Benrubi has practiced medicine for more than three decades, but his main passion nowadays is educating people on the importance of getting the HPV vaccine. “A lot of people are not aware of the importance of the HPV vaccine, so lack of knowledge is also an important factor. AdThe CDC also says the HPV vaccine does not cause HPV infection or cancer. “Now that 30-year-old could have been vaccinated 15 years ago when the HPV vaccine came out, and she would not have had to die,” he said.
