SARS-CoV-2 resistance to antibodies and protease inhibitors - Dr Emi Takashita, National Institute of Infectious Diseases, Tokyo, Japan

Influenza A virus polymerase acidic protein E23G/K substitutions weaken key baloxavir drug-binding contacts with minimal impact on replication and transmission - Dr Jeremy Jones, St. Jude Children’s Research Hospital, Memphis TN, USA

Monoclonal antibodies and promising antivirals for RSV – the challenges  - Professor Tony Piedra, Baylor College of Medicine, Houston, TX, USA

Webinar 3: ‘The Present and Future of Treatment Oriented Surveillance’

Surveillance for avian influenza

AVG Overview

The isirv Antiviral Group (isirv-AVG) was established as a special interest group of isirv at the time of merger in April 2011 of the former Neuraminidase Inhibitor Susceptibility Network (NISN) with isirv. Its specific objectives are to promote understanding of the clinical use of antivirals against respiratory viruses, collate and provide up to date information on the emergence of antiviral resistance, and communicate expert commentary on preclinical and clinical development of potential novel/new antivirals. Read More


   isirv Antiviral Group (isirv-AVG) 10th Anniversary

The isirv Antiviral Group was established in 2011 following the merger of the Neuraminidase Inhibitor Susceptibility Network (NISN) with the International Society for Influenza and Other Respiratory Virus Diseases (isirv). Read more

To fulfil its objectives of promoting understanding of the development and clinical use of antivirals against respiratory viruses and the emergence of resistance, the Group has organised a series of AVG conferences on specific topics in different geographical locations plus other smaller specialist meetings and workshops.

The Group gratefully acknowledges the contribution of its partners and the generous financial support from many privateand public organisations that have ensured the success of the Group’s programme of events over the past 10 years.

 Recent AVG Events

Therapeutics for COVID-19, a special virtual conference, 6-8 October 2020
The 3-day programme addressed the latest advances in the development of antivirals and other therapeutics for use against COVID-19 and possibilities for improved clinical management. Oral and e-poster presentations are available. Read more
AVG Polymerase Inhibitor Resistance Meeting, at the Offices of the Task Force for Global Health, Atlanta, USA, 7-8 August 2019
The participants at this small specialist meeting, including public health, academic and corporate representatives who are conducting studies on the new antivirals targeting the influenza RNA polymerase, met to discuss the impact of resistance to these inhibitors. A report of the meeting is incorporated in an Assessment of the Current State of the Art report published in Antiviral Research and now on the AVR journal web site as a highlighted article. Read more
