After administering an antibody product, how long should you wait before giving a live vaccine?

  1. 2 weeks

  2. 1 month

  3. 3 months

  4. 6 months

The correct answer is: 3 months

After giving an antibody product, it is recommended to wait at least 3 months before administering a live vaccine. This is because the antibodies from the product can neutralize the effectiveness of the vaccine and reduce its ability to produce an immune response. Waiting for 3 months allows the antibodies to decrease in the body, allowing the vaccine to work properly. The other options, 2 weeks, 1 month, and 6 months, may be too short or too long of a wait time and can potentially result in a reduced effectiveness of the vaccine.
