Final answer:
No, you do not need to be vaccinated again.
Step-by-step explanation:
The answer to the question is 2) No, you do not need to be vaccinated again.
Once vaccinated for HBV (Hepatitis B virus), the vaccine provides long-lasting protection and individuals do not typically need to be revaccinated. The vaccine stimulates the immune system to produce antibodies that protect against HBV infection.
It is important to note that individuals with certain medical conditions or on certain medications may have a compromised immune response and may require additional vaccinations to maintain protection.
