Mexico reported a near-record 1,707 confirmed coronavirus deaths Wednesday, as the country runs out of vaccines.

The Health Department reported Mexico’s COVID-19 deaths now total 161,240, and confirmed infections rose by 12,153 to nearly 1.89 million. Estimates based on excess-death statistics suggest the real death toll is over 195,000.

Mexico approved Russia’s Sputnik V vaccine Tuesday, but has not yet signed a purchase contract and does not have a firm date for its first delivery. The government had hoped to get 400,000 doses by the end of February.

Mexico has received about 766,000 doses of the Pfizer vaccine and has administered about 686,000 shots, with much of the remainder set aside for second doses. The next Pfizer shipment is not expected until mid-February.

Meanwhile, the government website set up to register people for vaccines when they do arrive was overwhelmed and inoperable for a second straight day.

Authorities have said they are still working on getting enough server capacity to handle the number of people attempting to register.
