Health policy is best when it stands on the shoulders of rigorous scientific research—for example, restricting tobacco makes sense because it’s proven to reduce cancer rates and mortality. But sometimes health policy is built on a slightly shakier premise; one that balances sound science with the need to avoid controversy. The government’s policy on the pandemic swine flu vaccine is an example of this latter approach.
The decision to make the vaccine voluntary for health care workers (except in New York) is one way the government has avoided public outcry. The decision by the Center for Disease Control to not add adjuvants—substances that activate the immune system and make the vaccines more powerful—to the shots, even though doing so would have helped alleviate the delays and shortages we are currently experiencing, is another. Neither of these decisions was rooted in evidence-based concerns about public safety. And they ultimately reduce the widespread health benefits of the vaccination campaign.
