claim: sars-cov-2-specific peripheral t follicular helper cells correlate with neutralizing antibodies and mortality during convalescence.
evidence_1: but, we also show that ptfh responses against other sars-cov-2 proteins correlate with antibody neutralization, indicating a possible role for intrastructural help.", "these responses suggest that sars-cov-2-specific ptfh continue to increase over time during convalescence.")
