4-3 Infection and Response


How does the HPV vaccination decrease the number of girls who get cervical cancer? (The vaccination injections inactive or dead forms of HPV to stimulate the white blood cells to produce antibodies aainst HPV. This also then produces memory cells for the HPV as an antigen is produced. This means that, if infected, the antibodies will be produced faster against HPV and stop the infection. Girls who have had the vaccine are less likely to get cervical cancer and it lowers the chances the virus will spread).

When a mosquito passes the virus from person to person what type of organism is it in this case? (vector)

- A vector is something that transmits infectious pathogens to other organisms.
