I agree that vaccines are effective, but we still need to stop the spread.
Perhaps we are going to face another COVID surge during holiday season. I guess a 4th dose of vaccine will be only be a matter of time. The houses in America are actually better suited for a lockdown policy than the apartment halls in China, but it seems people here in America just cannot stop the spread. Honestly, I don’t think the virus will magically disappear if people keep doing things half-mindedly.
