As it turns out, the Johnson & Johnson vaccine never gained the traction of the mRNA vaccines in the US (the last stat I saw had something like only 12 million going that route). As someone who got the J&J, I’ve been wondering for a while about also getting at least a first dose of Moderna or Pfizer, given vaccines have become so plentiful in my area that we’re doing walk-ins.
For a long while there wasn’t much information on it. There still really isn’t, but at least the question itself has been popping up a lot in the last couple of weeks.
Here’s an opinion piece from someone who just went ahead and did the two mRNA doses. It’s not clear if it was the right decision.
Here’s one from yesterday from a virologist who “boosted” via a Pfizer dose to avoid becoming a breeding ground for variants (her words). The article goes on to talk to experts who mostly say we need to wait on the science (the article lists one NIH study just kicking off).
Finally, Bloomberg has a pretty well researched article on the topic.

I don’t have a strong opinion on this and I’m not planning on doing it anytime soon, but like some folks quoted in the article, we just see very little information published on J&J, so sometimes it feels like flying in the dark, especially when a steady stream of mRNA articles is appearing.
This is as much a “what do you think?” thread as a place to update news.
