Doing so would leave them unprotected against a serious disease, even though we know they could get hurt.<\/p>\n<p>A good example is the pneumococcal vaccine.\u00a0<a href=\"https:\/\/www.cdc.gov\/acip\/grade\/PCV13.html\" target=\"_blank\" rel=\"noopener\">Prevnar-13<\/a>\u00a0was tested against Prevnar-7, an older vaccine that already\u00a0<a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC3733065\/\" target=\"_blank\" rel=\"noopener\">worked<\/a>. Using saline instead would have meant leaving children unprotected against dangerous bacterial infections. That would have put children at real risk of serious illness or death.<\/p>\n<p>In these cases, scientists compare the new vaccine to an older one to make sure it works as well or better, while still keeping people safe.<\/p>\n<p>Why not just use saline placebos?\u00a0The answer is simple: babies are vulnerable. When scientists already know a vaccine prevents serious disease, they do not want to leave some babies unprotected just to satisfy a study design.<\/p>\n<p>Instead, researchers:<\/p>\n<ul>\n<li>Compare new vaccines to trusted older ones<\/li>\n<li>Track safety through long-term\u00a0<a href=\"https:\/\/publichealth.jhu.edu\/2025\/how-the-us-ensures-vaccine-safety\" target=\"_blank\" rel=\"noopener\">studies<\/a><\/li>\n<li><a href=\"https:\/\/www.ema.europa.eu\/en\/about-us\/what-we-do\/crisis-preparedness-management\/vaccine-monitoring-platform\" target=\"_blank\" rel=\"noopener\">Monitor<\/a>\u00a0millions of real-world doses after approval<\/li>\n<\/ul>\n<p>Vaccines are tested for many years.

Scientists looked carefully for both short-term and long-term side effects.<\/p>\n<p>Some also claim that the hepatitis B vaccines were only tested for five days. They came up with this idea\u00a0from reading vaccine package inserts, which are legal documents, not full research reports. The \u201cfive days\u201d only referred to watching for mild problems at the injection site, like a sore leg. Serious health problems were tracked for months, and other symptoms like fever were tracked for weeks.<\/p>\n<p><a href=\"https:\/\/www.voicesforvaccines.org\/answering-key-questions-on-hepatitis-b-birth-dose-at-a-critical-time\/\" target=\"_blank\" rel=\"noopener\">Hepatitis B<\/a>\u00a0can cause lifelong infection, liver damage, and liver cancer. The younger someone is when infected, the more likely it is to become chronic. There is no cure, but the vaccine can prevent it. That is why protecting infants early is so important.<\/p>\n<p>Science does not rely on rumors or shortcuts. It relies on careful testing, ethical rules, and ongoing safety monitoring.<\/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-15479 type-jtf_topics jtf_topic_subjects-195 jtf_topic_subjects-199 jtf_topic_subjects-191 jtf_topic_subjects-203 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\">Was it sanitation or vaccination?<\/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>In 2025, the\u00a0<strong>\u201csanitation, not vaccines\u201d trope<\/strong>\u00a0spread widely.\u00a0It claims that clean water, nutrition, and hygiene \u2014 not vaccines \u2014 are what reduced deadly diseases.

They are especially important for diseases spread through food and water, like diarrhea, which still kills over 500,000 children under age five each year worldwide.<\/p>\n<p>Sanitation helped make people less likely to die once they were sick. Better food, cleaner hospitals, and improved care meant stronger bodies and better recovery. But many dangerous diseases spread through the air, not through dirty water. For these diseases, sanitation does very little to stop infection.<\/p>\n<p>This is where many\u00a0<a href=\"https:\/\/ourworldindata.org\/vaccination\" target=\"_blank\" rel=\"noopener\">charts<\/a>\u00a0are confusing. They often show death rates, not how many people actually got sick. Deaths went down over time because care improved, even while large numbers of people were still being infected. Before vaccines, nearly every child got measles, polio caused tens of thousands of cases each year in the U.S., and smallpox kept causing outbreaks around the world.<\/p>\n<p>When vaccines were introduced,\u00a0<a href=\"https:\/\/www.redcross.org.uk\/stories\/our-movement\/our-history\/vaccination-a-history-of-saving-lives\" target=\"_blank\" rel=\"noopener\">case numbers dropped<\/a>\u00a0sharply, not just deaths. Looking only at death charts hides this difference and makes it seem like vaccines were not needed, when they were actually the turning point.