This paper looked at antibody responses to the second dose of COVID-19 vaccination in care home residents taking part in the Vivaldi study and how these changed over time. VIVALDI report on 1317 samples from 402 residents (median age 86 years) and 632 staff (median age 50 years).

It was found that residents had strong and durable responses to vaccines that were comparable to the antibody levels that have been described in the general population. This is reassuring as frail care home residents have been the worst affected by the pandemic; these findings suggest that they have good immune responses to vaccination.
