Vaccines against COVID-19 induce the immune system to produce neutralizing antibodies, and boosters ensure their continued production. Researchers from Japan now report that their elderly population produced a very low antibody titer when compared with the younger cohorts. They used a unique fingertip blood collection method to analyze whole blood for circulating antibodies against SARS-CoV-2. The researchers also propose a triage system to address the elderly patients with poor or low post-booster immune response.
