Background: Recombinant influenza vaccine (RIV) has been in use in US adults since 2013. This study evaluated the safety of quadrivalent recombinant influenza vaccine (RIV4, Flublok® Quadrivalent, Sanofi Pasteur) compared with standard-dose quadrivalent inactivated influenza vaccine (SD-IIV4) in self-identified Chinese adults at Kaiser Permanente Northern California (KPNC).
Methods: This study evaluated adults aged 18-64 years within KPNC during the 2018-2019 influenza season who self-identified as Chinese (NCT03694392).
Objectives: To compare rates of myopericarditis, severe and serious dermatological or neurological events, and other adverse events in deploying US military personnel who received or did not receive ACAM2000® (Smallpox [Vaccinia] Vaccine, Live) vaccine and to evaluate potential risk factors for development of myopericarditis.
Methods: Prospective observational cohort study enrolling up to 15,000 ACAM2000 recipients (Cohort 1) and up to 5000 persons otherwise eligible for ACAM2000 vaccination but not vaccinated due to recency of vaccination or characteristics of their contacts (Cohort 2). Data and specimens were collected initially and 10 (6-17) days later.
Background: To understand the clinical burden of infection (CDI), we analyzed health outcome data from Ontario, Canada for CDI associated with and manifested in acute care hospitals (ACH), long-term care facilities (LTCF), the community, or ACH-associated with community-onset.
Methods: We performed a retrospective analysis using individual-level data from Ontario databases (April 1, 2005 to March 31, 2015), identifying CDI cases ≥18 years requiring hospitalization, and stratifying into cohorts based on association and onset location. Cohort members were matched to controls on demographics and medical conditions at onset, for outcomes including 30- and 180-day all-cause mortality and rehospitalization.
Background: Understanding the impact of prevention programs on infection rates is important, and decisions on future program changes, including how to use vaccines currently in development, requires a detailed understanding of the epidemiologic features of infection. We analyzed Ontario health administrative data to determine incidence rates and medical costs of infection, based on whether acquisition and onset occurred in acute care hospitals (ACHs), long-term care facilities or the community.
Methods: We performed a retrospective analysis using individual-level data from Ontario health databases from Apr.
Rationale: Pilot study results suggested that a new form of nicotine oral soluble film relieved smoking cue-provoked acute craving faster than nicotine lozenge or gum. The new nicotine film may provide smokers another choice to relieve acute craving.
Objectives: This study compared the efficacy of the 2.
