Spreadsheet analysis of the Paul Ehrlich data for 2020 to 2023 shows a high incidence of cardiac symptoms for Covid vaccines . Tachycardia and arrhythmia occur with an incidence of
>1 / 100 and therefore rank as "Common" events. Disorders of the menstrual/ovulatory cycle also occur with a high incidence (just less than 1 / 100).The Paul Ehrlich institute did a study of all other vaccines, excluding Covid vaccines, and identified the top 20 adverse effects. Non-Covid Vaccine Study by PEI. Cardiac and menstrual adverse events were absent in their top 20. These findings indicate that a proportional reporting ratio study should be carried out, comparing Covid and non-Covid vaccines.
