Yes, you can get another booster vaccination if you want it for travel purposes. In this case, you will have to pay for the vaccination yourself. The price is determined by the cantons and vaccination centres. Contact your cantonal authority to find out where you can get a booster (known as a travel vaccination).
You need to wait at least 4 months after your last COVID-19 vaccination.
The travel-related additional booster is off-label use (i.e. it is used in a different way than it was authorised for by Swissmedic) and is not recommended by the FOPH or the FCV. It can be administered by the attending doctor provided they comply with the duty of care and the duty to inform patients. Please note: in the case of a vaccination that is not authorised and not recommended, certain costs for any damage may not be covered and you as the person being vaccinated will have to cover them yourself. If you are unsure, please ask.
You will find more information in the FAQs Who is liable for any vaccination damage?.
Important to remember:
According to the current science (unless you are at especially high risk), if you are fully vaccinated (i.e. initial immunisation and booster, generally three doses).), then you are still effectively protected against severe disease requiring hospitalisation. The epidemiological situation is being closely monitored so that the recommendations can be adapted if necessary.
