Question explored with the scientific record
How did they decide who got which batch of vaccine in the UK? We're patients pre selected for a deadly dose?
The short version: no evidence in this retrieval shows anyone was preselected for a harmful batch, and the question itself is not answerable from these records.
The records here are about manufacturing systems, batch consistency, and contamination detection, not about how the UK assigned batches to patients. One study shows strong batch-to-batch consistency in a COVID spike protein vaccine across three lots [5]. Another documents DNA contamination in Comirnaty batches, with 3,600 to 5,340 ng of DNA per dose across all seven batches tested [21]. That is a real finding, but it does not tell you who got which batch or whether any patient was targeted.
What the evidence does show is that batch quality varies and that contamination happens. A 2011 study found infectious RD-114 retrovirus in two canine vaccine batches, with one batch negative and one positive per vaccine [9]. A 2016 study detected reticuloendotheliosis virus contamination in live poultry vaccines [17]. These are animal vaccines, not UK COVID jabs, but they establish the general point: batch-to-batch differences are real, and regulators do not always catch them.
| Finding | What it shows |
|---|---|
| Comirnaty DNA contamination | 3,600–5,340 ng DNA per dose, all 7 batches [21] |
| Canine vaccine contamination | RD-114 virus in some batches, not others [9] |
| Poultry vaccine contamination | REV virus detected in live vaccines [17] |
The claim that patients were preselected for a deadly dose has no support in these records. It is not the kind of thing batch manufacturing studies would reveal either way. What the records do support is that batch quality is not uniform, that contamination has been documented repeatedly, and that the systems meant to catch it rely on testing that can miss problems. The most informative study, tracking which patients got which batch and comparing outcomes, is not in this retrieval.
My call: the evidence does not show preselection, but it does show batch contamination is a documented pattern, not a fantasy. Confidence: not clear on the preselection question; moderate on the claim that batch quality varies.

In-depth characterization of protein N-glycosylation for a COVID-19 variant-design vaccine spike protein
Characterization of N-glycosylation on a CHO-K1–expressed, six-proline–stabilized SARS-CoV-2 spike variant identifies 19 N-glycosites and 31 predominant N-glycans, with strong batch-to-batch consistency across three manufactured lots.

Contamination of infectious RD-114 virus in vaccines produced using non-feline cell lines
Two canine vaccines produced using non-feline cell lines were found to be contaminated with infectious RD-114 retrovirus, detected by RT-PCR, real-time RT-PCR, LacZ marker rescue assays, and proviral DNA testing, suggesting seed-virus contamination during attenuation and highlig…

Development of a real-time quantitative RT-PCR to detect REV contamination in live vaccine
A real-time quantitative RT-PCR targeting the REV pol gene was developed to detect reticuloendotheliosis virus contamination in live vaccines (FPV and MDV), achieving ~10,000-fold greater sensitivity than conventional RT-PCR with high specificity and reproducibility.
