In 2020, Nigeria celebrated a significant milestone when the World Health Organization (WHO) certified the nation as free from the Wild Polio Virus (WPV). However, experts caution that this achievement does not mark the end of the journey; rather, it serves as a critical opportunity to eliminate all forms of poliovirus transmission. Strengthening Routine Immunization (RI) is essential to maintaining this progress, especially in light of the recent rise in Circulating Vaccine-Derived Poliovirus Type 2 (cVDPV2) cases.

Recent findings indicate a concerning trend in 2023, with a spike in cVDPV2 cases across Nigeria, particularly in the states of Zamfara, Sokoto, Kebbi, Katsina, and Kano. Alarmingly, over 556,750 children in Kano, Jigawa, and Katsina, areas supported by the United Nations Children's Fund (UNICEF), have not received a single dose of the vaccination they need. This neglect accounts for approximately 88% of the 238 traced cVDPV2 cases.

Mr. Michael Banda, Officer-in-Charge at the UNICEF Field Office in Kano, expressed deep concern over the high number of unvaccinated children, emphasizing the threat it poses to Nigeria's hard-won polio-free status. "It’s like killing the snake in your backyard without addressing the eggs it laid," he warned. To safeguard Nigeria’s polio-free status, ongoing routine vaccination campaigns are crucial.

In alignment with these sentiments, Dr. Mohammed Nasir Mahmoud, Director General of the Kano State Primary Healthcare Management Board, reaffirmed the state's commitment to enhancing primary healthcare facilities to ensure effective immunization. He highlighted the importance of protecting the future by safeguarding the health of children, noting that poliomyelitis primarily affects those under five years of age, with one in 200 infections resulting in irreversible paralysis and a 5-10% mortality rate among those affected.

Dr. Mahmoud celebrated the remarkable decline in wild polio cases, which have dropped by over 99% since 1988, from an estimated 350,000 cases across more than 125 endemic countries to just two endemic countries as of October 2023. However, he stressed that the issue of unvaccinated children must be addressed to prevent a reversal of these achievements. "As long as a single child remains infected, all children are at risk," he cautioned, underlining the potential for a global resurgence of the disease if polio is not eradicated from the last remaining strongholds.

UNICEF behavioral change specialist Dr. Ogu Enemaku also highlighted the vital role of media professionals in addressing these challenges. He urged journalists to engage responsibly with communities during outbreaks, adhering to ethical guidelines to ensure their messaging is both effective and respectful.

The road ahead requires a united effort to maintain and expand vaccination initiatives, ensuring that Nigeria's progress against polio is not only celebrated but secured for generations to come.
