This is the name given to people who, without having any knowledge about vaccines, the immune system or medicine, harangue us to vaccinate those of us who feel obliged to make use of common sense and not call a genetic treatment a vaccine. You can apply this term to describe more than one expert with an academic degree who claims to defend science but ends up blocking you in the networks if you show him what science really says and who shows that his knowledge does not happen to be better than that of any brother-in-law.
