This is a standard, noninvasive echocardiogram. A technician (sonographer) spreads gel on your chest and then presses a device known as a transducer firmly against your skin, aiming an ultrasound beam through your chest to your heart. The transducer records the sound wave echoes from your heart.
Why does my child need HPV vaccine? HPV vaccine is important because it protects against cancers caused by human papillomavirus (HPV) infection. HPV is a very common virus; nearly 80 million peopleâabout one in fourâare currently infected in the United States. About 14 million people, including teens, become infected with HPV each year.
HPV vaccination is also effective in males to protect their partners from HPV infections, as well as themselves from anal cancer and genital warts, and possibly other HPV associated cancers. Two vaccines have market approval in many countries as of 2014 (called Gardasil and Cervarix in the US).urrent preventive vaccines protect against the two HPV types (16 and 18) that cause about 70% of cervical cancers worldwide. Because of the distribution of HPV types associated with cervical cancer, the vaccines are likely to be most effective in Asia, Europe and North America.
