Since there is no uniform system for counting cases, this is most likely a gross underestimate.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">In October 2022, the organization that manages the global emergency cholera vaccine stockpile made an <a class=\"css-yywogo\" href=\"https:\/\/www.nytimes.com\/2022\/10\/31\/health\/cholera-outbreaks-vaccine.html\" title=\"\">unprecedented recommendation<\/a> that people receive only one dose of the vaccine instead of two in an effort to stretch the supply. A single dose of the cholera vaccine provides between six months and two years of immunity, while the full regimen of two doses delivered a month apart gives adults roughly four years of protection.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Last year, countries sent requests for 76 million doses of the vaccine for single-dose \u201creactive campaigns\u201d \u2014 efforts to vaccinate people in places with active outbreaks.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">There were only 38 million doses in the stockpile, so only half the requests were filled, and those were with only a single dose. No vaccines were left for preventive campaigns that would ideally be carried out in places such as Gaza, where all of the conditions for large outbreaks exist, or in places where cholera is endemic.<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"\/><\/div>\n<div>\n<div class=\"css-53u6y8\">\n<p class=\"css-at9mc1 evys1bk0\">The race to make more cholera vaccine illustrates all of the reasons it\u2019s so hard to respond to epidemics even with the participation of committed drug makers who are not scared off by the slim profit margins in an immunization that\u2019s mostly for poor people.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Cholera can cause death by dehydration in as little as a single day as the body tries to expel virulent bacteria in streams of vomit and watery diarrhea. The disease is spread through unclean drinking water. The current outbreaks are being driven by the spread of conflict and climate disasters that force people into crowded living situations without adequate sanitation systems. In recent months, there have been outbreaks in 17 countries, including Afghanistan, Zambia and Syria.<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"\/><\/div>\n<div>\n<div class=\"css-53u6y8\">\n<p class=\"css-at9mc1 evys1bk0\">Yet demand has only grown since then.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">The South Korean company EuBiologics is currently the sole company worldwide that makes the cholera vaccine. The company had been aware for some time that there would be pressure on the supply of the vaccine because the only other firm that made it, an Indian subsidiary of the drug company Sanofi, had announced in 2018 that it would end production of the vaccine, which it did in 2023.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">To cover the gap in vaccine production, Rachel Park, the director of international business at EuBiologics, said the company decided to try to simplify its vaccine formula, streamlining steps and ingredients so it could make more doses faster.<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"\/><\/div>\n<div>\n<div class=\"css-53u6y8\">\n<p class=\"css-at9mc1 evys1bk0\">The company was then making more of the bulk drug product than it could put into tubes quickly, so it contracted a second Korean firm to assist.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">EuBiologics also invested in construction of a second manufacturing site that would double the amount of the vaccine the company could make. The company has taken the lengthy and expensive steps of having both the simplified vaccine and its new facility approved by the World Health Organization in a process called prequalification, which means that countries will not have to administer their own regulatory assessments. When the new plant starts producing the company will be able to make up to 46 million doses a year.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">\u201cEuBiologics is really the unsung hero of the story,\u201d said Dr. Julia Lynch, the director of the cholera vaccine program for the International Vaccine Institute, a United Nations-backed organization based in Seoul. \u201cThey are doing everything they can to get volumes up as fast as possible.\u201d<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Together, these steps should increase production to a total of about 46 million doses this year, and to about 90 million doses in 2025 and onward, Ms. Park said. But that will still most likely be significantly less than what the world requires.<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"\/><\/div>\n<div>\n<div class=\"css-53u6y8\">\n<p class=\"css-at9mc1 evys1bk0\">\u201cDoses are being allotted before they are even produced,\u201d said Dr. Daniela Garone, the international medical coordinator for Doctors Without Borders who sits on the committee that decides which countries will receive doses, and how many. \u201cWe weren\u2019t expecting it to be better this year, but we didn\u2019t think it would be this much worse.\u201d<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"\/><\/div>\n<div>\n<div class=\"css-53u6y8\">\n<p class=\"css-at9mc1 evys1bk0\">There is some more hope on the distant horizon: Three more drug companies have cholera vaccines in their pipeline. The International Vaccine Institute has licensed its vaccine<span class=\"css-8l6xbc evw5hdy0\">  <\/span>to Biological E, an Indian firm, and is sharing the formula and equipment for making it.. If all goes well, that vaccine could come to market by the end of 2026 because Biological E is a large company that already makes many products prequalified by the W.H.O.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">In South Africa, a company called Biovac will soon start clinical trials on what eventually could be the first vaccine ever produced from start to finish in sub-Saharan Africa. Biovac hopes to conclude the trials by 2027. After that, it will most likely take at least a year for the vaccine to obtain W.H.O. prequalification, said Dr. Morena Makhoana, the chief executive of Biovac.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Bharat Biotech, another big Indian company with large production capacity, is working on its own oral cholera vaccine. It could bring its vaccine to market by the end of 2025.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">To spur companies to invest in producing cholera vaccines, Gavi, the international organization that supplies immunizations to low- and middle-income countries, has indicated the possibility of advance market commitments \u2014 the promise of future orders that would encourage drugmakers to invest in producing the cholera vaccine. Gavi pays EuBiologics $1.53 per dose for the vaccine.<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"\/><\/div>\n<div>\n<div class=\"css-53u6y8\">\n<p class=\"css-at9mc1 evys1bk0\">Bharat and Biological E both plan to produce about 15 million doses per year initially, Dr. Lynch said \u2014 \u201cmodest quantities\u201d by the standards of these huge Indian companies that could make more if the market continues to grow.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">The potential demand is difficult to predict, she said. \u201cThat\u2019s really the question: Is what the world is going through right now a kind of phenomena of a few years triggered by something?\u201d Dr. Lynch said. \u201cOr is this a new normal? Is this a new kind of set point?\u201d<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"\/><\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/www.nytimes.com\/2024\/04\/11\/health\/cholera-vaccine-shortage.html\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Doses of cholera vaccine are being given to patients as fast as they are produced and the global stockpile has run completely dry, as deadly outbreaks of the disease continue to spread.
