So we are talking about something quite subtle here and that is currently under investigation. At this stage I would say wait and see, don't panic. it is not something absolutely disastrous like we saw previouslyDr Jeffrey Barrett, Covid-19 Genomics Initiative, Wellcome Sanger Institute, Cambridge, and Prof Francois BallouxAY.4.2 could be 10-15% more transmissible than the original Delta variant.Unlikely to be fuelling current UK increases(That’s mostly school age and to their parents) Learn more about your ad choices.

Emerging evidence suggests that the biodistribution and persistence of modRNA, facilitated by lipid nanoparticles, can affect various tissues and organs, including the bone marrow and other blood-forming organs. Unfettered access through most tissues and organs, Notably, modRNA vaccines exhibit a particular affinity for the bone marrow, potentially influencing the immune system at multiple levels and, triggering both autoimmune disorders and neoplastic processes. By integrating clinical observations and current research, we aim to provide valuable insights into the potential carcinogenic outcomes associated with modRNA vaccination. Cancer causing Mechanisms Toxic spike protein Vaccine induced lasts for longer than natural spike A double proline that confers greater stability. Synthetic pseudouridines contained in the modRNA have shown mitochondrial toxicity It has been demonstrated that this modification can increase the likelihood of +1 ribosomal frameshifting during translation, resulting in the production of multiple peptide products with unexplored effects (This obviously poses serious safety concerns as only a single antigen was supposed to be encoded by the modRNA, not many undefined peptides with unknown antigenic and autoimmune potential.) LNPs exhibits intrinsic cytotoxicity. Presence of LNP-encapsulated DNA contamination originating from residual plasmid DNA DNA integration may include the risk of tumorigenisis if insertion reduces the activity of a tumour suppressor or increases the activity of an oncogene.

We estimated the risk of COVID-19 deaths (primary outcome)We estimated the risk of SARS-CoV-2 infections (secondary outcome)MethodsAustria nationwide retrospective observational study. 1 November to 31 December 2022Primarily comparing individuals with four versus three vaccine doses. Whole population data.Results3,986,312 previously infected individuals281,291 (7,1%) had four vaccinations at baseline1,545,242 (38.8%) had three vaccinations at baseline We recorded69 COVID-19 deaths89,056 SARS-CoV-2 infectionsThe majority of COVID-19 deaths and a significant proportion of all-cause deaths occurred in nursing home residentsRelative vaccine effectiveness (rVE) for four versus three vaccine doses-24% against COVID-19 deaths17% against SARS-CoV-2 infections. Protection against infection rapidly diminished over time,and infection risk with four vaccinations was higher during extended follow-up until June 2023. Adjusted HR for all-cause mortality for four versus three vaccinations was 0.79.That is people with a 4th dose were only 79% as likely to die(Suggesting healthy vaccinee bias, i.e. healthier persons received more vaccine doses)DiscussionIn previously infected individuals, a fourth vaccination did not reduce COVID-19 death risk, but with transiently reduced risk of SARS-CoV-2 infections,and reversal of this effect in longer follow-up. All-cause mortality data suggest healthy vaccinee bias.More detailsMostly Pfizer vaccine, some ModernaIn this study, overall case fatality rate, 0.08%.(IFR, ? 0.008% if 10% of infections picked up)Individuals with repeated previous infections had reduced re-infection riskNatural immunity may be a main determinant of immunological protection in a populationBy end 2022, the vast majority of the global population had already acquired some immune protectionCompared to three vaccine doses, those with fewer or no vaccinations did not differ with regard to COVID-19 mortality,but had reduced risk of SARS-CoV-2 infections.In 2022, infection fatality rates due to SARS-CoV-2 significantly declined suggesting transitioning into endemicity.In general, our study results question whether recommendations for repeated vaccine boosters against SARS-CoV-2 are currently justified for large parts of the general population with a history of previous infections. Measures against SARS-CoV-2 including vaccine policy should be critically re-assessed for their risk-to-benefit ratio.As most SARS-CoV-2 infections are asymptomatic or mild in an endemic phase, effectiveness of vaccinations should be primarily evaluated according to hard clinical outcomes (e.g. COVID-19 deaths)Extended follow-upFrom 1 January to 30 June 2023Omicron XBB.1.5. was the predominant variant225 COVID-19 deaths174,174 SARS-CoV-2 infections.

