Norwegian health authorities have said the country has a surplus of Covid-19 vaccines and has already discarded more than 137,000 doses because there is declining demand in low-income countries.
The Norwegian Institute of Public Health said it plans a further disposal of doses if global demand does not change.
In Norway there is high vaccine coverage while globally a demand for donations has fallen.
"For the first time during the pandemic, the supply now exceeds the demand for Covid-19 vaccine doses," the agency said, adding that situation applies to most European Union countries.
Norway is not a member of the EU.
Norway has donated 7.4 million doses to more than 25 countries, chiefly through the UN-backed programme known as Covax but also through bilateral donations.
Earlier this month, health officials in neighbouring Denmark said 1.1 million excess Covid-19 vaccines would be discarded because their expiry date was near, and efforts to donate them to developing countries had failed.
According to the Norwegian agency, 93.1% of people older than 18 have received a first dose of a vaccine while 90.7% have had a second shot.
