The vaccinators checked the poliovirus vaccine
and organised the paperwork that would be filled with data of vaccinated children and handed over to the area in-charge on a daily basis.
Vaccines under the EPI are birth doses for hepatitis B and BGC, oral poliovirus vaccine
, pentavalent vaccine (antimeasles, measles, mumps, rubella) and tetanus toxoid.
Based on United Nations Children's Fund (UNICEF) and World Health Organization (WHO) estimates, national vaccination coverage among infants with 3 doses of oral poliovirus vaccine
(OPV [OPV3]) delivered through the routine immunization program was 72% in 2016, unchanged from 2014 and 2015 estimates (5).
Use of this inactivated poliovirus vaccine
and subsequent widespread use of the oral poliovirus, developed by Albert Sabin, led to the establishment of the Global Polio Eradication Initiative (GPEI) in 1988.
Success, in large part, has hinged on the use of trivalent, live attenuated oral poliovirus vaccine
(tOPV) throughout much of the world.
Current Advisory Committee on Immunization Practices recommendations specify four doses of trivalent inactivated poliovirus vaccine
(IPV) at ages 2 months, 4 months, 6-18 months, and 4-6 years.
Since the World Health Assembly endorsed a plan to completely eradicate polio in 1988, the large-scale use of the attenuated oral poliovirus vaccine
(OPV) has drastically decreased the number of polio cases.
There are two types of vaccines that can prevent polio: inactivated poliovirus vaccine
(IPV) and oral poliovirus vaccine
(OPV)," said HMC's Senior Consultant in Pediatrics Dr Magda Ahmed Youssef.
Endemic poliomyelitis has been eliminated from most parts of the world by vaccination with live attenuated oral poliovirus vaccine
(OPV) and inactivated poliovirus vaccine
The product is a four - component, combination Diptheria - Tetanus - acellular Pertussis (DTaP) and Sabin inactivated poliovirus vaccine
(sIPV) that was in Phase two of clinical development.
Lead author Dr Jacob John from Christian Medical College, India said that adding a supplementary IPV dose to children already vaccinated with oral poliovirus vaccine
(OPV) may hasten polio eradication by boosting herd immunity in endemic regions, acted as a booster to prevent international spread by travellers, and minimise the risk of polio outbreaks due to imported wildtype or vaccine-derived polioviruses.
Long-term visitors (those staying in Pakistan for more than four weeks) should receive a dose of oral polio vaccine (OPV) or inactivated poliovirus vaccine
(IPV) four weeks to 12 months prior to travel to Pakistan," he advised.
