PRIMARY outcome

Timeframe: One year, three years, and five years after the fourth dose vaccination.

Population: Analysis was done on the ATP cohort for persistence of each respective timepoint in all evaluable subjects who had assay results available for at least one tested antigen and who had a blood sample taken between 309 and 645 days (Year 1 data), 1039 and 1375 days (Year 3 data) and 1770 and 1882 days (Year 5 data) after administration of fourth dose.

Results up to 5 years after the fourth dose are presented.
