The programme from July 7 to 11 will cover seven townships in Kayin, three in Mon, and two in Bago, according to a statement by the Ministry of Health and Sports. 

The vaccinations will cover children under 15 only in Hpapun township, Kayin, and those under five in the other 11 townships. It is estimated that 300,000 youngsters will receive the polio vaccines.

"Vaccine-derived poliovirus type 1, or VPDP1, can infect children who have never been inoculated with the polio vaccine, so every child absolutely needs to take part in the vaccination programme," Htar Htar Linn, programme manager of the department's Extended Programme on Immunisation said.

The vaccination campaign was ordered after a child in Sin Swel village near Hpapun township, Kayin, was found to have contracted the VPDP1 virus in June. The virus was confirmed by testing at Myanmar's National Health Laboratory and the Specialised Polio Laboratory in Mumbai, India, on June 23.

A field investigation team with representatives from the department's Contagious Disease Prevention and Extended Programme on Immunisation, the National Health Laboratory, Yangon Children's Hospital, the Public Health University, the World Health Organization, and the United Nations Children's Fund conducted studies in Hpapun from June 24 to 26. 

According to the findings of the investigation team, there has been no polio vaccination programme in 249 out of 313 villages in Hpapun due to armed conflicts in the area. 

According to the Global Polio Eradication Initiative, vaccine-derived polioviruses are a rare strain of poliovirus that have genetically mutated from the strain contained in the oral polio vaccine. The oral polio vaccine contains a live, attenuated (weakened) vaccine-virus. 

When a child is vaccinated, the weakened vaccine-virus replicates in the intestine and enters into the bloodstream, triggering a protective immune response in the child, providing immunity to polio. Like wild poliovirus, the child excretes the vaccine-virus for a period of six to eight weeks.
