Can be done even before anti virus vaccine is developed. One is fast test, ie, get results within 5 mins or less and tests are readily available to deploy around airports and malls, office lobbies etc. Second is to have anti-body tests to test everyone's ability to resist the virus. This is to increase self-confidence.Anyone with an IQ in the set of positive integers will not stop social distancing until a vaccine is developed and has been deployed.
Of course anti virus vaccine is the ultimate solution, but it can be a while.
