Yes, antigenic proteins from specific pathogens can be used to develop vaccines. These proteins can stimulate the immune system to produce antibodies and memory cells that can recognize and protect against future encounters with the pathogen, thereby providing immunity.

What is an antigenic variation?
Antigenic variation is a mechanism used by certain pathogens, such as viruses and bacteria, to change their surface antigens, making it difficult for the immune system to recognize and mount an effective response against them. This allows the pathogen to evade immune detection and establish persistent infections in the host.
What is a dead or altered viruses or bacteria that are used to stimulate the body to be on alert are called?
Dead or altered viruses or bacteria that are used to stimulate the body's immune response are called vaccines. Vaccines contain weakened or inactivated forms of the pathogen, or certain proteins or subunits of the pathogen, to trigger an immune response without causing the disease. This allows the body to recognize and fight the pathogen more effectively if encountered in the future.
Many pathogens injure the host by producing what?
Many pathogens injure the host by producing toxins. Toxins are harmful substances produced by certain pathogens that can damage host cells, tissues, and organs, leading to the development of disease symptoms.
What is a pathogen that grows inside a cell called?
An intracellular pathogen is a pathogen that grows inside a host cell. Examples include viruses, some bacteria like Chlamydia, and certain parasites like Plasmodium.
Are viruses pathogen?
Anything that causes disease is considered to be pathogenic. This includes viruses and bacteria. People who come in contact with certain of these organisms may become very ill.

Is it true that antigenic proteins from certain pathogens can be administered as vaccine's instead of using weekend or killed viruses?
True.
What is the difference between antigenic and phase variation?
Antigenic variation involves changes in surface antigens on a microorganism to evade the host immune response, while phase variation involves reversible on/off switching of certain genes to alter the expression of specific surface molecules. Both mechanisms contribute to pathogen adaptation and immune evasion.
Why do vaccines have to be changed every year?
Because certain viruses and bacteria evolve to become resistant to the old vaccines.
A vaccine provides?
Vaccines provides active immunity to certain diseases.

Why do vaccines are giving to people?
in order to immunize them against certain diseases. (2) :)
What is special about vaccines?
Because it helps to prevent certain diseases to immunize our body
Why are people vaccinated?
People are given vaccines so that they are protected from certain illnesses.
