In brief: Yes

If his post-procedure semen analysis negative, then there is no need for additional contraception.
While not 100% effective (the "act of god" pregnancy can still occur), if negative then there should be no worries.

In brief: Very reliable

If a vasectomy is performed correctly, there is no need for additional contraception because it is >99% effective.
He can go to his regular doctor for a semen analysis. If no viable sperm are seen on a sample, then you should not require additional contraception.

In brief: Yes

Once the post vasectomy semen is checked and confirmed to be 0, you can feel safe.

In brief: See urologist

A vasectomy is very reliable, and the ejaculation is tested afterwards for semen.
But for your peace of mind, your husband could visit his urologist for testing.
