Poliovirus excretion following vaccination with live poliovirus vaccine in patients with primary immunodeficiency disorders: clinicians’ perspectives in the endgame plan for polio eradication

BMC Research Notes, 2018
Objective Primary immunodeficiency (PID) patients are prone to developing viral infections and should not be vaccinated with live vaccines. In such patients, prolonged excretion and viral divergence may occur and they may subsequently act as reservoirs ...

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

A RT-PCR method for selective amplification and phenotypic characterization of all three serotypes of Sabin-related polioviruses from viral mixtures

Memorias do Instituto Oswaldo Cruz, 2012
Outbreaks caused by vaccine-derived polioviruses are challenging the final eradication of paralytic poliomyelitis. Therefore, the surveillance of the acute flaccid paralysis cases based on poliovirus isolation and characterization remains an essential ...

A Personalised Vaccination Program Based on Immune Reconstitution in Paediatric Cancer Survivors

Acta Paediatrica, EarlyView.
ABSTRACT Aims Paediatric cancer survivors often experience treatment‐induced immunosuppression, requiring post‐treatment revaccination. However, immune recovery timelines vary, and current revaccination guidelines, largely based on data of varied quality derived from studies on acute‐lymphoblastic‐leukaemia (ALL), may not be applicable across all ...

A Global Perspective of Childhood Vaccinations: Past, Present, and Future—From Smallpox to mRNA

Acta Paediatrica, EarlyView.
ABSTRACT Childhood immunisation is one of the most successful public health interventions in history, preventing millions of deaths and substantially reducing global child mortality. This mini‐review summarises the historical development of childhood vaccines, the role of global coordination in expanding immunisation coverage, and the innovations that ...

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.

Case of Poliomyelitis Caused by Significantly Diverged Derivative of the Poliovirus Type 3 Vaccine Sabin Strain Circulating in the Orphanage

Viruses, 2020
Significantly divergent polioviruses (VDPV) derived from the oral poliovirus vaccine (OPV) from Sabin strains, like wild polioviruses, are capable of prolonged transmission and neuropathology. This is mainly shown for VDPV type 2.

Viral Aetiology of Acute Flaccid Paralysis Surveillance Cases, before and after Vaccine Policy Change from Oral Polio Vaccine to Inactivated Polio Vaccine

Journal of Tropical Medicine, 2014
Since 1992, surveillance for acute flaccid paralysis (AFP) cases was introduced in Malaysia along with the establishment of the National Poliovirus Laboratory at the Institute for Medical Research.
