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.
