Wasn't Singapore supposed to be one of the few success stories for eliminating Covid-19 without using vaccination, one of the countries that supposedly proved Western countries like the US could've avoided the need for economy-destroying lockdowns if only their governments were competent? Not to mention that they were and still are one of the most aggressive about mandating mask wearing, and were pointed to as a demonstration of how effective that was as well. The idea that Singapore going into lockdown proves the US CDC was wrong to advise vaccinated people don't need to wear masks seems extremely dubious.
