The European Union has agreed to pay a premium on new orders of COVID-19 vaccines because it is requiring tougher terms to be met, European officials said, as the bloc tries to protect supplies after a rocky start to its vaccination campaign.
The higher price is less than the United States has agreed to pay in its latest order in July.
On Sunday, the Financial Times reported the EU has agreed to pay Pfizer and BioNTech 19.5 euros ($23.1) for each of their COVID-19 shots under a contract signed in May for up to 1.8 billion doses, up from the 15.5 euros per dose under two initial supply contracts for a total of 600 million vaccines.
The price for Moderna shots went up to $25.5 a dose, the newspaper said, referring to a 300 million vaccine deal, up from $22.6 in its initial deal for 160 million jabs.
EU lawmaker Tiziana Beghin, a member of Italy's 5-star ruling party, said the EU was being been ripped off.
"It's inexplicable," she said.
Moderna's price is still at the lowest end of the $25-$37 range indicated by the company last year, but Pfizer and BioNTech had previously said prices would be lower for bigger volume deals.
Others said there were good reasons to pay more and that circumstances had changed greatly from when initial deals were struck with drugmakers last year.
France's European affairs minister Clement Beaune told French radio RFI on Monday the likely higher prices were still under negotiation and were the result of stricter clauses on variants, production and deliveries.
One European official familiar with negotiations with vaccine makers said the value of the drugmakers' shots had risen since evidence had emerged of their efficacy and of the positive impact they had on helping the economy to recover from a pandemic-induced recession.
"Several factors played a role," the official said, speaking on condition of anonymity.
All the vaccines used in Europe have been shown to have a beneficial impact, but those made by AstraZeneca and Johnson & Johnson, have faced restrictions on their use in the EU because of concerns they can in rare instances lead to blood clots.
Those two vaccine makers have also suffered supply problems, which in the case of AstraZeneca have led to legal challenges by the EU.
While the bargaining power of Pfizer/BioNTech and Moderna has increased, additional EU demands are likely to raise the costs of making and delivering vaccines.
A spokesperson for Pfizer declined to comment on the European prices, but said the latest contract with the EU was different from the initial ones, including on matters concerning production and delivery.
The European Commission, which coordinates negotiations with vaccine makers together with EU governments' representatives, declined to comment for this story, citing confidentiality clauses.
Earlier this year, lawmakers, media and some analysts criticised the bloc for paying too little for the early supplies of COVID-19 vaccines, saying that had contributed to initial delays in the vaccination drive.
"It's easy to criticize the EU because it spends little and late or because it spends too much," said Giovanna De Maio, non-resident fellow at the Brookings Institution, a U.S. research group.
"Reality is much more complicated, and perhaps it is correct to give priority to access to vaccines rather than costs given the pace at which the delta variant is spreading," she added, referring to the more transmissible variant that was first detected in India.
On July 23, Washington bought an additional 200 million vaccines from Pfizer at a price of $24 a dose, the company said, up from $19.5 the United States paid for its first 300 million shots.
Pfizer said the higher U.S. prices reflected investment needed to produce, package and deliver new formulations of the vaccine, as well as extra costs in producing smaller pack sizes suited to "individual provider offices, including pediatricians."
When the EU agreed in May its third supply deal with Pfizer for up to 1.8 billion doses, the Commission said the new contract required the vaccines to be made in the EU and the essential components to be sourced from the region.
In its first supply deals, the EU had required that only vaccines were made in the EU, not their components.
Concentrating production in Europe can help guarantee supply now that production lines are well established and there is less need for leeway, but it is also likely to increase costs.
The European Commission also said in its statement that under the new contract "from the start of the supply in 2022, the delivery to the EU is guaranteed," whereas under the first contract Pfizer was only required to make its "best reasonable efforts" to ship pre-agreed volumes by set deadlines.
Pfizer has so far respected its commitments to the EU, and has delivered slightly more than initially planned in the first quarter of the year.
Another big change since the early contracts is the emergence of variants and concerns vaccines may not be effective against them.
EU officials said governments could refuse to buy shots that did not protect against variants, while companies will be expected to quickly adapt their vaccines, potentially at significant cost.
