(ČIA) From January 1, 2022, the validity of vaccination certificates will be reduced to nine months. After vaccination with the third booster dose, the validity of the certificate is not limited at this time. The reduction in validity is based on a recommendation from the European Commission. Registration for the third booster dose of the vaccine was launched this week. The Ministry of Health will also open on December 13 a vaccination centre in the Kotva department store in Prague, set up by the General University Hospital.
