Vaccines are used to prevent Infectious Diseases. You use them before you get sick to avoid illness. Some vaccines are for use seasonally (e.g., flu vaccines) and some are used only at certain ages in the normal vaccination schedules. It depends very much on the type of vaccine and the diseases they are intended to prevent, the age of the patient, and the location where the patient lives and/or travels. Your health care professional can provide you a listing of the recommended types of and times for the vaccinations recommended for you.
No vaccines are made this way. None.
The use of vaccines is classified primarily into two categories: preventive and therapeutic vaccines. Preventive vaccines aim to protect against diseases by stimulating the immune system to recognize and fight specific pathogens before infection occurs. Therapeutic vaccines, on the other hand, are designed to treat existing diseases, particularly cancers, by enhancing the immune response against the disease cells. Additionally, vaccines can be categorized based on their composition, such as live-attenuated, inactivated, subunit, or mRNA vaccines.
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 work by getting injected by the vaccine and then when your body recives it starts protecting itself and makes antibodies
Many vaccines are still in use today.
A vaccines helps because they put some of the disease in your body then your body can get use to it so if you get that disease your body can easily fight it out of you!
If the vaccines are supposed to be kept refrigerated until use, they are worthless if they are no longer cold.
Cholera Vaccine. Flu vaccines formulated for injection use inert/inactive virus particles ("dead"), while flu vaccines for nasal mist are made as a LAIV (live attenuated influenza vaccine), which means they are "alive" but weakened chemically to prevent them from being able to cause illness.
Vaccines use a weakened or inert version of the disease, in order to stimulate the body's natural defenses should it come into contact with a more potent form.

Both, because its for Vaccines and regular medicine.
In the US it was the Food and Drug Administration (FDA) and in Europe it was the European Medicines Agency (EMEA) who approved the H1N1/09 vaccines for use.
