- Vaccinations are injections of antigens into the body. Once the antigens enter the blood, they circulate along with other cells, such B and T cells. B and T cells are white blood cells that help the body defend itself against foreign invaders. As the antigens invade the body's tissues, they attract the attention of macrophages. Macrophages are non-specific scavengers, which in this case, engulf the antigens. The macrophages then signal the T cells that antigens are invading. The killer-type of T cells respond by attacking the invading antigen. Finally, the suppressor T cells stop the attack. After a vaccination, the body will have a memory of an encounter with a potentially dangerous invader for a period of time, and hopefully have a better ability to fight it off if ever exposed to it again in greater numbers. A vaccine is a biological preparation that provides active acquired immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing micro-organism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as a threat, destroy it, and keep a record of it, so that the immune system can more easily recognize and destroy any of these micro-organisms that it later encounters. Vaccines can be prophylactic (example: to prevent or ameliorate the effects of a future infection by any natural or "wild" pathogen), or therapeutic (e.g., vaccines against cancer are also being investigated). The administration of vaccines is called vaccination. The effectiveness of vaccination has been widely studied and verified; for example, the influenza vaccine, the HPV vaccine, and the chicken pox vaccine. Vaccination is the most effective method of preventing infectious diseases; widespread immunity due to vaccination is largely responsible for the worldwide eradication of smallpox and the restriction of diseases such as polio, measles, and tetanus from much of the world. The World Health Organization (WHO) reports that licensed vaccines are currently available to prevent or contribute to the prevention and control of twenty-five infections.
Vaccine Basics How Vaccines Work What is Immunity? When disease germs enter your body, they start to reproduce. Your immune system recognizes these germs as foreign invaders and responds by making proteins called antibodies. These antibodies’ first job is to help destroy the germs that are making you sick. They can’t act fast enough to prevent you from becoming sick, but by eliminating the attacking germs, antibodies help you to get well. The antibodies’ second job is to protect you from future infections. They remain in your bloodstream, and if the same germs ever try to infect you again - even after many years - they will come to your defense. Only now that they are experienced at fighting these particular germs, they can destroy them before they have a chance to make you sick. This is immunity. It is why most people get diseases like measles or chickenpox only once, even though they might be exposed many times during their lifetime. Vaccines to the Rescue. Vaccines offer a solution to this problem. They help you develop immunity without getting sick first.
Vaccines are made from the same germs (or parts of them) that cause disease; for example, polio vaccine is made from polio virus. But the germs in vaccines are either killed or weakened so they won’t make you sick. Vaccines containing these weakened or killed germs are introduced into your body, usually by injection. Your immune system reacts to the vaccine the same as it would if it were being invaded by the disease - by making antibodies. The antibodies destroy the vaccine germs just as they would the disease germs - like a training exercise. Then they stay in your body, giving you immunity. If you are ever exposed to the real disease, the antibodies are there to protect you.
Why are vaccinations important?
Vaccinations protect your child against serious diseases by stimulating the immune system to create antibodies against certain bacteria or viruses.
What diseases do vaccines protect against?
Immunizing your baby with vaccines protects against serious diseases like measles, whooping cough, polio, meningococcal disease, tetanus, rotavirus, hepatitis A, hepatitis B, chickenpox, influenza, and more.
I don’t know anybody who has had these diseases. Why does my baby need these vaccines?
While a few of these diseases have virtually disappeared because of vaccination, reported cases of people with diseases like measles and whooping cough have been on the increase lately. Even if some diseases do completely disappear in the U.S., they are common in other parts of the world and are just a plane ride away.
This video feels so 90s
No wonder it felt so familiar and comfortable.
Feels like health class. Hahaha
🎉👍
And so relevant for 2021 😂
It is made from there
2022🤚🏻
2021 after covid-19 vaccine done
☝😬 same
although the most commonly used vaccines in the past stay locally in the injection site, the experimental covid vaccines do not; which is why there have been a considerable increase in side effects from these vaccines alone.
Oh look! Its the Power Rangers!
