Edward Jenner, known for developing the smallpox vaccine, faced criticism for his lack of rigorous scientific methodology in his experiments. His initial vaccination trial, which involved inoculating a young boy with cowpox, was not conducted under controlled conditions, leading to questions about the validity and reproducibility of his results. Additionally, Jenner did not fully understand the mechanisms of immunity, which later raised ethical concerns regarding the safety and efficacy of his approach. Despite these shortcomings, his work laid the foundation for modern vaccination practices.
