غیر فعال استثنیٰ میں آپ کے جسم کو تیار کرنے کے بجائے کسی بیماری میں پہلے سے تیار کردہ اینٹی باڈیز حاصل کرنا شامل ہوتا ہے ، فوری لیکن قلیل المدتی تحفظ فراہم کرتا ہے۔ مندرجہ ذیل میں سے کون سا پیدائش سے پہلے غیر فعال استثنیٰ کا ذریعہ ہے؟

This protection is temporary.

It helps the baby fight infections until its own immune system develops.
