Four years later, Tagliaferri was at the 1952 Summer Olympics in Helsinki, Finland and was competing in the same events as she did in London four years earlier. In the 100 metres she finished in second place in her heat behind American Mae Faggs, in the second round she ran a time of 12.9 seconds and finished last in the heat and thus did not advance in the event. In the 4 × 100 metres relay running with Vittoria Cesarini, Milena Greppi and Giuseppina Leone they were drawn in the same heat as the teams from the United States and Great Britain, so they finished in third place and did not qualify for the final.
