Published: February 2024

The Delta pandemic wave saw increased maternal morbidity and mortality compared to prior viral strains. COVID-19 vaccination in pregnancy elicits detectable levels of neutralizing antibodies to SARS-CoV-2 wild type and SARS-CoV-2 Delta variants in both maternal and neonatal samples at delivery. Our results demonstrate the effectiveness of vaccination which confers an immunological response against newer, and potentially more dangerous, viral variants.

This study introduces a five-compartment model to account for the impacts of vaccination-induced recovery and nonlinear treatment rates in settings with limited hospital capacity. To reflect real-world scenarios, the model incorporates multiple reinfections in both vaccinated and recovered groups. It reveals a range of dynamics, including a disease-free equilibrium and up to six endemic equilibria.

Households are a significant source of SARS-CoV-2 transmission, even during periods of low community-level spread. Comparing household transmission rates by SARS-CoV-2 variant may provide relevant information about current risks and prevention strategies. This investigation aimed to estimate differences in household transmission risk comparing the SARS-CoV-2 Delta and Omicron variants using data from contact tracing and interviews conducted from November 2021 through February 2022 in five U.

This study aims to analyze the diagnostic readiness to Covid-19 and the genomic surveillance of SARS-CoV-2 in Brasília, the capital of Brazil. This is a retrospective, cross-sectional study, with data from: cases/deaths-Ministry of Health; RT-PCR analyses Brasília Central Public Health Laboratory (LACEN); genomics-Global Initiative on Sharing All Influenza Data (GISAID). It was found that in March 2021, with the Gamma variant was predominant, RT-PCR diagnostic tests administered by LACEN reached their peak, followed by a reduction, possibly due to the start of vaccination.

Randomised trial of same vs opposite arm co-administration of inactivated influenza and SARS-CoV-2 mRNA vaccines.

JCI Insight

Department of Microbiology and Immunology, Peter Doherty Institute for Infection and Immunity, University of Melbourne, Melbourne, Australia.

Background: The immunogenicity of current influenza vaccines need improvement. Inactivated influenza and COVID-19 mRNA vaccines can be co-administered but randomized controlled trial data is lacking on whether the two vaccines are more immunogenic if given in the same or opposite arms. Murine studies suggest mRNA vaccines can adjuvant influenza vaccines when co-formulated and delivered together.

Unraveling the Use of Disinformation Hashtags by Social Bots During the COVID-19 Pandemic: Social Networks Analysis.

JMIR Infodemiology

January 2025

Computational Social Science DataLab, University Institute of Research for Sustainable Social Development (INDESS), University of Cadiz, Jerez de la Frontera, Spain.

Background: During the COVID-19 pandemic, social media platforms have been a venue for the exchange of messages, including those related to fake news. There are also accounts programmed to disseminate and amplify specific messages, which can affect individual decision-making and present new challenges for public health.

Objective: This study aimed to analyze how social bots use hashtags compared to human users on topics related to misinformation during the outbreak of the COVID-19 pandemic.
