“…Such instances include vaccinations for influenza A H1N1,76 tetanus,77–79 human papilloma virus,80 hepatitis B81 82 and oral cholera immunisation 83. Many of these incidents appear to have started with index cases that were genuine vaccine reactions, which generated anxiety and facilitated the spread of symptoms among otherwise healthy observers.…”

Expectation of treatment side effects is consistently linked with those symptoms being realised. Patient expectations, including those generated by the informed consent process, can have a large influence on the side effects that patients feel after starting a new medical treatment. Such symptoms may be the result of the nocebo effect, whereby the expectation of side effects leads to them being experienced. Side effects may also be due to the misattribution of pre-existing or unrelated symptoms to the new medication. Medical professionals' own negative beliefs about a treatment, especially generic drugs, may further enhance patients' expectations of adverse effects. The news media may also influence expectations, particularly when media attention is directed towards a health or medication scare. This field of research has ethical and clinical implications for both medical professionals and the news media with respect to the level and type of information about treatment side effects that is provided to patients or members of the public.

“…Furthermore, the vaccine has also been used as a preventive measure during cholera outbreaks [Khiem et al 2003;Anh et al 2011]. During the 2007-2008 cholera outbreaks in Vietnam, the vaccine was given to residents of two districts in Hanoi.…”

Cholera is still a major global health problem, affecting mainly people living in unsanitary conditions and who are at risk for outbreaks of cholera. During the past decade, outbreaks are increasingly reported from more countries. From the early killed oral cholera vaccine, rapid improvements in vaccine development occurred as a result of a better understanding of the epidemiology of the disease, pathogenesis of cholera infection and immunity. The newer-generation oral killed cholera vaccines have been shown to be safe and effective in field trials conducted in cholera endemic areas. Likewise, they have been shown to be protective when used during outbreak settings. Aside from providing direct protection to vaccinated individuals, recent studies have demonstrated that these killed oral vaccines also confer indirect protection through herd immunity. Although new-generation oral cholera vaccines should not be considered in isolation from other preventive approaches in countries where they are most needed, especially improved water quality and sanitation, these vaccines serve as immediately available public health tools for preventing further morbidity and mortality from cholera. However, despite its availability for more than two decades, use of these vaccines has not been optimized. Although there are limitations of the currently available oral cholera vaccines, recent data show that the vaccines are safe, feasible to use even in difficult circumstances and able to provide protection in various settings. Clear identification of the areas and target population groups who will benefit from the use of the cholera vaccines will be required and strategies to facilitate accessibility and usage of these vaccines in these areas and population groups will need to be developed.

“…All data collected was associated with preemptive strategic campaigns due to displaced populations to refugee camps post natural or manmade disasters. The country of Vietnam is the most extensive user of preemptive OCV vaccination campaigns and had administered over 20 million doses to high risk populations especially following floods within the country (Anh et al, 2011;DeRoeck & Jodar, 2004;Khiem et al, 2003). One instance of reactive vaccination campaign was in Hanoi in 2008 in which "an estimated 80% of the 370 000 persons eligible for vaccination received ≥1 dose.…”

Cholera is a significant post disaster risk to an already affected population. As a first responder to these disasters, the Marine Air Ground Task Force (MAGTF) must consider an epidemic cholera outbreak as a threat to mitigate and be considered in the planning process for Humanitarian Aid/Disaster Relief (HA/DR) scenarios. This project considers these factors based on former HA/DR events as well as an inventory management model which determines optimized stock pile of vaccinations necessary in a given year in order to reduce the number of lives lost to cholera.
