The first dose elicits heterogeneous T cell responses and induces gene expression changes that prime the immune system, enhancing responses to the second dose. Individuals classified as fast responders (FR) exhibit higher baseline T cell counts and distinct gene expression profiles compared to slow responders (SR). Additionally, baseline gene expression and cytokine signatures associated with inflammation influence responsiveness, and the first dose can modify these gene profiles, potentially improving subsequent immune responses.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The study highlights that RZV alters immune cells\u2019 gene activity, particularly related to T cell responses, which may explain the necessity of two doses for optimal vaccine efficacy in aging populations. These findings suggest potential strategies for improving vaccine efficacy in aging populations, such as modifying the baseline immune state or tailoring vaccination approaches.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Click <\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/40592255\/\" rel=\"nofollow noopener\" target=\"_blank\"><span style=\"font-weight: 400;\">here<\/span><\/a><span style=\"font-weight: 400;\"> to access the full scientific paper.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\t\t\t<style>\r\n\t\t\t\t#sfba_subscribe_form_358 .subscribeform1 {\r\n\t\t\t\t\twidth: 512px;\r\n\t\t\t\t\tborder: 0px solid rgba(0,0,0,0);\r\n\t\t\t\t\tfont-family: 'Verdana';\r\n\t\t\t\t\tbackground-color: #759e2c;\r\n\t\t\t\t\tbackground-image: url('');\r\n\t\t\t\t}\r\n\t\t\t\t#sfba_subscribe_form_358 #sfba-main-form-container.subscribeform1 .sfba-form-sub-heading {\r\n\t\t\t\t\tcolor: #102341;\r\n\t\t\t\t}\r\n\t\t\t\t#sfba_subscribe_form_358 #sfba-main-form-container.subscribeform1 .sfba-form-privacy-heading {\r\n\t\t\t\t\tcolor: ;\r\n\t\t\t\t}\r\n\t\t\t\t#sfba_subscribe_form_358 #sfba-main-form-container.subscribeform1 .sfba-form-heading {\r\n\t\t\t\t\tcolor: #ffffff;\r\n\t\t\t\t}\r\n\t\t\t\t#sfba_subscribe_form_358 .subscribeform1 .sfba_subscribe_form__fields .sfba-form-fields {\r\n\t\t\t\t\tborder-color: rgba(0,0,0,0);\r\n\t\t\t\t}\r\n\t\t\t\t#sfba_subscribe_form_358 .subscribeform1 .sfba-form-consent-fields-main label,\r\n\t\t\t\t#sfba_subscribe_form_358 .subscribeform1 .sfba-form-consent-fields-main {\r\n\t\t\t\t\tcolor: #ffffff;\r\n\t\t\t\t}\r\n\t\t\t\t#sfba_subscribe_form_358 .subscribeform1 #sfba-form-button {\r\n\t\t\t\t\tbackground-color: #4c6938;\r\n\t\t\t\t\tcolor: #ffffff;\r\n\t\t\t\t\tfont-size: 14px;\r\n\t\t\t\t}\r\n\t\t\t\t.subscribeform6 #sfba-form-button {\r\n\t\t\t\t\tbackground-image: url(https:\/\/desertking.com\/wp-content\/plugins\/wp-subscribe-forms-pro\/includes\/..\/images\/sent.png);\r\n\t\t\t\t}\r\n\t\t\t\tinput.sfba-form-fields::placeholder { \/ Chrome, Firefox, Opera, Safari 10.1+ \/\r\n\t\t\t\t  color: #7E7E7E;\r\n\t\t\t\t  opacity: 1;