<\/p>\n<p>Measles is one of the most contagious diseases ever known. It spreads through the air and can stay in a room for up to two hours after a sick person has left. If one person has measles, an unvaccinated person has a 90% chance of getting sick.<\/p>\n<p>Before the\u00a0<a href=\"https:\/\/www.voicesforvaccines.org\/vaccine-information\/mmr\/\" target=\"_blank\" rel=\"noopener\">measles<\/a>\u00a0vaccine in 1964:<\/p>\n<ul>\n<li>Nearly all children got measles by age 15<\/li>\n<li>500\u2013600 children died each year in the United States<\/li>\n<\/ul>\n<p>Two doses of the MMR vaccine prevent about 98% of measles cases. Vaccination has prevented tens of millions of deaths worldwide. Good nutrition and vitamin A can help someone recover, but they do not stop measles from spreading.<\/p>\n<p><a href=\"https:\/\/www.voicesforvaccines.org\/vaccine-information\/polio\/\" target=\"_blank\" rel=\"noopener\">Polio<\/a>\u00a0is caused by a virus, not chemicals like DDT. Scientists have isolated the poliovirus many times and shown that it causes paralysis.<\/p>\n<p>Before vaccines:<\/p>\n<ul>\n<li>The U.S. had about 57,000 polio cases in 1952<\/li>\n<li>Over 21,000 of those cases caused paralysis<\/li>\n<\/ul>\n<p>Polio spreads through tiny amounts of fecal matter (poop), often without anyone knowing. Before modern sanitation, most children were exposed to polio as babies, when they were protected by antibodies from their mothers. They usually had mild illness and became immune.<\/p>\n<p>When sanitation improved in the early 1900s, children were exposed later in life, after that protection was gone. This led to\u00a0<a href=\"https:\/\/www.aip.org\/inside-science\/complicated-twists-in-fight-to-eradicate-polio#:~:text=Scientists%20noted%20that%20up%20until,They%20became%20immune.\" target=\"_blank\" rel=\"noopener\">larger and more severe<\/a>\u00a0outbreaks, even though overall health improved. Sanitation changed who got polio, but it did not stop the virus. Vaccination did.<\/p>\n<p>We still vaccinate for polio today because the virus still exists in parts of the world and can return through travel, as shown by the U.S. polio case in 2022.<\/p>\n<p>Smallpox spread through the air, not dirty water. Even as sanitation improved, smallpox continued to cause deadly outbreaks for centuries. Smallpox was\u00a0<a href=\"https:\/\/www.who.int\/news-room\/spotlight\/history-of-vaccination\/history-of-smallpox-vaccination\/\" target=\"_blank\" rel=\"noopener\">eradicated<\/a>\u00a0through a global vaccination campaign. Since eradication in 1980, there have been zero natural cases anywhere in the world. No sanitation effort has ever achieved this for an airborne disease.<\/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-15480 type-jtf_topics jtf_topic_subjects-202 jtf_topic_subjects-189 jtf_topic_subjects-188 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\">Are we still worried about cancer and COVID vaccines?<\/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>One of the most consistent rumors of the last five years is that COVID vaccination causes <a href=\"https:\/\/www.voicesforvaccines.org\/jtf_topic_subjects\/cancer\/\">cancer<\/a>.<\/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>After years of careful monitoring, there is still\u00a0<a href=\"https:\/\/fullfact.org\/health\/aseem-malhotra-reform-conference-vaccines\/\" target=\"_blank\" rel=\"noopener\">no evidence<\/a>\u00a0that COVID\u00a0vaccines cause cancer. No studies show a rise in cancer linked to vaccination, and there is no realistic biological process that explains how vaccines could cause cancer. These claims rely on misunderstandings of biology, poor-quality data, or fear-based language rather than solid evidence.<\/p>\n<p>One variation of this claim is\u00a0something they call \u201cturbo cancer.\u201d These claims sound frightening, but they are not supported by science. When scientists carefully study how vaccines work and examine real-world data, they find no evidence that vaccines cause cancer or change a person\u2019s DNA.<\/p>\n<p>The idea of \u201cturbo cancer\u201d is not a real medical term. Doctors and scientists do not use it, and it does not describe any known disease. Cancer does not appear suddenly. Even the strongest cancer-causing substances, called carcinogens, usually take\u00a0<a href=\"https:\/\/ascopost.com\/issues\/may-25-2021\/chernobyl-at-35-years-an-oncologist-s-perspective\/\" target=\"_blank\" rel=\"noopener\">many years<\/a>\u00a0to cause cancer because damage builds up slowly in cells over time. If vaccines caused cancer, scientists would expect to see increases years later, not right after vaccination.