Coronavirus disease 2019 (COVID-19) is the most dramatic pandemic of the new millennium; to counteract it, specific vaccines have been launched in record time under emergency use authorization or conditional marketing authorization by virtue of a favorable risk/benefit balance. Among the various technological platforms, there is that exploiting a nucleoside-modified messenger RNA (modRNA), such as… Continue reading A Three-Case Series of Thrombotic Deaths in Patients over 50 with Comorbidities Temporally after modRNA COVID-19 Vaccination

Longitudinal multi-omics analyses link gut microbiome dysbiosis with recurrent urinary tract infections in women
Recurrent urinary tract infections (rUTIs) are a major health burden worldwide, with history of infection being a significant risk factor. While the gut is a known reservoir for uropathogenic bacteria, the role of the microbiota in rUTI remains unclear. We conducted a year-long study of women with (n = 15) and without (n = 16) history of rUTI, from… Continue reading Longitudinal multi-omics analyses link gut microbiome dysbiosis with recurrent urinary tract infections in women
Increased emergency cardiovascular events among under-40 population in Israel during vaccine rollout and third COVID-19 wave
Cardiovascular adverse conditions are caused by coronavirus disease 2019 (COVID-19) infections and reported as side-effects of the COVID-19 vaccines. Enriching current vaccine safety surveillance systems with additional data sources may improve the understanding of COVID-19 vaccine safety. Using a unique dataset from Israel National Emergency Medical Services (EMS) from 2019 to 2021, the study aims… Continue reading Increased emergency cardiovascular events among under-40 population in Israel during vaccine rollout and third COVID-19 wave
Rates of COVID-19 Among Unvaccinated Adults With Prior COVID-19
Risk of SARS-CoV-2 reinfection among unvaccinated people with prior COVID-19 is a subject of debate.1,2 We performed a survival analysis in a large US population to assess the degree and duration of protection associated with natural immunity in unvaccinated individuals MethodsThis cohort study used data from patients tested for SARS-CoV-2 at 1300 sites of care… Continue reading Rates of COVID-19 Among Unvaccinated Adults With Prior COVID-19
SARS-CoV-2 vaccination can elicit a CD8 T-cell dominant hepatitis
Background & AimsAutoimmune hepatitis episodes have been described following SARS-CoV-2 infection and vaccination but their pathophysiology remains unclear. Here, we report the case of a 52-year-old male, presenting with bimodal episodes of acute hepatitis, each occurring 2-3 weeks after BNT162b2 mRNA vaccination and sought to identify the underlying immune correlates. The patient received first oral… Continue reading SARS-CoV-2 vaccination can elicit a CD8 T-cell dominant hepatitis
SARS-CoV-2 Naturally Acquired Immunity vs. Vaccine-induced Immunity, Reinfections versus Breakthrough Infections: a Retrospective Cohort Study
Background: Waning of protection against infection with SARS-CoV-2 conferred by 2 doses of the BNT162b2 vaccine begins shortly after inoculation and becomes substantial within four months. With that, the impact of prior infection on incident SARS-CoV-2 reinfection is unclear. Therefore, we examined the long-term protection of naturally acquired immunity (protection conferred by previous infection) compared… Continue reading SARS-CoV-2 Naturally Acquired Immunity vs. Vaccine-induced Immunity, Reinfections versus Breakthrough Infections: a Retrospective Cohort Study
Immune-mediated hepatitis with the Moderna vaccine, no longer a coincidence but confirmed
... DiscussionThis case illustrates immune-mediated hepatitis secondary to the Moderna vaccine, which on inadvertent re-exposure led to worsening liver injury with deranged synthetic function. This occurred in a well man with no other medical problems. The onset of jaundice associated with the mRNA vaccine was unusually rapid. This was also illustrated in the other cases… Continue reading Immune-mediated hepatitis with the Moderna vaccine, no longer a coincidence but confirmed
COVID-19 Early Treatment with Non-Steroidal AntiInflammatory Drugs Reduces Hospitalizations andSymptom Duration
BackgroundAt the beginning of the SARS-CoV-2 pandemic we stated that,given the new virus and the little-known disease it caused, in theabsence of Evidence-Based Medicine indications, patients shouldhave been treated with drugs already available, useful to counteractthe pathophysiology of the COVID-19 [1]. Recent literature hasconfirmed that this could be a successful approach, demonstratingthat an early treatment… Continue reading COVID-19 Early Treatment with Non-Steroidal AntiInflammatory Drugs Reduces Hospitalizations andSymptom Duration
Auto-immune hepatitis following COVID vaccination
Unprecedented loss of life due to the COVID pandemic has necessitated the development of several vaccines in record time. Most of these vaccines have received approval without being extensively whetted for their adverse effect and efficacy profiles. Most adverse effects have been mild, nonetheless, more serious thromboembolic events have also been reported. Autoimmune hepatitis (AIH)… Continue reading Auto-immune hepatitis following COVID vaccination
