Two people in the UK had similar reactions, leading the government to advise against taking the vaccine in the event of a history of severe allergies.
An Alaskan health professional suffered a severe allergic reaction after receiving the Covid-19 vaccine from Pfizer-BioNTech and is now hospitalized but stable, according to a report released Wednesday (16).
The New York Times reported that the man received his dose on Tuesday, while Pfizer confirmed that it was working with local authorities to investigate the incident.
“We do not yet have full details of the Alaska report on possible serious allergic reactions, but we are actively working with local health officials to evaluate” the case, a Pfizer spokesman said.
“We will closely monitor all reports suggesting serious allergic reactions after vaccination and update the label text if necessary,” he added.
The volunteers who showed up for the Pfizer clinical study, a total of 44,000 people, were excluded if they had a history of allergic reactions to the Covid-19 vaccines or immunizer components.
Overall, the tests found no serious safety concerns, but regulators and the company continue to monitor adverse cases after vaccination.
Two healthcare workers in the UK had similar allergic reactions, prompting the European country’s government to advise the public to avoid getting the vaccine if they have a history of severe allergies.
The US food and drug regulatory agency, the FDA, has issued an emergency authorization for the vaccine on the condition that people who have been allergic to its components should avoid it.
The United States this week began giving the vaccine to about three million people and expects to reach a total of 20 million by December if another immunizer, the one developed by the American laboratory Moderna, is approved.
