AstraZeneca admits to rare, deadly side effect of Covid jab as lawsuits mount

I had two shots of AstraZeneca and didn't even get a sore arm out of it -- nothing. So your mileage may vary

AstraZeneca has admitted that its Covid-19 vaccine could cause a rare but deadly blood-clotting condition, potentially exposing the UK pharmaceutical giant to lawsuits brought by loved ones of those injured or killed as a result of the jab, according to court documents.

Lawyers representing “dozens” of class-action claimants say some of their clients’ cases could be worth as much as $38 million, calling the Cambridge-headquartered pharma firm’s vaccine was “defective,” according to the Daily Mail.

Recent research from RMIT University and Monash University found Australia’s Covid-19 vaccination campaign likely prevented the death of 17,760 people aged over 50 in New South Wales between August 2021 and July 2022.

The AstraZeneca inoculation, which was also administered in Australia, has proven to be effective in combating Covid-19 with some estimates suggested it saved as many as six million lives worldwide. But it has also produced rare side effects in some people, reports the New York Post.

AstraZeneca, which is contesting the claims, acknowledged in a February legal document that its vaccine can “in very rare cases,” cause a condition called thrombosis with thrombocytopenia syndrome, or TTS.

TTS can cause patients to suffer from blood clots as well as a low blood platelet count, which in some cases have seriously harmed or even killed recipients of the company’s vaccine.

The potential complication was listed as a possible side effect from the time of the vaccine’s release, but AstraZeneca’s acknowledgment in February marks the first time the pharmaceutical titan has admitted it in court, according to the UK newspaper The Telegraph.

So far, 51 cases have been filed in London’s High Court, estimated to be worth around $190 million (GBP100 million) total, the outlet writes.

Due to a bargain AstraZeneca struck with the UK government at the height of the pandemic to indemnify the drugmaker against potential lawsuits, taxpayers will be on the hook for any payouts resulting from the claims.

One of the claimants who filed suit is Jamie Scott, an IT engineer and father of two left with a permanent brain injury resulting from a blood clot after he received the vaccine in April 2021.

His wife, Kate, told The Telegraph she’s hopeful the company’s admission will accelerate the outcome of their case.

“We need an apology, fair compensation for our family and other families who have been affected. We have the truth on our side, and we are not going to give up.”

In a statement, AstraZeneca expressed sympathy for anyone who was allegedly harmed by the vaccine, but defended it as a net positive and pointed out that complications are exceedingly rare.

“Patient safety is our highest priority, and regulatory authorities have clear and stringent standards to ensure the safe use of all medicines, including vaccines,” the statement reads in part.

“From the body of evidence in clinical trials and real-world data, the AstraZeneca-Oxford vaccine has continuously been shown to have an acceptable safety profile and regulators around the world consistently state that the benefits of vaccination outweigh the risks of extremely rare potential side effects.”

The AstraZeneca Covid vaccine was first approved for emergency use in December, 2020.

Of the 50 million doses administered in the UK during the crisis, 81 people have died from blood clots potentially linked to the jab, according to health data compiled by UK pharmaceutical watchdog the Medicines and Healthcare Products Regulatory Agency.

The odds of a recipient developing TTS as a result of the vaccine is calculated as somewhere in the range of 1 in 50,000.

In Australia, the government said the rate of TTS linked to the jab was around two people per 100,000 vaccinated.

In all, the AstraZeneca vaccine is credited with saving as many as six million lives globally during the pandemic, according to the University of Oxford, which partnered with the company in developing the jab.

Small Chinese sample suggests link between Pfizer-BioNTech mRNA COVID-19 Vaccine and Kidney-Related Disease

A team of nephrologists and associated physician-scientists from Zhengzhou University in Zhengzhou, a city with over 10 million people in Northern China extracted the gene expression data of Peripheral Blood Mononuclear Cells (PBMCs) from 15 controls (day 0 post the second dose of Pfizer-BioNTech BNT162b2 COVID-19 mRNA vaccine) and 29 vaccinated samples (day 1–10 post second dose also of the same BNT162b2 COVID-19 mRNA vaccine) (GSE201535) from what is known as the Gene Expression Omnibus (GEO) dataset and normalization of the counts by log(x + 1) using Sangerbox.

Meanwhile, the gene expression data of glomeruli from 21 controls (living donors) and 27 IgAN were collected (GSE104948). Also in this study, focusing on the keyword “COVID-19 vaccine” was used to search the GeneCards database to screen the associated genes supporting this investigation into cases of glomerulonephritis, a kidney condition reported after the mass-scale use of COVID-19 countermeasures with IgA nephropathy (IgAN) emerging as particularly prominent.

The recent study results were published in Karger Kidney and Blood Pressure Research, and the study was conducted with the help of Henan Provincial People’s Hospital.

What is IgAN and glomerulonephritis?

Glomerulonephritis is a group of kidney diseases that cause inflammation of the glomeruli, the tiny filters inside the kidneys that remove waste and extra fluids from the blood, this condition can come on quickly or slowly, and mild cases often don’t cause any noticeable symptoms.

IgAN or IgA nephropathy is considered a rare kidney disease occurring when the body’s immune system generates antibodies in the kidneys, leading to inflammation and kidney damage. The inflammation makes it harder for the kidneys to filter waste and fluid from the blood. IgAN is also known as Berger disease.

Background to this study

The Chinese researchers point to “accumulating evidence” disclosing the risk of IgA nephropathy (IgAN) presenting shortly after the second dose of the COVID-19 mRNA vaccine. But not surprisingly, the undying mechanism remains unclear. Thus, the investigation here better understands potential molecular mechanisms.

The team downloaded both gene expression datasets of COVID-19 mRNA vaccination (GSE201535) and IgAN (GSE104948). Weighted Gene Co-Expression Network Analysis (WGCNA) in a bid to identify co-expression modules related to the second dose of COVID-19 mRNA vaccination and IgAN. Differentially expressed genes (DEGs) were screened, and a transcription factor (TF)-miRNA regulatory network and protein-drug interaction were constructed for the shared genes.

What did they find?

The use of WBCNA led to the identification of one module linked to the second dose of the Pfizer-BioNTech mRNA vaccine, with four modules linked to IgAN. Further analysis employing gene ontology (GO) uncovered “enrichment of cell cycle-related processes for the COVID-19 mRNA vaccine hub genes and immune effector processes for the IgAN hub genes.”

With 74 DEGs identified in relation to the second Pfizer dose, plus 574 DEGs for IgAN, “Intersection analysis with COVID-19 vaccine-related genes led to the identification of two shared genes, TOP2A and CEP55. The TF-miRNA network analysis showed that hsa-miR-144 and ATF1 might regulate the shared hub genes.”

Summary

The team shares in this paper a “common pathogenesis of COVID-19 mRNA vaccination and IgAN. The identified pivotal genes may offer new directions for further mechanistic studies of IgAN secondary to COVID-19 mRNA vaccination.”
