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.

Deficiency of immunity to poliovirus type 3: a lurking danger? [PDF]

, 2012
Background: Europe was certified to be polio-free in 2002 by the WHO. However, wild polioviruses remain endemic in India, Pakistan, Afghanistan, and Nigeria, occasionally causing polio outbreaks, as in Tajikistan in 2010.

COVID-19 Infection Among Women in Iran Exposed vs Unexposed to Children Who Received Attenuated Poliovirus Used in Oral Polio Vaccine

JAMA Network Open, 2021
Key Points Question Is indirect exposure to live attenuated poliovirus in the oral polio vaccine (OPV) associated with diminished symptomatic infection with SARS-CoV-2? Findings In this cohort study of 4190 women in Iran, none of those indirectly exposed

Oral and inactivated poliovirus vaccines in the newborn: A review [PDF]

Vaccine, 2013
Oral poliovirus vaccine (OPV) remains the vaccine-of-choice for routine immunization and supplemental immunization activities (SIAs) to eradicate poliomyelitis globally. Recent data from India suggested lower than expected immunogenicity of an OPV birth dose, prompting a review of the immunogenicity of OPV or inactivated poliovirus vaccine (IPV) when ...

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.

The Early Evolution of Oral Poliovirus Vaccine Is Shaped by Strong Positive Selection and Tight Transmission Bottlenecks

bioRxiv, 2020
The evolution of circulating vaccine-derived polioviruses (cVDPV) from components of the live-attenuated oral poliovirus vaccine (OPV) presents a major challenge to global polio eradication.

A Health Economic Analysis for Oral Poliovirus Vaccine to Prevent COVID‐19 in the United States

Risk Analysis, 2020
COVID‐19 led to a recent high‐profile proposal to reintroduce oral poliovirus vaccine (OPV) in the United States (U.S.), initially in clinical trials, but potentially for widespread and repeated use. We explore logistical challenges related to U.S.

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.
