L’extrême rapidité de la mise en place des vaccins contre le #sars-cov2 n’a pas pour seule (grosse) inconnue l’intensité des effets secondaires qui en découleront, mais aussi la durée d’efficacité de ces vaccins, cette dernière conditionnant le nombre de personnes qui pourront être vaccinées.
If the vaccine protective response is going to one year or less, then how are we going to cover the susceptible population every year? [...] It’s impossible. And we are not going to know if the vaccine protective response is going to last five years because we desperately need the vaccine and there will be short cuts implemented. The reason why vaccines take 10-12 years to develop is because you need to check if in a few years the vaccine is still protective to the recipient.
