women were becoming pregnant at the same rates as before the pandemic.

Using German health insurance data — because Swiss data are not yet available — he showed the number of women seeking pregnancy tests and visiting doctors to be treated for pregnancy remained constant throughout 2021 and 2022.

There was even slight ongoing growth, and a spike related to the mini-baby boom of 2021.

That makes COVID-19 vaccine-induced spontaneous abortion the most plausible hypothesis for the drop in birth rates — because the same number of women were becoming pregnant, but fewer of them were carrying their pregnancies to term.

Supporting that claim, data from German health and Swiss insurers show that beginning in the fourth quarter of 2021, there are clear and significant increases in the number of pregnancy complications treated and in the length of hospital stays following birth — both of which had been trending downward for years.

German data also indicate that the number of stillbirths was up 20% in the fourth quarter of 2021.
