Who is not vaccinated in the US and what's the risk?

US President Joe Biden has urged Americans to get jabbed, saying the unvaccinated "have a significantly higher risk of ending up in hospital, or even dying".

"Almost everyone who has died from Covid-19 in the past many months has been unvaccinated," he told Americans on Tuesday.

About six in ten Americans are fully vaccinated, but in some states it's fewer than that.

Case and death rates for people who are not vaccinated are higher in the US than for those fully vaccinated, according to data collected by the US Centers for Disease Control (CDC).
