I do work for a bunch of pharmaceutical companies and developing nation health outreach type organizations. (Don’t ask me much technical, I’m not personally on the medical side.) But I can tell you that most major pharmas, Health NGOs and Government drug safety regulatory bodies are keenly aware that “Vaccines are a victim of their own success.” They have multiple approaches to dealing with the problem that a successful vaccine campaign makes the need for the vaccines socially invisible. There are varying degrees of success, but not a lot of generalized and reliable ways to combat this kind of cognitive disconnect.
