Vaccines and the Immune Response: How Vaccines Work 

This 3 and half minute video feels like I've been sitting in class for a whole day

I feel like a 5 year old walking into an adult conversation

The human body is amazing!

I'll keep this video on my "Watch-Later" list until I go get my PhD in medicine! ... I'll be back!

Some people may find that reading the information is easier for them. Influenza vaccines work by using inactivated viral particles containing hemagglutinin h and neuraminidase NA(sub-Varian particles) to trigger an immune response by injecting it into the muscle. Immune cells such as macrophages, T and B cells will break the hemagglutinin into small components by ingesting it(macrophage phagocytosis). On the surface of the macrophage, the hemagglutinin antibody and the major histocompatibility complex(MHC t-cells) will appear. Now the MHC t-cells can bind to antigens associated with the MHC. T-cells become either cytotoxic t-cells, suppressor t-cells, or helper t-cells. Helper t-cells have hemagglutinin receptors, can produce antibody creation, and help with memory b-cell activation. B-cells can ingest hemagglutinin without MHC. After ingestion, it then presents the hemagglutinin along with the MHC on its surface. If an active B expressing the antigen MHC and T-cells interact, the T-cell secretes lymphokines, which will differentiate the b-cell into either a memory b-cell or a plasma cell. Plasma cells make hemagglutinin antibodies specific to the strain in the vaccine. Memory b-cells help fight against future infections by activating the immune response. Aerosol droplets containing live influenza droplets try to infect the nasopharyngeal epithelial layer of the body. The antibodies either block or diminish the severity of the virus.

Went here to get an idea how vaccine works. Ended up even more confused 😞

For everyone saying that thought this was really complicated, consider this: A virus (in most cases) has no life or DNA of its own. It has to replicate by using a living thing’s DNA (in the nucleus of its cells) as a host. However the virus does have its own RNA that uses that DNA for its own purposes. The vaccine uses a modified form of the RNA that your cells/DNA mark and use in a way that get all of the cells in your body to clock the virus as a threat and smash it at every stage. It an awesome video but I can see how people might get lost in the details. Hope that helps.

As a computer science student, I did not understand a thing

I’m surprised I actually understand this 💀 yall, for everyone who’s confused I recommend watching cells at work. It helped me a lot and it’s fun to watch :)

Pretty simple its like training ur cells to recognize the enemy if needed

It is the best concise animation explaining interactions involved in vaccination

Who is here for the Coronavirus?

_IMPECCABLE TIMING!_

Thank you so much! I had previously watched another video which I found too vague and general. This video was clear and informative, and I appreciate the scientific detail.

Sounds great! 👍🏾

I am glad that I am not the only one too stupid to understand this video

The narrator nailed the script!

Goddamn. I need a course in micro biology just to understand this

Can we get English please?

can we have a concept map for this?

அருமை யான பதிவு, தெளிவான விளக்கம் 🙏🙏🙏

Is there an English version of this video?

Valuable for my extension services---thanks ! :-)

Sir.. Can I know how's the process on production of killed vaccine but still retains their native nature?

The timing and description of this video

Alright, I will come back with a PHD to understand it.

2:32 antibodies produce hemagglutinin antibodies 1:38 t helper cells functions

Can someone please translate this to the English language? Thank you in advance.

Thanks a lot.

i am a father to 5 and my kids arent vaccinated edit:4 edit:2 kids

Amazing video👨‍🔬

Watched this after i got my vacc. Couldn’t process a single thing. Thanks.

It’s kinda crazy what your body dose on a everyday bases

My question is if we come in contact with immune response like fever ,chill, fatigue can we get covid positive report in rtpcr

I’ve watched this to help me better understand but feels like your brain been eaten alive🤣🤣🤣🤣

wooh man my brain cells went on hibernation after watching this video :)

THANKS A LOT iT´S INTERESTING VIDEO. yOU CAN HELP FORMULING QUESTIONS WITH THEIR ANSWERS.

I wrote "what exactly is a vaccine" to fully know how it works, instead of watching video saying "vaccine is weakened virus". I regret doing it.

Suddenly suffocates watching this

So if reactive lymphocytes showed in my blood work 10 days post vaccine, does it mean my immune response is working?

Amazing...

Cells at work helps me to understand this 🤠😸

Good animation

Showed this to my 8 year old, who got her flu shot yesterday.

Great video for an engineer too 🙂

Fascinating

Okay thanks for this I learned a lot.. But I'm scared if i have a after life what if i become microorganisms?hshshsh

Couldn't understand still.May be that's why it's really so complex to built vaccine.🤔 Note: I got more than 90% in biology in my 10th.

Exllent please do more vedios like this class 12 questions pleaae

My brain hurts💀💀

Now I remember why I decided not to go to med school.

This video is for scientists 🥼

I understand about this randomly....but ....I have idea about vaccine.....after see this video

great video, thank you very much for making this.

Cool.

Good

Chinese sinovac vaccine is inactivated..

To IMAGINE that all these wheels within wheels inside our bodies two hundred thousand years ago, along with sight, hearing, smell & touch the nerve of anyone with such a wild imagination.

I didnt think B cells were found in the blood?

#CoronaVirus vaccine is possible ? HIV vaccine is possible this way ?

The puppy was a dog, but the industry my friends... that was a revolution.

Take notes class there will be a quiz

I took Vaccine I had 102 fever with cold and bodypain.....people say your immune system is weak that's the reason ur facing side effects is this true ?

Click the caption. But no English subtitles..😞😞

Is this the exact idea of vaccine?

Am bio tech student..it's easy to understand me

Can the vaccinated still spread flu virus after being infected?

To understand this video you need to study immunology first,this is not for starters

Thanks !

Roitt and kuby in a flash

GOODLUCK TO PEOPLE WHO GOT VACCINE IN THEIR BODIES.😚

Buy saline nasal wash and wash after coming home from outside during these corona virus days

OMG I Feel Like,I just understood the First 30 Seconds after that my Brain was just hearing funny sounds. I will Tag this Video for Anotehr session 20yrs from Now. What i can say is the HUman Body is Amazing.

What??

Damn I only understand like the first few seconds, after that I'm in a blackhole.

Who are vaccinations ??

OK explain this to me like im 5 years old.

Just a push and a shove from something going wrong. Like rogue cells !

Who is going to take vaccine and watching this what animation will then happen to the body ?

I understand nothing, very difficult terms used.

It is very very dangerous the viruses very very dangerous

I'll just let my immune system that God gave me do it. # Life long immunity

Oh wow,who would have known.😅

Whos here in corona??

Humans are the worst creatures to walk on this planet .

Why do people think vaccines are bad? . A vaccine sounds helpful to me.

Okay........I got that🥴

Whos here after the rona vaccine coming in December?

insert cells at work comment here

vaccine vs coronavirus

I'm still not talking it

🧐 Say what now? 😅

T-cell B-cell...⌛

Video incomprehensible

I only searched this cuz of covid

Today I got a vaccine 🤗🤗🤗❤😘

This is why you should take science group 😅.

Problem is, flu virus keeps changing and evolving.. so vaccine is obsolete. Unless you got that specific virus which is about a year old.

After the Vaccine the Body will feel weird and weak
