid will be in our rear view mirror before a vaccine is safe, ready, mass produced and easily distributed. Herd immunity is not terribly far away in most countries and by the spring the threshold should be reached nearly everywhere. A vaccine won't be necessary and even if available isn't likely to be taken by most people, as covid has lower IFR than the flu for people under 50 (and magnitudes lower under 20).
