These substances are called "vaccines".
Pneumococcal polysaccharide disease is caused by a bacteria. It can be deadly but a vaccine was developed to head off the disease before it starts. The vaccine works when a small amount of the bacteria is injected into the patient and his or her immunity works against the disease, causing immunity.
it prompts the body to produce immunity to a disease:)
If a person's immune system is producing antibodies against a specific antigen, then that person has a positive or active immunity toward that antigen. If a person has merely been injected with antibodies but does not produce them, that is a passive immunity.
Acquired immunity is a form of immunity gained from bacteria or viruses by the body ITSLEF. Essentially the body has encountered the pathogen (bacteria/virus) and learnt by itself which anti-bodies to produce to fight it. Once the body has found which antibodies are the most effective this information is stored in "memory cells" which, if encounter the same pathogen can quickly make the correct type antibodies to fight the invading pathogen and defeat it quickly. (antibodies are produced by lymphocytes which neutralize toxins and clump bacterium together meaning the phagocytes can engulf them quicker and digest via enzymes) acquired immunity is "natural" including Innate immunity (antibodies passed through placenta/breast milk. artificial immunity includes Active (given modified bacteria which does no harm but body learns how to produce antibodies) and Passive (injected with Antibodies - requires "top-up")
They took dead cow pox virus and injected it into humans . This developed an immunity in the host.
smoking
It does the same as when you take it by mouth. It kills bacteria in the body.
There is always a chance of death when substances are injected regardless of what they are.
Botullosis is used in Botox. It is a deadly bacteria that can paralyze you. But when used in botox. It is injected into wrinkles. It paralyzes that muscle
that it was very gay
To find out, he took a culture of these cells, heated the bacteria to kill them, and injected the heat-killed bacteria into the mice. The Mice survived, suggesting that the cause of pneumonia was not a chemical poison released by the disease-causing bacteria.
Some examples of poisonous substances produced by living organisms include botulinum toxin from bacteria, ricin from plants, venom from snakes, and formic acid from insects. These substances can be harmful or deadly when ingested or injected into other organisms.
