By comparison the R<sub>0<\/sub> for the original SARS-CoV-2 virus is estimated to be around three.<\/p>\n<p>In 2017, the World Health Organization director <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/general\/\" data-internallinksmanager029f6b8e52c=\"3\" title=\"General\" target=\"_blank\" rel=\"noopener\">general<\/a> requested a report on the feasibility of measles and rubella eradication. One component of this report was to use transmission models to evaluate the theoretical feasibility of eradication of the two viruses given different vaccination strategies.<\/p>\n<p>The assessment was a collaboration with the WHO Strategic Advisory Group of Experts Measles and Rubella Working Group, the World Health Organization, the U.S. Centers for Disease Control and Prevention, and five modeling groups.<\/p>\n<p>Using four national disease transmission models and one sub-national model, the modeling groups projected the annual case rates for measles and rubella for two vaccination scenarios.<\/p>\n<p>Both vaccination scenarios use the two predominant vaccination <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>roaches of routine vaccination as part of childhood immunization schedules and nationwide vaccination campaigns.<\/p>\n<p>The first &#8220;business as usual&#8221; vaccination scenario continues vaccination coverage and campaigns into the future. The second &#8220;intensified investment&#8221; vaccination scenario optimally improved vaccination coverage over time. This scenario also included vaccination campaign cessation criteria\u2014a stopping point for when campaigns are no longer deemed necessary because a large enough proportion of the population has been inoculated.<br \/>\n                                            <!-- Google middle Adsense block --><\/p>\n<p>The models show that current vaccine strategies could eliminate rubella and congenital rubella syndrome in all 93 counties, but not measles. <\/p>\n<p>&#8220;The current strategy that we use, which is focused on improving routine vaccination coverage and supplementing it with nationwide vaccination campaigns until routine vaccination is high enough, that alone is not going to be sufficient to reach measles elimination. We need novel approaches,&#8221; said Winter. <\/p>\n<p>The authors evaluated two strategies that could help move a country to elimination faster and reduce the probability of measles outbreaks: One, improve how supplemental vaccine campaigns are delivered to ensure they are reaching children who are not receiving routine vaccinations.<\/p>\n<p>Two, improve vaccine coverage equity by focusing routine and supplemental vaccination on sub-regions with the lowest vaccination coverage first to get them up to par.<\/p>\n<p>&#8220;A world that is permanently free of measles and rubella would be an incredible achievement for humanity. Our work suggests that to reach this goal, we need to make vaccine coverage much more equal,&#8221; said co-author Mark Jit, professor of vaccine epidemiology at the London School of Hygiene &amp; Tropical Medicine.<\/p>\n<p>&#8220;In other words, we need to work even harder to bring measles and rubella vaccination to the most underserved people around the world.&#8221;<\/p>\n<p>The final strategy the authors present is a reconsideration of cessation criteria. Currently, most countries stop supplementing routine vaccines with vaccination campaigns once they reach elimination status, said Winter, but the models suggest that outbreaks are still likely to occur if countries rely on routine vaccines alone.<\/p>\n<p>It&#8217;s critical, Winter warns, to remain vigilant to surveil for rubella and measles cases and rapidly respond to potential outbreaks even after elimination is achieved.<\/p>\n<p>&#8220;We have a globally connected world, so there&#8217;s this constant pressure of importations of the viruses in places where it&#8217;s already eliminated,&#8221; she said. &#8220;That&#8217;s why keeping vaccination coverage high and continuing to improve surveillance for these diseases is important.&#8221;\n                                                                                                                        <\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                                                                        Measles prevention\u2014how to pull the trigger for vaccination campaigns?\n                                                                                    <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                Feasibility of measles and rubella vaccination programmes for disease elimination: a modelling study, <i>The Lancet Global Health<\/i> (2022).<\/p><\/div>\n<div class=\"d-inline-block text-medium my-4\">\n                                                Provided by<br \/>\n                                                                                                    University of Georgia<br \/>\n                                                                                                        <a rel=\"nofollow noopener\" target=\"_blank\" class=\"icon_open\" href=\"http:\/\/www.uga.edu\/\"><br \/>\n                                                        <svg>\n                                                            <use href=\"https:\/\/medx.b-cdn.net\/tmpl\/v6\/img\/svg\/sprite.svg#icon_open\" x=\"0\" y=\"0\"\/>\n                                                        <\/svg><br \/>\n                                                    <\/a><\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>\n                                                 <strong>Citation<\/strong>:<br \/>\n                                                 Current vaccine approach is not enough to eradicate measles, research shows (2022, September 13)<br \/>\n                                                 retrieved 13 September 2022<br \/>\n                                                 from https:\/\/medicalxpress.com\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2022-09-current-vaccine-approach-eradicate-measles.html<\/p>\n<p>                                            This document is subject to copyright.
