In Fig. 4c of this Article, owing to an error made during production, the brown and green lines were both labelled ‘IC VEGFC mRNA + anti-PD-1 + anti-CTLA4’. The brown line should be labelled ‘FT IC VEGFC mRNA + anti-PD-1 + anti-CTLA4’. We thank reader David Giles for pointing out the error. The original Article has been corrected online.
