By Bhavana KunkalikarSep 19 2022Reviewed by Danielle Ellis, B.Sc. In a recent study published in Vaccine, researchers assessed the impact of severe acute respiratory syndrome coronavirus 2 vaccines on human fertility.
About the study In the present study, researchers summarized and assessed the available information related to the potential effect of COVID-19 vaccines on female and male fertility. The included studies were assessed with respect to the methodological quality of the study design. The cohort studies were assessed with the Newcastle-Ottawa scale that evaluated quality parameters, including study group selection, comparability of the groups, and ascertainment of the results.
Furthermore, 51.7% of the total studies were performed on females, 37.9% on males, and 10.3% on both populations. Approximately 52% of the studies included in vitro fertilization /IVG patients, including 11 studies on females and two on males. Two studies performed in Russia, one in Turkey, and one in Israel involved healthy women subjects.

SARS-CoV-2 infection, vaccination, and antibody response trajectories in adults: a cohort study in Catalonia - BMC MedicineBackground Heterogeneity of the population in relation to infection, COVID-19 vaccination, and host characteristics is likely reflected in the underlying SARS-CoV-2 antibody responses. Methods We measured IgM, IgA, and IgG levels against SARS-CoV-2 spike and nucleocapsid antigens in 1076 adults of a cohort study in Catalonia between June and November 2020 and a second time between May and July 2021. Questionnaire data and electronic health records on vaccination and COVID-19 testing were available in both periods. Data on several lifestyle, health-related, and sociodemographic characteristics were also available. Results Antibody seroreversion occurred in 35.8% of the 64 participants non-vaccinated and infected almost a year ago and was related to asymptomatic infection, age above 60 years, and smoking. Moreover, the analysis on kinetics revealed that among all responses, IgG RBD, IgA RBD, and IgG S2 decreased less within 1 year after infection. Among vaccinated, 2.1% did not present antibodies at the time of testing and approximately 1% had breakthrough infections post-vaccination. In the post-vaccination era, IgM responses and those against nucleoprotein were much less prevalent. In previously infected individuals, vaccination boosted the immune response and there was a slight but statistically significant increase in responses after a 2nd compared to the 1st dose. Infected vaccinated participants had superior antibody levels across time compared to naïve-vaccinated people. mRNA vaccines and, particularly the Spikevax, induced higher antibodies after 1st and 2nd doses compared to Vaxzevria or Janssen COVID-19 vaccines. In multivariable regression analyses, antibody responses after vaccination were predicted by the type of vaccine, infection age, sex, smoking, and mental and cardiovascular diseases. Conclusions Our data support that infected people would benefit from vaccination. Results also indicate that hybrid immunity results in superior antibody responses and
