Adult Hepatitis B Vaccine

If you are sourcing Adult Hepatitis B Vaccine and require a safe and effective vaccine, you can choose AIM Honesty Biopharmaceutical Co., Ltd. as your manufacturer. We are a Chinese company with extensive experience and comprehensive production and R&D capabilities. For this vaccine, we use small-dose packaging, resulting in shorter injection and pain duration, and a better vaccination experience.

Why Do Adults Need to Be Vaccinated Against Hepatitis B?

1. To prevent serious and potentially fatal liver disease

• Acute hepatitis B can cause fever, jaundice, and liver failure; 5-10% of cases develop into chronic infection and may progress to cirrhosis or hepatocellular carcinoma.
• Hepatitis B is the leading cause of primary liver cancer globally; vaccination is the only approved vaccine that can prevent this cancer.

2. Many adults missed previous vaccination programs and remain unprotected

• Between 2011-2014, only about 28% of high-risk adults in the US had immunization records; a universal adult catch-up vaccination program is needed to bridge this gap.

3. To reduce community transmission and healthcare costs

• Universal vaccination can create herd immunity, reducing acute infection rates by half between 2000-2014.
• Preventing one chronic carrier avoids the lifelong costs of liver disease management, cancer treatment, and lost productivity.

4. Easy to integrate into routine healthcare

• We believe pre-vaccination testing should be encouraged but should not delay vaccination; routine medical orders allow nurses/pharmacists to administer the vaccine to eligible adults on the spot.

As a leading supplier in the industry, AIM Vaccine recommends that all adults be vaccinated against Hepatitis B. According to the CDC/ACIP 2022 guidelines, all adults aged 19-59, regardless of risk, should receive 2 or 3 doses of the vaccine; adults aged 60 and older should also be vaccinated if they have any risk factors or simply wish to be protected.

Adult Hepatitis B vaccination is no longer limited to high-risk groups. All adults under 60, and any adult over 60 who requests it, should complete the full course of vaccination to eliminate personal risk and help drive the elimination of hepatitis B.

Our vaccine is safe, effective, and long-lasting; 90% of adults develop protective antibody levels after completing the full course of vaccination; immunity lasts for 20-30 years or more, and booster shots are rarely needed. Most adverse reactions after vaccination are mild (pain at the injection site); severe reactions are extremely rare.

Vaccination Precautions

(1) The following patients should use this vaccine with caution: those with a family history or personal history of convulsions, chronic diseases, a history of epilepsy, or allergic constitution.

(2) It is unclear whether this vaccine can prevent hepatitis B in patients who are in the incubation period of hepatitis B.

(3) Intradermal and gluteal intramuscular injections should be avoided as they do not achieve optimal immune effect;

However, because intramuscular injection may cause bleeding in patients with thrombocytopenia and hemorrhagic diseases, subcutaneous injection may be used in special circumstances.

This product must not be administered intravenously under any circumstances.

(4) Shake well before injection; the vaccine container should be opened and used immediately.

(5) Do not use Adult Hepatitis B Vaccine if there are undissolved clots, the vaccine container is broken, the label is unclear, or the vaccine has expired.

(6) When scheduling vaccinations, epinephrine and other medications should be available for emergency use in case of a severe allergic reaction.

Vaccine recipients should be observed on-site for at least 30 minutes after vaccination.

(7) Do not freeze the vaccine.

(8) Patients who experience fever, convulsions, or other abnormal conditions after the first injection should generally not receive a second injection.

For infants whose mothers are HBsAg and/or HBeAg positive, the doctor should administer the second and third injections according to the instructions.

(9) Use in special populations:

Pregnant women: There are currently no relevant research data on this population. The benefits and risks should be carefully weighed before deciding whether to use this product.

(10) Drug interactions:

Simultaneous use with other vaccines: Clinical studies on the impact of simultaneous (first, second, or concurrent) vaccination with other vaccines on the immunogenicity of this vaccine have not yet been conducted. There is currently no data to evaluate the effects of using this product simultaneously with other vaccines.

Immunosuppressive drugs: Including immunosuppressants, chemotherapy drugs, antimetabolites, alkylating agents, cytotoxic drugs, and corticosteroids, these drugs may reduce the body's immune response to this vaccine.

Patients undergoing treatment: It is recommended to consult a doctor to avoid possible drug interactions.
