If you have a history of anaphylactic reactions, vaccination with the "BNT162b2" vaccine from BioNTech / Pfizer is not recommended. This is emphasized by the MHRA in the UK after two cases in vaccinated people.
The Corona mass vaccination program for the elderly and at-risk healthcare workers with the vaccine "BNT162b2" from Pfizer and BioNTech began on Tuesday in the United Kingdom (UK). In the meantime, two cases of anaphylaxis and one possible case of another allergic reaction have occurred, reports the new UK drug authority "Medicines and Healthcare Products Regulatory Agency" (MHRA).
"People with anaphylactic reactions to vaccines, drugs, or food should not be vaccinated with the Pfizer / BioNTech vaccine," said the CEO of the MHRA, Dr. June Raine, quoted in UK media.
The expert emphasizes: "Most people will not get anaphylaxis and the benefits of the protection outweigh the risks." And: You can have complete confidence that the vaccine meets the robust MHRA standards for safety, quality, and effectiveness, assures Raine.
No vaccination if you have a history of anaphylaxis!
Anaphylactic shock is a serious to life-threatening event. Even before the start of the vaccination program, the MHRA had advised against vaccination with "BNT162b2" for people with a history of such a complication. The authority has now announced an investigation that the manufacturers want to support.
According to Pfizer, people with severe reactions to vaccines or the excipients in "BNT162b2" were generally excluded from studies on the vaccine. The allergic reactions could possibly have been triggered by polyethylene glycol (PEG), a stabilizer in the new vaccine that is not found in other vaccine types.
Allergic reactions in every thousandth vaccinated person?
The vaccination program documents show that in the "BNT162b2" studies, 0.63 percent of the participants in the vaccination group and 0.51 percent in the placebo group reported possible allergic reactions.
Chronicle of development and events
In the British media, the vaccination expert Professor Peter Openshaw from Imperial College in London is quoted that he considers the proportion to be very low. "The fact that we were informed about the allergic reactions so quickly and that the authorities reacted so quickly with precautionary measures shows that the monitoring is working," he emphasized in the media.
Allergies to vaccines are obstacles to vaccination
In Germany, it is well known that prior to vaccination, possible vaccination reactions and contraindications must be clarified and this must be documented. According to the "Recommendations of the Standing Vaccination Commission", vaccination obstacles are also allergies to vaccine components such as neomycin and streptomycin and, in rare cases, chicken protein (Epi Bull 2020: 34, page 32).
"People who react with anaphylactic symptoms after ingesting chicken protein should not be vaccinated with vaccines that contain chicken protein (yellow fever, influenza vaccine)," emphasizes the organization.