Me before this video : doctor injects good virus to fight against the bad virus
Me after this video : ahhh so it was my immune system fighting against virus
I got one part of it in January and the last part today I was just curious to see what happens when it goes into your skin because my arm hurts a bit
Research should of been done before getting shot. Good luck.
Oh that is god nice and I'm ready to vaccine😁
Ye vaccine kam Cadbary gems jyda lg rhi hain...
I just got vaccinated today.
Once i get injection for fever. Bt i have a pain til after more than one week, can u help me to get remedy
You might get pain in the location of where the vaccination was injected and some proximal lymph nodes which expand since they are full of dividing lymphocytes. The pain will subside in a week or so, if it persists, or if there is irritation, redness, swelling, or fever from at the site of the injection go see your doctor to make sure that everything is in order.
I got vaccinated because i got bitten by a dog... Is there any *side affects* in this situation?
Always side effects to every vaccine. Please read the inserts.
@@kristinmarie1749 what?
@@RoyceFlamir it depends on what vaccine you got? Different vaccines have different adverse reactions. You can find the inserts by googling them and then downloading the pdf or you can go to this website vactruth.com/vaccine-inserts-human/ and scroll until you find the name of your vaccine then you download it and read. I am assuming you were giving the Dtap, which is a 3 in 1, for the tetanus portion of the vaccine. Dtap is top 3 most dangerous vaccine, especially for babies and children. I have know several babies who never woke up after their 4 month shots.
Royce Flamir i usually get a fever
*Me watching when i was vaccinated yesterday*
I came to learn how injections works
Amazing useful explain and easy to understand-
also i didnt know this vids was 5years ago
Who's watching this 2021?
HAHAH me idle
me and persons who Wondering how covid vaccine works
2022
Me before this video : doctor injects good virus to fight against the bad virus
Me after this video : ahhh so it was my immune system fighting against virus
i was curious
Thank you this helped a lot with my science test tomorrow
I thought it was phonepe logo which is moving inside..
I had a polio and meningitis vaccination today at school I just wanted to know what was in it
But but it was posted 5 years ago how did u know about covid
COVID isn’t the only disease ya know
how long does cat vaccine worke in human body ?
🇳🇵
H
Work? Work in the human body. BWAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA what utter nonsense!
^^^ and here ladies and gentlemen is a good example of what you believe if you aren't educated
I dumb
Fiver😥😥😥
Sad
@@eula4241 💆♂️💆♂️💆♂️
please can you tell them all the nasty vaccine ingredients??!
I'm sorry you uneducated fuck. Vaccines don't harm you at all, pretty much you want the worst for our kids and all of humanity? The vaccines don't have nasty ingredients, they only contain dead or extremely weakened viruses and bacteria. Go learn more you anti vaccinators!
Very good Question. Another Question why are vaccinated people still coming down with the disease they were vaccinated against? Can these ill Vaccinated people be actually spreading the disease? Are Babies actually getting Whooping Cough from their older vaccinated siblings or relatives that are told to get vaccinated before coming in contact with the baby to protect them? Does Antibodies actually mean protection? Has this actually been proven? If so how and when was it proven? How is natural herd immunity different to herd immunity through Vaccines. At what % is Herd Immunity through vaccines achieved? Do they know what this % is? How do they work this out? Why does this % that they state is needed keep changing?
Why can't we ask questions, even just one question without someone viciously with usually vulgar, emotional irrational emotions and anger attack us and keep coming up with this term Anti vax? It seems that it is ok for a consumer to ask questions about most other products they are researching but you cannot do this when researching vaccines. Especially when all other products the company that produced it can be sued if the product has been shown to be defective, and has caused you harm, but the consumer does not have this legal right with vaccines as the Pharmaceutical companies are not liable. Why is this? Look into it and you find out that you need to ask plenty of questions because the pit of unanswered questions get bigger the more you dig. Blind faith is not for me.
well if you really want to know. do the fuckign research. or trust the scientists who did it for you lazy fuck.
Jennifer Maskiell I...I have no words, wait! I DO!
CRAAAAAAAZY!
that is not an answer to the question you were asked, it was a foolish emotional reaction that is obvious to everyone : you are hurting other people by spreading lies!
I get 2 shots tomorrow and I am nervous
I GOT 3
I got 2.
