Memory cells:
Memory cells help us mount quicker responses to antigens we have previously encountered.
Revised:
When you body first encounters a virus, the immune system does not know the type of white blood cell that can destroy the virus. Thus, giving the virus enough time to take over. When you get a vaccine, it is basically a virus that is too weak to do any harm. Which means, a vaccine puts a type of virus dummy in your body. This way, your body can take time to train against this new type of virus, so when the real thing comes, you body remembers how to be immune to it.
Note: Vaccines do not get you sick. You may feel sick a little bit, but that is your body reacting, as it does not know this dummy virus does no harm.
What else can I help you with?
Can vaccines work on viruses?
Yes, a large percentage of vaccines are for viral infections, there are not many vaccines for bacterial infections but there are a few. The flu is caused by a virus, vaccinations against the flu work very well, for example.
Do vaccines work against viruses and bacteria?
No. Vaccines are not used for treatment. They are used as prevention.
Explain how vaccines work and evaluate their use?
vaccines work by getting injected by the vaccine and then when your body recives it starts protecting itself and makes antibodies

How do you prepare a Work Plan?
Are speeches hard?
Well, if you prepare yourself mentally and recite your speech in front of a mirrior or something, then you can work on the flaws on how well you perform your speech.
What type of scientis studies viruses?
Virologists study viruses. They investigate their structure, life cycle, and interactions with host cells, as well as work on developing treatments and vaccines.
Why dont vaccines work?
They do work for the particular strain of the virus. The reason it doesn't stop everything is because the virus will mutate making a whole new strain and also making it impossible to have vaccines for every kind of flu out there.
What was louis pasteur remembered of?
Louis Pasteur is remembered for his work on the development of vaccines for rabies.
What are the test on animals for?
= "What are the test on animals for?" = = They test mainly new vaccines that they want to make available to humans, so they test on animals to make sure that the vaccines are safe, and actually work. =
Can vaccines be used to change future DNA?
Vaccines do not change future DNA. Traditional vaccines work by introducing an antigen to stimulate the immune system without altering the genetic material of the recipient. Some newer technologies, like mRNA vaccines, provide instructions for cells to produce a harmless piece of a virus, but they do not integrate into or modify the recipient's DNA. Overall, vaccines are designed to enhance immunity rather than to alter genetic information.
Why do you need to prepare the ingredients tools and equipment before starting to work?
So you won't have to stop in the middle of work to get something or prepare something.
What are vacc ines for?
Vaccines are biological preparations designed to provide immunity against specific infectious diseases. They work by stimulating the immune system to recognize and fight pathogens, such as viruses or bacteria, without causing the disease itself. By introducing weakened or inactive components of the pathogen, vaccines prepare the body to respond more effectively if exposed to the actual disease in the future. This helps prevent illness, reduces transmission, and contributes to public health by promoting herd immunity.
