if you look at the vaxxed documentary it is explained that the research skewed the criteria to make a more inclusive population that met their end result…. the doc who came in front of congress presented this data…
ts the MMR exactly in that age range (trivalent vs which they limited the exports of)… and more vulnerable to African American children…
If that is indeed true then i wonder if they get rid of MMR (trivalent form) or move to monovalent/divalent
