GlaxoSmithKline plant-based COVID vaccine - Mick - 05-18-2021 https://www.marketwatch.com/story/a-plant-based-vaccine-from-a-glaxosmithkline-alliance-with-medicago-shows-strong-antibody-response-11621349865 Ten times the COVID-19 antibodies that infected/recovered people have. Is the result the same for other vaccines? RE: GlaxoSmithKline plant-based COVID vaccine - M_T - 05-19-2021 The GSX press release had  "about 10 times higher than those in a panel of sera from patients recovering from COVID-19" Ah... here are the details. on CoVLP+AS03 After 2 doses, at day 42, the neutralizing antibody (NAb) titers were roughly 2000 for both adults and older adults. I found a comparison of the 9 vaccines approved somewhere in the world. It reports neutralizing antibody titer for Moderna as 654 and Pfizer as 361.  It reports the Novavax NVX-CoV2373 NAb titer as 3906 and the Clover SCB-2019 NAb titer as 1810-3320. I do NOT know that simply having a higher NAb titer is sufficient to indicate it is a better vaccine.  Obviously safety ia major factor.  Also, there is an issue about being effective against variants. "The vaccine candidate developed by Medicago, a Coronavirus-like particle (CoVLP), is a self-assembling VLP [virus-like particle] that displays trimers of recombinant S protein of SARS-CoV2 embedded into the lipid bilayer of the nanoparticles." |
