After the offering of Biochemistry, Immunity, and Infections II last spring, Biochemistry, Immunity, and Infections I was offered again on 3 and 6 April 2024, with eight motivated students completing the course successfully. It was the third offering of the course with the name ‘Biochemistry, Immunity, and Infections I‘ (the course was named as ‘Biochemistry and Infections‘). In spite of the intellectually challenging nature, the courses were still offered every other year, suggesting that many students were interested in immunology. Hopefully, some of them will become future immunologist and microbiologist!
