Active immunization with the BNT162b2 vaccine (Pfizer–BioNTech) has been a critical mitigation tool against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during disease 2019 (Covid-19) pandemic. In light of reports waning protection occurring 6 months after primary two-dose series, data are needed on safety and efficacy offering third (booster) dose in persons 16 years age or older.

Vaccination remains an important mitigation tool against COVID-19. We report 1-month safety and preliminary immunogenicity data from a substudy of ongoing, open-label, phase 2/3 study monovalent Omicron XBB.1.5-adapted BNT162b2 (single 30-μg dose). Healthy participants ≥12 years old (N = 412 (12–17 years, N 30; 18–55 174; >55 208)) who previously received ≥3 doses US-authorized mRNA vaccine, the most recent being BA.4/BA.5-adapted bivalent vaccine ≥150 days before vaccination, were...

This paper reports the fabrication and characterization of polymer nanofibers embedded with gold nanorods in uniaxial alignment for applications optical waveguiding sensing. Using a approach, we demonstrated highly efficient excitation localized surface plasmon resonance photon-to-plasmon-conversion efficiency as high 70% single nanorod at its longitudinal wavelength. On basis nanorods, further compact humidity sensors response time 110 ms an operation power low 500 pW.

Doravirine (DOR), a novel non-nucleoside reverse-transcriptase inhibitor (NNRTI), is active against wild-type Human Immunodeficiency Virus (HIV)-1 and the most common NNRTI-resistant variants, has favorable unique in vitro resistance profile. DRIVE-AHEAD phase 3, double-blind, non-inferiority trial. Antiretroviral treatment–naive adults with ≥1000 HIV-1 RNA copies/mL were randomized (1:1) to once-daily, fixed-dose DOR at 100 mg, lamivudine 300 tenofovir disoproxil fumarate (TDF) mg...

Terahertz (THz) waves, especially those assisted by THz metamaterials, have great potential for detecting trace amounts of sensing targets. Some nanomaterials, such as gold nanoparticles (AuNPs), also show promising characteristics; however, their application in this context is hindered a lack plasmonic activity the region. This study first to introduce AuNPs into metamaterial applications new tool improving sensitivity protein detection. We demonstrate mechanism detection through different...
