But the way the study was done has serious problems that make its results unreliable.<\/p>\n<p>One big problem lies in how the study uses information from\u00a0<a href=\"https:\/\/www.voicesforvaccines.org\/science\/vaccinesafety\/\" target=\"_blank\" rel=\"noopener\">VAERS<\/a>, a system where people can report health problems that happen after getting a vaccine. VAERS stands for Vaccine Adverse Event Reporting System, and it\u2019s managed by two government agencies: the CDC\u00a0and the FDA .<\/p>\n<p>However, VAERS is open to anyone, which means anyone can report a health issue after a vaccine, even if the vaccine didn\u2019t actually cause the problem. For example, if someone got a vaccine and then got a headache the next day, they could report it to VAERS, even though the headache might have had nothing to do with the shot. The VAERS website even warns that these reports don\u2019t prove the vaccine was the cause.<\/p>\n<p>Because of this, using VAERS as the main source for a scientific study can lead to false conclusions. Just because two things happen around the same time doesn\u2019t mean one caused the other.<\/p>\n<p>The\u00a0<a href=\"https:\/\/vaers.hhs.gov\/data.html\" target=\"_blank\" rel=\"noopener\">website&#8217;s<\/a>\u00a0most important warning puts the\u00a0above claims into context:\u00a0<strong>&#8220;VAERS\u00a0reports may contain information that is incomplete, inaccurate, coincidental, or unverifiable.\u00a0<\/strong>Reports to\u00a0VAERS\u00a0can also be biased. As a result, there are limitations on how\u00a0the\u00a0data can be used scientifically. Data from\u00a0VAERS\u00a0reports should always be interpreted with these limitations in mind.&#8221;<\/p>\n<p>The study also uses something called\u00a0<a href=\"https:\/\/www.aerionanalytics.com\/post\/proportional-reporting-ratio-a-simple-explanation\" target=\"_blank\" rel=\"noopener\">Proportional Reporting Ratios<\/a>\u00a0(PRRs) the wrong way. PRRs are a kind of math comparison. They look at how often a specific side effect is reported for one vaccine compared to another, based on reports sent to systems like VAERS.<\/p>\n<p>In this study, the authors calculated really high PRRs\u2014like 1120 for COVID-19 vaccines compared to flu vaccines\u2014and said this shows the COVID-19 vaccines are much more dangerous.<\/p>\n<p>But that\u2019s not how PRRs work. PRRs do not tell us how often something actually happens in real life. They only look at what\u2019s been reported, and reporting can vary a lot depending on how much attention a vaccine is getting in the news or online.<\/p>\n<p>Because of these limitations, PRRs shouldn\u2019t be used to say that one vaccine is riskier than another. It\u2019s\u00a0like measuring how scary two movies are by counting how many people posted about being scared without knowing how many actually watched each movie.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>\n<\/div><\/div>\n\n\t\t\t\t\t\t\t<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"wpex-post-cards-entry col col-1 span_1_of_1 post-14709 type-jtf_topics jtf_topic_subjects-199 jtf_topic_subjects-194 jtf_topic_subjects-218\"><div class=\"wpex-card wpex-card-template_10153\"><div class=\"wpex-card-inner\"><div class=\"vc_row wpb_row vc_row-fluid wpex-relative\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\"><div class=\"vcex-page-title vcex-module\"><h2 class=\"vcex-page-title__heading wpex-heading wpex-text-3xl\"><span class=\"vcex-page-title__text\">Were childhood vaccines properly tested?<\/span><\/h2><\/div><\/div><\/div><\/div><\/div><div class=\"vc_row wpb_row vc_row-fluid wpex-relative\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n<div class=\"vcex-post-content\">\n\t<style>.vc_custom_1708910874436{border-top-width: 1px !important;border-right-width: 1px !important;border-bottom-width: 1px !important;border-left-width: 1px !important;}<\/style>\n\t\t\t\t\t<div class=\"vcex-post-content-c wpex-clr\"><div class=\"wpb-content-wrapper\"><div class=\"vc_row wpb_row vc_row-fluid vc_custom_1708910874436 wpex-relative wpex-vc_row-has-fill wpex-vc-reset-negative-margin\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\"><div class=\"vc_row wpb_row vc_inner vc_row-fluid wpex-relative\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\"><h3 style=\"text-align: left\" class=\"vc_custom_heading vc_do_custom_heading\" >The Claim:<\/h3>\n\t<div class=\"wpb_text_column wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<p>Following last week&#8217;s Senate Oversight Committee hearing,\u00a0<a href=\"https:\/\/x.com\/ChildrensHD\/status\/1948752095869612131\" target=\"_blank\" rel=\"noopener\">anti-vaxxers<\/a>\u00a0claim\u00a0that vaccines on the childhood schedule were never tested in real science experiments using a true placebo, but instead were only compared to older vaccines or had no real comparison at all.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><div class=\"vc_row wpb_row vc_inner vc_row-fluid wpex-relative\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\"><h3 style=\"text-align: left\" class=\"vc_custom_heading vc_do_custom_heading\" >The Facts:<\/h3>\n\t<div class=\"wpb_text_column wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<p>The claim\u00a0that most childhood vaccine trials use other vaccines as controls, which are immunologically active and not inert placebos.
