Importation and Circulation of Vaccine-Derived Poliovirus Serotype 2, Senegal, 2020–2021

Emerging Infectious Diseases, 2022
Environmental surveillance for poliovirus is increasingly used in poliovirus eradication efforts as a supplement to acute flaccid paralysis (AFP) surveillance. Environmental surveillance was officially established in 2017 in Senegal, where no poliovirus

Impact of inactivated poliovirus vaccine on mucosal immunity: implications for the polio eradication endgame. [PDF]

, 2015
The polio eradication endgame aims to bring transmission of all polioviruses to a halt. To achieve this aim, it is essential to block viral replication in individuals via induction of a robust mucosal immune response. Although it has long been recognized

The Molecular Evolution of Type 2 Vaccine-Derived Polioviruses in Individuals with Primary Immunodeficiency Diseases

Viruses, 2021
The oral poliovirus vaccine (OPV), which prevents person-to-person transmission of poliovirus by inducing robust intestinal immunity, has been a crucial tool for global polio eradication.

The role of research in viral disease eradication and elimination programs: Lessons for malaria eradication [PDF]

, 2011
By examining the role research has played in eradication or regional elimination initiatives for three viral diseases-smallpox, poliomyelitis, and measles-we derive nine cross-cutting lessons applicable to malaria eradication.

Vaccine-related poliovirus shedding in trivalent polio vaccine and human immunodeficiency virus status: analysis from under five children

BMC Research Notes, 2017
Background Poliomyelitis is an acute viral infection caused by poliovirus and transmitted via the fecal–oral route. The causative agent is one of the three serotypes of poliovirus (serotypes 1, 2, 3) that differ slightly in capsid protein.

First report of a persistent oropharyngeal infection of type 2 vaccine-derived poliovirus (iVDPV2) in a primary immune deficient (PID) patient after eradication of wild type 2 poliovirus

International Journal of Infectious Diseases, 2019
This is the first report of persistent oropharyngeal mucosal infection with type 2 poliovirus (iVDPV2) in a primary immune deficient patient (PID) after wild type 2 poliovirus eradication. The iVDPV2 also established persistence in the gut.

Hospital discharges-based search of acute flaccid paralysis cases 2007-2016 in Italy and comparison with the National Surveillance System for monitoring the risk of polio reintroduction [PDF]

, 2019
Background: Acute flaccid paralysis (AFP) surveillance has been adopted globally as a key strategy for monitoring the progress of the polio eradication initiative.

Poliovirus-specific memory immunity in seronegative elderly people does not protect against virus excretion. [PDF]

, 2005
BACKGROUND: Dutch people born between 1925 and 1945 were ineligible for vaccination with the inactivated poliovirus vaccine (IPV) introduced in 1957 and may have escaped natural infection because of reduced poliovirus circulation.

Deconvolving mutational patterns of poliovirus outbreaks reveals its intrinsic fitness landscape. [PDF]

, 2020
Vaccination has essentially eradicated poliovirus. Yet, its mutation rate is higher than that of viruses like HIV, for which no effective vaccine exists.
