COVID-19 vaccine update – November 2021

Kia ora,

Those clients who are going through fertility treatment, or about to start treatment, may be wondering about the safety of being immunised against COVID-19.  We know that this will be of particular interest to those working in sectors which have made vaccinations mandatory, and if fertility treatment fits the criteria for medical exemption.

Based on international research, there is no evidence that the COVID-19 vaccine effects fertility so fertility treatment can continue during immunisation.  Therefore, unless there is a health concern, our advice is not to delay vaccination.

In a release on 29th October 2021, RANZCOG (Royal Australian & NZ College of Obstetricians and Gynaecologists) has advised:

RANZCOG has issued clear and unequivocal advice that mRNA vaccines for COVID-19 are recommended for all people trying to conceive (either spontaneously, or through IVF), pregnant, or breastfeeding.

This advice is based on robust data supporting safety in these circumstances. Specifically, there is no evidence of a negative impact on fertility, no evidence of an increased risk of miscarriage, fetal harm, pregnancy outcomes or the health of the breastfed neonate.

Conversely, infection with COVID-19 is associated with an increased risk of severe disease, hospitalisation, admission to intensive care, ventilation, and death, in pregnant women, and an increased risk of prematurity and stillbirth.

RANZCOG reiterates our advice that trying to conceive, pregnancy, and breastfeeding, are not reasons for medical exemption from receiving an mRNA COVID-19 vaccine.

For specific information about the impact of the COVID-19 vaccination on the quality and rhythm of egg, sperm and menstrual cycle, see this article from The Immunisation Advisory Centre: Can mRNA COVID-19 vaccine affect fertility or affect future babies?

Evidence shows there is no biologically plausible reason why this vaccine could have any effect on our genes or fertility and there is strong evidence it does not.

We have a Q&A on our website with your questions about the COVID-19 vaccine answered.

We know this will be a personal decision and we encourage you to discuss any concerns.  If you have any queries about the COVID-19 vaccine and your treatment, please email  or call 0800 483 105 and talk to your nursing team.
