  • Just under half of adults in the U.S. said in December they were very likely to get vaccinated, according to a new CDC study.
  • That's up from 39.4% of adults surveyed in September but still below the 70% to 85% scientists say is needed to suppress the virus.
  • That could potentially jeopardize U.S. vaccination efforts to control the pandemic, which has overwhelmed hospitals and taken more than 466,000 American lives in about a year.

Wendy Borger tested positive for Covid-19 at an urgent care center in Palmerton, Pennsylvania, on Dec. 28. She said she was fatigued, short of breath, and had a headache, heart palpitations and a fever of 103 degrees Fahrenheit. Her oxygen level dipped to 94%.

Borger, who is 50 and suffers from chronic bronchitis, said her lungs felt like a "weapon" when she walked down the stairs or even had a shower. It took almost two weeks before it didn't hurt to breathe, she said. It's been more than a month since her diagnosis, and she still isn't fully recovered.
