High COVID-19 vaccination rates were expected to reduce transmission of SARS-CoV-2 in populations by reducing the number of possible sources for transmission and thereby to reduce the burden of COVID-19 disease. Recent data, however, indicate that the epidemiological relevance of COVID-19 vaccinated individuals is increasing. In the UK it was described that secondary attack rates… Continue reading The epidemiological relevance of the COVID-19-vaccinated population is increasing

Elapsed time since BNT162b2 vaccine and risk of SARS-CoV-2 infection: test negative design study
To determine whether time elapsed since the second injection of the Pfizer-BioNTech BNT162b2 mRNA vaccine was significantly associated with the risk of covid-19 infection after vaccination in people who received two vaccine injections. Design Test negative design study. Setting Electronic health records of a large state mandated healthcare organisation, Israel. Participants Adults aged ≥18 years… Continue reading Elapsed time since BNT162b2 vaccine and risk of SARS-CoV-2 infection: test negative design study
Thyroid as a target of adjuvant autoimmunity/inflammatory syndrome due to mRNA-based SARS-CoV2 vaccination: from Graves’ disease to silent thyroiditis
BackgroundAs COVID-19 became a pandemic, the urgent need to find an effective treatment vaccine has been a major objective. Vaccines contain adjuvants which are not exempt from adverse effects and can trigger the autoimmune/inflammatory syndrome induced by adjuvants (ASIA). There is very little information about autoimmune endocrine disease and the ASIA after the use of… Continue reading Thyroid as a target of adjuvant autoimmunity/inflammatory syndrome due to mRNA-based SARS-CoV2 vaccination: from Graves’ disease to silent thyroiditis
Community transmission and viral load kinetics of the SARS-CoV-2 delta (B.1.617.2) variant in vaccinated and unvaccinated individuals in the UK: a prospective, longitudinal, cohort study
The SARS-CoV-2 delta (B.1.617.2) variant is highly transmissible and spreading globally, including in populations with high vaccination rates. We aimed to investigate transmission and viral load kinetics in vaccinated and unvaccinated individuals with mild delta variant infection in the community. MethodsBetween Sept 13, 2020, and Sept 15, 2021, 602 community contacts (identified via the UK… Continue reading Community transmission and viral load kinetics of the SARS-CoV-2 delta (B.1.617.2) variant in vaccinated and unvaccinated individuals in the UK: a prospective, longitudinal, cohort study
Immune mediated events timely associated with COVID-19 vaccine. A comment on article by Badier, et al.: “IgA vasculitis in adult patients following vaccination by ChadOx1 nCoV-19”
Dear Editor,We read the article by Badier et al. entitled “IgA vasculitis in adult patients following vaccination by ChadOx1 nCoV-19”, published in Autoimmunity Reviews with interest. (1) We share the author's view that the COVID-19 vaccine could be the trigger of IgA vasculitis in the reported case. At our secondary/tertiary rheumatology centre, we have been… Continue reading Immune mediated events timely associated with COVID-19 vaccine.

Discovery of a novel pseudo β-hairpin structure of N-truncated amyloid-β for use as a vaccine against Alzheimer’s disease
One of the hallmarks of Alzheimer’s disease (AD) are deposits of amyloid-beta (Aβ) protein in amyloid plaques in the brain. The Aβ peptide exists in several forms, including full-length Aβ1-42 and Aβ1-40 – and the N-truncated species, pyroglutamate Aβ3-42 and Aβ4-42, which appear to play a major role in neurodegeneration. We previously identified a murine… Continue reading Discovery of a novel pseudo β-hairpin structure of N-truncated amyloid-β for use as a vaccine against Alzheimer’s disease
Transmission of SARS-CoV-2 Delta Variant Among Vaccinated Healthcare Workers, Vietnam
Background: Data on breakthrough SARS-CoV-2 Delta variant infections are limited. Methods: We studied breakthrough infections among healthcare workers of a major infectious diseases hospital in Vietnam. We collected demographics, vaccination history and results of PCR diagnosis alongside clinical data. We measured SARS-CoV-2 (neutralizing) antibodies at diagnosis, and at week 1, 2 and 3 after diagnosis.… Continue reading Transmission of SARS-CoV-2 Delta Variant Among Vaccinated Healthcare Workers, Vietnam
Transparency of COVID-19 vaccine trials: decisions without data
Summary boxData transparency has become a well-established norm in biomedical research, and is especially important for broadly used public health interventions like COVID-19 vaccines. Tax payers helped fund COVID-19 vaccine trials and should have the right to access the results. There is inadequate availability of COVID-19 vaccine trial documents and data; individual participant data will… Continue reading Transparency of COVID-19 vaccine trials: decisions without data
A novel adverse effect of the BNT162b2 mRNA vaccine: First episode of acute #mania with #psychotic features
Dear Editor;A vaccine against SARS-CoV2, which is causing the global COVID-19 pandemic, was developed for the first-time using mRNA technology. Although the short- and long-term side-effects of the vaccine were unknown, emergency use authorization (EUA) was granted by the Food and Drug Administration (FDA) in December 2020(Parkash et al., 2021). Adverse effects such as tiredness,… Continue reading A novel adverse effect of the BNT162b2 mRNA vaccine: First episode of acute #mania with #psychotic features
