I don't understand why you're swerving to yet another unrelated point @vinegarasacleaner
None of this is suggesting why pregnant women should not be offered vaccination in pregnancy.
Nor is it addressing any of the fake claims HART have made, or suggesting any robust research they have done that counters mainstream views.
You're conflating loads of different things and I'm not sure why you're suddenly bringing up COVID policies, for which we know various governments did not use the most up to date evidence to inform.
And lo and behold, the latest Cochrane review of evidence finds very little (or no) impact of mask mandates on infection rates
And to be factually correct, no it did not. It was not able to draw conclusions (i.e., the evidence is of such low quality that conclusions could not be drawn)
....their alleged impact on transmission
Again, this is not factually correct. Effectiveness relating to transmission and onward transmission was identified from population based studies, there was never any issue regarding the quality of findings, but such that estimates quickly became outdated in an ever-changing pandemic with a rapidly mutating virus.
It remains the case that if you do not get infected with coronavirus you cannot pass it on, and given that vaccines still do reduce the likelihood of an infection, they provide some benefit in reducing transmission.
There were many actual scientists, not just the charlatans in HART, who urged caution and caveats in reporting the benefits of vaccination, and said it was impossible to keep suppression policies up to date with the current evidence.
Again, this is all irrelevant to the current thread though!
