Chuck,
I've got a question, let me start with the short version, then I'll add more detail for clarity about what I'm getting at.
Short version: So, my wife had the J&J one shot vaccine in early April, then the Moderna booster in Mid November. While it's probably too early for real data, I'm wondering based on your knowledge how her resistance to omicron is likely to be compared to a mRNA+booster (three shots) regimen. And, is there any reason to think folks like her might need a third shot anytime soon?
Longer ramblings:
Despite the different delivery methods between the adenovirus-based J&J versus mRNA-based Pfizer or Moderna shots, they largely do the same thing as far as I understand it: they coax the body into producing a bit of spike protein (the same one, among the three shots) over a period of hours to days, and the body then reacts to the spike protein and develops and immune response over a period of days to a month or so. The rate-over-time at which the body produces the spike protein and thus the various immune response components varies among the shots, based on nuances of the delivery mechanism. But, the data I've seen is that the two mRNA two-course regimens are broadly comparable in their effect, and the J&J single shot regimen produces less of a response, largely due to being a single shot regimen rather than due to the delivery mechanism. Again, because the body is complicated, nuances aren't trival; they actually have an impact at the end. So we see some statistically significant differences when we analyze immune components in cohorts of folks that have had different immunizations. But still, I'm working on an assumption that three mRNA shots over time likely gives a better immune response than one J&J shot plus one mRNA booster.
My wife works face to face with kids in a mental health setting, and televisits work poorly for what she does, and masks are impractical due to blocking so much nonverbal communication needed for her work, so she is "out there." I worry about her as her health is delicate.
Do you have any thoughts based on what we are hearing about omicron? The more immune response, the more effectiveness against the partially vaccine resistant omicron. So, since it seems to be a quantity play at the moment, I wonder about her getting a third shot sometime in the next month or two.
