When the UK began inoculating people with the coronavirus vaccine developed by Pfizer-BioNTech, four volunteers who were given the vaccine at the trial stage developed Bell’s palsy, according to Food Administration regulators. and US Drugs (FDA). Bell’s palsy is a form of temporary facial palsy.
However, regulators at the US FDA noted that it was not yet clear how Bell’s palsy was caused in these volunteers by the Pfizer vaccine. US regulators stressed that doctors should closely monitor the vaccine’s side effects and continue to watch how many people it attacks.
The person suffering from Bell’s palsy develops temporary weakness or paralysis of the facial muscles. Paralysis usually occurs when a nerve that controls muscles becomes inflamed, swollen, or compressed.
Meanwhile, Pfizer CEO Albert Bourla noted on Wednesday (Dec. 9) that the pharmaceutical giant “spared no effort” while launching the vaccines.
The vaccine “has been tested in exactly the same way that we are testing any vaccine that is out there,” Bourla said, adding that “this vaccine was actually tested, due to scrutiny, to even higher standards in terms of how to do things. “
“There are always people who are skeptical about vaccines, but I have to say they are wrong,” said the Pfizer CEO.
Earlier, the UK drug regulator warned that people with a history of major allergic reactions should avoid getting the Pfizer vaccine after two people reported adverse effects.
National Health Service Medical Director Stephen Powis said two NHS workers reported anaphylactoid reactions after getting vaccinated.
“As is common with new vaccines, the MHRA (regulator) has advised as a precaution that people with a significant history of allergic reactions should not receive this vaccine, after two people with a history of significant allergic reactions responded adversely yesterday “Powis said. .
