Small study shows antibody growth from AstraZeneca, Sputnik Light COVID-19 vaccine mix

A small-scale clinical study of the combined use of the AstraZeneca and Sputnik Light vaccines against COVID-19 has shown strong antibody growth in a majority of the study's participants, the Russian Direct Investment Fund said on Monday. The data was collected from 20 people who took part in a 100-person study in Azerbaijan that began in February. They first received the AstraZeneca shot followed by the one-dose Russian-made Sputnik Light shot 29 days later, RDIF said.
