Safety and legislation

Vaccine safety is closely assessed in vaccine trials.

  • Healthcare professionals monitor the health and symptoms of the person participating in the trial throughout the trial.

  • Safety may also be assessed more broadly using health registries and databases

  • An experienced physician is always responsible for vaccine trials and the safety of clients. Based on the monitoring, he or she continuously assesses the symptoms reported by the client or adverse events reported in the registries and determines whether they are possibly related to the vaccination

The goal of vaccine research is to make new, as effective and safe as possible vaccines available that protect the population from serious diseases. The development of new vaccines is typically a process that takes years and involves many stages.

  • Only a small proportion of the products progress to clinical trials for humans

  • Before receiving a marketing authorization, the vaccine has been studied in several clinical vaccine trials, in which tens of thousands of volunteers have participated

  • The study of the safety of the vaccine continues even after the marketing authorization has been granted. At this stage, it is also monitored how the disease prevented by the vaccine becomes less common after vaccinations have started

Safety

All drug trials, including vaccine trials, have strict quality and safety requirements. For vaccines, the quality of the research evidence must be particularly strong.

Vaccines may cause mild and transient side effects in some vaccinated individuals, such as redness or itching. These are normal vaccination reactions. FVR staff are available to volunteer subjects throughout the study.

Legislation

All vaccine trials comply with laws, regulations and EU regulations regarding pharmaceutical trials.

Suspected harm

Vaccine safety and vaccine-related adverse events are usually the most important issues to be investigated in a study. Information on adverse events occurring during the study is collected in accordance with legislation and the study-specific research protocol.

  • Participants in vaccine trials are instructed to report all significant health-related events, especially any hospitalizations, according to study-specific guidelines.

  • Often, potential adverse events are reported through regularly completed electronic diaries.

  • Information is also collected through regular study office visits and remote contacts.

You can always contact your research clinic if you have any questions about the study, suspect an adverse reaction caused by the vaccine, or have been hospitalized.

Adverse reactions and sudden illnesses

  • If you suspect an adverse event related to the investigational product, please report it to the study staff according to the instructions you received. If you are unsure about reporting or have any questions regarding adverse events, please contact your own study clinic.

  • If you suddenly become ill, contact the emergency health unit in your area. In urgent emergencies, call the emergency number 112.

  • If you need to be hospitalized while participating in a vaccine study, we ask that you notify the staff of your vaccine study clinic as soon as possible.
