DR. WILLIAM GRUBER, PFIZER'S VP OF VACCINE CLINICAL TRIALS: “Obviously, we don’t have a complete understanding of the nature of the way the vaccine works.”

“A with all vaccines for any population, when authorizing COVID-19 vaccines intended for pediatric age groups, the FDA ensures that our evaluation and analysis of the data is rigorous and thorough.”  Peter Marks, M.D., Ph.D., Director of the FDA’s Center for Biologics Evaluation & Research, June 17, 2022.

0:16  Sonia Elijah interviews Dr. David Wiseman on the FDA’s controversial decision to authorize Moderna & Pfizer-BioNTech’s COVID-19 vaccines for children as young as 6 months old, based on a unanimous vote by VRBPAC, the FDA’s expert advisory committee, during the June 14-15 virtual meeting. 

David Wiseman, thank you so much for talking with me again.

WISEMAN: . . . the FDA, so that the data on the third vaccine dose data is “imprecise, it’s unstable.”  We have no idea what the efficacy is for Pfizer in the third dose.  If you have no idea what the efficacy is, then you cannot begin to calculate a risk-benefit ratio.  FDA believes that the drug “may be effective” and that the benefits outweigh the risks.  If you don’t know what the benefits are, if you don’t know what the efficacy is, how can you calculate what the risk-benefit ratio is?

[Here is the full interview with David Wiseman.]

The Consumer Representative on the FDA Committee, Dr. Jay Portnoy,  asked probably the most important question I’ve seen asked in any of these vaccine meetings. 

1:15  I’m confused about the dosing in terms of micrograms, because

Dr. Jay Portnoy, M.D.

Consumer Rep on the FDA’s VRBPAC (Vaccine & Related Biological Products Advisory Committee)  He asked the most important question that I’d see anybody ask in these hearings.  You’re dosing is 3mcg.  Moderna’s dosing is 25 mcg.  Clearly, we’re thinking of micrograms the way that we would think of proteins, a way of inducing an immune response.  Purpose of mRNA is to induce protein production.  So is your mRNA more efficient at making cells produce protein, or how shall we think of micrograms “in terms of the amount of spike protein that’s produced by the cells?” Can you kind of clarify that? 

Dr. William Gruber, Pfizer’s VP of vaccine clinical R & D

1:50  Yeah, I’ll leave it to Moderna to describe how they address their vaccine dosage.  But I think . . . “Obviously, we don’t have a complete understanding of the nature of the way the vaccine works.” In producing an immune results.   You have to go by the results! 

“But have you ever measured the amount of protein that’s produced as a result of the mRNA?” And how many cells are producing in it and how persistent that production is for a given microgram of mRNA?

That’s a pretty broad question. 

A fundamental scientific question is avoided.
