Phase 1/2 trial of SARS-CoV-2 vaccine ChAdOx1 nCoV-19 with a booster dose induces multifunctional antibody responses, (Nature Medicine, 17th December)
Viral vector coronavirus vaccine, ChAdOx1 nCoV-19 (AZD1222)
https://www.nature.com/articles/s41591-020-01179-4
190 vaccines currently in development
Neutralizing antibodies against the viral spike protein correlate with protection
Additional antibody functions may also be important in preventing infection
Two jabs, 56 days apart
SD/SD n = 20
SD/LD n = 32
A booster dose is safe and better tolerated than priming doses
After second dose
Increased anti-spike neutralizing antibody titers,
Increased cell mediated immunity
Increased neutrophil and monocyte phagocytosis
Increased complement activation
Increased natural killer cell activation
SD / SD
Stronger antibody responses
T cell responses did not increase with either booster dose
These data support the two-dose vaccine regime that is now being evaluated in phase 3 clinical trials
