The chief government of Pfizer said on Friday that the corporate wouldn’t apply for emergency authorization of its coronavirus vaccine earlier than the third week of November, ruling out President Trump’s assertion {that a} vaccine can be prepared earlier than Election Day on Nov. 3.

In an announcement posted to the corporate web site, the chief government, Dr. Albert Bourla, mentioned that though Pfizer may have preliminary numbers by the top of October about whether or not the vaccine works, it might nonetheless want to gather security and manufacturing information that can stretch the timeline to a minimum of the third week of November.

Close watchers of the vaccine race had already known that Pfizer wouldn’t have the ability to meet the necessities of the Food and Drug Administration by the top of this month.

Keep up with Election 2020

He mentioned firm officers had assured him {that a} vaccine would most probably not be approved earlier than the election, however the letter Friday is “even more solid about their not being part of any political machinations.”

Dr. Bourla has pushed again towards any suggestion that Pfizer’s vaccine timeline was politically motivated. In September, Pfizer was the driving drive behind a pledge by 9 vaccine firms to “stand with science” and never put ahead something that had not been correctly vetted. Earlier this month, he published an open letter to employees that mentioned he “would never succumb to political pressure” and expressing disappointment that “we find ourselves in the crucible of the U.S. presidential election.”

Pfizer is certainly one of 4 firms testing a coronavirus vaccine in late-stage medical trials within the United States, and it has been the most aggressive in its timeline estimates. Moderna, AstraZeneca and Johnson & Johnson have mentioned that later within the 12 months is extra possible, matching the predictions of federal well being officers. (AstraZeneca and Johnson & Johnson’s trials have been paused for potential safety concerns, which may additional delay their outcomes.)

In interviews, Mr. Bourla has mentioned that he expects a “conclusive readout” by late October, with an utility for emergency authorization that may very well be filed “immediately.”

Pfizer’s trial of 44,000 volunteers assessments the vaccine by giving one group the vaccine, one other group the placebo, and ready till a sure variety of folks change into contaminated with the virus. If considerably extra individuals who obtained the placebo obtained contaminated, then the vaccine is taken into account to be efficient.

An organization spokeswoman mentioned final month that Pfizer wouldn’t be wherever close to completion of its trial by the top of October and that when Dr. Bourla had referred to a “conclusive readout,” he meant it was doable the skin board of consultants monitoring the trial would have by that date discovered promising indicators that the vaccine works.

In his assertion on Friday, Dr. Bourla acknowledged these timelines have been unsure. “Since we must wait for a certain number of cases to occur, this data may come earlier or later based on changes in the infection rates.”

He additionally mentioned the corporate would launch the outcomes of any resolution by the skin panel — good or dangerous — inside just a few days of its resolution.

Dr. Bourla’s assertion arrived quickly after the F.D.A. revealed new pointers detailing how the company would consider a vaccine for emergency authorization, a doc published after weeks of stalling by the White House. The pointers, which don’t carry the drive of legislation, name for gathering complete security information within the ultimate stage of medical trials earlier than an emergency authorization will be granted.

In a tweet on Oct. 6, Mr. Trump accused the F.D.A. of getting a political agenda with the suggestions, which he mentioned “make it more difficult for them to speed up vaccines for approval before Election Day.” Mr. Trump referred to as it a “political hit job.”

In a video he posted from the White House a day later, Mr. Trump said {that a} vaccine ought to be accessible earlier than the election, “but frankly, the politics gets involved.”

“They want to play their games,” he mentioned. “It’s going to be right after the election.”
