Ethical Issues of Vaccines

There are always ethical issues surrounding medical interventions. Asking questions about the situation will help to identify and consider the ethical issues:

Researching vaccinations

Researching vaccinations

  • Who should be responsible for researching and producing vaccines?
  • When testing the effectiveness of vaccines, is it ethically acceptable to have a control group who will not be vaccinated?
Who should receive vaccinations?

Who should receive vaccinations?

  • When stocks of vaccines are low, which groups should be prioritised?
  • If a vaccine is available but expensive, should the NHS be forced to provide it?
  • Should vaccinations be compulsory for children in schools?

Ethical Issues of Antibodies

There are always ethical issues surrounding medical interventions. Asking questions about the situation will help to identify and consider the ethical issues:

Information

Information

  • Should patients be told if the monoclonal antibodies used for treatment or testing have been produced using transgenic animals?
  • If B cells have been obtained from another person, should they be anonymous donors?
Side effects

Side effects

  • Should people with multiple sclerosis be denied treatments involving monoclonal antibodies because of the potentially increased side effects?
