New article on durable immune responses after BNT162b2 vaccination
Lena Hansen et al. have recently published a new article “Durable immune responses after BNT162b2 vaccination in home-dwelling old adults” in journal Vaccine: X, where the authors have looked into the durability of humoral and cellular immune responses after BNT162b2 vaccination and SARS-CoV-2 infection in elderly and younger adults.
Their research showed that vaccine-induced spike-specific IgG and neutralizing antibodies were consistently lower in the older than younger vaccinees. This contributes to the knowledge about kinetics of the humoral and cellular immune response in the elderly who were vaccinated against SARS-CoV-2 or infected by the corona virus, and highlights the need for two doses, which might guide future vaccine design.
