Safety observation of COVID-19 inactivated vaccine in immature mice.
Objective: To investigate the safety of COVID-19 inactivated vaccine in immature mice.
Methods: We selected 3-week-old immature BALB/c mice, continuously observed until 7 weeks old after continuous immunization with fully inactivated vaccine (initial strengthening), and sacrificed BALB/c mice at 7 weeks old, and used H&E, Masson, mast cells and Ki-67 staining to analyze the changes of heart, liver, spleen, kidney, lung and brain. In addition, RNA was extracted from important organs such as the heart, liver, spleen, kidney, lung, and brain, and to evaluate whether there was any effect after vaccination through bulk-RNA sequencing.
Results: After H&E, Masson, mast cells and Ki-67 staining analyses, there are no significant differences between tissues and organs in the vaccine group and the PBS group, and RNA-Seq did not show that the vaccine had any effect on immature mice.
Conclusion: COVID-19 inactivated vaccine is safe in immature mice.
期刊介绍：
The journal Immunopharmacology and Immunotoxicology is devoted to pre-clinical and clinical drug discovery and development targeting the immune system. Research related to the immunoregulatory effects of various compounds, including small-molecule drugs and biologics, on immunocompetent cells and immune responses, as well as the immunotoxicity exerted by xenobiotics and drugs. Only research that describe the mechanisms of specific compounds (not extracts) is of interest to the journal.
The journal will prioritise preclinical and clinical studies on immunotherapy of disorders such as chronic inflammation, allergy, autoimmunity, cancer etc. The effects of small-drugs, vaccines and biologics against central immunological targets as well as cell-based therapy, including dendritic cell therapy, T cell adoptive transfer and stem cell therapy, are topics of particular interest. Publications pointing towards potential new drug targets within the immune system or novel technology for immunopharmacological drug development are also welcome.
With an immunoscience focus on drug development, immunotherapy and toxicology, the journal will cover areas such as infection, allergy, inflammation, tumor immunology, degenerative disorders, immunodeficiencies, neurology, atherosclerosis and more.
Immunopharmacology and Immunotoxicology will accept original manuscripts, brief communications, commentaries, mini-reviews, reviews, clinical trials and clinical cases, on the condition that the results reported are based on original, clinical, or basic research that has not been published elsewhere in any journal in any language (except in abstract form relating to paper communicated to scientific meetings and symposiums).
