Increased risk of fetal loss after COVID-19 vaccinationSir,We read with interest the article by Thorp et al. (2022) published as a pre-print and in Journal American Physicians Surgeons their letter to editor suggesting need include data our meta-analysis evaluating miscarriage following use SARS-CoV-2 vaccines (Rimmer al., 2023).The authors present findings simulation model that was constructed using from Vaccine Adverse Events Reporting System (VAERS) database USA between 1 January 1998 30 June 2022.The chose construct estimating total population who received either vaccine, number flu doses given, incidence adverse events globally.Interestingly, decided report compared instead simply reporting on true reported VAERS database.Clearly, any is subject high degree bias when choosing assumptions underpinning its construct.Thorp seem examine hypothesis are inherently more harmful than because they were rolled out rapidly.However, it not clear how useful such or assumption would inform clinical practice.Our live birth vaccines.Therefore, does meet inclusion criteria for meta-analysis.Should provide robust factual vaccines, we be happy update accordingly.

Abstract Artificial intelligence (AI)-driven language models have the potential to serve as an educational tool, facilitate clinical decision-making, and support research academic writing. The benefits of their use are yet be evaluated concerns been raised regarding accuracy, transparency, ethical implications using this AI technology in publishing. At moment, Chat Generative Pre-trained Transformer (ChatGPT) is one most powerful widely debated models. Here, we discuss its feasibility answer scientific questions, identify relevant literature, assist writing field human reproduction. With consideration scarcity data on topic, assessed ChatGPT writing, from six meta-analyses published a leading journal text generated by was compared original blinded reviewers. While can produce high-quality summarize information efficiently, current ability interpret questions limited, it cannot relied upon for literature search or accurate source citation due spread incomplete false information. We advocate open discussions within reproductive medicine community explore advantages disadvantages implementing technology. Researchers reviewers should informed about models, encourage authors transparently disclose use.

COVID-19 vaccination rates are lower in women of reproductive age (WRA), including pregnant/postpartum women, despite their poorer COVID-19-related outcomes. We evaluated the experiences 3568 U.K. WRA, 1983 (55.6%) experiencing a pandemic pregnancy, recruited through ZOE COVID Symptom Study app. Two staggered online questionnaires (Oct–Dec 2021: 3453 responders; Aug–Sept 2022: 2129 responders) assessed status, vaccination, and attitudes for/against vaccination. Descriptive analyses included type(s), timing relative to age-based eligibility delay (first >28 days from eligibility), rationale, with content analysis free-text comments. Most responders (3392/3453, 98.2%) were vaccinated by Dec 2021, motivated altruism, supportiveness general, low risk, concerns. Few declined (by Sept/2022: 20/2129, 1.0%), citing risks (pregnancy-specific longer-term), pre-existing immunity, personal/philosophical reasons. delayed although (vs. other WRA) received later (median 3 vs. 0 after eligibility, p < 0.0001). Despite high uptake, concerns adverse effects, misinformation (including healthcare providers), ever-changing government advice, complex decision making.

We follow general fertility rates (GFRs) in Switzerland up to 2022, with a focus on their dynamics during and after pandemics. Historical influenza pandemics (1889–90, 1918–20, 1957) have consistently led temporary declines births between six nine months the pandemic peak. High of miscarriage may explain these findings. After 1889–90 1918–20 pandemics, short-term baby booms occurred. For recent Covid-19 pandemic, appear more complex. The GFR had already been declining since 2018, before hit Switzerland. During shortly first two waves 2020, there was an increase conceptions, leading higher 2021: shutdown measures brought planned pregnancies forwards. Subsequently, declined from February 2022; one possible explanation is that were intentionally postponed until vaccination.
