On 4th March 2019 Pope Francis has announced Vatican Apostolic Archives’ fonds from pontificate of Pius XII (1939-1968) will be avaible a year later. The news of the opening was written by the world press. Research fellows of the Fraknói Researcher Group were waiting also for the opening. Unfortunately the coronavirus kept people away from the historical opening on 2nd March 2020. But Krisztina Tóth research fellow of Vilmos Fraknói Vatican Historical Research Group was there and she has started her newest research. Krisztina Tóth was glad to see that in the opened fonds are numerous hungarian related documents. She had only two days for researching in the Vatican Apostolic Archives because italian authorities also found an infected person in Rome. Therefore Vatican Apostolic Archives has disestablish the opening hours for an uncertain time. Krisztina Tóth is waiting for the end of epidemic and reopening Archives as other research fellows of the Researching Group.
