The US military basic trainee, enlisting at pay grade E-1, would be paid $1,531.50 monthly. However, successful completion of basic training is usually accompanied by promotion to E-2, earning $1,716.90 monthly. This promotion requires a (usually pro forma) commander's waiver and reduction of the normal minimum requirement for time-in-grade (6 months in grade E-1) for promotion to E-2 after only 4 months in grade E-1.
Over time, protection from tetanus decreases, so older children need to get a booster shot. It has a full dose of tetanus and lower amounts of diphtheria and pertussis. All people between the ages of 11 and 18 are advised to get the booster, preferably around 11 or 12 years old.
Another shot is usually administered between the ages of 15 and 18 months, and again between the ages of 4 and 6. But these tetanus shots guard against disease only for so long, requiring adults to have repeated booster shots at least every 10 years. The 10-year duration of the tetanus shot requires vaccination against the clostridium tetani bacteria several times during an individual's life span.
