How COVID-19 Vaccines Work

Immune response: Vaccines train the immune system to recognize SARS-CoV-2 and mount a rapid defense.
Platforms: mRNA (Pfizer, Moderna), protein-based (Novavax), and adenovirus-vectored vaccines remain widely used.
Boosters: Updated formulations target newer variants like JN.1, improving protection against circulating strains.

Effectiveness in 2025–2026

Hospitalization Protection: Updated vaccines reduced hospitalizations by ~55% among adults with COVID-like illness.
Emergency Care Visits: Effectiveness against ED/urgent care visits was ~50%, showing strong real-world impact.
Variant Adaptation: Omicron-adapted boosters provide superior protection compared to older monovalent doses.
