Protection from a Single Dose of HPV Vaccine A major public health impact from IARC studies of vaccine efficacy.
Background: Cervical cancer accounts for 23% of cancer incidence and 22% of cancer mortality among women in Burkina Faso. These proportions are more than 2 and 5 times higher than those of developed countries, respectively. Before 2010, cervical cancer prevention (CECAP) services in Burkina Faso wer

e limited to temporary screening campaigns.
Program Description: Between September 2010 and August 2014, program implementers collaborated with the Ministry of Health and professional associations to implement a CECAP program focused on coupling visual inspection with acetic acid (VIA) for screening with same-day cryotherapy treatment for eligible women in 14 facilities. Women with larger lesions or lesions suspect for cancer were referred for loop electrosurgical excision procedure (LEEP). The program trained providers, raised awareness through demand generation activities, and strengthened monitoring capacity.
Methods: Data on program activities, service provision, and programmatic lessons were analyzed. Three data collection tools, an individual client form, a client registry, and a monthly summary sheet, were used to track 3 key CECAP service indicators: number of women screened using VIA, proportion of women who screened VIA positive, and proportion of women screening VIA positive who received same-day cryotherapy.
Results: Over 4 years, the program screened 13,999 women for cervical cancer using VIA; 8.9% screened positive; and 65.9% received cryotherapy in a single visit. The proportion receiving cryotherapy on the same day started at a high of 82% to 93% when services were provided free of charge, but dropped to 51% when a user fee of $10 was applied to cover the cost of supplies. After reducing the fee to $4 in November 2012, the proportion increased again to 78%. Implementation challenges included difficulties tracking referred patients, stock-outs of key supplies, difficulties with machine maintenance, and prohibitive user fees. Providers were trained to independently monitor services, identify gaps, and take corrective actions.
Conclusions: Following dissemination of the results that demonstrated the acceptability and feasibility of the CECAP program, the Burkina Faso Ministry of Health included CECAP services in its minimum service delivery package in 2016. Essential components for such programs include provider training on VIA, cryotherapy, and LEEP; provider and patient demand generation; local equipment maintenance; consistent supply stocks; referral system for LEEP; non-prohibitive fees; and a monitoring data collection system.

single-dose oral vaccination was necessary to tackle an outbreak in Lusaka, Zambia, in February 2016. The emergency vaccination campaign was implemented in April 2016, targeting more than 500,000 people in Lusaka’s overcrowded township areas.
The 2016 outbreak happened when Zambia had not reported a case of cholera in four years.
To determine the effectiveness of the single-dose cholera vaccine, the researchers enrolled 66 patients with confirmed cholera and 330 people without the disease who were neighbours of the patients.
According to the study the effectiveness of the single dose vaccination was about 90 per cent.

Cryptococcal disease is one of the most common opportunistic infections among people living with advanced HIV disease and is a major contributor to severe illness, morbidity, and mortality, particularly in sub-Saharan Africa.
These guidelines update the recommendations that were first released i
...
n 2018 on diagnosing, preventing, and managing cryptococcal disease. In response to important new evidence that became available in 2021, these new guidelines strongly recommend a single high dose of liposomal amphotericin B as part of the preferred induction regimen for the treatment of cryptococcal meningitis in people living with HIV. This simplified regimen - a single high dose of liposomal amphotericin B paired with other standard medicines (flucytosine and fluconazole) - is as effective as the previous WHO standard of care, with the benefits of lower toxicity and fewer monitoring demands.
The objective of these guidelines is to provide updated, evidence-informed recommendations for treating adults, adolescents and children living with HIV who have cryptococcal disease. These guidelines are aimed at HIV programme managers, policymakers, national treatment advisory boards, implementing partners and health-care professionals providing care for people living with HIV in resource-limited settings with a high burden of cryptococcal disease.

This publication describes the first WHO public-benefit Target Product Profiles (TPPs) for snakebite antivenoms. It focuses on antivenoms for treatment of snakebite envenoming in sub-Saharan Africa. Four TPPs are described in the document:

that are intended for widespread utility throughout sub-Saharan Africa for treatment of envenoming irrespective of the species of snake causing a bite. Monovalent antivenoms for specific use cases: for products for a single species (or genus) of snake (e.g., boomslangs or carpet viper antivenoms).
Syndromic Pan-African polyvalent antivenoms for neurotoxic envenoming: products that are intended for treatment of envenoming by species whose venoms are neurotoxic. Syndromic Pan-African polyvalent antivenoms for non-neurotoxic envenoming: products for snakebite envenoming where the effects are largely haemorrhagic, necrotic or procoagulant.
