A healthcare worker in Alaska was hospitalized on Tuesday with a “ severe allergic reaction ” after receiving Pfizer’s COVID-19 vaccine, according to the New York Times.
The person, who had no known allergy to the drugs, was still in the hospital Wednesday morning under observation, according to the report. It is not known if they have other types of allergies. The reaction of the residents of Alaska was apparently similar to the anaphylactic reactions two workers recover from in Britain after receiving the Pfizer-BioNTech vaccine last week – who both recovered. Note, they both had a history of severe allergies. One, a 49-year-old woman, is allergic to eggs (which Pfizer says are do not in their vaccine). The other, a 40-year-old woman, is allergic to several different drugs. Both systematically wear EpiPenn-type devices in the event of reactions.
After British workers fell ill, authorities initially warned against administering the vaccines to anyone with a history of severe allergic reactions. They later clarified their concerns, changing the wording from “severe allergic reactions” to make it clear that the vaccine should not be given to anyone who has had an anaphylactic reaction to any food, drug or vaccine in the past. This type of reaction to a vaccine is “very rare,” they said. –NYT
No serious side effects were reported in Pfizer’s US trial involving over 40,000 participants, apart from body aches, fever and other “minor” side effects.
Headaches all around
As Bloomberg note, the first hiccup in the delivery of the Pfizer vaccine has only just begun – including a delay in delivering 3,900 injections to two states, and the announcement that around 900,000 fewer doses would be delivered next week than had been shipped this week.
Four Pfizer-BioNTech SE vaccine delivery trays were pulled from delivery to California and Alabama this week and returned to the company because they were colder than expected, according to Gustave Perna, the army general who is the head of operations for Operation Warp Speed.
Each of the trays can probably be used to vaccinate 975 people. Pfizer said its formula should be stored at 70 degrees below zero Celsius, the equivalent of minus 94 degrees below zero Fahrenheit. Those plateaus turned out to be much cooler, according to Perna. –Bloomberg
“We weren’t taking any risks,” Perna said at a press briefing on Wednesday.
Pfizer doses are shipped in temperature-controlled containers developed by the company’s engineers, each equipped with GPS tracking “for real-time, continuous temperature tracking and tracking,” according to the company.
Meanwhile, around 2 million doses of the Pfizer vaccine will be shipped to the United States next week, 900,000 less than the 2.9 million doses available this week. Health and Human Services Secretary Alex Azar acknowledged the production hiccups, saying: “As you know they ended up running out of half of what they thought they could produce and what they did. had announced that they would be able to produce “in 2020.
“They are currently producing at maximum capacity to deliver the $ 100 million that is in the first installment of the contract with us, and we are providing manufacturing support,” added Azar.
And on Tuesday, Florida Governor Ron DeSantis said shipments of hundreds of thousands of doses have been blocked due to a “production problem with Pfizer”.
The company fired back, spokeswoman Amy Rose saying the company “has not had any production issues with our COVID-19 vaccine, and no shipments containing the vaccine are pending or delayed,” adding: locations specified by the US government. “
