Vaccine that targets 9 strains of HPV boosts cancer protection, study says
from Los Angeles Times
When it comes to HPV vaccines, more protection is better. A new version of the vaccine that fights nine strains of human papillomavirus offered greater cancer protection for women than the earlier one that targets only four, researchers reported in the
New England Journal of Medicine
. A multinational study involving thousands of women found that the nonavalent vaccine worked as well as the original vaccine at preventing infections caused by HPV-16 and HPV-18. Together, these strains are responsible for 70 percent of all cases of cervical cancer.
