täältähän löyty paljon alan asiantuntijoita, jotka pystyy selvästi vertaisarvioimaan jopa tutkimuksia
No eivät ne tieteellisten paperien analysointi välttämättä tarvitse juuri ko. alalta mitään erityistä asiantuntijuutta. Sitä varten on ne tarkastajat ja sitten jos noissa tulee jotain epäselvää niin ne oikeat alan asiantuntijat kyllä puuttuvat asiaan. Hormonitasojen heitteleyitä on toki mitattu, mutta niiden vakavuus on sitten eri asia. Toki lisätutkimus on aina paikallaan, mutta tässäkin mihinkään erityiseen huoleen ei ainakaan toistaiseksi ole:

"Common side effects of covid-19 vaccination listed by the UK’s Medicines and Healthcare Products Regulatory Agency (MHRA) include a sore arm, fever, fatigue, and myalgia.
1 Changes to periods and unexpected vaginal bleeding are not listed, but primary care clinicians and those working in reproductive health are increasingly approached by people who have experienced these events shortly after vaccination. More than 30 000 reports of these events had been made to MHRA’s yellow card surveillance scheme for adverse drug reactions by 2 September 2021, across all covid-19 vaccines currently offered.

Most people who report a change to their period after vaccination find that it returns to normal the following cycle and, importantly, there is no evidence that covid-19 vaccination adversely affects fertility. In clinical trials, unintended pregnancies occurred at similar rates in vaccinated and unvaccinated groups.
2 In assisted reproduction clinics, fertility measures and pregnancy rates are similar in vaccinated and unvaccinated patients.

MHRA states that evaluation of yellow card reports does not support a link between changes to menstrual periods and covid-19 vaccines since the number of reports is low relative to both the number of people vaccinated and the prevalence of menstrual disorders generally.
7 However, the way in which yellow card data are collected makes firm conclusions difficult. Approaches better equipped to compare rates of menstrual variation in vaccinated versus unvaccinated populations are needed, and the US National Institutes of Health has made $1.67m (£1.2m; €1.4m) available to encourage this important research.

Menstrual changes have been reported after both mRNA and adenovirus vectored covid-19 vaccines,
1 suggesting that, if there is a connection, it is likely to be a result of the immune response to vaccination rather than a specific vaccine component. Vaccination against human papillomavirus (HPV) has also been associated with menstrual changes.
9 Indeed, the menstrual cycle can be affected by immune activation in response to various stimuli, including viral infection: in one study of menstruating women, around a quarter of those infected with SARS-CoV-2 experienced menstrual disruption.
