The article "Effectiveness of one dose of oral cholera vaccine in response to an outbreak: a case-cohort study" investigates whether a single dose of the Shanchol oral cholera vaccine can provide effective protection during an outbreak. Conducted i...n Juba, South Sudan, in 2015, the study involved a case-cohort approach, analyzing vaccination status and disease outcomes.
Findings showed that a single dose was 80.2% effective in preventing medically attended cholera cases, increasing to 87.3% after adjustments for confounding factors. These results suggest that a single-dose strategy can be an effective emergency response, particularly in settings with limited vaccine supply and high mobility of affected populations. The study supports using a single-dose approach during outbreaks when a two-dose regimen is logistically challenging.

Protection from a Single Dose of HPV Vaccine A major public health impact from IARC studies of vaccine efficacy.
This policy brief draws from the latest evidence on the impact of vaccination program start date and vaccine rollout rates on health benefits. The objective is to support policymakers on decisions to procure COVID-19 vaccines and roll out vaccination programmes in countries, especially those
where ...large proportions of the population remain unvaccinated.

This guidance document provides basic principles for a spokesperson of any health authority on how to respond to vocal vaccine deniers. The suggestions are based on psychological research on persuasion, on research in public health, communication studies and on WHO risk communication guidelines.
The technical note by the Global Task Force on Cholera Control (GTFCC) discusses the use of Oral Cholera Vaccines (OCVs) for international workers and travelers in cholera-affected areas. It reviews the effectiveness of WHO-prequalified vaccines (Dukoral®, Shanchol™, and Euvichol®), emphasizing ...their role in preventing infection and reducing transmission risks.
The document highlights concerns about travelers contracting cholera in endemic regions and potentially spreading the disease upon returning home. While the overall risk is considered low, certain groups, such as humanitarian workers and travelers to high-risk areas like South Asia, face a higher exposure.
Recommendations include vaccination for emergency and relief workers who may come into direct contact with cholera patients or contaminated environments. However, routine vaccination for general travelers is not widely recommended. The note also calls for better surveillance and studies to assess the potential of vaccines in preventing international transmission.

The immunization program has been going well until a rumor begins that one child in a community far from the capital has become sick after receiving a vaccine. The rumor is becoming stronger every day and is picking up coverage on local radio.
Concerned that the rumor might make caregivers concer...ned about bringing their children for vaccination, a few frontline workers (FLWs) go to the house of the children who fell sick. They find out from the child's mother that she never thought her son was sick due to the vaccination he received. The mother agrees to speak to other caregivers during a community gathering to explain that her son's illness was not caused by his vaccination. She also responds to a few questions to reassure other caregivers about the safety and advantages of immunization.
