I donít really want to go through the article point by point. The best points in his favor are that we are talking about mass-use of first generation, experimental vaccines, against a class of virus that did not previously yield to vaccine development. I think the worst points he tries to make are that this has been a failure or is fraught with future danger. I think the most likely truth is that the vaccines are just not quite as effective as hoped, since both immunity and the disease are moving targets: At this point in any vaccine trial, one goes back to the drawing board and makes some improvements. Unfortunately these first generation vaccines have been so over-exposed that the public wonít tolerate a second round.
