Evaluating Humoral Immunity Elicited by XBB.1.5 Monovalent COVID-19 Vaccine
We report boosting of IgG (2.1×), IgA (1.5×), and total IgG/A/M (1.7×) targeting the spike receptor-binding domain and neutralizing titers against WA1 (2.2×), XBB.1.5 (7.4×), EG.5.1 (10.5×), and JN.1 (4.7×) variants.PMID:38669121 | DOI:10.3201/eid3006.240051 (Source: Emerging Infectious Diseases)

Interventional Study of Nonpharmaceutical Measures to Prevent COVID-19 Aboard Cruise Ships
Emerg Infect Dis. 2024 May;30(5):1030-1033. doi: 10.3201/eid3005.231364.ABSTRACTCruise ships carrying COVID-19-vaccinated populations applied near-identical nonpharmaceutical measures during July-November 2021; passenger masking was not applied on 2 ships. Infection risk for masked passengers was 14.58 times lower than for unmasked passengers and 19.61 times lower than in the community. Unmasked passengers' risk was slightly lower than community risk.PMID:38666667 | DOI:10.3201/eid3005.231364 (Source: Emerging Infectious Diseases)

COVID-19 Vaccination Site Accessibility, United States, December 11, 2020-March 29, 2022
Emerg Infect Dis. 2024 May;30(5):947-955. doi: 10.3201/eid3005.230357.ABSTRACTDuring December 11, 2020-March 29, 2022, the US government delivered ≈700 million doses of COVID-19 vaccine to vaccination sites, resulting in vaccination of ≈75% of US adults during that period. We evaluated accessibility of vaccination sites. Sites were accessible by walking within 15 minutes by 46.6% of persons, 30 minutes by 74.8%, 45 minutes by 82.8%, and 60 minutes by 86.7%. When limited to populations in counties with high social vulnerability, accessibility by walking was 55.3%, 81.1%, 86.7%, and 89.4%, respectively. By driving, lowes...

Nutritional status and its relationship with COVID-19 prognosis in hemodialysis patients
CONCLUSIONS: higher body mass index and higher body fat content, along with lower baseline levels of triglycerides and ferritin, are significantly associated with higher COVID-19 mortality in patients on chronic hemodialysis. These findings suggest that the initial nutritional status of these patients can significantly influence the prognosis of SARSCoV-2 infection.PMID:38666342 | DOI:10.20960/nh.04850 (Source: Nutricion Hospitalaria)

Analysis of new-onset seizures following use of COVID-19 vaccinations in children based on VAERS
CONCLUSION: No statistically significant risk signal of COVID-19 vaccine-related seizures was found in this study. However, it is still necessary to monitor the possibility of new-onset seizures when children are immunized with COVID-19 vaccines.PMID:38666296 | DOI:10.1080/14740338.2024.2348568 (Source: Expert Opinion on Drug Safety)

Procedural Dimensions of Religious Exemptions to Covid-19 Vaccine Mandates: Promoting Clarity, Fairness, and Transparency in Applications
This study examines the procedural ethical considerations surrounding religious exemptions to Covid vaccine mandates, specifically focusing on immigrant healthcare personnel (HCP) and HCPs of color. It emphasizes communication issues with applicants by investigating exemption applications and their accompanying guidelines. While there is extensive literature on the ethical implications of religious exemptions, a notable gap remains in addressing the procedural aspects of religious exemption applications and their reviewing processes. The study scrutinized religious exemption application forms and accompanying guidelines fr...

A programmatic update on COVID-19 vaccination in rural communities in the United States
Vaccine. 2024 Apr 25:S0264-410X(24)00469-9. doi: 10.1016/j.vaccine.2024.04.043. Online ahead of print.ABSTRACTWhen public health experts think of rural barriers to vaccines, they often initially focus on access, which makes sense with a new vaccine during a pandemic. This commentary highlights that there can be more complexity to vaccine uptake in rural communities. What follows are some examples of CDC's efforts to better understand rural health and learnings to inform ongoing vaccination efforts in rural communities.PMID:38670846 | DOI:10.1016/j.vaccine.2024.04.043 (Source: Vaccine)

COVID-19 booster vaccine uptake and reduced risks for long-COVID: A cross-sectional study of a U.S. adult population
This study examined associations between booster uptake and long-COVID prevalence among U.S. adults. Data were analyzed from 8757 adults aged 18 years or older with a history of COVID-19 infection from the 2022 National Health Interview Survey. Weighted prevalence and logistic regression models examined relationships between self-reported COVID-19 booster vaccination status and long-COVID, adjusting for sociodemographics and health factors. 19.5 % reported experiencing long-COVID. Individuals receiving the COVID-19 booster vaccine had significantly lower adjusted odds of long-COVID (OR 0.75, 95 % CI 0.61-0.93) compared to ...

Seroprevalence of anti-SARS-CoV-2 in patients with hepatitis B and C: a pre-vaccination study
This study aims to assess the prevalence of anti-SARS-CoV-2 in hepatitis B and C patients in a pre-vaccination of COVID-19 period. Between March 2020 and January 2021, 199 serum samples from individuals with HBsAg/HBV DNA or anti-HCV/HCV RNA positivity were tested for antibodies (IgM and IgG) against SARS-CoV-2 using Electrochemiluminescent Immunoassay (ECLIA). Among these, 50.3 % (100/199) tested positive for hepatitis C virus infection and 49.7 % (99/199) for hepatitis B virus, confirmed through molecular and serological diagnosis. The anti-SARS-CoV-2 seroprevalence was 24.1 % (48/199) in this population, with 23.23 % (2...
