PR DELFRAISSY “ENOUGH OPTIMIST” FOR THE CONTINUATION
“We had not expected that the fourth wave would slow down so quickly,” admitted Professor Jean-François Delfraissy on Thursday in an interview with the newspaper The world. A situation that the President of the Scientific Council explains by “the very high level of vaccination in France” and “the very high effectiveness of vaccines, of unexpected magnitude”, while conceding the existence “of other factors that escape us a little”.
What about the weeks to come? “Fairly optimistic, even if we cannot totally exclude the appearance of a new variant”, Professor Delfraissy anticipates “two scenarios”: “Either a small wave of the Delta variant, with a contained impact on the healthcare system, or a significant increase in viral circulation, but without major impact on the healthcare system. ”
“Provided we keep the barrier gestures, we should be able to cope with a recovery”, continues the immunologist according to whom, “in the medium term, the virus could become endemic, even seasonal, both because the Delta variant is contained by the vaccine and because its capacity to evolve is limited “. Unless a new mutation in the virus disrupts things. “The other possibility is the emergence of a variant which is even more transmissible or which would escape the immunity conferred by the vaccine. In the long term, obviously, the crisis is not over,” he warns.
