Effect of SpikoGen subunit vaccine administration during pregnancy on fetal development of rats.
Article in Clinical and experimental vaccine research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: The effects of coronavirus disease 2019 vaccination on fertility and pregnancy have turned out to be a main topic of public attention. Inactivated or recombinant protein vaccines are a reliable and safe method but mostly suffer from weak immunogenicity just in case formulated with a suitable adjuvant. The purpose of this research was to assess the impacts of new SpikoGen subunit vaccine administration during pregnancy on organogenesis in the rat fetus, which is a novel achievement in teratogenesis studies. Materials and Methods: In the first group (G1) animals received normal saline. A dose of 25 µg of the vaccine was administered to groups of rats as follows: groups 2, 3, 4, and 5 received two doses of vaccine on different days before and after start of pregnancy. On day 21, after the caesarean process, the effects of the vaccine were estimated by morphological, skeletal, and histological studies. Results: Administration of the SpikoGen vaccine had no significant effect on weight, head diameter, tail length, and length of the fetuses to their tail. There were no malformations, toes and legs were fully developed, and all internal organs of the fetus were completely formed. Also, there was no difference in the overall skeletal opacity and density between the control and treatment groups. Conclusion: The results of this study indicated no negative impacts of the vaccine administration during pregnancy on developing of fetuses in rats.
