Effect of COVID-19 inactivated vaccine on peripheral blood anti-β2-GPI antibody and outcomes in vitro fertilization-embryo transplantation.

Corona Virus Disease 2019 (COVID-19) is an acute respiratory infection and a global public health event. The level of aβ 2 GPI is significantly up-regulated in COVID-19 patients. The impact of inactivated vaccination against COVID-19 on aβ 2 GPI and in vitro fertilization and embryo transfer (IVF-ET) remains unknown amidst the universal administration of COVID-19 vaccines. We conducted a retrospective study to assess the impact of COVID-19 inactivated vaccination on aβ 2 GPI levels and its effect on superovulation and pregnancy outcomes. We found aβ 2 GPI level is significantly up-regulated after vaccination. There was no statistical difference in mature egg rate, 2PN fertilization rate, day 3 high-quality embryo rate, blastocyst formation rate, embryo implantation rate and miscarriage rate between the vaccine group and control group. Our findings showed vaccination with COVID-19 inactivated vaccine can elevate the level of aβ 2 GPI in peripheral blood but have no effect on the outcomes of controlled ovarian hyperstimulation and pregnancy in IVF-ET. • This is the first study to explore the correlation between the level of aβ 2 GPI in patients after inactivated COVID-19 vaccination and the outcome of ovulation hyperstimulation and pregnancy in IVF-ET. • The results showed aβ 2 GPI level is significantly up-regulated after inactivated COVID-19 vaccination. • The results showed no statistical difference in mature egg rate, 2PN fertilization rate, day 3 high-quality embryo rate, blastocyst formation rate, embryo implantation rate and miscarriage rate betwee n the vaccine group and control group.
