- 3 year time-frame for whooping-cough vaccine; kids need to re-up source
- » Or hope everybody covers their mouths? The study, presented by lead researched Dr. David Witt at an infectious diseases conference in Chicago, determined that the vaccine’s effectiveness drops off dramatically three years from when it was administered — compared to a recently vaccinated child, for example, the odds of infection are nearly twenty times higher. This has bolstered support for mandating a repeat of the vaccination for public schoolchildren, as California notably experienced a whooping-cough outbreak last year that killed ten babies. Of course, mandated vaccinations are oft-considered controversial, at times based on scurrilous reasoning.
