Tom's wife told the Dr. that the treatment was redundant and overkill. She insisted it was just another way for the doctor to make more money. (3pts) Based on your knowledge of humoral immunity, explain: Why the Dr's treatment strategy for Tom (both tetanus shot and tetanus booster vaccine) is logical rather than away to make more money 2.

1. Doctor has rightly given Tom a tetanus antiserum shot to provide him artificial acquired passive immunity against tetanus.
