Unvaccinated people don’t only risk their own health: Their bodies become’variant factories’

Unvaccinated people can be a driving force for new variants, an infectious disease expert told CNN. "Unvaccinated people are potential variant factories," infectious disease expert Dr. William Schaffner said. Mutations that replicate can become variants and unvaccinated hosts more easily allow for that. LoadingSomething is loading. ...

Surging coronavirus cases and deaths in Russia show the Delta variant’s havoc on a largely unvaccinated population

Russia's daily coronavirus cases have more than doubled in the last month. Deaths are climbing, too, as the Delta variant becomes more widespread. It's a lesson in what happens when Delta strikes a mostly unvaccinated country, experts said. See more stories on Insider's business page. Nearly a year after becoming the first nation to authorize a coronavirus shot, Russia has fallen behind in the global vaccine rollout. Just 15% of its population has received at least one dose.So when Russia identified its first cases of the Delta variant in May, the threat loomed larger than in highly vaccinated countries like Israel, the US, or the ...

Has the coronavirus reached’peak fitness’? Experts wonder if the Delta variant is the worst we’ll see.

No coronavirus variant spotted so far is more concerning than Delta, the strain first identified in India in February. World Health Organization officials on Monday said Delta is the "fittest" variant to date, since it spreads even more easily than other variants and may lead to more severe cases among unvaccinated people."Delta is a superspreader variant, the worst version of the virus we've seen," Eric Topol, director of the Scripps Research Translational Institute, tweeted last week.But it's possible that Delta is the worst the coronavirus is going to throw at us — that the virus, in other words, has reached what epidemiologists call "peak fitness."Topol and Italian virologist Roberto Burioni explore that scenario in a let...

Biden says the Delta variant — set to become the US’s dominant strain — is’particularly dangerous for young people’

President Joe Biden warned Friday that Delta, a coronavirus variant first discovered in India, poses an increased threat to unvaccinated Americans."It is a variant that is more easily transmissible, potentially deadlier, and particularly dangerous for young people," Biden said at a White House news conference.His remarks came just hours after Rochelle Walensky, director of the Centers for Disease Control and Prevention, told "Good Morning America" ​​that Delta would likely become the dominant strain in the US in the coming months. (Some experts have even suggested that might even happen within weeks.)Delta represents just 10% of US COVID-19 cases so far, but it already makes up around 90% of cases in the UK, according to a st...
