- In Rh disease of the newborn, maternal antibodies enter fetal circulation and destroy the red blood cells of the fetus. A mother with type O blood has anti-A and anti-B antibodies, but may have a dozen type A children without any problem at all. Explain why.
- Everyone should have a tetanus booster shot every 10 years. That is what we often call a “tetanus shot”.

Explain the difference, and why TIG is so important.
