Although epidemiologic data about smallpox disease is substantial, one of the difficulties of relying on historic data to assess smallpox infectivity is the fact that these data were collected in a context of significant population immunity. Most babies born to women who got smallpox vaccine will be fine. In a person with normal immune function, neutralizing antibodies appear about 10 days after primary vaccination and 7 days after revaccination.
