The head of Zagreb's Hospital for Infectious Diseases, Alemka Markotic, told a press conference on Wednesday that Croatia had preordered 1.5 million doses of vaccines, the procurement of which would be organised by the European Union.

She said that according to World Health Organisation’s data, there were currently 28 vaccines in clinical trial, with only six in phase 3. Two are from China, the others are from America and England, while the Russian one is not on that list.

“It will be necessary to obtain additional scientific information on their (Russian) procedure. But there is suspicion at the level of the entire professional community that the procedure was too fast and that phase 3 was not carried out to the extent it should be,” Markotic said.
