No cases of allergic reactions recorded during Pfizer's COVID-19 vaccine trial - company executive

(Reuters) - There were no cases of severe allergic reactions to Pfizer Inc and partner BioNTech SE's COVID-19 vaccine candidate during clinical trials, a Pfizer executive said at a regulatory conference on Friday. A late-stage trial testing the potential vaccine excluded participants who had a prior history of severe allergic reactions to any vaccine or to the constituents of Pfizer/BioNTech vaccine, said Dr. William Gruber, Pfizer's senior vice president of vaccine clinical research and development.

(Reuters) - There were no cases of severe allergic reactions to Pfizer Inc and partner BioNTech SE's COVID-19 vaccine candidate during clinical trials, a Pfizer executive said at a regulatory conference on Friday.

A late-stage trial testing the potential vaccine excluded participants who had a prior history of severe allergic reactions to any vaccine or to the constituents of Pfizer/BioNTech vaccine, said Dr. William Gruber, Pfizer's senior vice president of vaccine clinical research and development.

"We've not had any anaphylactic episodes related to the vaccine," Gruber said during a panel meeting of independent advisers to the U.S. Centers for Disease Control and Prevention.

The trial included about 6,000 participants respectively in both the vaccine and placebo groups with a history of a range of allergic conditions like pollen allergy, food allergy, all the way up to anaphylaxis, Pfizer executive Susan Mather said.

Anaphylaxis is an overreaction by the body's immune system that could sometimes be life-threatening.

The comments follow British medicine regulator's advice that people with a history of significant allergic reactions do not get the Pfizer-BioNTech's vaccine after two people reported adverse effects.

The U.S. Food and Drug Administration is expected to issue an emergency use authorization for the two-dose vaccine as soon as Friday, according to the New York Times.

Once authorized, the first Americans could be immunized as soon as Monday or Tuesday, with healthcare workers expected to be among the first in line.

"The question is whether this just a symbolic gesture to the United States

China's Xi says navy should become world class | Reuters

BEIJING Chinese President Xi Jinping on Wednesday called for greater efforts to make the country's navy a world class one, strong in operations on, below and above the surface, as it steps up its ability to project power far from its shores.China's navy has taken an increasingly prominent role in recent months, with a rising star admiral taking command, its first aircraft carrier sailing around self-ruled Taiwan and a new aircraft carrier launched last month.With President Donald Trump promising a US shipbuilding spree and unnerving Beijing with his unpredictable approach on hot button issues including Taiwan and the South and East China Seas, China is pushing to narrow the gap with the U.S. Navy.Inspecting navy headquarters, Xi said the navy should "aim for the top ranks in the world", the Defence Ministry said in a statement about his visit."Building a strong and modern navy is an important mark of a top ranking global military," the ministry paraphrased Xi as saying.
