If there’s no vaccine found then maintaining the R ratio below but near 1 would achieve so called herd immunity in a short amount of time if the claim at the vast majority of people show no symptoms at all is true.
If you had R at 0.5 and maintained that the infection rate would reduce to zero before it hit 80% of the population. Say there’s a million people with it currently - they’d infect half a million - then quarter of a million - 125k - 64k - and so forth until there’s no infections in the population. However maintaining R at 0.5 would be challenging without considerable restrictions - greater than those proposed in England for the next few weeks.
