DNA contamination in 8 vials of Pfizer monovalent mRNA vaccines

Conclusions

8/8 monovalent vaccines sourced from a single case from a single lot of Pfizer monovalent vaccines all fail the EMA specification of 3030:1 RNA:DNA (330ng/mg DNA/RNA). They are over the limit by an order of magnitude (18-70 fold). The DNA contamination is very consistent and the vial to vial ratio of RNA:DNA is very consistent within the same lot of monovalent vaccines. Further sequencing is underway to evaluate the 72bp heteroplasmic indel in the SV40 promoter of the vector. This was detected in the Pfizer bivalent vaccines.
