Correction to: Nature Nanotechnology https://doi.org/10.1038/s41565-021-00946-9, published online 11 August 2021.

In the version of article initially published, there were errors in Table 1. In the first row, the name of the Pfizer/BioNTech vaccine should have read “BNT162b2,” (not BNT162b1) while the biological agent should have read “mRNA (stable perfusion S protein)” (not RBD of S protein). In the fifth from last row, the name of the University of Queensland/Seqirus vaccine should have read “V451/MF59” (not MF59), while the third sentence of the footnote has been amended to read “Previously clinical use” (not Prev. approved tech). The changes have been made to the HTML and PDF versions of the article.
