Storyboard Text

  • What Do Vaccinations Contain?
  • How Are Vaccines Are Put Into Patients?
  • How Do The White Blood Cells Respond To Vaccines?
  • Vaccines contain some of the virus that it is treating against, which are usually dead or weakened viruses, this tricks the body into thinking a live virus has entered the body and creates antibodies, so if the real virus does ever enter the body, the body recognizes the virus and removes it.
  • How Long Are Vaccines Effective For?
  • Vaccines are usually injected into the upper arm or thigh, with a jab. A sugar lump is used with a drop of the vaccine on it as an alternative.
  • What Happens In The Case Of A Real Infection After A Vaccination?
  • Firstly, the injection inject a form of pathogen into your body. Secondly, the white blood cells release antibodies. Thirdly, the antibodies attach and clump themselves to the pathogens. Fourthly, the white blood cells engulf and digesting the pathogens, completing the Phagocytosis cycle.
  • Why Do Some Parents Disagree With Vaccinating Their Children?
  • Depending on what type of vaccine it is vaccines can last a life time, others can last only a few months. Vaccines for influenza last about one flu season (about 6 months), whereas a measles vaccine is supposed to last a life time; there are many vaccines that you receive as a child, and over time it weakens and you need a booster when you are older.
  • Getting infected with the disease after you have had a vaccination for it is not very likely, but it can happen and between 1-5% of people vaccinated fail to become immune to the disease. If this happens then they could get ill just like anyone else would, if they didn't have the vaccine.
  • Some parents are refusing to let their children be given vaccines, as they believe that natural immunity is best for them. Others think that it is dangerous to inject the virus into the children, even though they are weakened or dead viruses.
