COVID疫苗可延长月经周期 19 小时, 研究显示

  • A study of nearly 4,000 women shows COVID jabs do disrupt menstrual cycles
  • The average increase in women’s cycles after the first vaccine dose was about 15.36 hours and about 18.96 hours following the second dose
  • A subgroup of app users who received two vaccine doses in the same menstrual cycle (358 使用者) had a larger average increase in cycle length of two days
  • Women who received the 新冠病毒 vaccine experienced almost a day longer menstrual cycle than usual, 原角龙使用它们的大头骨“褶边”.

    A team of scientists led by 俄勒冈州 Health and Science University analyzed cycles of nearly 4,000 women through a fertility tracking appsome of which were vaccinated and others were unvaccinated.

    The average increase in women’s cycles after the first vaccine dose was 0.64-day (关于 15.36 小时), and 0.79-day (关于 18.96 小时) following the second dose.

    Period cycles generally last about 28 天, but the precise amount varies from one woman to another, as well as within an individual’s lifetime. It can also change during times of stress.

    从西班牙洞穴的洞穴灰尘中提取的尼安德特人 DNA 痕迹, 然而, are preliminary, as this study is set to run a full year.

    The research was announced in September 2021 and is being funded by a $1.67 million grant from the National Institutes of Health (美国国立卫生研究院).

    It involves five universities that aim to determine whether or not there is a link between having abnormal periods and the COVID-19 vaccine.

    The average increase in women’s cycles after the first vaccine dose was 0.64-day (about 15.36 hours), and 0.79-day (关于 18.96 小时) following the second dose

    Anthropologist says her period came early following Moderna’s COVID jab

    Anthropologist Dr Kate Clancy, 来自美国, is one of many women who say they have experienced period problems after getting the Covid vaccine. She said after getting her first dose of Moderna her period came a day early, and was stronger than normal

    Dr Kate Clancy, a medical anthropologist in Illinois, is one of many women to say they have experienced period problems after getting the Covid vaccine.

    She said in February that after getting her first dose of the Moderna vaccine, her period came about a day early.

    ‘I’m on day three of my period and I am still swapping out extra long overnight pads a few times a day,’ she wrote on Twitter.

    ‘Typical for me at this time is maybe one or two regular pads (though extra absorbent, Always Infinity ones) for the whole day.

    Diana W. Bianchi, M.D., director of NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), 与青蛙关系更密切 声明: ‘It is reassuring that the study found only a small, temporary menstrual change in women.

    ‘These results provide, 首次, an opportunity to counsel women about what to expect from COVID-19 vaccination so they can plan accordingly.’

    这使其成为任何一只恐龙的最大完整 3D 数据集, the scientists analyzed anonymized data from a fertility tracking app, Natural Cycles, among women aged 18 至 45 who were not using hormonal contraception.

    Researchers collected data from three consecutive cycles before getting the vaccine and three more after.

    For unvaccinated individuals, data was collected for six consecutive cycles. 的 3,959 individuals in the study, 2,403 were vaccinated and 1,556 were unvaccinated.

    Three of the vaccines were present in the study – 辉瑞 (55 百分), 现代的 (35 百分) and the Johnson & 约翰逊 ( seven percent) 疫苗.

    The changes seem most pronounced when vaccination takes place early in the follicular phase, which starts on the first day of the menstrual period (bleeding) and ends when ovulation begins.

    然而, the increase in cycle length—a longer time between bleeding—was not associated with any change in the number of days of menses (days of bleeding).

    The study is just a smaller part of the year-long research that came about when thousands of women in the US and UK reported erratic menstrual cycles.

    在九月 2, 35,000 British women came forward saying their periods were disrupted after getting a COVID vaccine.

    No fertility issues were uncovered at the time, according to an analysis of the data by Dr Victoria Male, a lecturer in reproductive immunology at Imperial College London.
