CLEVELAND, Ohio (WOIO) - About one in 10 Americans have now received at least one dose of the vaccine.
Across the U.S., the race against coronavirus variants continues.
Are COVID-19 shots needed every year?
Experts are now suggesting the need for a Covid-19 shot every year, like flu shots.
The CEO of Johnson & Johnson, one of the vaccine makers, said virus mutations may mean an annual Covid shot will be needed for years to come.
Second dose timeline changes
The CDC has released new guidelines for the second dose of the Covid-19 vaccine.
The agency says the second shot can be scheduled up to 42 days after the first shot.
The Pfizer shots are typically given 21 days apart and 28 days apart for the Moderna vaccine.
New quarantine guidelines
The CDC is changing its quarantine recommendations for Americans who have been fully vaccinated against Covid-19.
The agency now says they do not have to quarantine if they’re exposed to someone who is infected.
This applies to people who received two doses of the Pfizer or Moderna vaccine.
The CDC says two weeks must have passed since the final dose.
