So snarks Jill Filipovic (boldface mine):
According to a recent study, giving children tetanus shots will not, in fact, encourage them to stab themselves with rusty nails or be less cautious when playing outdoors. Various political organizations have advocated against the tetanus vaccine, arguing that tetanus shots send the message that recreation is acceptable, and that if children know they’re protected from lockjaw, they will be less vigilant about avoiding the kinds of cuts and scrapes that can lead to deadly nervous system infections. Attempts to require tetanus vaccination have met extreme backlash from conservative groups who argue that mandating the vaccine is an assault on parental rights and family values.
Even bills that simply would have made the vaccine free for low-income children without mandating it were vetoed by Republican governors. Doctors hope that these study results, which show that tetanus-vaccinated children are no more likely to engage in unsafe recreational behavior than their unvaccinated peers, will increase the tetanus shot rate for children of parents who fear that tetanus shots encourage risk-taking.
As the kids say, read the whole thing.
