![]() 6 During the COVID‐19 epidemic focus has been on these two excipients as they are excipients in the first vaccines on the market in Europe and possible culprits for allergic reactions to the COVID‐19 vaccines. Immediate‐type hypersensitivity has been described to several excipients with most reports on polyethylene glycols (PEGs) also called macrogols (E1521) 5 and the structurally related polysorbates. 2, 3, 4Įxcipients are necessary to support and optimize the properties of the active ingredients in vaccines, drugs, and other products. In general, severe allergic reactions to vaccines are rare and caused by either the vaccine itself or by excipients contained in the vaccine. 1 Vaccines were developed with unprecedented speed as a major global preventive measure against COVID‐19, and since December 2020 many million doses of various vaccines have been administered globally. In clinical trials, J&J acknowledged last week that there were two cases of anaphylaxis among participants in the trial.In March 2020 the World Health Organization (WHO) declared a pandemic for severe acute respiratory syndrome coronavirus type 2 (SARS‐CoV‐2)-also called COVID‐19. There have been fewer reported cases of allergic reactions to the J&J vaccine compared with that of Moderna and Pfizer, but it hasn't been rolled out in the broader population yet. In response, MacNeil said that a reaction to one of the mRNA vaccines would necessitate "precaution" when receiving the J&J vaccine, but that it could be done safely if the patient is monitored for at least 30 minutes after receiving the shot. Marci Drees, a liaison to the committee and the chief infection prevention officer at ChristianaCare in Delaware, noted that some of the ingredients of J&J's vaccine are similar to that of the Moderna and Pfizer shots. She added that people who get J&J's should do so "under the supervision of a health-care provider."Ī couple of members of the committee, the expert panel that advises the CDC on immunizations, questioned the CDC's reasoning. The CDC's MacNeil noted that the vaccines "are not interchangeable" and that the safety and efficacy of taking one shot of the Pfizer or Moderna vaccine and one of the J&J vaccine has not been tested. Most of the reactions happen shortly after the first shot, Shimabukuro said. That's a rate, he added, of about 4.7 cases for every million doses of the Pfizer- BioNTech vaccine that's been administered and 2.5 per every million of the Moderna shot. ![]() 18, according to data presented Monday by Dr. Tom Shimabukuro, deputy director of the CDC's Immunization Safety Office. There were 47 reports of anaphylaxis, a severe and life-threatening allergic reaction, among those who received Pfizer's vaccine and 19 cases in those who received Moderna's as of Jan. But J&J's one-shot vaccine, which received emergency use authorization Saturday, could give those patients another way to maximize protection against Covid-19. The CDC currently recommends that people who have a severe allergic reaction to one of the shots forgo the second shot. Janssen makes vaccines and other drugs for J&J. "In exceptional situations where the first dose of an mRNA Covid-19 vaccine was received, but the patient is unable to complete the series with either the same or a different mRNA Covid-19 vaccine, for example due to a contraindication, a single dose of Janssen's Covid-19 vaccine may be administered at a minimum interval of 28 days from the mRNA COVID-19 vaccine dose," she said Monday at an emergency meeting of the CDC's Advisory Committee on Immunization Practices.
