nope it depends when its vaccine for viruses the price is so high when its for vitamins the price is normal you can be healthy without vaccine just eat nutritious foods
Because certain viruses and bacteria evolve to become resistant to the old vaccines.
Vaccines are used to make your body produce antibodiesand T-cells against viruses or bacteria! The Measles and Flu vaccines are viral. The Whooping Cough (Pertussis) and Tuberculosis vaccines are bacterial.
No. Vaccines are not used for treatment. They are used as prevention.
These substances are called "vaccines".
Vaccines against parasites are limited compared to vaccines against viruses and bacteria. Some examples include vaccines against malaria, such as Mosquirix. Research is ongoing to develop more vaccines against parasitic infections like hookworms and schistosomiasis.
Vaccines are for preventing infections. Infections are pathogenic (caused by germs). Vaccines help your body prepare to fight specific pathogens, e.g., bacteria and viruses.
DNA of harmless bacteria or viruses.
Protists are not commonly used in the development of vaccines. Vaccines are typically made using viruses, bacteria, or parts of these organisms to stimulate the immune system to produce an immune response. Protists are a diverse group of eukaryotic microorganisms, but their use in vaccines is limited.
Vaccines don't kill viruses or diseases; they prevent disease before you are infected.

Antibiotics only works against bacteria! Since Viruses are not living things, ( because they are single celled organisms) they can only be prevented and can never be "cured". To prevent from obtaining viruses, you get Vaccines (shots). Vaccines are weak or dead viruses injected into your body to release mass amounts of B cells that will help fight against the disease.
A fluid containing weakened disease-causing viruses or bacteria is known as a vaccine. Vaccines stimulate the body's immune system to produce antibodies to protect against future infections by the same pathogen.
