While encouraging Americans 65 years old and over, those with underlying medical conditions and frontline workers who received Pfizer's Covid-19 vaccine to get booster shots now, President Biden also said people who received Moderna and Johnson & Johnson vaccines that they still have "a high degree of protection."
"Our doctors and scientists are working day and night to analyze the data from those two organizations on whether and when you need a booster shot, and we'll provide updates for you as the process moves ahead," Biden said in an address from the White House.
"Again, the bottom line is if you're fully vaccinated, you're highly protected from severe illness, even if you get Covid-19," he said.
