ABSTRACT

OBJECTIVE: The immunisation programme in Zambia remains one of the most effective public health programmes. Its financial sustainability is, however, uncertain. Using administrative data on immunisation coverage rate, vaccine utilisation, the number of health facilities and human resources, expenditure on health promotion, and the provision of outreach services from 24 districts, we used Data Envelopment Analysis to determine the level of technical efficiency in the provision of immunisation services. Based on our calculated levels of technical efficiency, we determined the available fiscal space for immunisation. RESULTS: Out of the 24 districts in our sample, 9 (38%) were technically inefficient in the provision of immunisation services. The average efficiency score, however, was quite high, at 0.92 (CRS technology) and 0.95 (VRS technology). Based on the calculated level of technical efficiency, we estimated that an improvement in technical efficiency can save enough vaccine doses to supply between 5 and 14 additional districts. The challenge, however, lies in identifying and correcting for the sources of technical inefficiency.

ABSTRACT

Uninterrupted availability of vaccines requires a robust vaccine supply chain and logistics system (VSCLS). With special focus on remote and underserved settings, we assessed the reach and bottlenecks of the Ethiopian VSCLS after the initiation of the last mile transition. We explored the perspectives of key stakeholders using a qualitative phenomenological study. More than 300 in-depth interviews and 22 focus group discussions were conducted. The study was sequentially implemented over two phases to understand the bottlenecks at national and regional (Phase I) and lower (Phase II) levels. After the transition, the Ethiopian Pharmaceutical Supply Service started supplying vaccines directly to health facilities, bypassing intermediaries. The transition reduced supply hiccups and enabled the health sector to focus on its core activities. However, in remote areas, achievements were modest, and health facilities have been receiving supplies indirectly through district health offices. By design, health posts collect vaccines from health centers, causing demotivation of health extension workers and frequent closure of health posts. Challenges of the VSCLS include artificial shortage due to ill forecasting and failure to request needs on time, lack of functional refrigerators secondary to scarcity of skilled technicians and spare parts, and absence of dependable backup power at health centers. Vaccine wastages owing to poor forecasts, negligence, and cold chain problems are common. The VSCLS has not yet sustainably embraced digital logistics solutions. The system is overstrained by frequent outbreak responses and introduction of new vaccines. We concluded that the transition has improved the VSCLS, but the reach remains suboptimal in remote areas.

ABSTRACT

Despite having emerged from pandemic status, the incidence of COVID-19 episodes has recently increased in Spain, including pediatric cases and admissions to Intensive Care Units. Several recombinant variants are circulating among us, particularly XBB arising from two Omicron BA.2 sublineages with mutations in the genes encoding the spicule proteins that could increase binding to the ACE2 receptor and be more prone to immune escape. Faced with these, 3 pharmaceutical companies have developed vaccines adapted to the XBB.1.5 sublineage that are already available for administration in our setting with risks that should not be different from those of previous mRNA vaccines and with clearly favorable benefit/risk ratios. They should be applied to patients with potential for poor COVID-19 evolution and to collectives that have a particular relationship of proximity with them. Their application should be understood not only from a perspective of individual convenience but also from that of collective responsibility. The most convenient seems to be a simultaneous immunization of COVID-19 and influenza in our environment. In the therapeutic aspect, there is little to expect right now from antisera, but the already known antiviral drugs are still available and indicated, although their efficacy will have to be reevaluated due to their impact on populations that are mostly immunized and with a better prognosis than in the past. In our opinion, it is necessary to continue to make a reasonable and timely use of masks and other non-pharmacological means of protection. (AU)


Pese a haber salido de la situación de pandemia, la incidencia de episodios de COVID-19 ha aumentado recientemente en España, incluidos los casos pediátricos y los ingresos en Unidades de Cuidados Intensivos. Circulan entre nosotros diversas variantes recombinantes, particularmente la XBB surgidas de dos sublinajes Omicron BA.2 con mutaciones en los genes que codifican las proteínas de la espícula y que pudieran aumentar la unión al receptor ACE2 y ser más propensas al escape inmune. Frente a ellas, 3 empresas farmacéuticas han elaborado vacunas adaptadas al sublinaje XBB.1.5 que ya se encuentran disponibles para su administración en nuestro medio con riesgos que no deben ser diferentes a los de las vacunas mRNA previas y con relaciones beneficio/riesgos claramente favorables. Deben aplicarse a pacientes con potencial de mala evolución de COVID-19 y a los colectivos que tienen una particular relación de proximidad con ellos. Su aplicación debe ser entendida no sólo desde una perspectiva de conveniencia individual sino desde la de la responsabilidad colectiva. Lo más conveniente parece hacer una inmunización simultánea de COVID-19 y gripe en nuestro medio. En el aspecto terapéutico hay poco que esperar ahora mismo de los antisueros pero siguen estando disponibles e indicados los fármacos antivirales ya conocidos aunque su eficacia tendrá que reevaluarse por su impacto en poblaciones mayoritariamente inmunizadas y con pronóstico mejor que las de tiempos pasados. A nuestro juicio, es necesario seguir haciendo un uso razonable y puntual de mascarillas y otros medios no farmacológicos de protección. (AU)

ABSTRACT

Fasciola spp., Opisthorchis spp. and Clonorchis sinensis are common liver flukes that can cause a variety of diseases, mainly cholangiocarcinoma induced by clonorchiasis and liver damage and associated pathology induced by fascioliasis. Because these trematodes are parasites of humans and domestic animals, they have greatly affected the economy of agricultural industries and public health worldwide. Due to the emergence of drug resistance and the living habits of flukes, among other reasons, a possibility of reinfection remains even when antiparasitic drugs are used. Therefore, developing a safe, efficient and cost-effective vaccine against trematodes is an important goal. Here, we briefly describe the progress in the development of vaccines against liver flukes. Related innovations may provide effective protection against these helminths and the diseases that they cause.

ABSTRACT

As the fight against the coronavirus disease 2019 (COVID-19) pandemic continues, the necessity for wide-scale, global vaccine rollout to reduce the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and slow its mutation rate remains unassailable. The COVID-19 Vaccines Global Access (COVAX) initiative's campaign involves a proportional framework to finance and distribute SARS-CoV-2 vaccines in low- and middle-income countries. However, the COVAX framework has critical limitations, including limited funding and the failure to account for the special epidemic risks and needs of its participating nations, as recommended by the World Health Organization's Strategic Advisory Group of Experts on Immunization framework. These drawbacks disproportionately impact Africa, where many nations rely on COVAX as their main source of vaccines. The current plan to vaccinate only up to 20% of participating nations' populations is short-sighted from both epidemiologic and moral perspectives. COVAX must commit to vaccinating all of Africa and its initiative must be modified to account for the health and economic infrastructures in these countries. Lessons learned from successful vaccination campaigns, including the West African Ebola outbreak, have shown that vaccinating all of Africa is possible and feasible, and that infrastructure and human resources can support mass vaccination. To halt this global pandemic, global responsibility must be accepted to finance and equitably distribute SARS-CoV-2 vaccines to African nations. We urge COVAX to act swiftly to prevent Africa from becoming the new face of a persisting pandemic.
