Title: Conceptions about microbes, immunity and vaccines

Pathogenic microbes

Q: Microbes are ...
- nearly always harmful to humans, both bacteria and viruses.
- nearly always harmful to humans if they are viruses, but less often if they are bacteria.
- rarely harmful to humans.
- I don't know.

Microbe size

Q: Which of the following is correct?
- Bacteria and viruses are similar in size.
- Bacteria are larger than viruses.
- Viruses are larger than bacteria.
- I don't know.

Toxin productions

Q: Which of the following microbe kinds might produce toxins when infecting humans?
- Viruses.
- Bacteria.
- Viruses and bacteria.
- I don't know.

Virus structure

Q: Viruses ...
- consist of cells which are similar to human cells.
- consist of cells which are rather different from human cells.
- do not cosist of cells.
- I don't know.

Virus reproduction

Q: Viruses reproduce themselves ...
- only inside the human body.
- both inside and outside from the human body.
- only outside from the human body.
- I don't know.

Pathogen action

Q: When pathogen microbes enter the human body ...
- they will definitely cause a disease, soon or later.
- they will definitely cause a disease, but it migh be very mild.
- they might not cause any disease.
- I don't know.

Incubation period

Q: It is common for a disease to have a few days from the moment that microbes infect humans until illness symptoms appear. Why do you think it happens so?
- Time is necessary for the microbes to spread all over the body.
- Time is necessary for the microbes to reproduce themselves.
- Time is necessary for the microbes to enter the blood circulation.
- I don't know.

Antibodies

Q: What are antibodies?
- Cells that are produced by the human organism that fight pathogen microbes.
- Chemical substances that are produced by the human organism that fight pathogen microbes.
- Medicines that are prescribed by the doctor to confront the disease.
- I don't know.

Re-infection

Q: What happens when someone catches the same disease for a second time?
- The disease is usually milder and shorter than the first time.
- The disease might be more or less severe than the first time, depending on the disease.
- It is impossible for someone to catch the exactly same disease for a second time.
- I don't know.

Vaccine ingredients

Q: What of the following would be common to find inside a vaccine?
- Medicine against microbes.
- Antibodies.
- Microbes.
- I don't know.

Vaccine function

Q: What happens when someones gets a vaccine shot?
- Microbes, which are similar or the same as the ones causing the disease, are introduced into the human body.
- Microbes, which fight against ones causing the disease, are introduced into the human body.
- Special medicines, e.g. antibiotics, are introduced into the human body.
- I don't know.

Vaccine timing

Q: Vaccines are usually efficient against a disease when done ...
- before the disease is catched.
- during the disease.
- after the disease is over.
- I don't know.

Herd immunity

Q: What has do be done to have a country protected against a disease through vaccination?
- The whole population has to be vaccinated.
- The vast majorit of the population has to be vaccinated, but not everyone.
- It is impossible for a whole contry to be protected solely through vaccination.
- I don't know.

Disease eradication

Q: Would it be possible to eradicate diseases globally through vaccination?
- Yes, in the most cases.
- Yes, but only under very special circumstances.
- In no case.
- I don't know.

Vaccination necessity

Q: Supposed that in a country there has been an annual vaccination programme for the last 20 years. Do you think it is still necessary for people do get vaccinated?
- No, the population has gained immunity over the many years of vaccinations.
- Only for people who travel abroad and might catch the disease in another country.
- Yes, if there are not many people vaccinated, the disease might reappear.
- I don't know.
