Alex Huffman, an aerosol scientist and professor at the University of Denver. ![]() Getting vaccinated against the virus is a lot like applying sunscreen while vacationing at the beach, said Dr. It’s important to remember that occasional breakthroughs are expected with any vaccine. “You can’t control a pandemic when 30 percent or even half the people are immunized,” he said. #Facebook warns to decelerate mandates vaccine full#And in some pockets of the country, fewer than a third of people have received full vaccine protection. With only about half of the nation’s population - 163.3 million people - fully vaccinated against the coronavirus, the vaccine’s advantages begin to erode, said Weissman, a physician and infectious disease expert at the University of Pennsylvania. That means the delta variant is more efficient at spreading and every time an infected person coughs, sneezes or speaks, they potentially release much more of the virus - and opportunities to get someone else sick - than earlier in the pandemic. When people are infected with the delta variant, Huffman said they produce a thousand times greater viral load than seen from the original COVID-19 strain. Mounting research suggests the variants are placing greater strain on the vaccines. Drew Weissman, who spent nearly two decades conducting research that led to the development of the mRNA vaccines manufactured by Pfizer and Moderna to stop the coronavirus. The amount of breakthrough cases we’re seeing actually suggest that the vaccines “are still working great,” but too much is being asked of them, said Dr. Instead, they are a warning of how vaccine holdouts can endanger even their inoculated neighbors. As the delta variant makes a deadly sweep through unvaccinated communities, renewing calls for masks and vaccine mandates, health experts say that rare “breakthrough infections” among vaccinated people are not a sign that vaccines are failing. ![]()
