For herd immunity, the number discussed is 80% of the population getting Covid-19. Since there are cases world-wide, I don't see containment at this point working. To even consider containment succeeding, we would need a way to test 300 million people a couple times a week. Since we can't do even 1 million tests a day, the math doesn't add up. "Giving up" is a strange way to look at it. We have various flus annually. There will be a time limit to lockdown of several weeks, not 18 months. So it's important to look at the data and make an informed public healthcare policy decision.
