Subcutaneous injection of the COVID-19 vaccines may reduce the adverse post-vaccination effects, such as fatigue, while still providing similar immune-system responses, according to a study in mice. Despite their high efficacy against SARS-CoV-2, mRNA-based COVID-19 vaccines are associated with adverse post-vaccination effects, such as fatigue, the researchers said. Experiments in mice suggest that switching the vaccine injection strategy could potentially ease such adverse effects. However, the molecular underpinnings of adverse post-vaccination effects have been unclear, they said. However, subcutaneous injection did not appear to compromise the protective effects of vaccination, the researchers added.
