Researchers at the University Medical Center Ulm have discovered protein contamination in the vaccine of the manufacturer AstraZeneca. This was reported by the news agency DPA on Thursday (27. 5.) Whether the effectiveness of the vaccine is influenced by this or whether there is a connection to vaccination reactions, but can not be answered, the researchers emphasized in a statement on the study, which has so far only been published as a preprint. This must be clarified in further studies. However, the protein content per vaccine dose was significantly higher than the theoretically expected amount.
The British-Swedish pharmaceutical company, on the other hand, said that clinical experience suggests that the proteins remaining in the vaccine are at a safe level and in some cases lower than in other similarly manufactured vaccines. It said 100 percent purity cannot be achieved. The company is working to the highest possible standards.
