This article examines Covid-19 case and death rates among recipients of one of three FDA-approved vaccines. The data show that protection from infection attributable to the BNT162b2 and mRNA-1273 vaccine recipients and from death among older BNT162b2 recipients wanes over 6 months, whereas case and death rates among recipients of the Ad26.COV2.S vaccine are higher overall without a consistent pattern of waning immunity.
states has been reduced from 37 to 13 (2). Increased hepatitis A vaccination coverage, particularly through implementation of successful, nontraditional vaccination strategies among disproportionately affected populations (5), is needed to continue progress in halting current outbreaks and preventing similar outbreaks in the future.Health departments investigated HAV infections among persons who met the Council of State and Territorial Epidemiologists' hepatitis A case definition † using statespecific case investigation forms. Deidentified demographic, risk factor, and clinical outcome data were requested from all states reporting outbreaks for all outbreak-associated cases during August 1, 2016-December 31, 2020.
