Effects of Vaccination and Previous Infection on Omicron Infections in Children
Dan-Yu Lin et al. On October 29, 2021, the Food and Drug Administration authorized the BNT162b2 vaccine (Pfizer–BioNTech) for emergency use in children 5 to 11 years of age, on the basis of an immunobridging study and a small efficacy study.1 Recent case–control studies have shown modest short-term effectiveness of the BNT162b2 vaccine in this […]
China Approves World-first Inhaled COVID-19 Vaccine
Ben Turner China has approved the world’s first inhaled COVID-19 vaccine, the vaccine maker CanSino Biologics (CanSinBIO) in Tianjin, China has announced. The newly approved vaccine, named Convidecia Air, uses the same platform as the injectable COVID-19 vaccine by the same manufacturer — pieces of genetic material transported by a harmless adenovirus vector so the […]
Self-Selected COVID-19 “Unvaccinated” Cohort Reports Favorable Health Outcomes and Unjustified Discimination in Global Survey
Robert Verkerk, Christof Plothe, Naseeba Kathrada and Latarina Lindley Self-reported data collected independently by the UK-based Control Group Cooperative between September 2021 and February 2022, inclusive, from a self-selected international COVID-19 “unvaccinated” population are discussed. Data come from a cohort of 18,497 participants who provided questionnaire responses monthly. The largest numbers are from Europe, North […]
COVID-19 Vaccine Efficacy and Effectiveness – the Elephant (Not) in the Room
Piero Olliaro, Els Torreele, Michel Vaillant Vaccine efficacy is generally reported as a relative risk reduction (RRR). It uses the relative risk (RR)—ie, the ratio of attack rates with and without a vaccine—which is expressed as 1–RR… Although the RRR considers only participants who could benefit from the vaccine, the absolute risk reduction (ARR), which […]
Are Covid Vaccines the Superspread Vector for Omicron?
el gato malo i’ve spoken quite a lot about why leaky vaccines drive viral evolution to select for vaccine advantage. rolling out non-sterilizing vaccines is is terrible idea. it’s like only taking half your course of antibiotics and then wondering why MRSA is suddenly everywhere. it’s just a selector for resistance and advantage. the basic […]
FDA Panel Votes to Waive Clinical Trials for New COVID Boosters
Megan Redshaw The U.S. Food and Drug Administration’s (FDA) vaccine advisory panel on Tuesday voted 19 to 2 to recommend new COVID-19 booster shots that include the Omicron variant this fall. The FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) did not issue guidance on whether additional data would be needed to recommend an updated composition of the primary-series vaccines authorized for […]
Covid & Vitamin D: Lack of Benefit of Vaccines in Canada
David Grimes We can see that in data corrected for prevalence of vaccination, the Covid-19 deaths are higher in the unvaccinated group compared to the three vaccinated groups. There appears to be mortality benefit from one or two vaccinations, but the benefit is lost in those with three vaccinations. My understanding of this is that each […]
Comparing SARS-CoV-2 Natural Immunity to Vaccine-induced Immunity: Reinfections verses Breakthrough Infections
Sivan Gazit et al. Reports of waning vaccine-induced immunity against COVID-19 have begun to surface. With that, the comparable long-term protection conferred by previous infection with SARS-CoV-2 remains unclear. … This study demonstrated that natural immunity confers longer lasting and stronger protection against infection, symptomatic disease and hospitalization caused by the Delta variant of SARS-CoV-2, […]
