2 Long lasting active protection
3 Immediate passive short term immunity
4 Stimulation for the production of antibodies
</span>
The correct answer is "immediate passive short term immunity". The administration of tetanus immunoglobulin will directly attack toxins associated with tetanus for a short time, providing short term immunity and this effect is immediate.The passive immunity from tetanus immunoglobulin is not lifelong. Choices 2 and 4 talks about active immunity which is not characteristic of tetanus immunoglobulin injection.
