^#Progression free survival was calculated as time from the date the consent was signed until evidence of disease progression or last follow-up without progression (+). *Overall Survival was calculated as time from consent date until death or last follow-up (+). ND, not done because patient received 2 or less vaccines; NA, sample not available. Immune response was marked as negative (-) or positive (+) as described in the manuscript.
