>"Exposure Exposure was defined as receiving a first mRNA dose between May 1 and October 31, 2021. Individuals who were unvaccinated by November 1, 2021, were assigned a random index date based on vaccinated individuals’ vaccination dates."
What?? So any first mRNA dose before May 1st and after Nov 1st 2021 was not considered an adequate exposure? Why are they only defining exposure as the initial dose being administered within a six-month period for a vaccine that was released (A) before that; and (B) still continually offered - though in much lower capacities?
