An elderly patient contracts influenza; high viral load overwhelms the initial interferon response. Which consequence follows regarding adaptive immunity?

💡 Explanation

A high viral load causing overwhelming interferon response delays T-cell activation and clearance because antigen presentation to T-cells becomes inefficient. This inefficiency is due to resource competition, therefore T-cell mediated clearance is delayed, rather than accelerated antibody production or complement hyperactivity, which depend on initial T-cell help.
