President Joe Biden made a comment on Monday on the government’s Covid-19 measures and vaccination efforts across the country.

Biden’s remarks come just hours after the director of the Centers for Disease Control and Prevention Dr. Rochelle Walensky had given reporters a grim warning. She said she was concerned that the US was facing “impending doom” as daily Covid-19 cases rise again and threaten to send more people to hospital even as vaccinations increase across the country.

U.S. health officials are urging Americans to get vaccinated as soon as possible while following pandemic safety measures.

A CDC study of health care workers and other key workers published Monday found that Pfizer and Moderna’s Covid-19 vaccines were 80% effective against coronavirus infections two weeks after a single dose. Two doses were better than one, with vaccines effectiveness increasing to 90% two weeks after the second dose, the agency found.
