Russia reported a record 737 deaths from coronavirus-linked causes in the past 24 hours on Tuesday, pushing the national death toll to 139,316.
The country confirmed 23,378 new COVID-19 cases, including 5,498 in Moscow, taking the official national tally since the pandemic began to 5,658,672.
The federal statistics agency has kept a separate count and has said Russia recorded around 270,000 deaths related to COVID-19 from April 2020 to April 2021.
Health Minister Mikhail Murashko was quoted by TASS on Tuesday as saying that up to 850,000 people were being vaccinated against COVID-19 in Russia every day and building up immunity was key.
The Kremlin would not support the idea of closing borders between Russia's regions to stop the virus from spreading, although some regions may take swift and harsh measures to withstand the pandemic, Kremlin spokesman Dmitry Peskov said on Tuesday.
The recent surge in COVID-19 cases, along with the need to raise interest rates to combat inflation, are seen challenging economic growth in Russia this year.
