Awesome video!! However, between the time stamps 5:33 - 5:45, you said "Now the peak of the reaction, occurs 48 hrs after the *FIRST EXPOSURE*"... this confused me with regards to the event timeline of the disease because the textbook mentions it occurs in that timeline in an already sensitized individual, which would suggest that "the peak of the reaction, occurs 48 hrs after the *SECOND EXPOSURE*", not the FIRST. Would you please look into it?
Perfect video! Thank you so much! I have some questions. So does this mean that in the tuberculosis mycobacteria infection, we have T cells that activate at the lung level after 48 hours at the most? And then we have the manifestation of the disease? Moreover, in these hypersensitivity reactions there is always a need for a first sensitization?
Could you please help me by sharing my contents with your friends group/ college group. I put huge efforts in making these videos but unfortunately not a lot of people are watching this.

But is delayed type of hypersensitivity is similar to type 1 hypersensitivity as allergy I was not clear about the delayed one, if you could please explain...
Phenotype wise it looks similar but the effector mechanisms are different allergies are igE dependent but type 4 hypersensitivity involves lymphocytes but not antibodies

Im trying to understand where the immunity comes from. My mother and daughter are immune to poison ivy and i am very much NOT lol
how many days or months does one suffer after reaction to antibiotics? is this life threatining with other complications?
In majority of the cases it's not life threatning. But please consult a doctor because it is context dependent.
Why in acute infection skin test will be negative?
Is life-threatening
?
In most cases no
Thank you ❤
