The document will provide information for Ministries of Health and hospital sentinel sites on why and how to determine the denominator of at-risk children <5 years of age and rate of meningitis hospitalizations for a sentinel hospital site conducting IB-VPD surveillance. Such a methodology is curren...tly unavailable and this estimation is critical to enable interpretation of surveillance data, particularly pre- and post- vaccine introduction

Int J Vaccines Vaccin 2016, 2(1): 00018, January 29, 2016
WHO Guideline. Since 2010, countries in the meningitis belt have started to introduce a new serogroup A meningococcal conjugate vaccine conferring individual protection and herd immunity. Following the successful roll-out of this vaccine, epidemics due to Neisseria meningitidis serogroup A (NmA) are... disappearing, but other serogroups (e.g. NmW, NmX and NmC) still cause epidemics, albeit at a lower frequency and of a smaller size. Due to these changes, WHO organized the review of the evidence to provide recommendations for epidemic control, related to operational thresholds for investigation and response to outbreaks, the use of rapid diagnostic tests, antibiotic regimens in epidemics, and prophylaxis for household contacts of cases

The Global Vaccine Action Plan (GVAP) 2011-2020, endorsed by Member States during the May 2012 World Health Assembly, has set ambitious targets to improve access to immunization and tackle vaccine-preventable diseases. This responsibility has been translated into firm commitments in February 2016, t...hrough the signature of the Addis Declaration on Immunization (ADI) by African Ministers and subsequently endorsed by the Heads of States from across Africa at the 28th African Union Summit held in January 2017. This commitment from the highest level of government comes as a catalyst to immunization efforts on the continent to deliver on the promise of universal immunization

National Operationalisation Plan for the COVID-19 Vaccine : 13th edition
COVID-19 vaccine hesitancy is currently one of the main obstacles to worldwide herd immunity and socioeconomic recovery. Because vaccine coverage can vary between and within countries, it is important
to identify sources of variation so that policies can be tailored to different population groups. ...In this paper, we analyze the results from a survey designed and implemented in order to identify early adopters and
laggers in six big cities of Latin America. We find that trust in government and science, accurate knowledge about the value of vaccination and vaccine effects, perceived risk of getting sick, and being a student
increase the odds to get vaccinated. We also identify potential laggers as women and populations between 20 and 35 years old who are not students. We discuss specific strategies to promote vaccination among
these populations groups as well as more general strategies designed to gain trust. These findings are specific to the context of Latin America insofar as the underlying factors associated with the choice to be
vaccinated vary significantly by location and in relation to individual-level factors.

Rabies is a vaccine-preventable viral disease which occurs in more than 150 countries and territories. Dogs are the source of the vast majority of human rabies deaths, contributing up to 99% of all rabies transmissions to humans.
Rabies is a vaccine-preventable, zoonotic, viral disease affecting the central nervous system. Once clinical symptoms appear, rabies is virtually 100% fatal. In up to 99% of cases, domestic dogs are responsible for rabies virus transmission to humans. Yet, rabies can affect both domestic and wild an...imals. It spreads to people and animals via saliva, usually through bites, scratches or direct contact with mucosa (e.g. eyes, mouth or open wounds). Children between the age of 5 and 14 years are frequent victims.
