Sanofi, Mod­er­na beef up the case for giv­ing flu, Covid-19 vac­cines to el­der­ly in the same vis­it

Giv­ing Sanofi’s flu vac­cine to­geth­er with a boost­er shot of Mod­er­na’s Covid-19 vac­cine to the el­der­ly ap­pears to be just as safe as ad­min­is­ter­ing the two apart, the two com­pa­nies re­port­ed, join­ing a small cho­rus of drug­mak­ers bring­ing good news about co-ad­min­is­tra­tion of sea­son­al shots.

The study en­rolled around 300 adults who were 65 or old­er.

All of the par­tic­i­pants had re­ceived two dos­es of the Mod­er­na mR­NA vac­cine at least five months pri­or.

The high-dose for­mu­la­tion was specif­i­cal­ly de­vel­oped to of­fer high­er pro­tec­tion to the el­der­ly, who are at high risk for com­pli­ca­tions due to both in­fluen­za and Covid-19.
