The 60% figure comes from an R0 (basic reproduction number) of 2.5. But, if you have 20% of people immune (as with some hard-hit areas in Italy, for example) the Reff would still be reduced quite a bit

The disease won't stop spreading on its own, but in combination with a relatively small number of interventions (say, masks and no large gatherings) it might not spread very far if 1 in 5 people have already had COVID-19
