As with most endemic viruses though, unless you hit a level of herd immunity you don't "get rid of it".
It continues on in humans without immunity who may not show symptoms and in animal reservoirs (minks, ferrets etc seems to be the case for COVID).
Unless we inoculate children as well as adults we are unlikely to hit herd immunity (based on the values thrown around of needing 85-95% coverage for an 80% efficacy vaccine)
- bpodgursky 6y agoBased on low in-school transmission rates, it's not obvious that the disease has a natural R > 1.0 among children (likely, because there is strong evidence that asymptomatic cases, which children generally get, have low transmission).
- bluGill 6y agoVaccines for children are in study phases now and expected late this year (for 12+, next year for the next group). Of course we need herd immunity, but signs are showing it is possible. The animal reservoirs are a real concern though.
