- jwineinger 5y agoWhen the CDC released the statement that you could mix, my dad (a physician) was a bit upset. I remember him telling me that they seem to have based that on a single paper that had a sample size far too small to generalize for the different combinations of vaccines, age groups, genders, and races.
