I need help with this long sentence it's about the efficacy of influenza vaccine.
In healthy primed adults, the efficacy after one dose may be as high as 80-100%, while in umprimed adults (those receiving their first influenza inmunization), efficacy is in this range after two doses.
En el primer caso creo que se trata de adultos jovenes sanos porque he leido textos paralelos, pero Unprimed adults a que se refiere (ya que segun algunos textos dice que aquellos que no han recibido la vacuna son los menores de 9 años) So why adults???
Does someone know?
Can anyone help me, please?
