hVIVO formed a Joint Venture in 2016 with PepTcell Limited called Imutex Limited, with hVIVO owning 49%, to develop vaccines against influenza (flu) and mosquito borne diseases such as Zika, Malaria and other flaviviruses.
hVIVO’s has an extensive history, that dates back to the UK Common Cold Unit in Salisbury which ran human challenge studies from 1946 until 1989. The facility was a former military hospital that was donated by Harvard University and began human challenge studies to try to find a cure for influenza.
The company founders, Professor John Oxford and Dr Robert Lambkin Williams, worked at the Common Cold Unit alongside Dr David Tyrell, and after it closed, went on to setup Retroscreen Virology Limited out of Queens Mary University in 1989.
Retroscreen, renamed hVIVO in 2015 as part of its IPO on the London Stock Exchange, continues its challenge study work right up to the present day. hVIVO is now the world leader in providing human challenge studies to test infectious and respiratory product and we have the widest portfolio of challenge models available in influenza, respiratory syncytial virus (RSV), human rhinovirus (HRV), asthma, COPD, cough, malaria, and most recently COVID-19. A number of the same techniques used at the Common Cold Unit are still used by hVIVO today, though needless to say they have modernised.
