On Wednesday, Pfizer and BioNTech announced that preliminary lab studies show a third dose of the Pfizer/BioNTech vaccine can improve protection against Omicron.
The finding was not surprising to Dr. Leana Wen, emergency physician and visiting professor of health policy and management at the George Washington University Milken Institute School of Public Health.
