"80% of all miscarriages happen in the first trimester."

Sorry to rain on the anti-vax parade. Given the small sample size (104 pregnancies), this is well within the margin of error. In other words, this is the normal, expected amount. The background rate. No difference observed with the vaccine.
What does the ACOG have to say about the vaccine data with pregnancy?
"no differences have been seen when comparing pregnant women participating in the v-safe pregnancy registry with the background rates of adverse pregnancy outcomes." -American College of Obstetricians and Gynecologists
See post 51. It's 3,959 pregnancies, and just 104 miscarriages. So far, it's below the norm (possibly because most of the expected mothers are healthcare workers). As always, it's an author with an agenda twisting facts like a pretzel.
