Consumers benefit from reduced severe illness and death risk, supporting continued vaccination uptake and healthcare spending. Moderate symptomatic infection prevention (48%) may increase out-of-pocket costs for testing and treatment among breakthrough infections.
Supports continued government vaccine procurement and distribution programs. May influence public health messaging and vaccination campaign funding. Could prompt regulatory review of vaccine development timelines for variant-specific formulations. May impact healthcare resource allocation and pandemic preparedness budgets.
