Nigeria's government is challenged with vaccinating the world's third largest birth cohort within a culturally and socioeconomically diverse country. This study estimated full childhood immunization coverage in Nigeria and characterizes the association between vaccination status and urbanicity, region of residence, ethnicity, and other factors. ⋯ Full vaccination among children in Nigeria is exceptionally low by global standards and certain groups, such as Muslims and individuals in northern regions who are higher risk of non- or under-vaccination should be targeted by vaccination programs. Providing a wide range of health care services for mothers and pregnant women could improve full vaccination of children.

Comparative Study
Recent vaccine mandates in the United States, Europe and Australia: A comparative study.
In response to recent outbreaks of vaccine-preventable diseases and concerns around vaccine refusal, several high-income countries have adopted or reformed vaccine mandate policies. While all make it more difficult for parents to refuse vaccines, the nature and scope of 'mandatory vaccination' is heterogeneous, and there has been no attempt to develop a detailed, comparative systematic account of the possible forms mandates can take. ⋯ We suggest that politico-cultural context and vaccine policy history are centrally important factors for vaccine mandate policymakers to consider. It matters whether citizens trust their governments to limit individual freedom in the name of public health, and whether citizens have previously been subjected to vaccine mandates. Furthermore, political communities must consider the diverse mechanisms by which they may construct vaccine mandate policies; whether through emergency decrees or ordinary statutes, and how (or whether) to involve various stakeholder groups in developing and implementing new vaccine mandate policies.

All six World Health Organization (WHO) regions have committed to eliminate measles, and three WHO regions have committed to eliminate rubella. One of the key tenets of measles and rubella elimination is to have a strong surveillance system in place. The presence of a case-based measles and rubella surveillance system that is national, population-based, provides laboratory confirmation, and directs action, is one of the requirements for elimination-standard surveillance. ⋯ Many countries reported having some of the essential components in place to conduct elimination-standard surveillance for measles and rubella; however, in order to achieve elimination, the quality of surveillance needs to improve to detect all cases. In those countries without these essential components of elimination-standard surveillance, the first step is to implement these components.

Ghana introduced the monovalent rotavirus vaccine (Rotarix) into its national paediatric vaccination programme in May2012. Vaccine introduction was initiated nationwide and achieved >85% coverage within a few months. Rotavirus strain distribution pre- and post-RV vaccine introduction is reported. ⋯ Rotavirus G1P[8], the major strain in circulation during the pre-vaccination era, was replaced by G12P[8] as the most predominant strain after vaccine introduction. This strain replacement could be temporary and unrelated to vaccine introduction since an increase in G12 was observed in countries yet to introduce the rotavirus vaccine in West Africa. A continuous surveillance programme in the post-vaccine era is necessary for the monitoring of circulating rotavirus strains and the detection of unusual/emerging genotypes.

Group A streptococcus (GAS) causes an exceptionally diverse range of diseases, raising questions about the optimal product characteristics of a commercially viable vaccine. The objectives of this study were to (1) estimate the current health and economic burdens caused by 24 diseases attributable to GAS each year in Australia and (2) use these estimates to explore the value of a GAS vaccine for different clinical indications, age schedules, and population groups. ⋯ A vaccine that prevents GAS cellulitis and other skin infections, in addition to throat infections, would maximise its value and commercial viability, with a cost-effective price in line with other recently-licensed and funded vaccines in Australia.
