A stark difference is emerging in how Americans are combatting the Omicron variant, compared to officials in Canada. While Canadians deal with a long list of new restrictions and warnings to avoid holiday gatherings, President Biden has told vaccinated Americans they can enjoy Christmas safely. His Omicron plan includes sending 1,000 troops to overwhelmed hospitals sending 500 million tests to American homes amid a nationwide shortage and with lines forming at testing centers. Biden spoke after Dr. Fauci warned Omicron is spreading at an unprecedented rate and cases across the U.S. could double every two days. “If you’re not fully vaccinated, you have good reason to be concerned,” Biden said, with studies showing the unvaccinated have virtually no immunity against Omicron. Biden also said it can be hard to get an appointment for covid testing – coughing into his hand as he made the point, as well as at another point during his remarks. But he snapped when asked a question about experts who have advised for months that the nation needed a surge of testing, and whether it was a failure that they weren’t available. “No, it’s not. Because COVID is spreading so rapidly – notice it just happened almost overnight, just in the last month,” he said.
