I got the shingles vaccine 5 years ago. Do I need to get it again?

It's the change of seasons and my body is starting to feel a bit shaky.

Have you ever heard of shingles?

I received a shingles vaccine once about five years ago, as I heard it's extremely painful and has scary complications. Recently, I've heard from people around me that I need to get vaccinated again, so I'm concerned and asking. I'm wondering if it's a good idea to get vaccinated again, and which vaccine will provide long-term immunity and long-term protection.

[Question]

1. As my friends said, I got the vaccine 5 years ago. Do I need to get it again now?
Did you all get it right?

2. I want to get the vaccine that will last the longest. What is the most effective vaccine and which one should I get?
I am curious about the interval between vaccinations and how long the preventive effect can be expected to last.

So, considering both the duration and the post-herpetic effect, I'd like to hear expert advice on which vaccine is the wisest choice.

I have a lot of questions
thank you
