Vertaling van "antibody treatment would " (Engels → Frans) :

If there are a small number of people who might contract Ebola, the monoclonal antibody treatment would be used. If there were a large number of people who might get Ebola, they would be vaccinated beforehand.
Par contre, les grands groupes de gens à risque seraient vaccinés à l'avance.

In other words, if someone has a certain antibody count, or however you gauge it, then the testing would be beneficial for knowing whether to continue treatment or not.
Autrement dit, si quelqu'un a un certain nombre d'anticorps, peu importe comment on l'évalue, à ce moment-là le test permettrait de juger si l'on doit poursuivre le traitement ou non.
