@thecity2 @3Sentinel4 @youyanggu I mean yeah 20-25% is probably not enough to hit the herd immunity threshold (though estimates of the threshold range everywhere from like 20% to 70%). But lowering Rt by 20-25%, combined with half-assed measures, may be enough to make half-assed measures seem more effective. — PolitiTweet.org
