Core Concepts
Protecting essential workers from SARS-CoV-2 reinfection requires vaccination, mask use, and addressing health disparities.
Abstract
Abstract:
Risk factors for reinfection in previously infected essential workers.
Factors include vaccination status, mask use, time since first infection, and ethnicity.
Multipronged approach needed for protection.
Introduction:
Essential workers face repeated exposure to SARS-CoV-2.
Omicron variant increased reinfections.
Protection from previous infection waned with Omicron.
Vaccine effectiveness against Omicron lower than previous variants.
Study aims to identify risk factors for reinfection in essential workers.
Stats
"mRNA vaccine effectiveness against first-time Omicron infections were lower (46% after 2 doses and 60% after 3 doses)."
"Risk reduction for hospitalization related to reinfection with Omicron was 35% with 2 doses of mRNA vaccine and 68% with 3 doses."
Quotes
"Protecting workers from reinfection requires a multipronged approach including up-to-date vaccination, mask use as recommended, and reduction in underlying health disparities."
