Real-world evaluations have demonstrated high effectiveness of vaccines against COVID-19-associated hospitalizations (1-4) measured shortly after vaccination; longer follow-up is needed to assess durability protection. In an evaluation at 21 hospitals in 18 states, the duration mRNA vaccine (Pfizer-BioNTech or Moderna) (VE) was assessed among adults aged ≥18 years. Among 3,089 hospitalized (including 1,194 COVID-19 case-patients and 1,895 non-COVID-19 control-patients), median age 59 years,...
Health care personnel (HCP) caring for patients with coronavirus disease 2019 (COVID-19) might be at high risk contracting SARS-CoV-2, the virus that causes COVID-19. Understanding prevalence of and factors associated SARS-CoV-2 infection among frontline HCP who COVID-19 are important protecting both their patients. During April 3-June 19, 2020, serum specimens were collected from a convenience sample worked 13 geographically diverse academic medical centers in United States, tested...
Most persons infected with SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), develop virus-specific antibodies within several weeks, but antibody titers might decline over time. Understanding timeline of is important for interpreting SARS-CoV-2 serology results. Serum specimens were collected from a convenience sample frontline health care personnel at 13 hospitals and tested to during April 3-June 19, 2020, again approximately 60 days later assess this timeline. The...
COVID-19 mRNA vaccines (BNT162b2 [Pfizer-BioNTech] and mRNA-1273 [Moderna]) provide protection against infection with SARS-CoV-2, the virus that causes COVID-19, are highly effective COVID-19-associated hospitalization among eligible persons who receive 2 doses (1,2). However, vaccine effectiveness (VE) immunocompromising conditions* is lower than immunocompetent (2), VE declines after several months all (3). On August 12, 2021, Food Drug Administration (FDA) issued an emergency use...
The SARS-CoV-2 Omicron variant (B.1.1.529 or BA.1) became predominant in the United States by late December 2021 (1). BA.1 has since been replaced emerging lineages BA.2 (including BA.2.12.1) March 2022, followed BA.4 and BA.5, which have accounted for a majority of infections June 2022 Data on effectiveness monovalent mRNA COVID-19 vaccines against BA.4/BA.5-associated hospitalizations are limited, their interpretation is complicated waning vaccine-induced immunity (2-5). Further, with...
Abstract Introduction Understanding the changing epidemiology of adults hospitalized with coronavirus disease 2019 (COVID-19) informs research priorities and public health policies. Methods Among (≥18 years) laboratory-confirmed, acute COVID-19 between 11 March 2021, 31 August 2022 at 21 hospitals in 18 states, those during severe respiratory syndrome 2 (SARS-CoV-2) Omicron-predominant period (BA.1, BA.2, BA.4/BA.5) were compared to from earlier Alpha- Delta-predominant periods. Demographic...
Influenza circulation during the 2022-2023 season in United States largely returned to pre-coronavirus disease 2019 (COVID-19)-pandemic patterns and levels. A(H3N2) viruses were detected most frequently this season, predominately clade 3C.2a1b.2a, a close antigenic match vaccine strain.
This paper presents a novel corrosion-based energy harvester designed for long-term operational deployments in marine infrastructure monitoring. A statistical approach is utilized to characterize the output power, and results are applied as basis designing complimentary low-power sensor node. Furthermore, analyses performed on node operation ensure robust over range of design environmental parameters. concludes with method estimating volumetric size active component by analyzing power...
Vaccine effectiveness (VE) against COVID-19 hospitalization was evaluated among immunocompetent adults (≥18 years) during March-August 2021 using a case-control design. Among 1669 hospitalized cases (11% fully vaccinated) and 1950 RT-PCR-negative controls (54% vaccinated), VE 96% (95% confidence interval [CI], 93%-98%) patients with no chronic medical conditions 83% CI, 76%-88%) ≥ 3 categories of conditions. similar between those aged 18-64 years versus ≥65 (P > .05). severe very high...
Coronavirus disease 2019 (COVID-19) vaccine effectiveness (VE) studies are increasingly reporting relative VE (rVE) comparing a primary series plus booster doses with only. Interpretation of rVE differs from traditional measuring absolute (aVE) regimen against an unvaccinated referent group. We estimated aVE and COVID-19 hospitalization in primary-series first-booster recipients vaccines.Booster-eligible immunocompetent adults hospitalized at 21 medical centers the United States during...
