It found that while both vaccines provided some degree of protection against both variants in the first 90 days, effectiveness waned after this, especially against the omicron variant. In particular, it found that both vaccines had negative effectiveness against the omicron variant after 90 days, a detail the Rogue Review bases its claim on.<\/p>\n<p>The study notes, however, that these findings are \u201carguably\u201d indicative of&nbsp; \u201cdifferent behaviour and\/or exposure patterns\u201d in the vaccinated and unvaccinated populations and that this is possibly \u201ccausing underestimation of the VE [vaccine effectiveness].\u201d At no point in the study do the authors state or suggest the data indicates the vaccinated are more likely to be infected with the virus than the unvaccinated.<\/p>\n<p><a href=\"https:\/\/www.lshtm.ac.uk\/aboutus\/people\/hansen.christian\" target=\"_blank\" rel=\"noopener noreferrer\">Dr. Christian Holm Hansen<\/a>, one of the study\u2019s co-authors and an assistant professor of medical statistics and epidemiology at the London School of Hygiene and Tropical Medicine, told Check Your Fact in an email that the viral post was misrepresenting the study\u2019s data and explained that there were \u201ca number of reasons why the VE estimate might be negative.\u201d<\/p>\n<p>\u201cIn many places including Denmark, vaccinated individuals are tested more frequently than unvaccinated individuals,\u201d said Hansen. \u201cThis causes the incidence rate to be higher in the vaccinated population and resultantly a negative VE estimate.\u201d<strong><a href=\"https:\/\/checkyourfact.com\/2020\/03\/25\/fact-check-swine-flu-kill-18000-americans\/\" target=\"_blank\" rel=\"noopener noreferrer\">(RELATED: Did The 2009 Swine Flu Pandemic Kill 18,000 Americans?)<\/a><\/strong><\/p>\n<p>Hansen also noted that when officials in Denmark first identified the omicron variant, they traced many of the first instances of it in the country to international travelers and their social and professional groups \u2013 people who were largely vaccinated. He explained this may have skewed the data. \u201cWe expect therefore that there was an overrepresentation of vaccinated people among the first generations of Omicron cases identified in Denmark, not because the vaccines weren\u2019t protective, but because the variant hadn\u2019t spread far enough into the general population, including into the unvaccinated population, to make for comparable infection rates,\u201d said Hansen.<\/p>\n<p>He further explained that the estimation of effectiveness relied on the behavior of vaccinated and unvaccinated individuals, stating that discrepancies in risk behavior would lead to an underestimated number. He concluded his email by saying, \u201cthe vaccines\u2019 protective effect may be low against infection with Omicron after 4 months, but it is most unlikely to be negative!\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>An image\u00a0shared on Instagram claims a Yale University study found that people who are vaccinated against COVID-19 are more likely to be infected with the virus than those who are &#8230;<\/p>\n","protected":false},"author":68,"featured_media":2315279,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_mo_disable_npp":"","fifu_image_url":"","fifu_image_alt":"","footnotes":""},"categories":[],"tags":[],"class_list":["post-1197784","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry"],"_links":{"self":[{"href":"https:\/\/www.conservativenewsdaily.net\/breaking-news\/wp-json\/wp\/v2\/posts\/1197784","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.conservativenewsdaily.net\/breaking-news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.conservativenewsdaily.net\/breaking-news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.conservativenewsdaily.net\/breaking-news\/wp-json\/wp\/v2\/users\/68"}],"replies":[{"embeddable":true,"href":"https:\/\/www.conservativenewsdaily.net\/breaking-news\/wp-json\/wp\/v2\/comments?post=1197784"}],"version-history":[{"count":0,"href":"https:\/\/www.conservativenewsdaily.net\/breaking-news\/wp-json\/wp\/v2\/posts\/1197784\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.conservativenewsdaily.net\/breaking-news\/wp-json\/wp\/v2\/media\/2315279"}],"wp:attachment":[{"href":"https:\/\/www.conservativenewsdaily.net\/breaking-news\/wp-json\/wp\/v2\/media?parent=1197784"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.conservativenewsdaily.net\/breaking-news\/wp-json\/wp\/v2\/categories?post=1197784"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.conservativenewsdaily.net\/breaking-news\/wp-json\/wp\/v2\/tags?post=1197784"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
