Human Papillomavirus (HPV) is a common virus that is spread through sexual contact. According to the Centers for Disease Control (CDC), it is one of the most common sexually transmitted diseases (STDs) in the country, with more than 20 million people currently infected and another 6.2 million contracting the virus each year. Every year, about 12,000 women are diagnosed with cervical cancer and almost 4,000 women die from this disease in the U.S. alone. The vaccine Gardasil was initially introduced to vaccinate girls before they become sexually active in order to prevent cervical cancer later in life. But reactions to this vaccine have reached levels that haven’t been seen before with other immunizations.
