One question miss ! We went through graphs on artificial passive and natural passive, natural active but we didn’t go throught artificial active immunity graph. Can u please share its graph—would help alot !! THANKYOU ❤❤

Hi! Great video! I had two questions . 1) When antibodies are injected into our bodies, why doesn't the body see it as a non -self antigen ? 2) What happens to antibodies after the first immune response ? Do they die, or do they stay in the blood like memory cells do?

Hi miss beh is eradication of diseases, vaccination of cholera and malaria included in syllabus of 2024 or is it extra information ?

[pansherbalochistan]

Can someone recommend me a good chem As channel with notes

[DashboundAdventures]

a little confusion, as you said memory cells are not produced in passive immunity. how come? what if Igs/antibodies are given then it makes sense that it will provide quick immunity and B-cells wont be activated and thus memory cells wont be produced. what if antigens are given (instead of Igs) in passive immunity then these antigens will be taken up by APCs then memory cells should be produced. right?

[legacybuster]

can u please share me the slides that you use for the videos, that would be really helpfull

[mudasserkhan]

Are we required to know vaccination against different diseases or did you explain them for informational purposes?

[alinaasghar]

what is the difference between active and passive artificial immunity?

[fatimaazizbaghpati]

Hi herd immunity mass vaccination effective and ineffective vaccines aren't mentioned in current syllabus.
Is it for information purpose only in the video??

[saviaidres]

Is measles and small pox included for may june 2022?

[fareedsohail]

Why do some vaccines have long term immunity and why some have short term immunity even though both are introduced by a antigen?
And at 8:53 in passive artificial immunity it says that antigens are introduced via injection, so if antigen are introduced why there is not a immunity response and why does not it has long term immunity bcz as it is written that it is introduced in body by antigen?

if a person gets his 1st dose “Inactivated” vaccine, and then he tested positive covid at the 13th day after taking the jab. has this person got “Natural Immunity”
