Thanks so much for taking the time to respond!

I was coming to the conclusion that there won't be a black and white conclusion..

Hep B looks like the easiest - how would a child contract this in any reasonable circumstance?

Luckily my wife is pretty based so no need to convince her. While not being able to trust, I feel the need to verify what I can.

I'll watch the videos today.

Questions I'm looking at:

- What is the disease to protect agains
- What are the chances of catching it
- What are the available vaccines
- How much protection do they give (initial + wear off)
- What are the safety studies (all seem short and shotty so far)
- How are they produced

Any other good ideas to add?
