How effective is Gardasil against HPV?
The trials that led to approval of Gardasil 9 found it to be nearly 100\% effective in preventing cervical, vulvar, and vaginal infections and precancers caused by all seven cancer-causing HPV types (16, 18, 31, 33, 45, 52, and 58) that it targets (10).
What are the side effects of Gardasil?
The most common side effects include:
- pain, swelling, redness, itching, bruising, bleeding, and a lump where your child got the shot.
- headache.
- fever.
- nausea.
- dizziness.
How does the Gardasil vaccine work?
Gardasil works by stimulating the immune system to attack HPV types 6, 11, 16, and 18. Once Gardasil is administered, the body’s immune system recognizes the viral proteins in Gardasil as foreign, and develops antibodies against them, thus providing immunity from future infections.
What types of HPV does Gardasil protect against?
All three HPV vaccines protect against HPV types 16 and 18 that cause most HPV cancers. Since late 2016, only Gardasil-9 (9vHPV) is distributed in the United States. This vaccine protects against nine HPV types (6, 11, 16, 18, 31, 33, 45, 52, and 58).
How effective is the hepatitis vaccine?
A safe and effective vaccine that offers 98\% to 100\% protection against hepatitis B is available. Preventing hepatitis B infection averts the development of complications including chronic disease and liver cancer.
Is Gardasil a live vaccine?
The vaccine does not contain any live virus, or even killed virus or DNA from the virus, so it cannot cause cancer or other HPV-related illnesses. When the vaccine is given, the body makes antibodies in response to the protein to clear it from the body.
What type of vaccine is the Gardasil vaccine?
About HPV Vaccines 9-valent HPV vaccine (Gardasil-9 [23 pages] ) is a non-infectious recombinant vaccine prepared from the purified virus-like particles (VLPs) of the major capsid (L1) protein of HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58.
How is Gardasil vaccine made?
The HPV vaccine is made using a protein that resides on the surface of the virus. The protein is grown in the lab in yeast cells. Once the protein is grown, it assembles itself to look like the HPV virus; however, importantly, it does not contain HPV genetic material, so it can’t reproduce itself or cause illness.
What does Gardasil 4 protect against?
Gardasil is a vaccine, licensed for use in June 2006, by the FDA. It targets four strains of human papillomavirus (HPV) — HPV-6, 11, 16, and 18. HPV-16 and HPV-18 account for about 70\% of all cervical cancers. HPV-6 and -11 cause about 90\% of genital warts.
Which HPV strains are high risk?
The 14 most cancer-causing HPV types include types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68. Types 16 and HPV 18 are most commonly associated with development of cancer, together accounting for about 70\% of invasive cervical cancers. However, not all infections with HPV 16 or 18 do progress to cancer.
How is hepatitis B prevented?
Hepatitis B infection can be prevented by getting vaccine and HBIG (hepatitis B immune globulin) soon after coming into contact with the virus. Persons who have recently been exposed to HBV should get HBIG and vaccine as soon as possible and preferably within 24 hours, but not more than 2 weeks after the exposure.
