To help raise awareness and openness regarding the effects of genetic mRNA vaccines on fertility and pre/neonatal health, NORTH Group is coordinating an outreach. We have written two letters that can be sent to:
Doctors and nurses specialized in Obstetrics and Gynaecology (Ob-Gyn)
Midwives
Fertility clinics and professionals working there including embryologists
Sperm and tissue banks etc.
Many professionals working in areas including Ob-Gyn, midwifery and fertility have raised the alarm about concerning findings in their field e.g. miscarriages, stillbirths, pregnancy complications, increase in infertility and menstrual disorders.
Professionals from several countries have contributed to the drafting of these letters, with expertise in Ob-Gyn, molecular biology and reproductive biology, infertility and IVF, perinatal genetics, midwifery, psychology, etc. All agree that there has been a breach of medical ethics, a rejection of the precautionary principle and a lack of proper pharmacovigilance in the case of mRNA vaccines.
We believe that a respectful and understanding tone in communication is important for both the recipient and the sender.
• The letters are available in English on the NORTH Group website and will also be shared in other languages as they become available. Contact us if you would like a version in Word.
• You can download the letters, adapt and translate them to your own language.
• You can send the letters to relevant professionals in your name, or in the name of your organisation.
• If you send the letters in the name of NORTH Group and/or with the logo, the content must remain unchanged, except for translational adaptions.
• Please send any responses you receive to contactus@northgroup.info, or ask people to respond to this email address.

See our Substack article on the first letter to reproductive health professionals:
Dear Colleague,
Following our initial communication, NORTH Group writes to share significant new evidence raising urgent concerns about the safety of COVID-19 mRNA vaccines for reproductive health. A growing body of peer-reviewed research and epidemiological data points to safety signals that we believe warrant your professional attention and dialogue.
The core of our concern is the application of the mRNA/lipid nanoparticle (LNP) platform to a healthy population, including those of reproductive age, without adequate long-term safety testing. The precautionary principle was bypassed. We now face emerging trends that cannot be ignored:
A significant decline in birth rates across Europe, beginning in early 2022, temporally aligned with mass vaccination campaigns to the fertile age group.
New clinical studies indicating a higher incidence of fetal loss following vaccination in early pregnancy and a substantial decrease in live birth rates among vaccinated women.
Preclinical animal data demonstrating potential biological mechanisms for harm, including irreversible damage to ovarian reserve and elevated inflammatory markers in reproductive tissues.
Rising reports of severe obstetric complications, such as postpartum haemorrhage, in national quality databases.
These findings, detailed below in the appendix, represent clear safety signals that are not adequately addressed by regulators. While the burden of proof for safety lies with manufacturers and regulators, the duty of care for our patients lies with us.
As professionals in reproductive health, your observations are critical. We ask that you review the appended evidence and share with us your clinical experiences over the past five years. We wish to compile an evidence-based report of what is occurring in the area of reproductive health independent of any health agenda. We would like to know if you have observed changes in fertility outcomes, pregnancy complications, or neonatal health that you find concerning?
We seek an open, scientific dialogue to ensure the highest standards of patient safety and medical ethics. Your insights, even if shared anonymously, are invaluable.
The decisions we make now will shape the future of reproductive health for decades to come. We urge you to consider this information and join this critical conversation.
Please contact us at contactus@northgroup.info.

APPENDIX: Summary of Evidence
1. Lack of Pre-Approval Safety Data for Reproductive Health
COVID-19 mRNA vaccines were recommended for pregnant women despite being excluded from initial clinical trials.
Post-approval manufacturing changes introduced new components (e.g., synthetic plasmid DNA, SV40 promoter-enhancer) without additional Phase 3 trials.
2. Epidemiological Data: Declining Birth Rates
A historic ~15% decline in birth rates began in Q1 2022 across most European countries following mass vaccination. This correlation demands further investigation into possible causation.
3. Key Recent Studies
Manniche et al. (2025): A Czech nationwide cohort study found a 33% lower rate of live birth in vaccinated vs. unvaccinated women (18-45).
Guetzkow et al. (2025): Analysis of 220,000 Israeli pregnancies found mRNA vaccination in weeks 8-13 was associated with higher-than-expected fetal loss, a signal not seen with influenza vaccines.
Thorp et al. (2025): A VAERS analysis identified significant safety signals for 37 pregnancy-related adverse events, including miscarriage and neonatal complications.
Karaman et al. (2025): A preclinical study in rats showed a >60% reduction in primordial follicles (the non-renewable egg supply) and a significant drop in AMH after administration of an mRNA vaccine, suggesting a potential mechanism for irreversible ovarian damage.
4. Clinical and Mechanistic Concerns
Postpartum Haemorrhage: Danish mandatory reporting shows a marked increase in severe PPH (>1500ml) since 2021.
Immunological Mechanisms: A 2024 study found a significant rise in anti-phospholipid antibodies post-vaccination, which are associated with recurrent miscarriage.
Nanoparticle Toxicity: The LNPs used are a novel delivery system with unknown long-term biodistribution and effects on reproductive tissues.
