Senator Asks CDC to Clear Up Conflicting Statements on Vaccine Safety Research

A U.S. senator is asking the Centers for Disease Control and Prevention (CDC) to clear up conflicting statements on whether a specific method of COVID-19 vaccine safety research is being conducted.

Sen. Ron Johnson (R-Wis.) asked CDC Director Rochelle Walensky for details after The Epoch Times reported that Dr. John Su, a CDC doctor, claimed that the CDC has been performing Proportional Reporting Ratio analyses on data from the Vaccine Adverse Event Reporting System since February 2021.

That conflicted with the CDC telling the nonprofit Children’s Health Defense that it not only did not conduct the analyses but that the method “is outside of th[e] agency’s purview.”

“CDC’s assertion and Dr. Su’s statement cannot both be true,” Johnson told Walensky in a new letter, released on July 26 and dated July 25.

“The American people deserve the truth and you have not been providing it. That is why I, together with millions of Americans, have completely lost faith in the CDC and other federal health agencies. It is time to start regaining their confidence and your agency’s integrity by coming clean, being transparent, and telling the truth,” Johnson wrote.

He asked for Walensky to immediately respond to a letter he sent before requesting information on the CDC’s vaccine safety research. He also requested she confirm whether Dr. Su’s statement is true and if it is, why the CDC claimed it had not conducted the analyses.

And if Dr. Su’s statement is accurate, Johnson wants all of the Proportional Reporting Ratio analyses that the CDC has performed since February 2021.

Finally, Johnson asked for Dr. Su to be made available for an interview with his office concerning the data examinations.

The CDC and Walensky did not immediately respond to requests for comment.

Background

The CDC said in an operating procedures document dated Jan. 29, 2021, that it “will perform” Proportional Reporting Ratio (PRR), a type of data mining analysis that compares the counts of adverse event reports following vaccination with one vaccine to those that have been reported after receipt of another vaccine or vaccines.

Sen. Johnson Points Out Conflicting CDC Statements on Surveillance of COVID-19 Vaccine Adverse Events

WASHINGTON – On Monday, U.S. Sen. Ron Johnson sent a follow-up letter to Rochelle Walensky, Director of the Centers for Disease Control and Prevention (CDC), demanding clarity on whether the agency performed sufficient surveillance of COVID-19 vaccine adverse events. Recent conflicting statements by CDC officials about monitoring adverse events called into question CDC’s integrity and transparency.

In a June 2022 letter to the CDC, Sen. Johnson outlined the CDC’s Standard Operating Procedures (SOP) document dated January 29, 2021, in which the agency claimed it would “perform routine [Vaccine Adverse Event Reporting System (VAERS)] surveillance to identify potential new safety concerns for COVID-19 vaccines.”  The SOP also stated that the “CDC will perform Proportional Reporting Ratio (PRR) analysis . . . to identify [adverse events]” and “perform PRR data mining on a weekly basis or as needed.”

However, in response to a May 9, 2022 Freedom of Information Act (FOIA) request, the CDC wrote, “no PRRs were conducted.”

Dr. John Su, a CDC official on the agency’s Vaccine Safety Team, recently said the opposite to a media outlet claiming that the “CDC has been performing PRRs since Feb 2021, and continues to do so to date.”

The senator wrote, “CDC’s assertion and Dr. Su’s statement cannot both be true.”

“The American people deserve the truth and you have not been providing it. That is why I, together with millions of Americans, have completely lost faith in the CDC and other federal health agencies. It is time to start regaining their confidence and your agency’s integrity by coming clean, being transparent, and telling the truth,” the senator added.

July 25, 2022

Rochelle P. Walensky, MD, MPH
Director
Centers for Disease Control and Prevention

Dear Director Walensky: 

On June 23, 2022, I wrote to you about whether the Centers for Disease Control and Prevention (CDC) performed sufficient surveillance of COVID-19 vaccine adverse events (enclosed).[1]  To date, the CDC has failed to provide a response to that letter.

In that letter, I described the CDC and the Food and Drug Administration’s Standard Operating Procedures (SOP) document dated January 29, 2021, which declared that the agencies would “perform routine [Vaccine Adverse Event Reporting System (VAERS)] surveillance to identify potential new safety concerns for COVID-19 vaccines.”[2]  Yet, in response to a Freedom of Information Act (FOIA) request for these surveillance records, CDC failed to provide data it originally claimed it would generate.[3]

As I noted in my letter, the SOP stated that “CDC will perform Proportional Reporting Ratio (PRR) analysis  . . . to identify [adverse events] that are disproportionately reported relative to other [adverse events].”[4]  The SOP also stated that, “CDC will perform PRR data mining on a weekly basis or as needed.”[5]  However, in response to the May 9, 2022 FOIA request for these records, CDC wrote, “no PRRs were conducted” and that “data mining is outside of th [sic] agency’s purview.”[6]

The validity of this assertion has recently been called into question.  Although CDC claimed that “no PRRs were conducted,” Dr. John Su, a CDC official that works on the Vaccine Safety Team, reportedly told a media outlet that “CDC has been performing PRRs since Feb 2021, and continues to do so to date.”[7]  CDC’s assertion and Dr. Su’s statement cannot both be true.

The American people deserve the truth and you have not been providing it. That is why I, together with millions of Americans, have completely lost faith in the CDC and other federal health agencies.  It is time to start regaining their confidence and your agency’s integrity by coming clean, being transparent, and telling the truth.

 Accordingly, please provide an immediate and complete response to my June 23, 2022 letter and the following information by no later than July 29, 2022:

  1. Is Dr. Su’s statement that “CDC has been performing PRRs since Feb 2021, and continues to do so to date” true?[8]
    1. If so, why did CDC claim that “no PRRs were conducted” in response to a May 9, 2022 FOIA request?[9]
    2. If Dr. Su’s statement is true, please provide all of the PRRs performed since February 2021.
  2. Please make Dr. Su available for an interview with my office to discuss the types of surveillance CDC has performed regarding COVID-19 vaccine adverse events and the data CDC has generated based on its surveillance.

Thank you for your attention to this important matter.

Sincerely,

###
