An updated briefing, prepared by Battelle, looks at research available on vaccines, variants, and ventilation. This research focused on three key questions:
- What implications does SARS-CoV-2 vaccination in the United States have for public health interventions and policies, especially related to indoor environments?
- What differences have been found for SARS-CoV-2 variants (compared to the original strain) in the United States in terms of spread, transmissibility, surface attenuation, and effectiveness of public health interventions?
- What effects do ventilation and ventilation-based interventions (e.g., heating, ventilation, and air conditioning systems [HVAC]) have on the spread of SARS-CoV-2 in indoor environments?
