Some countries are restricting the use of the AstraZeneca vaccine against COVID-19 while others have pressed ahead with inoculations as investigations into reports of rare, and sometimes severe, blood clots continue.
The European Union’s medicines regulator – the European Medicines Agency (EMA) – and the World Health Organization (WHO) have said the benefits of the shot outweigh its potential risks, but they are monitoring the situation as more cases are reported.
On March 31, EMA chief Emer Cooke said there was “no evidence” yet that would support restricting the use of AstraZeneca’s vaccine in any population despite the reports of rare blood clots.
Her comments came after an independent vaccine expert panel in Germany said a day earlier that the AstraZeneca shot should not routinely be given to people under the age of 60 because of a rise in reported cases of unusual blood clots in the days after vaccination.
The German government followed the recommendation and said the shot would be limited for use in people aged 60 and above.
AstraZeneca, a British-Swedish company, said earlier in March that its vaccine was 76 percent effective in preventing symptomatic coronavirus infections in a trial held in the United States, and that studies did not indicate higher risks of clotting.
Below are two lists in alphabetical order, the first showing countries that are using the vaccine, albeit some with restrictions by age, and the second showing those that had halted the roll-out of the shot as of March 31.
Several of the countries where the vaccine was being distributed had in the past temporarily barred its use, including EU member states France, Germany and Italy, pending the outcome of an earlier EMA probe that concluded the shot was “safe and effective“.
