That is an extraordinary claim. Does someone else have a source to back that up? This argument would appear to vindicate the antivax movement, at least vis a vis whooping cough. That would be a shocking development.
The study, conducted on animals, does not, however, suggest that the vaccine increases rate of disease spread, rather that vaccinated individuals can serve as unaffected and unsuspecting nodes of transmission. This can happen with the acellular type of vaccine, not the whole-cell.
tl;dr: "We missed a spot." Which is going to happen. I don't think it validates being anti-every-vaccine, but it does validate asking questions and furthering research (and ceasing the vilification of the population that does ask questions!).
