There have always been restrictions and requirements for fertility treatments, including vaccination requirements. It never feels fair that we have all these extra criteria to meet, but when we consider the resources being allocated for us and the potential risks of harm if people haven't met the requirements, then from a more academic perspective most of the requirements make sense.
In the case of Covid, successful fertility treatment automatically moves us into an at-risk group - pregnancy and Covid can lead to some very bad outcomes. Questions the healthcare services will need to have considered are: Is it ethical to place people at these increased risks? Is it an efficient use of NHS resources to provide these interventions to the same population as before or is it necessary to change the criteria for intervention, given the risks? How do the increased risks affect outcomes?
While we have data about the older variants of Covid, data about Omicron is still being gathered. What we do know, though, includes the fact that, if you consider Omicron as a separate virus, it's one of the fastest-spreading viruses ever encountered. We don't yet know how it's going to affect hospitalisation, pregnancy-related complications, at-risk groups... That data is still being gathered. I was a bit surprised that this new requirement wasn't implemented when Delta was the dominant strain, so I'm not surprised to see it being introduced now.
The main objection/issue I have with it is the lack of communication and notice. This is a change which is very significant for many people across the country, yet it's had virtually no discussion or publicity. There may still be people on waiting lists who aren't vaccinated and aren't aware that they now need to be. I'd also be interested to see what consultations took place to help inform the decision-making - too many decisions are made about us, without us - I hope this isn't the case, but I suspect there may well have been a distinct lack of representation of women and people undergoing fertility treatments within the group making the decision.
