As the swine flu fiasco fades into the past, many people are breathing a sigh of relief; some because they were worried about getting sick, and some because they were sick of hearing about it. Since it all began, I’ve spent innumerable hours reading about the virus and vaccine. I read the peer-reviewed literature, newspaper articles, science blogs, magazine features, and vaccine package inserts. I read the unscientific stuff too; the conspiracy theories and the sensational reports of rare side effects.
I have come to a few conclusions. First of all, we can’t all make fully informed decisions about such issues. There is too much information and there are too many issues. Where do I stand on the issue of global warming? I hesitate to say; I spent all of my free time reading about the swine flu.
For many people, the quality of the information is as problematic as its quantity. The primary literature isn’t written in a way that is comprehensible for those who have no knowledge of medicine, statistics, and research design. The mainstream media conveys information in ways that are easier to understand, but the message ultimately depends on the source. Reports from the National Vaccine Information Center and the CDC in the United States, for example, would lead people to markedly different conclusions.
Perceptions of credibility are variable and subjective, and members of the public are ill-equipped to distinguish reliable evidence from sensationalism. For these reasons, it is crucial that the public be able to trust scientific authorities and government agencies to advise them appropriately. For a mass vaccination effort to be successful, people need to believe that authorities hold their health and safety as top priorities. Many people do not believe that this is the case. Their doubts may well be justified.
On various internet forums, ardent science defenders tossed insults and ridicule at the anti-vaccine crowd. They raved about the “overwhelming evidence” and “solid science” as if they have read all of it and judged it for themselves. The heart of the problem, however, is not the evidence or the quality of it, but the perceived lack of credibility of the authorities. In this respect, and this respect alone, I do sympathize with the anti-vaccine perspective. The authorities who are supposed to be ensuring our health and safety do not have a good track record.
