You don't need tetanus shots until you're ten.

Patients under the age of 10 do not need tetanus, but tetanus vaccine in our body survival time is not very long, so no matter how old patients, when suffering deep or dirty wounds, should go to a tetanus shot, to prevent the display of tetanus caused by systemic tetanus spasm. The mortality rate of this disease is very high, so we do not encourage patients to keep fluke mentality, to go to the hospital in time to get tetanus treatment.
