The NDC is the National Drug Number
From the Jansen website:
The 3 segments of the NDC identify: the labeler, the product, and the commercial package size.
The first set of numbers in the NDC identifies the labeler, such as the drug manufacturer, repackager, or distributer.
The second set of numbers is the product code, which identifies the specific strength, dosage form (i.e, capsule, tablet, liquid) and formulation of a drug for a specific labeler.
Finally, the third set is the package code, which identifies package sizes and types.
the last number 1 would be placebo, 2, mRNA , 3, mRNA + cancer causing Adenovirus
On each bottle there is a number, this number matches the packaging box, on the packaging box you can see the last number, 1, 2, or 3 !
