A new report shows that women aged 12-29 who received AstraZeneca/Oxford University’s Vaxzevria adenovirus vectored COVID-19 vaccine are three and a half times more likely to develop heart disease, suffer sudden death, or both, in the 12 days post vaccination.1
The statistical model linked 11 out of 15 cardiac deaths directly to Vaxzevria, also citing that a positive COVID test was associated with increased cardiac and all-cause mortality. The subgroup who received Vaxzevria was considered to be clinically vulnerable, or high risk, making them more prone to potential adverse reactions, according to the report.
The new findings from the Office for National Statistics in England come two years after that country banned the use of Vaxzevria for people under age 30 due to an increased risk of serious blood clots. AstraZeneca’s COVID vaccine was never granted regulatory approval in the United States.
However, 130 countries received more than 400 million doses of Vaxzevria worldwide. The U.S. Food and Drug Administration (FDA) did authorize a similar non-messenger RNA (mRNA) vaccine, Ad26.COV2.S, manufactured by Johnson & Johnson/Janssen but abruptly called for a pause following reports of rare blood clotting disorders in some recipients.2 3 4
Celebrity Cardiac Events Continue to Draw Adverse Reaction Speculation
Young celebrities and athletes who collapse or die suddenly continue to draw speculation from the public, especially as more evidence emerges that there is a link between mRNA and non-mRNA COVID shots to cardiac events for both sexes. For example, 24-year-old Buffalo Bills football player Damar Hamlin was rushed off of the field after suffering cardiac arrest in January 2023 and immediately there was concern expressed on social media that his heart attack may have been connected with a COVID shot.5
Also in January, Twitter CEO and entrepreneur Elon Musk reported he had suffered a severe reaction to an mRNA COVID booster shot that made him feel like he “was dying” and his cousin, who Musk said was in “peak health,” developed myocarditis (heart inflammation) after a COVID shot and was hospitalized.6
Reproductive Changes Precede New Cardiac Risks in Women
Whether opting for an mRNA COVID shot or non-mRNA COVID shot, an increased risk of heart disease or sudden death two weeks following vaccination are only two risks young women face. Women have reported severe side effects post-COVID vaccinations, with researchers from the U.S. Centers for Disease Control and Prevention (CDC) finding that more women experienced anaphylaxis, a potentially fatal allergic reaction, than males.7
There are continuing reports of menstrual changes that occur after both SARS-CoV-2 infection and after COVID vaccinations.8 There are reports that maternal, fetal and neonatal outcomes worsened during the COVID pandemic.9
In addition, birth rates declined in the U.S. and across the globe during the pandemic.10 However, vaccine researchers and public health officials maintain that there is no evidence COVID shots have any negative impact on fertility.11
While initial reports of menstrual changes were written off by public health officials and physicians administering COVID vaccines as anecdotal or conspiratorial, a global study eventually confirmed a link between vaccination and irregular menstrual cycles.12 13 14 15
Florida Surgeon General Warns Against COVID Vaccination For Males
Men appear to be at higher risk for heart-related risks post-COVID vaccinations. Officials at the CDC acknowledged last year that adolescent and young adult males are more susceptible inflammation of the heart (myocarditis and pericarditis) in the days following Pfizer/BioNTech or Moderna/NIAID mRNA COVID shots. One 2022 study published in the journal Clinical Infectious Diseases found that myocarditis was diagnosed primarily in adult males within the first two weeks following vaccination.16 17
In October 2022, Florida Surgeon General Joseph Ladapo, MD reported state health officials conducting a COVID vaccine safety analysis and found an 84 percent increase in the relative incidence of cardiac-related death among males 18-39 years old within 28 days following mRNA COVID shots administered in the state. As such, Dr. Ladapo advised that males aged 18-39 should not get the COVID shots.18
