“If we don’t have adequate data in the greater-than-65-year-old group, then the greater-than-65-year-old person shouldn’t get this vaccine, which would be a shame because they’re the ones who are most likely to die from this infection,” vaccine expert Paul Offit said in a recent conversation with scientist Eric Topol.
