Policy makers and mainstream news anchors have promised the public that the COVID-19 vaccine rollout worldwide would reduce symptoms, and thereby cases and deaths associated with COVID-19. While this vaccine rollout is still in progress, there is a large amount of public data available that permits an analysis of the effect of the vaccine rollout… Continue reading Worldwide Bayesian Causal Impact Analysis of Vaccine Administration on Deaths and Cases Associated with COVID-19: A BigData Analysis of 145 Countries

Thyroiditis after Coronavirus Disease 2019 (COVID-19) mRNA Vaccine: A Case Series
Highlights1)Thyrotoxicosis with palpitation, and neck tenderness is the most common presentation of thyroiditis. The patients with new onset of thyrotoxicosis should be asked about history of mRNA-vaccine injection for the possible etiology. 2)mRNA vaccine induced thyroiditis could occur 10-20 days after the first dose or the second dose. 3)Management is to relieve the symptom of… Continue reading Thyroiditis after Coronavirus Disease 2019 (COVID-19) mRNA Vaccine: A Case Series
Vaccine effectiveness against SARS-CoV-2 infection with the Omicron or Delta variants following a two-dose or booster BNT162b2 or mRNA-1273 vaccination series: A Danish cohort study
In this brief communication we are showing original research results with early estimates from Danish nationwide databases of vaccine effectiveness (VE) against the novel SARS-CoV-2 Omicron variant (B.1.1.529) up to five months after a primary vaccination series with the BNT162b2 or mRNA-1273 vaccines. Our study provides evidence of protection against infection with the Omicron variant… Continue reading Vaccine effectiveness against SARS-CoV-2 infection with the Omicron or Delta variants following a two-dose or booster BNT162b2 or mRNA-1273 vaccination series: A Danish cohort study
SARS-CoV-2 Omicron VOC Transmission in Danish Households
The Omicron variant of concern (VOC) is a rapidly spreading variant of SARS-CoV-2 that is likely to overtake the previously dominant Delta VOC in many countries by the end of 2021. We estimated the transmission dynamics following the spread of Omicron VOC within Danish households during December 2021. We used data from Danish registers to… Continue reading SARS-CoV-2 Omicron VOC Transmission in Danish Households
Evaluating the number of unvaccinated people needed to exclude to prevent SARS-CoV-2 transmissions
Vaccine mandates and vaccine passports (VMVP) for SARS-CoV-2 are thought to be a path out of the pandemic by increasing vaccination through coercion and excluding unvaccinated people from different settings because they are viewed as being at significant risk of transmitting SARS-CoV-2. While variants and waning efficacy are relevant, SARS-CoV-2 vaccines reduce the risk of… Continue reading Evaluating the number of unvaccinated people needed to exclude to prevent SARS-CoV-2 transmissions
Post-SARS-CoV-2 vaccination venous sinus thrombosis: a literature review of 308 cases
There is accumulating evidence that SARS-CoV-2 vaccinations can be complicated by venous sinus thrombosis (VST). This review aimed at summarising and discussing previous and recent advances regarding the diagnosis, pathogenesis, treatment, and outcome of post-SARS-CoV-2 vaccination VST. At least 308 patients with post-SARS-CoV-2 vaccination VST have been reported as per the end of July 2021.… Continue reading Post-SARS-CoV-2 vaccination venous sinus thrombosis: a literature review of 308 cases
Mucosal immune response in BNT162b2 COVID-19 vaccine recipients
Although the BNT162b2 COVID-19 vaccine is known to induce IgG neutralizing antibodies in serum protecting against COVID-19, it has not been studied in detail whether it could generate specific immunity at mucosal sites, which represent the primary route of entry of SARS-CoV-2. MethodsSamples of serum and saliva of 60 BNT162b2-vaccinated healthcare workers were collected at… Continue reading Mucosal immune response in BNT162b2 COVID-19 vaccine recipients
COVID-19 Vaccination and Breakthrough Infections in Patients with Cancer
Highlights•Patients with cancer who develop breakthrough COVID-19 following full vaccination remain susceptible to severe outcomes.•Hematologic malignancies are over-represented among vaccinated patients with cancer who develop breakthrough COVID-19.•Vaccination of close contacts, masking, boosters, and social distancing are needed to protect patients with cancer. AbstractBackgroundVaccination is an important preventive health measure to protect against symptomatic and severe… Continue reading COVID-19 Vaccination and Breakthrough Infections in Patients with Cancer
Striking Antibody Evasion Manifested by the Omicron Variant of SARS-CoV-2
The Omicron (B.1.1.529) variant of SARS-CoV-2 was only recently detected in southern Africa, but its subsequent spread has been extensive, both regionally and globally. It is expected to become dominant in the coming weeks, probably due to enhanced transmissibility. A striking feature of this variant is the large number of spike mutations that pose a… Continue reading Striking Antibody Evasion Manifested by the Omicron Variant of SARS-CoV-2
