Biological machinery inside cells &#8220;read&#8221; this single strand of genetic information, which acts like an instruction manual that directs the cell to build proteins of certain specifications.<\/p>\n<p>The coronavirus, once it has infected a cell, uses mRNA to trick the cell into manufacturing more copies of the virus. But Pfizer and Moderna use mRNA to tell the cell how to build proteins that resemble the SARS-CoV-2 virus that causes COVID-19 infections, similar enough to impart immunity on a vaccinated person, but not cause an infection.<\/p>\n<p>With the two vaccines now racing toward US Food and Drug Administration approval, <a href=\"https:\/\/www.bu.edu\/neidl\/profile\/ronald-b-corley\/\">Ronald Corley<\/a>, professor of medicine at Boston University and director of the National Emerging Infectious Diseases Laboratories, and <a href=\"https:\/\/www.bu.edu\/neidl\/profile\/florian-douam\/\">Florian Douam<\/a>, a MED assistant professor and NEIDL virologist and vaccine expert, offer their takes on how the Pfizer and Moderna vaccines could change the course of the pandemic:<\/p>\n","protected":false},"excerpt":{"rendered":"<p>With two potential COVID-19 vaccines on the way, experts say we&#8217;re &#8220;in new territory&#8221; in [&hellip;]<\/p>\n","protected":false},"author":10092,"featured_media":2476122,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"quote","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[14],"tags":[185622,426,8825],"class_list":["post-2474372","post","type-post","status-publish","format-quote","has-post-thumbnail","hentry","category-health-medicine","tag-covid-19","tag-vaccines","tag-viruses","post_format-post-format-quote","university-boston-university"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.8 (Yoast SEO v24.6) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Experts: 2 COVID-19 vaccines bring us into &#039;new territory&#039; - 糖心视频<\/title>\n<meta name=\"description\" content=\"Pfizer and Moderna announced they have developed effective coronavirus vaccines, but how will they work?
