My girlfriend's doctor told me to get a tetanus shot?
My girlfriend is 34 weeks pregnant, and the last few nights, she's been up every hour or two, saying her ears and throat hurt, and using vicks vapo rub. Thinking it was allergies, the last two days, I had given her zyrtec, but it didn't help her. This morning, she violently vomited yellow mucus all over the bathroom, so I called her doctor and made an appointment. The doctor just prescribed zyrtec for her, and a nasal spray.
Anyway
The doctor told me that I need to get a flu shot and a tetanus shot, so that I won't be a source of sickness for my new family before the baby is healthy enough to get her own shots.
Why do I need to get a tetanus shot?
