Of course, a booster dose will have a beneficial effect. However, that will be of SHORT duration. It is only due to the fact that your ´old’antibodies (Abs) will increase in concentration ( due to ´antigenic sin’ : everyone can google that), not so much because you will raise Abs of high affinity towards the new S variant in the boost! So, what this means is that massive administration of booster doses will only promote propagation of even ´more highly infectious’ immune escape variants and expedite full resistance. Fauci is no longer a scientist but has become a politician: They typically have no long-term ( or even mid-term) vision and are unable to see beyond the enf of their nose. For how much longer will people continue to believe in their short-sighted narrative? It’s basically all about a short sightseeing tour in heaven before landing in hell! - Geert vanden Bossche
