To put it simple, your body is injected with either the weak or already dead virus that you want to be immune to. Because the virus is not strong, your immune system can fight it easier but still gain the immunity during the process to avoid being sick, or at least not as bad as you normally would, if you ever catch the real virus in the future.
Yes, a large percentage of vaccines are for viral infections, there are not many vaccines for bacterial infections but there are a few. The flu is caused by a virus, vaccinations against the flu work very well, for example.
vaccines work by getting injected by the vaccine and then when your body recives it starts protecting itself and makes antibodies
No. Vaccines are not used for treatment. They are used as prevention.
They do work for the particular strain of the virus. The reason it doesn't stop everything is because the virus will mutate making a whole new strain and also making it impossible to have vaccines for every kind of flu out there.
Louis Pasteur is remembered for his work on the development of vaccines for rabies.
= "What are the test on animals for?" = = They test mainly new vaccines that they want to make available to humans, so they test on animals to make sure that the vaccines are safe, and actually work. =
Vaccines do not change future DNA. Traditional vaccines work by introducing an antigen to stimulate the immune system without altering the genetic material of the recipient. Some newer technologies, like mRNA vaccines, provide instructions for cells to produce a harmless piece of a virus, but they do not integrate into or modify the recipient's DNA. Overall, vaccines are designed to enhance immunity rather than to alter genetic information.
Edible vaccines are vaccines produced in plants genetically modified through bioengineering.
Yes. I recommend not taking any vaccines, because all of them have horrible side effects. PS. I used to work for the government and they don't really care about how the side effects of these vaccines effect you.
Pfizer is a pharmaceutical company that researches, develops, and manufactures prescription medicines and vaccines to improve health. They focus on areas such as immunology, oncology, cardiology, and vaccines to address a range of medical needs globally.
Vaccines do not cause AIDS.
The invention of vaccines is primarily attributed to Louis Pasteur, who developed the first vaccines for diseases such as rabies and anthrax in the late 19th century. John Dalton is known for his work in atomic theory, while Isaac Newton is renowned for his contributions to physics and mathematics. Therefore, among the three, it was Louis Pasteur who was instrumental in the development of vaccines.
