“Kommersant”: it is possible to obtain a certificate for a QR code on the portal of state services and at the MFC 
who received a medical treatment is possible on the portal of public services, in the MFC or in other institutions. According to Kommersant, negotiations are also underway with Russian Post.
As the publication revealed, based on the logic of the bills submitted to the State Duma by the government and explanations given by the authorities, the current QR codes and certificates of Russians who have a regional status will be automatically replaced in information systems with new certificates.
An old paper document will not function, at least as a way to “pass” somewhere. At the same time, paper certificates of the new version can be obtained from the MFC and the structures replacing them.
The Ministry of Health is empowered to determine the validity period of QR codes for different categories of Russians: separately for vaccinated and separately for those who have recovered. Sources of the publication admit that the validity of the certificates can be reduced from a year. The Russian Ministry of Health also recommends to be vaccinated again six months after the initial vaccination or a previous illness.
Earlier, Deputy Prime Minister Tatyana Golikova said that with the introduction of QR codes in transport and public places in Russia, a transition period will be announced. which will last until February 1, 2022. According to her, the Russian government has already submitted to the State Duma draft amendments regarding the use of QR codes. It is assumed that such measures will be in effect in the regions until June 1, 2022.
