Know what would be way more effective than a vaccine? Tell everybody to go out and get enough food and medicine for two weeks. Supply MRE's and drinking water for people too poor or unable to get out to shop. Then have an absolute lockdown for two weeks. No "essential worker" exceptions, other that first responders. All businesses close for two weeks. The only people on the streets are cops, firemen, and utility repair crews.

The pandemic would be over. After that two weeks we could all go back to work, play, bars, restaurants, casual sex, etc. But cops would have to arrest and jail people who evaded quarantine. They also need to do the same in jails and prisons. Segregate people who are contagious using those spit test strips. Same in nursing homes, mental hospitals, and any place where people are forced together.
