Vitamin B9 (Folate) deficiency can lead to neural tube defect (NTD) and the main source of it is green vegetables. That's why any woman who plans on getting pregnant should consume sufficient amounts of B9 because the neural tube closes 27 days after conception meaning before a woman even knows she's pregnant!

The vitamin deficiency most closely associated with neural tube defects is the B vitamin, folic acid (or folate). Supplementation with Folic Acid 400 mcg/day (up to 1,000 mcg or 1 mg per day) for 6-8 weeks before pregnancy (and preferably throughout pregnancy) is associated with a roughly 50% reduction (30-70%) in the risk of having a baby with a neural tube defect (such as spina bifida).

Though it cannot be prevented completely, the chances can be reduced by about 75% by the woman taking folic acid supplements at least 3 months prior to becoming pregnant and then continuing them through at least the first trimester of pregnancy.

Do condoms cause birth defects?

Absolutely not. Condoms are intended to prevent pregnancy (and transmittal of diseases). If they fail as a contraceptive, there is no indication that they have any effect on the pregnancy themselves. In fact, if they fail to prevent a pregnancy they may still act to prevent disease - which can frequently be the cause of birth illnesses or problems. Hence if anything, condoms act to prevent defects.

What is the vaccine for birth defects?

There is no vaccine that will prevent birth defects. Spina Bifida and other neural tube defects (a specific type of birth defects) can be prevented by consuming adequate amounts of folic acid in the diet in the first trimester of pregnancy. Other types of birth defects may be prevented in other ways, so it is best to ask your doctor for advice if you are thinking about becoming pregnant.
