Memory B cell development after asymptomatic or mild symptomatic SARS-CoV-2 infection.

ABSTRACT:

Background

The development of memory B cells after asymptomatic SARS-CoV-2 infection is not well understood.

Methods

We compared Spike antibody titers, pseudovirus neutralizing antibody titers, and memory B cell responses among SARS-CoV-2 PCR positive Marine recruits who either reported asymptomatic or symptomatic infection.

Results

36 asymptomatic participants exhibited similar Spike IgG titers, Spike IgA titers, and pseudovirus neutralization titers compared to 30 symptomatic participants. Pseudovirus neutralization and Spike IgG titers showed significant positive correlations with frequency of memory B cells.

Conclusions

Among young adults, asymptomatic SARS-CoV-2 infection induced antibody and memory B cell responses comparable to mild symptomatic infection
