| Condition | Observed Increase | Vaccine Type |
|---|---|---|
| Myocarditis (heart inflammation) | Up to 2.6× higher after 4th mRNA dose | Pfizer, Moderna |
| Pericarditis (heart lining) | ~1.7× higher after 1st dose | mRNA vaccines |
| Guillain-Barré Syndrome | 190 cases observed vs. 66 expected | AstraZeneca |
| Cerebral venous sinus thrombosis | 3.2× higher after 1st AstraZeneca dose | Viral-vector vaccines |
| Acute disseminated encephalomyelitis | 7 cases vs. 2 expected after mRNA vaccines | Pfizer, Moderna |
| Transient ischemic attack (TIA) | 1.13× higher after 2nd dose, mostly in elderly | mRNA vaccines |
| Extrasystoles (irregular heartbeats) | 1.22× higher after 2nd dose | mRNA vaccines |
These increases are statistically significant, but still rare in absolute terms. For example, acute brain inflammation (ADEM) occurred in 1 case per 1.75 million vaccinated.
🧠 What About Cancer and Stroke?
- Cancer: No peer-reviewed studies have shown a statistically significant increase in cancer rates due to COVID-19 vaccination3
- Stroke: Most studies show no increased risk, and some report reduced stroke incidence after full vaccination2
🏛️ What Agencies Are Doing
- FDA has added warning labels for myocarditis and pericarditis
- CDC continues to monitor adverse events through VAERS and v-safe
- NIH is funding long-term studies on neurological and cardiovascular outcomes
These statistics come directly from published studies—not opinion. If you’d like, I can help you explore the raw datasets or visualize how these risks compare across age groups and vaccine types. Or sketch a cartoon of spike proteins nervously tiptoeing past a cardiologist with a clipboard. 😄

yes, what does the vears show
VAERS—the Vaccine Adverse Event Reporting System—has received over 1.66 million reports related to COVID-19 vaccines in the U.S. through June 27, 2025, according to OpenVAERS, which aggregates publicly available data from the CDC and FDA. Here’s a breakdown of key reported outcomes:
📊 VAERS COVID Vaccine Reports (U.S. & Territories)
| Reported Outcome | Number of Reports |
|---|---|
| Deaths | 38,709 |
| Hospitalizations | 221,030 |
| Urgent Care Visits | 156,774 |
| Doctor Office Visits | 248,071 |
| Anaphylaxis | 10,969 |
| Bell’s Palsy | 17,928 |
| Miscarriages | 5,183 |
| Heart Attacks | 22,331 |
| Myocarditis/Pericarditis | 28,966 |
| Permanently Disabled | 73,691 |
| Life-Threatening Events | 41,176 |
| Severe Allergic Reactions | 47,416 |
| Shingles | 16,397 |
🧠 Important Caveats
- VAERS is a passive reporting system: Anyone can submit a report—patients, doctors, or manufacturers.
- Reports are not verified diagnoses: They may be incomplete, coincidental, or unconfirmed.
- Causality is not established: A report does not mean the vaccine caused the event.
- CDC and FDA use VAERS to detect safety signals, which are then investigated using more rigorous systems like VSD and CISA2.
