If vaccines are as bad as anti-vaccine people and groups claim that they are, where is the evidence? We've seen other diseases and conditions be identified and dealt with. Why not these bad vaccine outcomes? Could it be that it's not as bad as antivaxxers say it is?
Anecdotes are not data, but they could be canaries in the coal mine that are still worth looking into. If we don't do due diligence and look into them, what could happen? What could we delay or even miss out on doing?
