The Ministry of Transport released a list of logistics companies as the main carriers to transport the doses of the COVID-19 vaccines to meet the transportation needs for vaccination.

Sun Wenjian, spokesman for the ministry, said the ministry investigated the transport capacity and has promoted cooperation between the enterprises for vaccine production and transportation, at a news conference on Thursday.

Some 56 logistics companies are on the list. Sun added that the top 30 logistics companies to transport medicines have nearly 8,000 vehicles with frozen storage, and about 300,000 frozen boxes, which meet the country’s need for transporting vaccine doses.

The ministry has created free shipping accounts for vaccine production companies and 32 provincial-level centers for disease control, transporting over 1.6 million doses of vaccine for free.

According to the National Health Commission, as of Tuesday, more than 546.71 million doses of COVID-19 vaccines had been administered across China.
