Dr. Robert Bollinger: "Such fast development of tests and vaccines are a clear example of the collaboration between scientists and the importance of public investment."
Dr. Bollinger: "People getting infected now are a lot younger than they were with the earlier variants, because the older people are vaccinated at a much higher rate."
Dr. Matt Robinson: "It makes it easier for clinicians to anticipate what will happen to patients and helps them focus on patients who are the sickest."
