International Nonproprietary Names for Variant COVID-19 Vaccine Active Substances

by System Administrator -

The INN Expert Group has adopted a nomenclature for COVID-19 vaccine substances dedicated to SARS-CoV-2 variants of concern (VOCs). The WHO INN Programme encourages vaccine developers to submit INN requests for COVID-19 vaccine substances including those directed against SARS-CoV-2 VOCs and urges regulatory authorities to facilitate their implementation. Please consult the corresponding document titled “International Nonproprietary Names for Variant COVID-19 Vaccine Active Substances” for further details.
