Russia published the results of its COVID-19 vaccine — and they don’t live up to the hype

The levels of neutralizing antibodies were quite low in this study, compared with other published vaccine trials. So too were the T cell responses (the other arm of the immune system’s adaptive response).

One interpretation of this is that these vaccines do not induce good neutralizing protection. Alternatively, the methods used to measure these immune responses may not have been optimal. In the absence of international reference standards, we can’t tell if this vaccine is better or worse compared with others.
