First Anti-cancer Vaccine
Hepatitis B vaccine prevents hepatitis B disease and its serious consequences like hepatocellular carcinoma (liver cancer). Therefore, this is the first anti-cancer vaccine.
Safe and Effective
Medical, scientific and public health communities strongly endorse using hepatitis B vaccine as a safe and effective way to prevent disease and death.
Scientific data show that hepatitis B vaccines are very safe for infants, children, and adults.
There is no confirmed evidence which indicates that hepatitis B vaccine can cause chronic illnesses.
To assure a high standard of safety with vaccines, several federal agencies continually assess and research possible or potential health effects that could be associated with vaccines.
Contraindications to Vaccine
A serious allergic reaction to a prior dose of hepatitis B vaccine or a vaccine component is a contraindication to further doses of hepatitis b vaccine. The recombinant vaccines that are licensed for use in the United States are synthesized by Saccharomyces cerevisiae (common bakers' yeast), into which a plasmid containing the gene for HBsAg has been inserted. Purified HBsAg is obtained by lysing the yeast cells and separating HBsAg from the yeast components by biochemical and biophysical techniques. Persons allergic to yeast should not be vaccinated with vaccines containing yeast.
Vaccine Schedule
Printable childhood and adolescent immunization schedules: National Immunization Program, CDC
Adult Immunization Schedule: National Immunization Program, CDC
If the vaccination series is interrupted after the first dose, the second dose should be administered as soon as possible. The second and third doses should be separated by an interval of at least 2 months. If only the third dose is delayed, it should be administered when convenient.
Recommended dosages and schedules of hepatitis B vaccines
Booster Doses
Current data show that vaccine-induced hepatitis B surface antibody (anti-HBs) levels may decline over time; however, immune memory (anamnestic anti-HBs response) remains intact indefinitely following immunization. Persons with declining antibody levels are still protected against clinical illness and chronic disease.
For health care workers with normal immune status who have demonstrated an anti-HBs response following vaccination, booster doses of vaccine are not recommended nor is periodic anti-HBs testing.
Post-vaccination Testing
After routine vaccination of infants, children, adolescents, or adults post-vaccination testing for adequate antibody response is not necessary.
Post-vaccination testing IS recommended for persons whose medical management will depend on knowledge of their immune status.
This includes persons who:
are immunocompromised (e.g., hemodialysis patients)
received the vaccine in the buttock
are infants born to HBsAg (hepatitis B surface antigen)-positive mothers
are healthcare workers who have contact with blood
are sex partners of persons with chronic hepatitis B virus infection
Post-vaccination testing should be completed 1-2 months after the third vaccine dose for results to be meaningful. A protective antibody response is 10 or more milliinternational units (>=10mIU/mL).
Adverse Events
Case reports of unusual illnesses following vaccines are most often related to other causes and not related to a vaccine. Whenever large number of vaccines are given, some adverse events will occur coincidentally after vaccination and be falsely attributed to the vaccine.
Anyone believing they have had a possible reaction or adverse health effect from a vaccine should report it to their health care provider. The Vaccine Adverse Events Reporting System (1-800-822-7967) receives reports from health care providers and others about vaccine side effects.

whats hbv??
Take this question to a doctor. There is a lot more under this question than can be answered in a group like this. Yes, the HBV vaccine is a series of three shots. You should also realize that there is no "cure" for a virus and that there are many strains of this particular virus. Even if you have been vaccinated with all three shots, there is still a possbility that you can contract HBV by having unprotected sex with one who is infected with HBV. Also, using prtection does not guarantee that you will not contract the virus.
I take it you mean HPV?
The new HPV vaccine protects against the two HPV types that cause most (70%) cervical cancers (types 16 and 18), and the two HPV types that cause most (90%) genital warts (types 6 and 11).
Because the vaccine does not protect against all types of HPV, it will NOT prevent all cases of cervical cancer or genital warts. About 30% of cervical cancers will not be prevented by the vaccine, so it will be important for women to continue getting screened for cervical cancer (regular Pap tests). Also, the vaccine does not prevent about 10% of genital warts—nor will it prevent other STIs— so it will still be important for sexually active adults to reduce exposure to HPV and other STIs.
In other words, you still need to use condoms.
