Initial immunisation with vaccines authorised in Switzerland
Basically, both injections must be administered with the same vaccine if possible.
- If vaccination was completed either accidentally or e.g. abroad with a different mRNA vaccine that is authorised in Switzerland than the first dose, then you have also received a complete initial immunisation.
- The Pfizer/BioNTech vaccine is recommended in preference for vaccinating people under 30. For those under 30 who have received a single dose of the Moderna vaccine so far, completion of the vaccination series with the Pfizer/BioNTech vaccine is recommended in preference.
- Individuals who have received one dose of AstraZeneca abroad are recommended to complete the series of vaccinations with a second dose of an mRNA vaccine from Pfizer/BioNTech or Moderna.
- People who have been vaccinated with the Janssen viral vector vaccine are advised to supplement their initial immunisation with a dose of an mRNA vaccine from Moderna or Pfizer/BioNTech between 28 days and 4 months after the vaccination with the vector vaccine..
Initial immunisation with vaccines not authorised in Switzerland
People who have been vaccinated with a COVID-19 vaccine not authorised in Switzerland are recommended to supplement their initial immunisation with an mRNA vaccine. The procedure depends on the number of vaccine doses they have received and the vaccine used. You can seek advice on this from your doctor or pharmacist.
