“…So, as expected, GMT values for poliovirus type 2 were always higher than those for poliovirus type 1 and both were higher than those for poliovirus type 3, when calculated by age group (Table 2). Studies conducted in the United States (1,8,13), Oman (17), Italy (2,6,12,(18)(19)(20), Finland (5), Israel (3), and South Africa (15) on antibody titers in OPV recipients monitored long-term concur with our results, demonstrating a decline in immunity and antibody geometric mean values. Overall, those surveys reported that the decline in immunity and GMT of neutralizing antibodies is related to intervals since the last OPV vaccination and not to gender, race, age at primary vaccination, or number of previous administrations.…”

“…Although polio immunity against paralysis does not wane substantially, immunity affecting susceptibility to infection and contagiousness does. Evidence of increasing susceptibility with waning immunity comes from antibody patterns (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16) and the relationships between antibody levels and protection against infection (17,18). Evidence of increasing contagiousness with waning immunity comes from the following: 1) an oral polio vaccine (OPV) challenge study demonstrating that persons with prior wild poliovirus (WPV) infection 40-50 years earlier excrete as much virus as completely susceptible persons (2); 2) an OPV challenge study in elderly populations demonstrating the association of excretion among previously vaccinated adults with antibody levels (19); and 3) recently immunized children who excreted significant quantities of WPV (20,21).…”

“…The waning of the antibody level with live polio vaccine is directly related to the time when the last dose of vaccine was given and not to the number of doses administered. 2 After the termination of the live vaccine era in Germany and the change to inactivated vaccine, the prevalence of type 3 antibody declined from 78% in 1990-1992 to 68% in 1997. Among children aged 5-14 years, the decline was from 74% in 1990 to 47% in 1997.…”
