I don’t think the J&J vax ever figured much in the Grand Strategy to push vaccines except early-on when it filled the demand gap. Recall that there were severe difficulties in handling the Pfizer vaccine that was slowing distribution. Once that was solved J&J had that well-publicized clotting issue. It also seems like Fauci is chiefly concerned with getting everybody inoculated with the mRNA vaccine which J&J is not.
My wife & I got the J&J vax in early spring of 2021. About the time this administration began pushing the idea of boosters I began to check for pharmacies that were carrying the J&J — it was gone. Nobody had it in southeastern Pennsylvania. We decided not to get boosted because we remain skeptical of the mRNA technology and it’s long-term safety.
It became more obvious when he said get mRNA as a booster in lieu of J&J booster.
I did J&J, too...and no booster to date.
I recall that short period of time they halted the J&J and Trump said it was ridiculous to stop it, said it was really because J&J was not a darling of the government like Pfizer and Moderna.
We also chose the J&J because it wasn’t Pfizer or Moderna!
