Yes, you will receive an extra certificate after your booster jab, because in some countries people are already being requested to show this. Your booster certificate will not automatically appear together with your other vaccination certificates. You have to retrieve it digitally or request it by phone yourself.
Your new certificate will be available 2 to 7 days after your third jab.
You can obtain your booster certificate in 3 ways.
In the CovidSafe app
Tap 'Check for new certificates', then sign in with Itsme or eHealth. After a while, your booster certificate will appear above your other certificate(s). The title will be ‘Vaccination 3/3’ or ‘Vaccination 2/1’ (if your first vaccine was by Johnson & Johnson).
On the portals
Go to MyHealth.be, MijnBurgerprofiel, MyHealthviewer or Helena. Log on with one of the digital keys. Itsme is the easiest option. The website will show your certificates. You can download and print them. Be sure to print the certificate of full vaccination (dose 2/2)
You can also call the help desk 24/24 on 078 78 78 50 (in Flanders) or 02 214 19 19 (in Brussels) to have your vaccination certificate sent to you by post.
