Because vaccines are the disease ,but dead so your white blood cells get ready when the actual disease comes. It is NOT a treatment. It is NOT a prevention.
Vaccination is the most effective tool for prevention of infectious diseases.
active immunization by vaccination
People get booster shots to enhance or restore immunity that may have diminished over time after the initial vaccination series. Boosters help maintain effective protection against infectious diseases, particularly as new variants may emerge or as the immune response wanes. They are crucial for ensuring continued immunity in vulnerable populations and for controlling outbreaks.
Tetanus is non-infectious; it is caused by a toxin produced by the bacterium Clostridium tetani, which is typically found in soil, dust, and animal feces. The bacteria enter the body through wounds or cuts, but they do not spread from person to person. Vaccination is the most effective way to prevent tetanus infection.
Vaccination
Yes, Salmonella typhi is infectious. It is the bacterium that causes typhoid fever, primarily transmitted through contaminated food and water. Infected individuals can shed the bacteria in their feces, posing a risk to others if proper hygiene practices are not followed. Effective sanitation and vaccination are crucial for preventing the spread of this pathogen.
yes
preventing infectious diseases by stimulating the immune system to produce an immune response without causing the disease itself. This helps protect individuals and communities by building immunity and reducing the spread of diseases.
Diatomaceous earth can be effective in controlling hornets by dehydrating and killing them when they come into contact with it.
Penicillin is effective for some infectious diseases, like strep throat and syphilis. It does not cure most infectious diseases.
Gelatin vaccines are effective in preventing the spread of infectious diseases by stimulating the immune system to produce antibodies against specific pathogens.
Generally diseases caused by viruses like nausea, AIDS and other can not be treated by vaccination as we do not have their vaccines or if have then they are not so effective.
