WHAT IS VACCINE?
A vaccine is a medical product that trains your body’s immune system to recognize and fight specific germs (like viruses or bacteria) without causing the disease itself.
Here’s how it works in simple terms:
A vaccine usually contains a harmless part of the germ (like a protein or a weakened/killed version of it).
When the vaccine enters your body, your immune system reacts as if the real germ has invaded.
Your body makes antibodies and memory immune cells.
Later, if you’re exposed to the actual germ, your body quickly recognizes and destroys it—preventing you from getting sick or making the illness much milder.
👉 In short: A vaccine is like a “practice run” for your immune system, preparing it to defend you against real infections.
APA ITU VAKSIN?
Vaksin ialah produk perubatan yang melatih sistem imun badan supaya dapat mengenal pasti dan melawan kuman
tertentu (seperti virus atau bakteria) tanpa menyebabkan penyakit sebenar.
Cara vaksin berfungsi:
Vaksin mengandungi bahagian kuman yang tidak berbahaya (contohnya protein, atau kuman yang telah
dilemahkan/dimatikan).
Apabila vaksin masuk ke dalam badan, sistem imun bertindak balas seolah-olah kuman sebenar telah menyerang.
Badan menghasilkan antibodi dan sel memori imun.
Apabila terdedah kepada kuman sebenar kemudian hari, badan dapat mengenal pasti dan memusnahkannya
dengan cepat—sama ada mencegah jangkitan atau mengurangkan tahap keseriusan penyakit.
👉 Ringkasnya: Vaksin ialah “latihan awal” untuk sistem imun supaya bersedia melawan jangkitan sebenar.
