A new study suggests that COVID-19 vaccines made by AstraZeneca and the Pfizer-BioNTech alliance are broadly effective against the highly contagious Delta and Kappa strains of the CCP (Chinese Communist Party) virus, the pathogen that causes COVID-19. The Oxford University study, of which a peer-reviewed pre-proof has been published in Cell (pdf), sought to gauge the ability of blood serum from people vaccinated against COVID-19 and from those who recovered naturally to neutralize the Delta (B.1.617.2) and Kappa (B.1.617.1) variants, formerly referred to as the “Indian” variants as that is where they were first observed. While the researchers found that both the convalescent and vaccine blood sera had a reduced ability to neutralize the Delta and Kappa variants as compared to “ancestral Wuhan related strains,” there was “no evidence of widespread antibody escape” as seen with the Beta (B.1.351, formerly “South Africa”) variant, “suggesting that the current generation of vaccines …
