A major new study from world-renowned scientists at Johns Hopkins University has confirmed that Covid “vaccines” are reducing human populations by lowering birth rates.
The peer-reviewed study, led by Dr. Kunchok Dorjee, is the most comprehensive evaluation to date of the association between Covid “vaccination” and reproductive disturbances.
The massive investigation included a staggering 1.9 million women from around the world.
The team of researchers analyzed 17 individual global studies related to birth rates and menstrual cycles among women who had received mRNA injections.

The study warns of “significant risks” to women’s fertility and birth rates following Covid “vaccination,” aligning with previous warnings of “reproductive destruction” caused by the injections.
The findings of the study were published in PLOS ONE journal.

During the study, the researchers reviewed literature from January 2021 to November 2023, across Medline, Embase, and Web of Science.
They selected 17 studies meeting stringent inclusion criteria.
Outcomes assessed included changes in menstrual cycle length, heavier flow, intermenstrual bleeding, and post-menopausal bleeding.
A fixed-effects meta-analysis was conducted with Shore’s adjusted confidence intervals to account for heterogeneity.
The study included a total of 1,911,755 participants, with 7 prospective cohorts, 4 retrospective cohorts, and 5 cross-sectional.
The “vaccine” brands included were Pfizer, Moderna, Janssen (J&J), and AstraZeneca.
The women included in the study were mostly menstruating, non-pregnant, non-lactating women ages 18–50.
The researcher also included three studies involving post-menopausal women.
The study found a 19% higher relative risk of increased menstrual cycle length following Covid “vaccination” (standardized risk ratio [sRR]: 1.19; 95% CI: 1.11–1.26).
On average, the first vaccine dose was associated with a 0.34-day increase in cycle length.
The second dose is with a 0.62-day increase.
However, this effect was resolved by the second cycle post-vaccination, suggesting the change was temporary.
When analyzed by vaccine brand, Pfizer and Moderna were associated with a 15% increased risk of cycle lengthening (sRR: 1.15), AstraZeneca with a 27% increase (sRR: 1.27), and Janssen with a 69% increase (sRR: 1.69), though the latter was based on a relatively small sample (n = 751).
