Could you cite this assertion? The data that I've reviewed shows a pretty robust immune response, especially given a booster within 1 month. This is specifically for the mRNA vaccines by Pfizer and Moderna. Please also remember, when speaking of the United States, around 15% of the population has already been infected by SARS-COV-2[1], and even the most pessimistic of epidemiologists say that herd immunity is around 60%. So we need "infect" 45% more of the population to give COVID-19 a knockout blow. even 50% efficacy (which I believe is the standard lower bound for an approved vaccine), 300 million doses should do quite nicely (600 if you count boosters, which I should have). Those are all worst case scenarios. Most likely, the efficacy will be higher than 50% (maybe not 90%, but I think 75% is safe) and most likely herd immunity is below 60% (due to heterogeneity in mixing and t-cell "immunity").
