The Zambia Population Based HIV impact assessment of 2016, reported the prevalence of viral hepatitis in Zambia as ranging between 5.6% among adults aged 15 to 59% in the general population, and 7.1% among HIV infected individuals. It is estimated that the majority of persons with chronic hepatitis

B and/ or hepatitis C are unware of their infection and do not benefit from promotive, preventive and curative services designed to reduce onward transmission. Zambia introduced hepatitis B virus vaccine to the routine Under 5 vaccination schedule in 2005. Preliminary results from the ZAMPHIA indicate that hundreds of infections have been abated in children since then. However, its also clear that we continue to miss key opportunities to prevent transmission, diagnose and treat infections, prevent serious disease, and in many cases cure people. In addition, high risk groups inter alia health care workers still have limited access to the vaccine.

mnesty International’s annual report on the state of the world’s human rights in 2021, published in March 2022, shows that promises to “build back better” after the Covid-19 pandemic were little more than lip service. Hopes of global cooperation withered in the face of

vaccine hoarding and corporate greed.
Governments suppressed independent and critical voices, with some even using the pandemic as a pretext to shrink further the civic space. New and unresolved conflicts erupted or persisted. Those forced to flee were subjected to a litany of abuses, including pushbacks by countries in the Global North. But hopes for a better post-pandemic world were kept alive by courageous individuals, social movements and civil society organizations.

s from COVID-19.
The game comes at a critical point of the pandemic where misinformation is hindering COVID-19 vaccine acceptance and adherence to other public health measures due to fear, mistrust and doubt. By putting players in the driver’s seat, the game urges everyone to play a role in fighting harmful misinformation online, and learning and sharing the facts from trusted sources of information.
The game starts just before the pandemic begins. The player is recruited to halt the spread of SARS-COV-2, the virus that causes COVID-19, by developing vaccines and helping the human immune system fight off the virus. Based on real events, this online adventure takes the player to the frontline of science, ultimately providing lifesaving information in the palms of their hands.

Hendra virus (HeV) continues to pose a serious public health concern as spillover events occur sporadically. Terminally ill horses can exhibit a range of clinical signs including frothy nasal discharge, ataxia or forebrain signs. Early signs, if detected, can include depression, inappetence, colic o
...
r mild respiratory signs. All unvaccinated ill horses in areas where flying foxes exist, may potentially be infected with HeV, posing a significant risk to the veterinary community. Equivac® HeV vaccine has been fully registered in Australia since 2015 (and under an Australian Pesticides and Veterinary Medicines Authority special permit since 2012) for immunization of horses against HeV and is the most effective and direct solution to prevent disease transmission to horses and protect humans. No HeV vaccinated horse has tested positive for HeV infection. There is no registered vaccine to prevent, or therapeutics to treat, HeV infection in humans. Previous equine HeV outbreaks tended to cluster in winter overlapping with the foaling season (August to December), when veterinarians and horse owners have frequent close contact with horses and their bodily fluids, increasing the chance of zoonotic disease transmission. The most southerly case was detected in 2019 in the Upper Hunter region in New South Wales, which is Australia's Thoroughbred horse breeding capital. Future spillover events are predicted to move further south and inland in Queensland and New South Wales, aligning with the moving distribution of the main reservoir hosts. Here we (1) review HeV epidemiology and climate change predicted infection dynamics, (2) present a biosecurity protocol for veterinary clinics and hospitals to adopt, and (3) describe diagnostic tests currently available and those under development. Major knowledge and research gaps have been identified, including evaluation of vaccine efficacy in foals to assess current vaccination protocol recommendations.

Chikungunya virus (CHIKV) is currently one of the most relevant arboviruses to public health. It is a member of the Togaviridae family and alphavirus genus and causes an arthritogenic disease known as chikungunya fever (CHIKF). It is characterized by a multifaceted disease, which is distinguished fr
...
om other arbovirus infections by the intense and debilitating arthralgia that can last for months or years in some individuals. Despite the great social and economic burden caused by CHIKV infection, there is no vaccine or specific antiviral drugs currently available. Recent outbreaks have shown a change in the severity profile of the disease in which atypical and severe manifestation lead to hundreds of deaths, reinforcing the necessity to understand the replication and pathogenesis processes. CHIKF is a complex disease resultant from the infection of a plethora of cell types. Although there are several in vivo models for studying CHIKV infection, none of them reproduces integrally the disease signature observed in humans, which is a challenge for vaccine and drug development. Therefore, understanding the potentials and limitations of the state-of-the-art experimental models is imperative to advance in the field. In this context, the present review outlines the present knowledge on CHIKV epidemiology, replication, pathogenesis, and immunity and also brings a critical perspective on the current in vitro and in vivo state-of-the-art experimental models of CHIKF.

Dengue is the fastest spreading, mosquito-borne viral infectious disease worldwide, with remarkable morbidity and mortality. In the past decades, profound contributions have been made towards understanding its epidemiology, including disease burden and distributions, risk factors, and control and pr
...
evention practices. Dengue continues to disseminate to new areas, including high latitude regions, and a new serotype (dengue virus serotype 5) has been identified. Vaccine research has made new progress, in which the licensed yellow fever and dengue virus quadrivalent chimeric vaccine is now under further safety assessment. In disease surveillance, because of its operational simplicity, rapidity, capability, and utility as an indicator of disease severity, dengue virus NS1 antigen detection has great promotion and application value among primary health care institutions. Vector control progress has driven new breakthroughs in biotechnology, including Wolbachia-infected Aedes and genetically modified Aedes. Both Aedes variants have been used to block transmission of the dengue virus through population replacement and suppression. In the future, vector control should still be pursued as a key measure to prevent transmission, along with anti-viral drug and vaccine research.

The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re

placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).

The new WHO recommendations for rabies immunization supersede the 2010 WHO position
on pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) for rabies. These updated
recommendations are based on new evidence and directed by public health needs that are cost-,
dose- and time-sparing
...
, while assuring safety and clinical effectiveness. In addition, new guidance on
prudent use of rabies immunoglobulins (RIG) is provided.
The following sections summarize the main points of the updated WHO position as endorsed by the
Strategic Advisory Group of Experts on immunization (SAGE) at its meeting in October 20171. The full
version of the WHO position on rabies vaccines and immunoglobulins will be published in the Weekly
Epidemiological Record2 in April 2018.
Rabies prevention involves two main strategies: (i) dog vaccination to interrupt virus transmission to
humans; and (ii) human vaccination as a series of vaccine administrations before or after an exposure.
Currently, rabies vaccines made from inactivated cell cultures are extremely well tolerated and have no
contraindications.
