(Reuters) - Seniors can safely get the high-dose flu vaccine and an mRNA COVID-19 booster dose at the same time, a new study confirms.

The study's 306 participants, all older than 65, were randomly assigned either to receive Sanofi's Fluzone High-Dose Quadrivalent influenza vaccine and a third shot of Moderna's mRNA vaccine at the same time, or either of the vaccines alone.

Blood samples obtained before and 21 days after vaccination showed that giving the two vaccines together did not affect the resulting immune response, with similar antibody levels generated in participants in each of the three groups, according to a report in The Lancet Respiratory Medicine.

A spokesperson for Sanofi said combined administration of the COVID-19 and influenza vaccines "did not raise any safety concerns and the study team is continuing to follow study participants through 6 months after vaccination."
