An individual with an uncertain vaccine history has been brought to the emergency room after receiving severe lacerations in an accident with farm machinery. In addition to administering a tetanus toxoid vaccine, he is given a shot of tetanus immune globulin (TIG), a form of passive immunization. Why are both necessary?

A) The tetanus vaccine provides immediate protection, and the tetanus immune globulin provides long-term protection. B) The doctor is not sure which will work faster in this patient so decides to administer both. C) The tetanus immune globulin is given only when there are severe injuries and a high risk of infection. D) Tetanus immune globulin is always given along with the tetanus vaccine. E) The tetanus immune globulin provides immediate, short-term protection, and the tetanus vaccine provides long-term protection.

E) The tetanus immune globulin provides immediate, short-term protection, and the tetanus vaccine provides long-term protection.

Explanation:

Basically, immunization is very important and necessary to protect the person from diseases.

In the above scenario, individual who is injured with severe lacerations does not have any history of previous tetanus vaccination. Because vaccination is for long term protection but it also take time to produce antibodies in an individual. Individual is injured and can have risk of tetanus.

So, along with vaccine we will administered the tetanus immune globulin to provide immediate, short term protection against tetanus.
