The Purchasing agreement that Pfizer was forcing nations to sign has been leaked. (We've heard bits of this before). T
his is the example that South Africa signed.
Purchaser acknowledges that the vaccine and materials related to the vaccine, and there are components and constituent materials, are being rapidly developed due to the emergency circumstances of the COVID-19 pandemic and will continue to be studied after provision of the vaccine to purchaser under the agreement. Purchaser further acknowledges that the long-term effects and efficacy of the vaccine are not currently known and that there may be adverse effects of the vaccine that are not currently known. Further, to the extent applicable, purchaser acknowledges that the product shall not be serialized.
So when they were telling you it was all good, they were LEGALLY binding contracts stating the opposite.
What I find interesting is that Pfizer prohibited serialization of the product. That's because they DIDN"T want traceability. I've worked in pharma related industries (MGF QA) and even worked with start ups making PCR tests. Pfizer DID NOT WANT lot based and serialization traceability which is a 180 opposite for what they were doing (exerimental mRNA shots). In fact they make sure that single lots do not get sent to a single state/province so that lot clustered side effects are more difficult to find. (If one lot went to Philly and Philly experiences an uptick in cancer they WANT that harder to ID)
I've also read that there is a potential to get around the producer liability exclusions due to the experimental nature of the clot shots based on the fact that it appears that there were components in the shots that were not disclosed. There is still some uncertainty on this as the vials that were tested by independent labs were not obtained formally. In other words, Pfizer won't provide samples.. and those that have been tested were pulled from the pipeline (more likely to be representative) but the argument then is that their chain of custody is suspect.
Regardless, the wall gets chipped away at slowly but surely.
