This is based on the preliminary results of the first study to test the effectiveness of mix-and-match vaccines, also known as "heterologous dosing". The study is being conducted by researchers at the University of Oxford and the National Immunisation Schedule Evaluation Consortium (Nisec). According to the results, chills, headaches, feverishness, and muscle pain were reported more frequently among participants who received the mixed doses. The authors indicated that further studies will evaluate the pairing of the Covid vaccines by Moderna and Novavax. “[These additional trials] are crucial to informing the appropriateness of mixed Covid-19 vaccine schedules,” the authors wrote.
