re: #196 klystron

Tetanus and pertussis should be updated every 5-10 years or so and it is important to do those at a minimum because infants especially are vulnerable to pertussis.

Plus dying by tetanus is very unpleasant.

Many people who vaccinate their kids as infants and toddlers do not realize that a booster shot is required for teens.

How many high schools require a booster shot for all incoming freshmen?
