Résumé : In the original version of this article ‘Abdelwahed Chtarto’ was omitted from the author list. This author has now been added to the author list in 10th position. Additionally, the following acknowledgement was accidentally omitted from the original article: ‘We are grateful to Catherine Melas, from the ULB, and Laetitia Thieren, from the CHUV, for their valuable help on producing the viruses used in this study’. This has been corrected in both the PDF and HTML versions of this article.
