First, I would like to stress that there is absolutely no evidence that any of the Covid-19 vaccines can affect fertility, including for those undergoing fertility treatment. Vaccination against Covid-19 is the safest and most effective way of protecting pregnant women and their babies from infection and serious illness.
More than 275,000 pregnant women in the UK and USA have received either a Pfizer/ BioNtech or Moderna vaccine, with no evidence of harm being identified. In fact, new research shows that 4,950 cases of Covid-19 have been confirmed during pregnancy since the beginning of the vaccine programme in Scotland, with 77% of these cases occurring in unvaccinated women. 17% of babies born within 28 days of their mother developing Covid-19 were delivered prematurely, more than double the background rate. Sadly the research also shows that baby deaths are more common among women who had Covid-19 in the 28 days before delivery.
I would add that prior to the pandemic, there were already conditions for receiving NHS funded fertility treatment, including vaccination against rubella and German measles which can cause serious problems for unborn babies if their mothers are infected during pregnancy.
Given the concerns for women and their babies, as outlined above, fertility treatment has been deferred for unvaccinated women. During the course of the pandemic, unvaccinated pregnant women and recent post-natal women have been adversely affected by Covid-19. These concerns persist with Omicron, though vaccination protects against this.
The decision to defer fertility treatment for unvaccinated women was taken when only very limited data on Omicron existed. Now that infections are coming down, I understand that the data will be revisited soon.
