the correct answer is Jenner devoted more time to the vaccine than to his private practice.
Explanation:
Edward Jenner was the physician who developed the vaccine for the deadly smallpox disease, which killed approximately 300 million people in the 20th century alone!
He was an advocate of vaccination and tried to popularize the practice of vaccination.
James Phipps was the 1st person to be given the small fox vaccine by Jenner, he was an 8 year old boy.
