My amateur reading of the paper: They say that there's a chance still it can reduce some of the symptoms and reduce the need for hospitalization of the South African variant (B.1.351), but it doesn't do a great job at preventing infections in the first place. > we determined that 8 out of 12 (75%) of serum samples from 12 recipients of the Russian Sputnik V Ad26 / Ad5 vaccine showed dose response curve slopes indicative of failure to neutralize rcVSV-CoV2-S: B.1.351. > Furthermore, we acknowledge that in vivo protective efficacy can be derived from Fc effector functions of antibodies that bind but do not neutralize.
