Vaccination is the best protection against yellow fever and its complications.

Women receiving the vaccine should avoid becoming pregnant 1 month after the vaccination.

Symptoms after vaccination

Some symptoms may be caused by the vaccine (e.g. redness at the injection site). Other problems may occur by chance and are not related to the vaccine (e.g. cold, gastro, headache).

Yellow fever vaccine is safe. In most cases, it does not cause any reaction.

Frequency Possible reactions to the vaccine What to do

  • Pain and redness at the infection site
  • Apply a cold, damp compress at the injection site.

We recommend that you stay at the clinic for at least 15 minutes after vaccination because allergic reactions may occur. If an allergic reaction occurs, the symptoms will appear a few minutes after the vaccination. The person giving the vaccine will be able to treat this reaction immediately.
