A Ministry of Health, Labor and Welfare official said offering the drugs to other countries was considered but legally difficult. Among the 2 million doses of Pfizer Inc.'s nirmatrelvir and 1.6 million doses of Merck & Co.'s molnupiravir procured by the government, about 1.75 million doses of nirmatrelvir and some 780,000 doses of molnupiravir were disposed of, according to the ministry. The government also secured 2 million doses of Shionogi & Co.'s ensitrelvir but about 1.77 million of them are unused, the ministry said. They are expected to be discarded after they reach their expiration dates starting next fiscal year.
