Joe Biden: "Those who are not vaccinated MAY end up paying the price."

“There will be advances and setbacks” as more people are vaccinated in the US, Mr Biden said, acknowledging fluctuating rates of infections.

“But if the unvaccinated get vaccinated, they will protect themselves and other unvaccinated people around them. If they do not, states with low vaccination rates may ... see that progress reversed,” he said. “Only those who are not vaccinated will end up paying the price.”

He added: “Given that the vaccinations are free and convenient, it would be a tragedy – and a needless one – to see Covid cases among those who do not get vaccinated go up. We’re not done fighting this virus. We still have tens of millions to get vaccinated.”

About 43 per cent of the US has received at least one dose of two-shot vaccines Pfizer and Moderna or the single-shot Johnson & Johnson vaccines. More than 37 per cent of the US is fully vaccinated, according to the US Centers for Disease Control and Prevention.

Just over 50% of the CDC and FDA's staff have taken the vaccine according to Anthony Fauci, who does not have accurate figures available. 

The CDC does however have figures for teachers: Nearly 80 percent of Pre-K-12 teachers, school staff, and childcare workers received at least their first shot of COVID-19 vaccine by the end of March, according to the CDC’s latest estimates and survey data.
