A month and a half or two months ago, we were told by those in charge and the experts that, thanks to the vaccine, the pandemic was basically over. We could lose our masks, gather indoors, travel, hug our loved ones, and enjoy the summer. Now we are struggling to control the pandemic again, running out of hospital beds, seeing people die and all that. Leaders and experts are begging people to wear masks, social distance, and everything else. This raises two questions. Why did civic leaders and experts give such bad advice a couple of months ago? And why would anyone accept, “We didn’t understand the Delta variant like we do now,” as a valid excuse? I’m struggling to understand.
