I'm afraid there is an obvious answer to that: the short answer is no. Through H1N1 I certainly came under a lot of criticism, as did the public health community, for—in the popular vernacular—having “changed our minds”, which really was a matter of applying new science.
I used the example of Tamiflu. Previously it was not considered effective, and we found that it was, no matter when you started it. It transformed the face of treatment in the pandemic.
We were accused of changing our minds about vaccine when we introduced an unadjuvanted vaccine. Well, we were seeing that some pregnant women were not comfortable with adjuvanted vaccine. The manufacturer was willing to produce it, and WHO was recommending it, if we had it. Initially it looked as though that would be a very smooth transition. As it turned out, it was much more complex than even the manufacturer anticipated, so we had some glitches. But we were able to provide that option for pregnant women.
So as we moved forward, yes, there were changes, but they were changes based on new science, and we have to apply that. I think it was Vincent Lam, who is an emergency room doctor and the author of Bloodletting and Miraculous Cures, who said that in the emergency department, if someone comes in with heart failure and doesn't respond to the usual drug, you don't say we have to use more of the usual drug; you have to change your strategy to respond to the patient in front of you. We have to change our public health strategies in response to the patient—which is the community—that we face as we go along and apply the best science we can, often in an environment in which we don't have all the data but we have good enough data to make a decision. And if we don't make a decision, that does condemn people to death.
