He added: "Let's celebrate what AstraZeneca have done and it only underlines how important it is for everybody to work together in order to keep their populations safe."
His lavishing of praise comes after a multitude of attacks on the jab from the EU.
At the start of February, French President Emmanuel Macron described the vaccine as "quasi-ineffective" while multiple countries banned its use in older people saying there was no evidence to support its use.
Over the past week, over a dozen countries have also suspended the use of the jab completely due to concerns over blood clots.
The European Medicines Agency and the World Health Organisation have both dismissed suggestions the blood clots are linked to the jab and have recommended its continued rollout.
At the same time, AstraZeneca has found itself at the heart of a series of attacks from the European Commission after the manufacturer admitted production issues meant it would be unable to supply as many doses to the EU in the months ahead as it had originally promised.
Yesterday, Commission President Ursula von der Leyn threatened to seize control of AstraZeneca's European factories and block exports of its jabs from the continent unless more doses were delivered to the EU.
Speaking in the Commons today, Mr Hancock warned the EU not to break contractual law.
He said: "I think that it is vital that we all work together.
"These supply chains for the manufacture of these vaccines cross borders.
"They are often global supply chains and it is vital that we work together to deliver them and there is a need for that co-operation and there is of course a need for all countries to respect contract law.
"That is the basis of international trade and I'm sure that the European Union will live up to the commitments and statements that it has made, including President von der Leyen herself who has said that there should not be restrictions on companies when they are fulfilling contractual responsibilities.
"Of course there should not and we fully expect those contracts to be delivered on because there are very significant consequences to breaking contract law."
While Ms von der Leyen has previously given reassurances to Prime Minister Boris Johnson about the continued supply of vaccines from the continent, yesterday she warned exports from the EU could be banned due to the UK rolling out jabs quicker than the bloc.

"We want reliable deliveries of vaccines, we want increase in the contracts, we want to see reciprocity and proportionality in exports and we are ready to use whatever tool we need to deliver on that.
"This is about making sure that Europe gets its fair share."
Mr Hancock's praise for AstraZeneca came after the health select committee chair, Jeremy Hunt, said it was "incredibly dangerous" of the EU to "make threats to the supplies of vaccines and components, alongside casting aspersions over their safety."
