The UK study on this page recommends just 400 IU, and is behind a $36 paywall
Yes, 400 IU during pregnancy prevents rickets.
However, far more is needed: during pregnancy: at least 2,000 IU and preferably 6,000 IU

This article summarises the evidence and related guidance on managing vitamin D status in pregnant women, and provides an update on the ways in which women can obtain the necessary supplements.BACKGROUND
Vitamin D is not only integral to calcium homeostasis and bone health, but it also has multiple other sites of action throughout the body, including the pancreas, skin, intestine, and immune system. In the UK, dietary sources of vitamin D are limited and account for only 10–20% of the total body store; natural sources include oily fish, egg yolk, and red meat, while fortified foods include infant and toddler formula milks, some breakfast cereals, and margarines. The majority of vitamin D is from skin synthesis following exposure to sunlight, although in the UK the necessary wavelength of ultraviolet radiation is only available between April and mid-October.1,3Most laboratories measure serum 25-hydroxyvitamin D (25[OH]D) as a reflection of current vitamin D stores, which equates to the levels produced cutaneously and through …
