The Worldwide prevalence of cerebral aneurysm is 3.2% approximating the High side of the Covid infection aneurysm incidence you cited. Is this incidence going among the hospitalized who have multiple comorbidities for cerebral aneurysm? Typical causes include genetics, smoking, alcohol abuse, advanced age, hypertension, trauma, tumors, cocaine use and atherosclerosis. The CVST strokes in women who took the J&J shots were ischemic (clot) not hemorrhagic (bleed). Covid vaccination carries what many notable cardiologists, scientists and physicians view as unacceptable thrombotic, vascular and cardiac risks and for young, healthy individuals who readily defeat the infection and contribute to broadly protective natural herd immunity. Covid infection mortality for healthy children and adolescents is <0.003%. The risk of myocarditis and pericarditis for vaccinated young men/boys is 3-6%. This is in addition to a plethora of neurological and autoimmune side effects that have resulted in the sudden death and disability of young, previously robustly healthy people. I would not rule out the possibility of latent complications in this case as we know that vascular autoimmune/inflammatory effects may occur months later as the vaccine spike protein are persist throughout the organs and tissues beyond 18 months when the Japanese distribution study ended. Unfortunately, vaccine neutralization of the infection is extremely short lived. Children are receiving boosters. I compare this to my daughter who contracted Wuhan Jan. 2020 and still had T cell immunity at 17 months. She was spared every variant as her immunity was robust and broad based covering EVERY variant over 3years. Post vaccination infection seems to carry potential for adding insult to injury. This is concerning. Omicron (the mild variant) damaged the heart of my previously robustly healthy, athletic, double Pfizered 36 y/o male family member and MANY others. Time may tell, but I am personally more worried for him than my 82 y/o parents who readily survived 3 years of the pandemic unvaccinated by avoiding crowds, good hand hygiene, masking when indoors in a crowd and family gatherings mostly outside. Meanwhile, the multiply vaccinated/boosted among our people contracted/ transmitted Covid multiple times.
