I mostly agree, but these experts need to calculate how many shots this really is (~150Mil) and then look at how many shots are still needed in the rest of the world (~10Bil). So if everyone who had a single shot also got a booster, it would increase this time by 1.5 (or less since distribution and production rates increase with time)? Prioritizing the elderly in developing nations (rather than the wealthy and politically connected) and speeding vaccine production (likely Adenovirus rather than MRNA due to encapsulation and cold-chain bottlenecks) would have order of magnitude larger effects on deaths than preventing booster shots. The number of wasted shots is closing in on the number likely to be administered. Delaying immunization school children for the school year (barring much higher than expected immune side effects in unpublished data) is likely going to be another own-goal for the FDA/CDC.
