Immunity
Active vs passive immunity
Antibodies tum khud banate ho, ya ready-made udhaar lete ho? Yahi ek sawaal active ko passive se alag karta hai.
Active immunity
Tumhara apna system antigen se milta hai — microbe ya vaccine — aur apne antibodies aur memory cells banata hai. Banne me slow, par lambe samay tak.
Passive immunity
Ready-made antibodies tumhe diye jaate hain — placenta se, maa ke doodh me, ya injected antiserum ke roop me. Turant protection, par kam samay, aur no memory.
Trap yeh hai
Speed vs durability se pata chal jaata hai. Active = tum banate ho, slow par lasting (memory ke saath). Passive = udhaar, turant par temporary (no memory). Tetanus antitoxin passive hai; tetanus vaccine active.
Ek quick check
Maa ke doodh se bachche ko mile antibodies bachche ko dete hain:
- AActive immunity
- BPassive immunity
