In Stralsund, nursing home employees were injected five times the dose of corona vaccine due to individual error. The process appears to be due to improper processing when preparing the syringes.
After Sunday’s incident, the seven women and one man were sent home. As Vorpommern-Rügen district administrator Stefan Kerth (SPD) said on Monday, four of the eight affected people have been admitted to a hospital for observation as a precaution. They showed flu-like symptoms.
“I am deeply sorry for the incident,” Kerth said. It’s an isolated case dating back to individual mistakes. “I wish everyone affected that they do not experience serious side effects.”
The district reported in its announcement that, according to information from manufacturer Biontech, larger doses of the vaccine had already been tested in test subjects in the phase I study without serious consequences. No permanent adverse events have been reported.
A Biontech spokeswoman confirmed the statement. In tests, amounts up to 100 micrograms were administered without serious consequences. The usual vaccine dose is 30 micrograms.
He referred to your company’s detailed product information. The first sentence reads: “This is a multi-dose vial, the contents of which must be diluted before use.” That was apparently not the case with vaccines in Stralsund.
Typical vaccination reactions
Since the weekend, the BNT162b2 vaccine developed by the German pharmaceutical company Biontech together with the US group Pfizer has been used. Nursing home residents and staff, as well as people over the age of 80, get it first (read more here).
In the phase III study required for approval, the vaccine was administered to more than 20,000 test subjects. Another group received a placebo.
The most common side effects included local reactions at the injection site and flu-like symptoms such as tiredness, headache, or fever.
Serious side effects were extremely rare at around 0.5 percent. Both subjects in the active ingredient group and the placebo group were affected. These included sensory disturbances in the legs or cardiac arrhythmias.
