Directly from NIH. So much bullshitting. So much research funded by NIH. NIH on patents and in discussion w/vaccine makers for patent rights. Women bearing vaccine injured infants, infants reacting badly to their mother's milk following vaccination. Too much other evidence that women't reproductive organs are effected more severely than a 'temporary' increase of cycle time. So much conflict of interest in these studies. Can't do r/n but there have got to be studies out there NOT funded by the NIH on this issue.
From the Jan. 2022 updated NIH article:
"In a recently published study supported by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), researchers found that the length of the menstrual cycle — the time between periods — temporarily increased by an average of less than one day in people who received a dose of the COVID-19 vaccine, compared with unvaccinated people."
From the October 2021 article (same page):
"NICHD recently awarded five institutions one-year supplemental grants totaling $1.67 million to explore potential links between COVID-19 vaccination and menstrual changes. Researchers at Boston University, Harvard Medical School, Johns Hopkins University, Michigan State University, and Oregon Health and Science University will investigate whether such changes may be linked to the COVID-19 vaccine itself or if they are coincidental, the mechanism underlying any vaccine-related changes, and how long any changes last."
The real thing is, all you menstruating people (because men self identify as menstruating or what?) that you might be responsible for the changes because of lifestyle changes during the pandemic. (blame the victim??)
