he found out that if you have had cow pox you will never have smallpox so he took some puss out of a cowpox spot and injected a young boy called James Phipps 8 weeks later the young boy was fine and never had smallpox. this was called a vaccination. :P
Viruses
They arent alive
Edward T. Haslam is the author of the book "Dr. Mary's Monkey: How the Unsolved Murder of a Doctor, a Secret Laboratory in New Orleans and Cancer-Causing Monkey Viruses Are Linked to Lee Harvey Oswald, the JFK Assassination, and Emerging Global Epidemics." The book explores a controversial theory connecting the JFK assassination to the development of cancer-causing monkey viruses.
No, viruses do not meet all the criteria of the cell theory because they are acellular entities that cannot carry out cellular functions on their own. Viruses require a host cell to replicate and carry out their life cycle.

This is a very big conspiracy theory, but it is most likely false. Viruses were one of the first types of software ever made. These viruses were harmless and were only created to prove a theory about self-replicating automata.
Vaccinations can in theory be created for any disease which can be cured by the immune system. Typically that means any disease casued by a bacterium or a virus. In practice some diseases are much more worth spending time and money on than others, for example there are many thousands of cold viruses known but it would be impracticle to vaccinate everyone against all of them! Where as some diseases which are known to lead to deaths or disablements are more "worth" the money in designing and testing the vaccine.

Viruses are not considered part of the cell theory because they are acellular entities that require a host cell to replicate.
