Moderna Vaccine Batches and Toxicity – a full analysis
By Craig Paardekooper

Wide Variation in Toxicity Between Batches
Moderna deployed batches with varying toxicity. Some batches generate only 1 or 2 adverse
reaction reports, whilst others generate up to 5000 adverse reaction reports.

Interpreting a Moderna Batch Code

Two Main Groups of Batches – 20A and 21AA) 20A is most toxic
The 30 batches generating the most adverse reactions
are shown below. It can be seen that all of these end
with the letters 20A. All of the batches generating inexcess of 1780 adverse reaction reports have batch
codes ending in 20AB) 21A isBatches generating fewer than 1780 adverse reaction
reports have batch codes mostly ending in 21A. Batches
ending 20A are very infrequent at this lower level oftoxicity

The top 26 most toxic batches all belong to the 20AgroupSub Groups Within 20A
The sub groups within the 20A group are labelled J, K, L or M
These are in descending order of toxicity.

Sub Groups Within 21A
The sub groups within the 21A group are labelled A, B, C, D, E, F
These groups are in descending order of toxicity.

As you will see, subgroups denote different levels of toxicity. These follow a general trend of
decreasing toxicity as the alphabet is ascended
J>K>L>M
A>B>C>D>E>F

Number of Batches Within each Sub Group
This is a 3 digit number at beginning of the batch code. It simply tells you the number of the batch it does not tell you anything about toxicity.
Batches are normally numbered in sequence, i.e. they are normally accompanied by batches withadjacent numbers. The batch numbers do not always start at 1.
The number of batches in each subgroup can vary.
Batch numbers are unique within each subgroup – there is only one instance of each number.
Some batches within each group will likely be placebo – generating only 1 or 2 adverse reaction
reports, whilst others will be in the experimental group and generate high numbers of adverse
reactions.

We will now proceed to determine the toxicity level of each subgroup.

Boxplot of Subgroups
I used Excel to create a boxplot for all of the data above.
Each box shows the maximum and minimum, mean and interquartile range forthe adverse reactions produced by batches in each sub group.

As you can see, as the alphabet ascends, there is a progressive step by step decline in the toxicityof the batches.

Conclusion
There appears to be a zoning of toxicity levels such that
J>K
K>L
L>M
A>B
B>C
C>D
The point being that adverse reactions are not random.
Rather, they are determined by the toxicity of the vaccine batch, which is measured by the numberof adverse reactions to that batch.
And the toxicity of the batches have been found to vary systematically, in accordance with thealphanumeric batch code.
Batches of different toxicities have been assigned to different letters of the alphabet, and toxicity
decreases in steps as the alphabet ascends.

Additional Notes

1. Sometimes Moderna gives two batch codes for the same batch - so it halves the number ofadverse reactions
They only do this for very toxic batches e.g. 025J20-2A and 025J20A. They do this simply to lower theapparent number of adverse reactions – by splitting the adverse reactions between two slight
modifications of the same batch number. Clever, but deceptive.

2. Misspellings of Batches Increases the Number of Batches 100 fold and consequently
lowers the % of batches that are toxic
100 misspelled batches containing the letter J. Nearly all the misspellings are simply variations upon
two batches. This shows that a much greater % of batches may be highly toxic than was originally
thought. Here is a list of the misspellings.
