Some Russians took to social media on Friday to voice frustration after 300,000 doses of the country’s Sputnik V Covid-19 vaccine were supplied to Argentina, arguing that more shots should be made available at home, Reuters reports.

Though the vaccine is readily available in Moscow, relatively small batches have so far been delivered to many Russian regions as part of a mass inoculation programme, with several reporting receiving 2,000 doses or less so far.

Novgorod has received 600 doses for civilian use thus far, according to an official in the local government. Kaliningrad has received 400, according to the Interfax news agency.

“Better hurry to Argentina to get vaccinated then,” Alexander, a resident of Kaliningrad, said on Twitter.

The Samara region has received 2,751 doses of Sputnik V for civilian use, according to local officials, and a further 1,000 for members of the military based there.
