Are Covid-19 Vaccine Boosters Needed? The Science Behind Boosters, Rachel M. Burckhardt, John J. Dennehy, Leo L. M. Poon, Linda J. Saif, Lynn W. Enquist

Publications and Research

Waning vaccine-induced immunity coupled with the emergence of SARS-CoV-2 variants has led to increases in breakthrough infections, prompting consideration for vaccine booster doses. Boosters have been reported to be safe and increase SARS-CoV-2-specific neutralizing antibody levels, but how these doses impact the trajectory of the global pandemic and herd immunity is unknown. Information on immunology, epidemiology and equitable vaccine distribution should be considered when deciding the timing and eligibility for COVID-19 vaccine boosters.

An Evolutionary Vaccination Game In The Modified Activity Driven Network By Considering The Closeness, Dun Han, Mei Sun

Publications and Research

In this paper, we explore an evolutionary vaccination game in the modified activity driven network by considering the closeness. We set a closeness parameter p which is used to describe the way of connection between two individuals. The simulation results show that the closeness p may have an active role in weakening both the spreading of epidemic and the vaccination. Besides, when vaccination is not allowed, the final recovered density increases with the value of the ratio of the infection rate to the recovery rate λ/μ. However, when vaccination is allowed the final density of recovered individual first increases and …

Environmental Data Analysis And Remote Sensing For Early Detection Of Dengue And Malaria, Md Zahidur Rahman, Leonid Roytman, Abdelhamid Kadik, Dilara A. Rosy

Publications and Research

Malaria and dengue fever are the two most common mosquito-transmitted diseases, leading to millions of serious illnesses and deaths each year. Because the mosquito vectors are sensitive to environmental conditions such as temperature, precipitation, and humidity, it is possible to map areas currently or imminently at high risk for disease outbreaks using satellite remote sensing. In this paper we propose the development of an operational geospatial system for malaria and dengue fever early warning; this can be done by bringing together geographic information system (GIS) tools, artificial neural networks (ANN) for efficient pattern recognition, the best available ground-based epidemiological and …

Epidemiology Of Undiagnosed Trichomoniasis In A Probability Sample Of Urban Young Adults, Susan M. Rogers, Charles F. Turner, Marcia Hobbs, William C. Miller, Sylvia Tan, Anthony M. Roman, Elizabeth Eggleston, Maria A. Villarroel, Laxminarayana Ganapathi, James R. Chromy, Emily Erbelding

T. vaginalis infection (trichomoniasis) is the most common curable sexually transmitted infection (STI) in the U.S. It is associated with increased HIV risk and adverse pregnancy outcomes. Trichomoniasis surveillance data do not exist for either national or local populations. The Monitoring STIs Survey Program (MSSP) collected survey data and specimens which were tested using nucleic acid amplification tests to monitor trichomoniasis and other STIs in 2006–09 among a probability sample of young adults (N = 2,936) in Baltimore, Maryland — an urban area with high rates of reported STIs. The estimated prevalence of trichomoniasis was 7.5% (95% CI 6.3, 9.1) …

Antibodies Elicited In Response To Ebna-1 May Cross- React With Dsdna, Pragya Yadav, Hoa Tran, Roland Ebegbe, Paul Gottlieb, Hui Wei, Rita H. Lewis, Alice Mumbey-Wafula, Atira Kaplan, Elina Kholdarova, Linda Spatz

Background:Several genetic and environmental factors have been linked to Systemic Lupus Erythematosus (SLE). One environmental trigger that has a strong association with SLE is the Epstein Barr Virus (EBV). Our laboratory previously demonstrated that BALB/c mice expressing the complete EBNA-1 protein can develop antibodies to double stranded DNA (dsDNA). The present study was undertaken to understand why anti-dsDNA antibodies arise during the immune response to EBNA-1.

Methodology/Principal Findings: In this study, we demonstrated that mouse antibodies elicited in response to EBNA-1 cross-react with dsDNA. First, we showed that adsorption of sera reactive with EBNA-1 and dsDNA, on dsDNA cellulose …
