Tetanus infection can be a common disease if people had not taken enough care to prevent it. The bacterium causing tetanus lives in our environment, in the soil and animal feces. It gets into the human body through cuts and open wounds.
We often hear people telling us that we need to take a tetanus injection when we cut ourselves with a knife that is rusty or if a nail pokes us. Tetanus is a disease that is caused by a strain of bacteria, which adversely affects the CNS (central nervous system) and leads to the paralysis of the entire body. All this can progress very fast ending in death. Tetanus-causing bacteria can get into the body only when the wounds or cuts are very deep. That is why when children hurt themselves very badly, they are immediately given tetanus injection to prevent the fatal bacteria from entering the body.
In the United States, tetanus injection is included in the normal immunization chart for children. It is given to newborn babies and then repeated two to three times during their vaccination schedule. However, as a protocol, whenever a child is injured very badly and has open and deep wounds, a tetanus shot is given as a protocol.
One tetanus injection can protect for at least 10 years after which it has to be renewed for the person. However, in the mean time, if a person has been an accident or suffers a bad injury, the vaccination is given. There is no harm in repeating the tetanus shots and it is only for additional safety. That is why one has to update their shots and vaccination records every year.
