Oral Poliovirus Vaccine (OPV) Manufacturing in Iran over Five Decades: from tOPV to bOPV and Future Planned Cessation [PDF]

open access: yesArchives of Razi Institute
By the early 1970s, there were no manufacturers in Iran producing oral poliovirus vaccine (OPV). The only domestic OPV was produced by the Razi Vaccine and Serum Research Institute (RVSRI) in 1974 after receiving the Sabin seeds on 5 January 1973.

Oral polio revaccination is associated with changes in gut and upper respiratory microbiomes of infants

open access: yesFrontiers in Microbiology, 2022
After the eradication of polio infection, the plan is to phase-out the live-attenuated oral polio vaccine (OPV). Considering the protective non-specific effects (NSE) of OPV on unrelated pathogens, the withdrawal may impact child health negatively ...
