The tetanus toxin vaccine is used for emergency vaccination. The main ingredient of this vaccine is the tetanus antitoxin. It is best to be vaccinated within 24 hours, and the sooner the vaccination is administered, the stronger the potential for protection. However, the duration of protection provided by the vaccine is not very long, and the effect of the tetanus antitoxin medication generally lasts about a week. Therefore, vaccination within 24 hours can effectively prevent problems that may occur within that week.

Generally, there is no specific number for the annual frequency, but it is usually recommended not to exceed three times per year. Of course, this depends on the degree of injury. If there is a risk of infection, then the vaccine should be administered since its preventive effect is currently considered the best and can achieve significant efficacy.
