The original version of this Article contained an error in the legend of Figure 2, which incorrectly read ‘Neutralization titers against Wuhan-1 SARS-CoV-2 pseudovirus for serum obtained from individual animals 21 days following immunization with DCFHP-alum’. The correct version states ‘42 days’ in place of ’21 days’. This has been corrected in both the PDF and HTML versions of the Article.
