A similar mRNA vaccine developed by Moderna, which was authorized for emergency use in the United States on Friday, also contains the compound, polyethylene glycol (PEG). .......Anaphylactic reactions can occur with any vaccine, but are usually extremely rare—<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4783279/" target="_blank">about one per 1 million doses</a>. As of 19 December, the United States had seen six cases of anaphylaxis among 272,001 people who received the COVID-19 vaccine, according to a <a href="https://www.cdc.gov/vaccines/acip/meetings/downloads/slides-2020-12/slides-12-19/05-COVID-CLARK.pdf" target="_blank">recent presentation</a> by Thomas Clark of the U.S. Centers for Disease Control and Prevention (CDC); <a href="https://www.gov.uk/government/news/confirmation-of-guidance-to-vaccination-centres-on-managing-allergic-reactions-following-covid-19-vaccination-with-the-pfizer-biontech-vaccine" target="_blank">the United Kingdom has recorded two</a>. Because the Pfizer and Moderna mRNA vaccines use a new platform, the reactions call for careful scrutiny, says Elizabeth Phillips, a drug hypersensitivity researcher at Vanderbilt University Medical Center who attended an NIAID meeting on 16 December. “This is new.”</blockquote>
