Brighton Collaboration Case Definition for GBS Applied to Vaccines for Prevention of RSV (CDC Morbidity and Mortality Weekly Report

In May 2023, the Food and Drug Administration (FDA) licensed Arexvy and Abrysvo vaccines for prevention of respiratory syncytial virus (RSV) lower respiratory tract disease in adults aged ≥60 years. In prelicensure trials, Guillain-Barré syndrome (GBS) was identified as a potential safety concern. Symptoms and health impacts reported during the week after RSV vaccination were described for V-safe participants aged ≥60 years who were vaccinated during May 3, 2023–April 14, 2024, and completed one or more daily surveys. Primary VAERS adverse event reports after RSV vaccination for persons aged ≥60 years were described by serious and nonserious classification and MedDRA PTs. Reporting rates for GBS reports that met the Brighton Collaboration case definition were estimated using available doses administered as the denominator. Read more >

Vaccine Safety in the News

WHO Says It Is Trying to Expedite Mpox Vaccination in DRC – But Faces Multiple Hurdles (Health Policy Watch) — WHO officials said that they are trying to expedite delivery of mpox vaccines to outbreak-stricken DR Congo through talks with the world’s only two mpox vaccine manufacturers, as well as extending appeals for vaccine donations and negotiations with DRC Officials.

Participants in Nigeria Vaccinated in First-ever Phase 2 Lassa Fever Vaccine Clinical Trial (CEPI) — Participants in Nigeria have been vaccinated with a Lassa fever vaccine candidate in the first Phase 2 clinical trial of any Lassa vaccine. More than 600 participants in Ghana, Liberia, and Nigeria are expected to enroll in the IAVI-sponsored trial, funded by CEPI.

Thousands Believe Covid Vaccines Harmed Them. Is Anyone Listening? (New York Times) — All vaccines have at least occasional side effects. But people who say they were injured by Covid vaccines believe their cases have been ignored.


Development of WHO Immunization Policy and Strategic Guidance (WHO) — This guidance describes the methods and processes of the Strategic Advisory Group of Experts (SAGE) on Immunization in developing evidence-based recommendations, WHO vaccine position papers, and other immunization policy guidance. Its aim is to facilitate the work of SAGE, its working groups and the WHO Secretariat, as well as to inform a wider readership, such as national immunization managers and national immunization technical advisory groups.

A Proposed Model to Build Capacity for Emergency Use Authorization for Therapeutics—Guidance for National Medicines Regulatory Authorities (USAID and USP) — This document presents practical recommendations for strengthening operational policies and procedures for therapeutics EUAs, establishing clear review timelines, allowing for rolling submissions, using standardized application forms and checklists, and investing in electronic regulatory information systems.

Advancing Clinical Research with Pregnant and Lactating Populations: Overcoming Real and Perceived Liability Risks (National Academies of Sciences, Engineering, and Medicine) — The US Congress called on the National Academies to convene a committee to examine the real and perceived risks of liability arising from research conducted with pregnant and lactating women. The resulting report explores and finds limited evidence of legal liability for the inclusion of pregnant and lactating women in clinical research, contradicting perceptions of heightened liability.

Real-World Data and Real-World Evidence in Regulatory Decision Making (CIOMS) — In recent years, many medicines regulatory agencies have expressed increased willingness to consider real-world evidence (RWE), that derives from the review and/or analysis of real-world data (RWD), to support claims of efficacy or effectiveness as well as of safety. This increased willingness is changing the regulatory environment in which RWE is generated and used. This consensus report aims to describe the potential use of RWE for decision making; RWD and data sources; key scientific considerations in the generation of RWE; and ethical and governance issues in using RWD.

Featured Research

Obstetric Complications and Birth Outcomes After Antenatal Coronavirus Disease 2019 (COVID-19) Vaccination (Obstetrics and Gynecology) — A new large study finds mRNA COVID-19 vaccination during pregnancy was not associated with an increased risk of adverse pregnancy outcomes. This information will be helpful for patients and clinicians when considering COVID-19 vaccination in pregnancy.

A Comparison of Four Self-Controlled Study Designs in an Analysis of COVID-19 Vaccines and Myocarditis Using Five European Databases (Vaccine)  — A new methodological paper assesses the possible extent of bias due to violation of a core assumption (event-dependent exposures) when using self-controlled designs to analyze the association between COVID-19 vaccines and myocarditis.

Postmarketing Vaccine Safety Assessments (JAMA Network) — How can vaccine safety be monitored to ensure that individuals are well informed about their individual risks? In an article published in JAMA, Kathryn M. Edwards and Marie R. Griffin make the case for standardized, consistent definitions of adverse events and share that Brighton Collaboration case definitions can be effectively used across different studies.

Landscape Review of Active Vaccine Safety Surveillance Activities for COVID-19 Vaccines Globally (Vaccine) — Earlier this year we spoke with Parisa Shamaeizadeh and Rebecca Chandler about the COVID-19 Vaccine Safety Studies Project, driven by the International Vaccine Access Center at Johns Hopkins BSPH and funded by CEPI. Read the editorial about the project on and the published paper in Vaccine.

Maternal and Perinatal Health Research During Emerging and Ongoing Epidemic Threats: a Landscape Analysis and Expert Consultation (BMJ Global Health) — This paper identifies research efforts relevant to pregnant women affected by disease outbreaks, highlights gaps and challenges, and proposes solutions to addressing them in a coordinated manner. Having explored how existing maternal and perinatal health research platforms could be leveraged to address existing gaps and how they could be used to meet the need for a comprehensive global emergency response, it was determined that structures and mechanisms would need to be established to approach dealing with new epidemics or pandemics holistically and coherently.

Defining and Reporting Adverse Events of Special Interest in Comparative Maternal Vaccine Studies: a Systematic Review (Vaccine) — The GAIA (Global Alignment on Immunisation Safety Assessment in Pregnancy) consortium was established in 2014 with the aim of creating a standardised, globally coordinated approach to monitoring the safety of vaccines administered in pregnancy. The consortium developed twenty-six standardised definitions for classifying obstetric and infant adverse events. This systematic review sought to evaluate the current state of adverse event reporting in maternal vaccine trials following the publication of the case definitions by GAIA, and the extent to which these case definitions have been adopted in maternal vaccine safety research.