<\/p>\n<p>Researchers also study health patterns in very large groups of people. These studies look for real-world trends across millions of individuals. When scientists examine this data, they\u00a0<a href=\"https:\/\/www.aap.com.au\/factcheck\/no-german-study-did-not-find-covid-vaccines-increase-cancer-risk-for-kids\/\" target=\"_blank\" rel=\"noopener\">do not<\/a>\u00a0see an increase in cancer linked to COVID\u00a0vaccines. Some people point to rising cancer rates in younger adults, but this trend began in the early\u00a0<a href=\"https:\/\/bmjoncology.bmj.com\/content\/2\/1\/e000049\" target=\"_blank\" rel=\"noopener\">1990s<\/a>, long before COVID vaccines existed.<\/p>\n<p>Despite this, some critics claim vaccines contain dangerous DNA that can damage our genes. These claims often come from\u00a0<a href=\"https:\/\/osf.io\/preprints\/osf\/mjc97_v1\" target=\"_blank\" rel=\"noopener\">studies<\/a>\u00a0that have serious problems. In some cases, the researchers tested expired vaccines or vaccines that were not stored correctly. This matters because mRNA is\u00a0<a href=\"https:\/\/www.nebraskamed.com\/COVID\/where-mrna-vaccines-and-spike-proteins-go\" target=\"_blank\" rel=\"noopener\">fragile<\/a>\u00a0and breaks down quickly, especially with heat or time, while DNA is much more stable. When mRNA breaks apart, the tiny leftover DNA can look larger by comparison, even though the amount has not changed. This can make test results misleading.<\/p>\n<p>The DNA being discussed is not harmful or active in the body. It comes from a promoter gene, which works like a light switch used during vaccine production to tell cells when to start making RNA. Promoter genes help manufacture the vaccine but are not meant to be ingredients. Almost all of this DNA is removed before the vaccine is finished, and any tiny traces left behind are not dangerous.<\/p>\n<p>More importantly, vaccines\u00a0<a href=\"https:\/\/youtu.be\/IGKg9rj9W1s?si=0fFM3b1SIszpRR85\" target=\"_blank\" rel=\"noopener\">cannot change<\/a>\u00a0your DNA. Vaccine mRNA stays in the cytoplasm, the outer area of the cell where proteins are made. Our DNA is kept safely inside the nucleus, which has a strong protective barrier. Vaccine material does not have the signal needed to enter the nucleus. Even if it could, it would still need a special helper protein, called an enzyme, to attach to DNA. One such enzyme, integrase, acts like glue.\u00a0But the vaccines do not contain integrase, so they cannot get to your DNA.<\/p>\n<p>There is also a basic biology reason these claims do not work. Human DNA is double-stranded, like a zipper with two matching sides, while mRNA is single-stranded, like a loose string. Because they are built differently, mRNA\u00a0<a href=\"https:\/\/www.iflscience.com\/mrna-cant-change-the-dna-in-our-cells-heres-why-71734\" target=\"_blank\" rel=\"noopener\">cannot merge with or rewrite<\/a>\u00a0DNA. This is why mRNA vaccines are not gene therapy. They give temporary instructions to make a protein and then break down and leave the body.<\/p>\n<p>Science does not depend on one study or one voice. It works by testing ideas, repeating experiments, and having many experts review the results. When scientists around the world examine the same question and reach the same conclusion, this is called scientific consensus. The scientific consensus is clear: COVID\u00a0vaccines do not cause cancer.<\/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><\/div><\/div>[\/vc_column][\/vc_row]\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Clearing up the facts on vaccine safety, placebo trials, and cancer myths with science-backed answers to the latest viral claims and conspiracy theories.<\/p>\n","protected":false},"template":"","jtf_topic_subjects":[],"class_list":["post-15477","just-the-facts","type-just-the-facts","status-publish","hentry","entry","no-media"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.voicesforvaccines.org\/es\/wp-json\/wp\/v2\/just-the-facts\/15477","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.voicesforvaccines.org\/es\/wp-json\/wp\/v2\/just-the-facts"}],"about":[{"href":"https:\/\/www.voicesforvaccines.org\/es\/wp-json\/wp\/v2\/types\/just-the-facts"}],"wp:attachment":[{"href":"https:\/\/www.voicesforvaccines.org\/es\/wp-json\/wp\/v2\/media?parent=15477"}],"wp:term":[{"taxonomy":"jtf_topic_subjects","embeddable":true,"href":"https:\/\/www.voicesforvaccines.org\/es\/wp-json\/wp\/v2\/jtf_topic_subjects?post=15477"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
