London (CNN Business) The European Union is calling out vaccine makers AstraZeneca ( AZN ) and Pfizer ( PFE ) over delivery delays that could slow its recovery from the pandemic . The European Union has devoted part of a €2.7 billion ($3.3 billion) emergency fund to assist with vaccine development. Pfizer said Monday it would return to its original schedule of deliveries for the European Union this week. Supply chain experts are much more concerned by the news from AstraZeneca than Pfizer, given the latter company's commitment to increase output soon. A delay for a week or two "is not a big problem," said Burak Kazaz, a professor of supply chain management at Syracuse University.
