Singapore is surging. We will have multiple “Singapores” here in the US. Their surge is higher than any they’ve had. 83% fully vax’d @ the time of this graph.

Does this look like u can’t surge if u have a significant amount of vax in your country or state? US is 57% fully vax’d. Image What say you? But is it impacting their healthcare services? YES. “Singapore ministers told a media briefing on Friday that the jump in COVID-19 cases in the island of 5.7 million people had put ‘tremendous’ pressure on its healthcare system.”
