Across
  1. 3. non-living microorganism that needs a host in order to reproduce
  2. 7. a type of vaccine that uses a weakened live virus in order to induce an immune response in the body
  3. 8. part of a virus that can attach, penetrate and inject the viral genome in a host cell
  4. 9. type of vaccine in which the viral DNA is destroyed but antigens are still present
  5. 11. virus surrounded by a capsid in the shape of an icosahedron
  6. 15. doses of vaccines given periodically in order to "boost" the immune system
  7. 16. replication cycle where viruses are rapidly reproduced and the host cell "bursts" releasing more viral bodies to infect other healthy cells
  8. 17. the process of being resistant to a infectious disease mainly by vaccinations
Down
  1. 1. part of virus made of proteins that can come in varying shapes depending on the type of virus. It helps protect the viral nucleic acids.
  2. 2. when a disease no longer poses a threat to humans because of a worldwide reduction to 0 cases through vaccination
  3. 4. envelope on some viruses that wrap the tail tube
  4. 5. type of virus that has a hollow tube shaped capsid
  5. 6. consists of the dead or weakened version of a microbe and is used to help your immune system recognize the live bacteria in a case of future infection
  6. 7. a substance that can induce an immune response in the human body. Can be a virus, bacteria, pollen, etc.
  7. 10. the reduction of new disease cases in a specified geographical location. Further measures may be needed to prevent new cases
  8. 12. viral replication cycle where viral DNA in integrated into the host cell's genome
  9. 13. process in which live smallpox virus is used to infect healthy individuals in order to immunize them
  10. 14. drugs that can stop virus development at any step in the viral replication process
