Pharmaceutical company Pfizer is seeking €650 million (3.4 billion Romanian leu) in compensation from Romania for COVID-19 vaccine doses the country did not accept. The Romanian Ministry of Health confirmed receipt of a notice from Pfizer requesting payment within two months. The demand stems from vaccines ordered during the pandemic that Romania ultimately did not utilize. Details regarding the original contract terms and reasons for non-acceptance have not been fully disclosed. This situation raises questions about vaccine procurement agreements made during the height of the COVID-19 crisis across Europe. The Romanian government is currently reviewing the claim and its legal options. This is not the first instance of disputes arising from COVID-19 vaccine contracts between pharmaceutical companies and European nations.
