How Long After Cut Tetanus Shot (And Why)?

Exact Answer: Within 2-3 days

Getting cut or injured is one of the painful experiences. Once the pain settles down, the foremost step should be to take care of the wound. Few wounds which do not break the skin can be cured with home remedies or bandages, but some cuts and injuries require medical treatment because there is probably a high chance of getting infected with tetanus.

Tetanus can be prevented by receiving a vaccine or tetanus booster earlier as per the schedule. Although this vaccine does not last forever, it can prevent immediate effects and a vaccine should be updated at least every 8-10 years to gain enough immunity against Tetanus.

As there is no permanent cure for this, you should be very careful regarding this infection. After cleaning the wound, observe the wound for the next couple of hours for any significant signs of infections.

  The bacteria which causes tetanus enters the body through a wound or cut and often they are found in soil particles. The tetanus shot must be given as soon as possible but in few unavoidable situations, it can be still be given within around 24-48 hours of the wound or cut to escape from contracting bacterial infections like tetanus.

Tetanus may develop when your wound is in contact with soil or rusty objects or when there is a break in the skin. It can affect the nervous system too. Professionals generally recommend receiving a tetanus booster or shot in probably two cases as follows.

Though the wound is clean, if you haven’t received any tetanus booster for the past 10 years, it is highly suggested to receive it immediately. And if the wound is dirtier than expected and you haven’t had a booster for the past 5 years, then it is recommended to have one.

If you are not sure about the date of the last vaccine and you have got a cut, it is far better to receive a tetanus shot within 48 hours of injury than being infected heavily. The size of the wound never matters in case of Tetanus infection.

And Tetanus depends on several important components such as wound nature, no. of vaccinations took already, and also on the date of the last booster. Despite being dangerous, it can be fatal only in very rare cases when it is left untreated and does not show any adverse effects.
