Abstract This study evaluated the relationship between Covid-19 vaccination and menstrual bleeding disturbances using a large national registry linkage including 666,467 women 20 40 years of age residing in Norway on January 1st, 2019. Information vaccination—BNT162b2 mRNA-1273 — was obtained from Norwegian registry. Diagnoses (absent/scanty, excessive, irregular/frequent menstruation, intermenstrual bleeding) general practitioner database. We examined new-onset Cox regression comparing vaccinated to unvaccinated women, where contributed follow-up time as until day vaccination. In addition, we conducted self-controlled case-series analysis, sensitivity analysis excluding all those who remained throughout pandemic, evaluate role unmeasured confounding. observed an increased risk several after against Covid-19, ranging adjusted HR (aHR) 1.18 (95% CI: 1.04, 1.33) for 1.29 1.23, 1.36) periods. However, estimates were fully attenuated when at end (aHRs 0.97 1.08). No differences identified according vaccine dose or type. Our case series confirmed no first vaccination, though there slightly 61 days with 2. conclusion, modestly appeared reflect confounding by never received vaccinations, associations did not remain compared before among ever women.

The coronavirus disease 2019 (COVID-19) outbreak caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2) has affected various medical fields worldwide. However, relatively few studies have examined the impact of COVID-19 infection and vaccination on in vitro fertilization (IVF) outcomes changes antibody concentration follicular fluid (FF). A total 45 women were prospectively recruited assigned to 3 groups: uninfected non-vaccinated control group (Control group), infected (COVID + vaccinated (Vaccination group). Serum (FF) estradiol, progesterone, concentrations measured. There no statistical differences number retrieved oocytes (P = .291), mature .416), good-quality embryos .694) among groups. In group, BNT162b2 exhibited a significantly lower trigger-day serum estradiol/MII oocyte level (110.6 pg/mL) than other vaccines (289.5 .006).
