Tetanus shots should be given for deep wounds, soiled wounds, and wounds from rusty iron objects.
Tetanus bacillus is an anaerobic and conditionally pathogenic bacterium, which is suitable for proliferation under anaerobic conditions or when the wound is deep and infected with aerobic bacteria, and it grows in soil and rust, so tetanus injection should be given when there is a deep skin wound, a wound contaminated with soil, or a wound stabbed with a rusty iron or wooden thorn. Tetanus shots are also needed for burns, frostbite, gunshot wounds, avulsion wounds, and septic wounds.
Tetanus injection mainly includes tetanus vaccine and tetanus antitoxin. After injection of tetanus antitoxin, the human body can quickly obtain anti-virus antibodies, so as to have the ability to clear the virus; tetanus vaccine can produce active immunity through injection, but tetanus vaccine is slow to take effect.
If you have a skin break or a contaminated wound, you should consult a doctor in time, and you need to complete the relevant examinations under the guidance of a doctor to make a clear diagnosis, and you need to standardize the treatment.
