Hypersensitivity Reaction (Type I-IV)

I am making videos related to science (Microbiology, Biochemistry Haematology etc.) in Nepali medium.
I think it will help our nepali students to learn and understand the subject matter easily.
If you think it is helpfull for you and your friends, please like, share, comment and subscribe my Youtube channel.
Thank you for your love, care and support.
