China has a strict 0 tolerance policy that is taking an economic toll as the pandemic is now in its third year. If the lockdowns prove effective they may continue until the pandemic is completely over but such restrictions would prove untenable in this nation. That leaves America relying on vaccines to halt the next surge that seems more inevitable every day.
