This is probably completely true, but I will add a caveat from all the data I’ve read. The shot messed with the period cycle of a lot of women who took it, the change in that cycle alone with a more spontaneous period or more frequent one would likely at least add to a lower fertility if not account for a good part of the drop. For example, there’s the standard cycle which has been called the monthly flow, this is adaptable by multiple outlying factors, the “vaccine” shot is an indicative factor in disruption of the menstrual cycle, but it hasn’t been shown to be permanent. What has also spiked amongst women who took the “vaccine” is a massive spike of antidepressants, and they’re also the largest subgroup who have taken birth control since puberty. All three of those are massive red flags for maintaining a healthy body cycle and for women, being fertile.
