The government has announced plans to start vaccinating people under 55, who have already received a first dose of AstraZeneca, with a second dose of either BioNTech/Pfizer or Moderna.

This approach will take effect as of Friday, 9 July. It still remains possible to receive AstraZeneca as a second dose.

Only recently, the government had ruled out vaccine mixing pending the European Medicine Agency's approval. But the results of several studies are encouraging, says Luxembourg's Superior Council of Infectious Diseases, which two weeks ago published a statement on the matter.

The Council does recommend, however, that people aged 55 and over, as well as people aged 30 or over and belonging to categories 2b, 3b, 4b or 5b, continue with the same vaccine at an interval of 12 weeks. People that have suffered from thromboembolism after the first dose may still switch to an mRNA vaccine.

Third dose for immunosuppressed patients


A third dose is being recommended by the Council for immunosuppressed patients. The Council states that two doses may not provide sufficient protection for these individuals. A third dose of a mRNA vaccine can be administered.

This applies to patients who have received an organ donation, as well as patients suffering from chronic autoimmune diseases.
