Activity Title: COVID-19 Vaccinology Update: Will New Variants Necessitate New Vaccines
Release Date: March 5, 2021
Estimated Time to Complete Activity: 55 minutes
Statement of Need:
The emergence and spread of COVID-19 variants raises new questions and scientists must debate whether the variants undercut the effectiveness of first-generation COVID-19 vaccines. The new strains of SARS-CoV-2, first identified in the United Kingdom (B.1.1.7), Brazil (P.1) and South Africa (B.1.351), have developed a substantial number of mutations, especially in the S-protein, that seem to reduce the effects of antibodies crucial to fending off infection. This webinar is a follow up to ISID’s webinar on “COVID-19 Vaccinology Update: Development, Use and Effect on Public Health” released in January 2021. Prof. Malavige and Prof. Madhi will discuss the implications of these mutations on vaccine response and how vaccine manufacturers plan to update their vaccines to better target the emerging variants. Additionally, Prof. Madhi will discuss new results from phase 3 trials and what it will take to achieve herd immunity.
Faculty:
Neelika Malavige is a Professor and head of the Department of Immunology and Molecular Medicine, the Director of the Centre for Dengue Research, University of Sri Jayewardenepura, Sri Lanka and an academic visitor at the MRC Human Immunology Unit, University of Oxford. She is also a Fellow of the Royal College of Physicians, London and a Fellow of the Royal College of Pathologists, UK.
Shabir A. Madhi is currently the Dean of the Faculty of Health Sciences at the Wits University. His former positions include Professor of Vaccinology in the School of Pathology at the University of the Witwatersrand and Director of the world-renowned Medical Research Council Vaccines and Infectious Diseases Analytics Research Unit (VIDA). Madhi is the National Research Foundation/Department of Science and Innovation SARChI Chair in Vaccine Preventable Diseases and he is Co-Director of African Leadership in Vaccinology Expertise (ALIVE). He chairs the National Advisory Group on Immunization in South Africa. His qualifications include MBBCh (Wits), MMed (Wits), FCPaeds(SA), Ph.D.
