Final answer:
The tetanus vaccine is part of the regular vaccination protocol for humans and horses. Both humans and horses receive vaccines that include the tetanus toxoid. The CDC recommends multiple doses during childhood for humans and annual vaccinations for horses.
Step-by-step explanation:
The tetanus vaccine is part of the regular vaccination protocol for humans and is also crucial for the health of horses. Both species are commonly vaccinated against tetanus because they are susceptible to infections from Clostridium tetani, the bacteria that causes tetanus. The vaccine for tetanus in humans is often combined with other vaccines such as DTaP, Tdap, and Td, according to the CDC recommendations. These contain the tetanus toxoid (TT) for prevention of tetanus. Humans receive doses of the DTaP vaccine during infancy and early childhood, and the Td booster is recommended every 10 years. For horses, the vaccine helps prevent the disease, which can be fatal if contracted. It's a crucial part of regular equine health care and is typically administered annually to horses.
