Neutralization of the SARS-CoV-2 Deltacron and BA.3 Variants
NEJM, May 18, 2022
- In serum samples obtained after 3 to 4 weeks of the second dose of the mRNA-1273, neutralizing-antibody titers were 3.3 times as low against the BA.3 variant and 44.7 times as low against the deltacron variant as compared with the response against the D614G variant.
- After booster, neutralizing-antibody titers were 2.9 times as low against the BA.3 variant and 13.3 times as low against the deltacron variant as against the D614G variant.
- In general, neutralization escape of the deltacron variant paralleled that of the BA.1 and BA.2 variants, whereas the BA.3 variant remained largely sensitive to neutralization.
- The patients who were hospitalized during the omicron wave had broader neutralization of all the tested omicron variants than did those hospitalized during the delta wave
