Comparing COVID Vaccine with INFLUENZA Vaccine
using Vigiaccess.org database (WHO database)by Craig Paardekooper

COVID 19 vaccine data :Input : COMIRNATYFLU vaccine data

Input : FLU (INFLUENZA);

Signal Detection :On January 29th of 2021 the CDC released a document titled 'Vaccine Adverse Event Reporting
System (VAERS) Standard Operating Procedures for COVID-19' (for official use only) whichannounced the CDC's intention:"CDC will perform Proportional Reporting Ratio (PRR) analysis [...], excluding laboratory results,
to identify AEs that are disproportionately reported relative to other AEs. [...] To determine if
results need further clinical review, consider if clinically important, unexpected findings,
seriousness, specific syndrome or diagnosis rather than non-specific symptoms"(CDC, 2022-0926)
Alas, the CDC never followed up on their promise or at least they did not release their results, so I
am going to use the CDC’s signal detection method here, and see what they should have told us.
PRR calculates the percentage of reports with a particular symptom following administration of drugA, and sees if this varies significantly from the percentage of reports with a particular symptom
following administration of drug B.
The difference is significant if –1. (percentage for drug A)/(percentage for drug B) > 1
2. Number of reports of symptom > 3 for both drugs
3. The lower limit for the 95% confidence interval of the ratio > 1
All these criteria are satisfied in the study that follows.

Computation of PRR Ratio

Discussion
COVID 19 vaccine has high PRR ratio relative to FLU vaccine for symptoms of Reproductive disorder.
The PRR ratio is very large (15.6) indicating that the percentage of COVID-19 vaccine reports involving
disorders of the reproductive system is 15 times larger than the percentage of FLU vaccine reports
involving disorders of the reproductive system.
Similarly the percentage of reports of COVID vaccination with cardiac disorders is 2.6 x thepercentage of reports of FLU vaccination with cardiac disorders.
These results are significant at the 95% Confidence interval, demonstrating that reproduction isimpaired in the COVID vaccinated significantly more than in the FLU vaccinated. Heart injury andcancer rates are also significantly increased.

Deeper Analysis
To understand how reproduction is impaired, we can take a closer look at the symptoms included
under “Reproductive Disorders”
The WHO lists the following reproductive symptom counts for COVID-19 vaccinations

Let us take heavy menstrual bleeding as an example
WHO recorded 69666 cases of heavy menstrual bleeding following COVID 19 vaccination, and 79
cases following FLU vaccination. So the percentage of COVID 19 reports with heavy menstrual
bleeding is 69666/5188403 = 1.34%. In comparison the percentage of FLU reports with heavy
menstrual bleeding is 79/312445 = 0.025%. The PRR ratio 1.34 : 0.025 or 53 : 1. So you can see that
there is a massive difference in reproductive disorder between these two vaccines.
Please note that I have not included all the different counts of menstrual disturbance listed above,
only the first one. If I included all of them, the PRR would be much greater.