Paper Authors Beijing Advanced Innovation Center Beijing University of Chemical Technology, The Fifth Medical Center of PLA General Hospital, Beijing, China. Medical School, Nanjing University, China (including a doctor trained by the Chinese military, Yigang Tong) Purpose of study Assessed virus pathogenicity Risk 100% IFR underscores a spillover risk of GX_P2V into humans, and provides a unique model for understanding the pathogenic mechanisms of SARS-CoV-2-related viruses. Details GX_P2V isolate was actually a cell culture-adapted mutant In this study, we cloned this mutant This is not a wild type virus It is possible that GX_P2V C7 has undergone a virulence-enhancing mutation. GX_P2V is capable of rapid mutation rates. High viral loads detected in both lung and brain tissues. Surprisingly, all the mice that were infected with the live virus succumbed to the infection within 7-8 days post-inoculation, Resulted in 100% mortality in the hACE2 mice. Clinical features Weight loss, Piloerection, hunched posture, sluggish movements, and their eyes turned white.

Coronavirus research in China is often done at a biosafety level (BSL-2) that is inadequate for working with potential pandemic pathogens that might be transmitted by air. “Indeed, coronavirus research done at BSL-2 may have caused the COVID-19 pandemic. And by showing that the coronavirus has a surprisingly high pathogenicity, the work underscores the need for extreme caution when working with novel coronaviruses.” Justin Goodman, senior vice president of the White Coat Waste Project, a U.S. nonprofit China-based scientists have been conducting “dangerous and deadly tests on mice.” “This is why shipping U.S. tax dollars to foreign adversaries’ unaccountable animal labs is a recipe for disaster …… Learn more about your ad choices.

    Moderna Receives U.S. FDA Approval for RSV Vaccine mRESVIA(R) https://news.modernatx.com/news/news-details/2024/Moderna-Receives-U.S.-FDA-Approval-for-RSV-Vaccine-mRESVIAR/default.aspx May 31, 2024 Moderna, today announced that the U.S. Food and Drug Administration (FDA) has approved mRESVIA (mRNA-1345), an mRNA respiratory syncytial virus (RSV) vaccine, to protect adults aged 60 years and older from lower respiratory tract disease caused by RSV infection. The approval was granted under a breakthrough therapy designation and marks the second approved mRNA product from Moderna. Stéphane Bancel, Chief Executive Officer of Moderna. The FDA approval of our second product, mRESVIA, builds on the strength and versatility of our mRNA platform Moderna expects to have mRESVIA available for eligible populations in the U.S. by the 2024/2025 respiratory virus season. Moderna has filed for mRNA-1345 approval with regulators in multiple markets around the world. https://www.clinicaltrialsarena.com/news/moderna-races-ahead-in-flu-and-covid-19-combo-vaccine-race-with-phase-iii-win/ Moderna races ahead in flu and Covid-19 combo vaccine race with Phase III win Moderna injection mRNA-1083 Comprises a seasonal influenza vaccine candidate, mRNA-1010, and a next-generation Covid-19 vaccine prospect called mRNA-1283. Moderna announces positive data from a Phase III trial of its mRNA vaccine candidate. Now, in a Phase III trial (NCT06097273) for mRNA-1083 Moderna “statistically significantly higher immune responses” compared to existing vaccines on the market. The trial met its primary endpoints, Moderna said in a 10 June press release. Immune response was seen across three influenza virus strains (H1N1, H3N2, and B/Victoria) and against SARS-CoV-2. Although Moderna has not published the full dataset from the Phase III trial, it plans to present the results in more detail at an upcoming medical conference, in addition to a submission for publication. The company said it “will engage with regulators on next steps”.
