Moscow police said they have launched dozens of criminal probes to crack down on fake inoculation certificates, as vaccine scepticism remains stubbornly high in Russia despite soaring infection rates.
Russia's black market for falsified vaccine certificates is flourishing, largely fuelled by a mistrust of the homegrown Sputnik vaccine.
The underground trade has taken hold even as a third wave of the virus sweeps across the country, breaking national records for virus-related deaths in recent weeks.
A senior Moscow police official said 32 cases had been opened into the falsification of vaccine certificates, according to Russian news agencies.
