The Netherlands will stop using the vaccine until at least March 29, while Ireland has suspended its rollout over concerns about side effects.
Regional authorities in northern Italy have also stopped using a batch of AstraZeneca shots after a teacher died following his vaccination.
They are investigating whether there is a connection between his death and the jab.
Denmark, Norway and Iceland have already halted use of the vaccine while authorities investigate whether it is linked to blood clots.
The pharmaceutical giant said a review of all available safety data of more than 17 million people given the AstraZeneca jab across Europe and the UK showed no evidence of an increased risk of blood clots.
Its chief medical officer Dr Ann Taylor said the number of cases of blood clots reported was lower than the hundreds of cases that would be expected among the general population.
Prime Minister Scott Morrison has previously stated Australian authorities do not hold concerns about the AstraZeneca jab.
But with more European nations turning their backs on the vaccine, there are concerns about Australia's reliance on the drug.
Some Australians are being offered the Pfizer vaccine, but the vast majority will be given AstraZeneca.
The first AstraZeneca batch being produced in Australia is expected to be available later this month.
Department of Health boss Brendan Murphy is hoping CSL can ramp up production so more doses are made available.
"If we get extra AstraZeneca production from CSL, I imagine all Australians will potentially have received it by the end of October," Professor Murphy told reporters on Sunday.
Opposition Leader Anthony Albanese is concerned about Australia's sluggish pace with the vaccine rollout.
The government promised four million people would get their first jab by the end of this month but with just over two weeks to go, only about 150,000 people have been vaccinated.
"We are way, way short," Mr Albanese said.
"We had Scott Morrison in his usual way say that black is white and suggest that he hadn't really meant that everyone would be vaccinated by October when they have said they would on multiple occasions."
The prime minister received his second Pfizer jab on Sunday.
And his government has also launched a campaign against misinformation on vaccines with a new website aimed at "sorting the fact from the fiction".
