What do vaccines contain?

Answers

Answer 1

Answer: Vaccines contain dead bacteria to get ready to fight the real bacteria/virus. Imagine like that every time you take a vaccine the body makes a blueprint of it. Then, when the virus/bacteria comes, the body knows the bacteria/virus because they made a blueprint. Now, the flu vaccine is different because they change very much. They change every year, so that is why you take flu vaccines yearly.

Answer 2

Answer:

Vaccines contain several key components, these components include antigens, adjuvants, stabilizers, and preservatives.

Antigens are substances in vaccines that resemble parts of disease-causing pathogens, such as viruses or bacteria.

They stimulate the immune system to recognize and respond to these specific pathogens.
Antigens in vaccines can be weakened or inactivated forms of the pathogen, proteins, polysaccharides, or genetically engineered components.

Adjuvants are added to some vaccines to enhance the immune response.

They help to improve the recognition of the antigen by the immune system, leading to a stronger and longer-lasting immune response.
Common adjuvants include aluminum salts, oil-in-water emulsions, or other compounds.

Stabilizers are included in vaccines to maintain their effectiveness during storage and transportation.

They help preserve the integrity and potency of the vaccine over time.
Stabilizers can include sugars, proteins, or gelatin, which help protect the vaccine from damage or degradation.

Preservatives are used in some vaccines to prevent bacterial or fungal contamination.

They help maintain the sterility of the vaccine and ensure its safety.
Thimerosal, a compound containing mercury, has been used as a preservative in some vaccines.

Thus, antigens, adjuvants, stabilizers, and preservatives are a few of the essential components found in vaccines.
