Spreading The Time Between Ebola Vaccine Receipt, And Booster(s) Improves Overall Antibody Response...


Just a quick Friday squib (since my men's brackets are busted). . . as I head down, out of the high mountains -- to potentially 90 degree weather in Boulder tomorrow(!).

It comes from a well-respected source: The Journal of Nature -- and we see that delaying the time for a booster of the Ebola vaccine improves the robustness of the human body's antibody production -- yes, this is power alley stuff. Do take a gander:

. . .Here, we elucidated the longitudinal humoral immune repertoire over 3 years following prime and boost rVSV∆G-ZEBOV-GP vaccinations administered 18 months apart in healthy adults compared to participants randomized to no boost. This delayed booster vaccination induced long-lasting EBOV-neutralizing antibodies that persisted up to 36 month at levels similar to peak titers after a single dose. Phage display libraries, expressing linear and conformational epitopes of EBOV glycoprotein (GP), demonstrated a highly diverse and durable antibody epitope repertoire following prime boost vaccination. Delayed booster vaccination recalled memory B cells, promoted anti-GP IgG class switching and induced antibodies specific to GP with Fcγ receptor interaction and functional antibody-dependent cellular cytotoxicity and phagocytosis.

The 18-month interval led to 13-fold higher antibody affinity maturation than a single dose, maintained up to 36 months. Overall, delayed rVSV∆G-ZEBOV-GP booster vaccination promoted a diverse, stronger, durable, predominant IgG, highly affinity-matured antibody response to GP. . . .




Onward, grinning. And, here’s to hoping my CU Buffs’ women hoopsters are able to take down the mighty Illini, tomorrow night. Be excellent to one another.
