Albert Bourla on why mRNA technology was “counterintuitive“ to producing an effective vaccine

“It was counterintuitive because Pfizer was mastering or let’s say we had very good experience and expertise with multiple technologies that could give a vaccine…mRNA was the technology that we had less experience with, only two years working on this. And actually, MRNA was a technology that never delivered a single product until that day. Not vaccine, not any other medicine, so it was very counterintuitive.”- Albert Bourla
