Based on the information provided, there are two main types of hepatitis A vaccines: the single-antigen vaccine and the combination vaccine.
Understanding Hepatitis A Vaccines
When considering protection against Hepatitis A, you generally have two vaccine options available. These options offer protection in slightly different ways, depending on your needs and age.
Single-Antigen Hepatitis A Vaccine
- This type of vaccine is designed specifically to protect against Hepatitis A infection.
- It is typically given as a series of shots.
Combination Hepatitis A and Hepatitis B Vaccine
- This vaccine offers protection against both Hepatitis A and Hepatitis B infections.
- A key point from the reference is that this combination vaccine can only be received if you are 18 years or older.
Choosing the right vaccine depends on individual health needs, age, and whether protection against Hepatitis B is also desired or required. Always consult with a healthcare professional to determine the most appropriate vaccine for your situation.
Here's a quick summary of the two types:
| Vaccine Type | Protects Against | Age Restriction |
|---|---|---|
| Single-Antigen Hepatitis A | Hepatitis A | Generally none specified |
| Combination Hepatitis A & B | Hepatitis A & Hepatitis B | 18 years or older |
Remember, the reference specifically mentions that there are two types: single-antigen and combination, and outlines their protective scope and the age restriction for the combination form.
