] Reuven Cohen of Bar-Ilan University in Israel and his ] colleagues propose a simple modification of random ] vaccination that is more effective, according to their ] computer simulations. The idea is to randomly choose, ] say, 20% of the individuals and ask them to name one ] acquaintance; then vaccinate those acquaintances. ] Potential super-spreaders have such a large number of ] acquaintances that they are very likely to be named at ] least once, the researchers found. On the other hand, the ] super-spreaders are so few in number that the random 20% ] of individuals is unlikely to include many of them. Vaccinate Thy Neighbor |
