Isolation of a type 3 vaccine-derived poliovirus (VDPV) from an Iranian child with X-linked agammaglobulinemia.

Type 3 immunodeficiency-associated vaccine-derived polioviruses (iVDPVs) were isolated from a 15-month-old Iranian boy with acute flaccid paralysis (AFP) who was subsequently diagnosed with X-linked agammaglobulinemia (XLA). VP1 nucleotide sequences of the two isolates differed from Sabin 3 by 2.0% and 2.

Novel BTK mutation presenting with vaccine-associated paralytic poliomyelitis.

Oral polio vaccine (OPV) has been used safely and efficiently for more than 40 years in preventive medicine. Vaccine-associated paralytic poliomyelitis (VAPP) is a rare adverse event of OPV due to reversion of the vaccine strain virus to a neurovirulent strain. VAPP can occur in healthy recipients or their close contacts.

Vaccine-associated paralytic poliomyelitis in a patient with MHC class II deficiency.

Vaccine-associated paralytic poliomyelitis (VAPP) is a rare complication of oral polio vaccine. We describe a fatal case of VAPP in an 8-month-old boy with Major Histocompatibility Class II deficiency. The isolated poliovirus was a Sabin type 2-type 1 recombinant that showed 1.

Inadvertent rubella vaccination of pregnant women: evaluation of possible transplacental infection with rubella vaccine.

During mass campaign for measles/rubella vaccination on December 2003 in Iran, many pregnant women have vaccinated mistakenly. These women were grouped to susceptible and immune against rubella before vaccination by the status of IgG avidity response to rubella vaccine, then susceptible women were followed up to delivery time and their neonates were followed up to one year. In five neonates that were born from susceptible women, rubella-specific IgM has detected in cord blood sera, but they have not shown signs compatible to congenital rubella syndrome.
