I keep my vaccinations current (hep A, hep B, typhoid, polio, yellow fever, MMR, tetanus) and take malarone when I'm in a malarial zone. But the frenzy for anti-bacterial wipes just makes me laugh. I believe 100% in "immunization by exposure" to general germs, and 100% in vaccination to guard against preventable diseases that can kill or permanently damage you. Science is a wonderful thing.
