The Peter Doherty Institute for Infection and Immunity is a research institute located in Melbourne, Australia. The Doherty Institute is named after the name of Laureate Professor Peter C. Doherty (Nobel prize winner in 1996). This institute is a joint venture between The University of Melbourne and The Royal Melbourne Hospital.
Doherty Institute has advised the Australian government for the transition to nation reopening based upon the vaccination progress in the modelling report. This 4-phase transition plan depends upon the percentage (70%/*80%) of the fully vaccinated eligible population(16 years or older). In February 2022, the Doherty Institute advised against periodic six-month boosters.
