Speaker 0 asked how many of his patients or pregnant women he knows experienced miscarriages after receiving COVID-19 vaccines.
Speaker 1 responded with observational data from his practice. He said that in fall of the previous year, about 60% of pregnant patients in his practice were vaccinated, which he noted is commensurate with Florida’s overall vaccination rate of about 60–65–70%. Most of his pregnant patients received three injections, with very few receiving four or more, and the majority received their injections in 2021 and early 2022. He referenced a Substack by Jessica Rose from November 2022 that presents his data pictorially, and noted that his data runs from January 2020 to November 2022.
In 2020, he observed many newly registered obstetric patients (represented by blue bars for first-trimester new pregnancies). He stated there were the most deliveries, suggesting a lockdown-related effect. He then discussed miscarriage rates. He noted that standard textbooks and articles quote a normal miscarriage rate of 13–15%, but he has never seen that clinically. A 2020 study by Nairt et al. reported the actual first-trimester miscarriage rate as 5–6%, and he considers that even that to be somewhat high. He reported his own average miscarriage rate in 2020 as 4% month-to-month.
He stated that his miscarriage rate from year to year increased: in 2021, the average month-to-month rate was 7–8%, with a peak in November that year, when a non-clinical staff member told him there had been eight miscarriages in a single month in a practice that delivers 20–25 patients, a “huge number.” In 2022, the average month-to-month rate rose to 15% (up to November). In December 2022, there were 41 newly registered patients, and 13 of them lost their babies, which is 25% for that month. In January and February 2023, the rate remained high, and only normalized around June, with a subsequent slight rise and fall by September.
Regarding whether the miscarriages were associated with vaccination, he said it is hard to determine: he could tell that about 60% of his patients were vaccinated, but many new patients had not yet appeared in his practice, since he is the sole clinician who asks every patient about vaccination, brand, and timing, as well as prior COVID infection. He noted that asking a patient who miscarries if they received an injection could come across as accusatory, so obtaining complete data is challenging. He concluded with the observation that the information is difficult to ascertain precisely and that not wanting a patient to feel blamed complicates collecting definitive links between vaccination and miscarriage.
