Acceptability and Feasibility of Human Papillomavirus Vaccine Introduction in Cameroon: A Mixed-Methods Study.

Introduction: Human papillomaviruses (HPV) are responsible for sexually transmitted infections, and some of these viruses have oncogenic potential. The HPV vaccine is due to be introduced in Cameroon in September 2019. Our study looked at the knowledge, perceptions, and attitudes of the population and healthcare professionals regarding cervical cancer and its vaccine prevention.

The Polio Vaccination Status of Non-polio Acute Flaccid Paralysis Cases in the Far North Region of Cameroon: A Five-Year Retrospective Study From 2015 to 2019.

Background:  The Expanded Program on Immunization (EPI) of Cameroon contributes to the reduction of polio, but the rate of non-polio acute flaccid paralysis (NPAFP) is still high. The aim of this study was to describe the immunization profile of NPAFP cases and the performance of polio surveillance in the Far North Region of Cameroon between 2015 and 2019.

Methods: A retrospective secondary data analysis was conducted using the national EPI and regional AFP surveillance case-based database from 2015 to 2019.

Innovative approach in assessing the children's immunization status when it cannot be documented.

During surveys, it is recommended that children immunization status should be based on immunization documents. It has been noted that in some communities, a number of children are claimed to be vaccinated but have no evidence of vaccination. This work is proposed to estimate routine immunization coverage in children based on both documented vaccination and the tracking of undocumented immunization.

Effect of COVID-19 on immunization coverage of children aged 0-11 months in the center region of Cameroon.

The occurrence of epidemics is known to contribute in reducing the capacity of health facilities to deliver care and the predisposition of populations to seek care through several mechanisms. The objective was to assess the effect of the COVID-19 on vaccination coverage of the expanded program of immunization (EPI) vaccines in children aged 0-11 months. The study involved a descriptive and case control designs exhaustively targeting health facilities in health areas from selected health districts.

Program on immunization and cold chain monitoring: the status in eight health districts in Cameroon.

Background: Cold chain monitoring is a precondition to ensure immunization quality, efficacy and safety. In Cameroon, the Expanded Program on Immunization (EPI) has National Standard Operating Procedure (SOP) that describes the vaccines, the cold chain system and equipment, its use and recommended procedures to control and monitor the temperatures and the cold chain. This study was conducted to assess the status of cold chain in eight health districts in Cameroon.
