Significant respiratory virus activity in the EU/EEA, with #influenza & #RSV epidemics ongoing.

Vaccination campaigns against respiratory pathogens continue in many EU/EEA countries, and people who are eligible for vaccination are encouraged to get vaccinated.

Coming up next week - another part of our #GenEpiBioTrain online trainings!

This time we will focus on #RSV with the help of #InstitutePasteur.

The aim is to provide participants with in-depth knowledge of RSV, its genomic diversity, evolution, available treatments, & emerging vaccine strategies.
