claim: antibodies in covid-19 patients occur quickly
evidence_1: in combination with certain previous findings on covid-19 antibodies, the researchers concluded that their results \"might indicate the risks of using covid-19 'immunity passports' and support the prolongation of public health interventions, including social distancing, hygiene, isolation of high-risk groups and widespread testing.\"", "decreases in the neutralizing antibodies were seen in 81% (30/37) of the asymptomatic group and 62% (23/37) of the symptomatic group.", "antibody levels dropped by 71.1% in asymptomatic patients and 76.2% in the symptomatic group.",
