Pfizer website Fridaywill not seek immediate approval for its coronavirus vaccine until the third week of November, the president said in a statement posted on Pfizer’s website Friday.

He is one of 60 health care workers and other medical experts who sent Pfizer a letter urging it to take its time to develop the vaccine, the Times said. Pfizer is one of four companies with a coronavirus vaccine in the final stages of clinical trials in the United States. The company’s withdrawal from previous announcements that it will seek approval in October is a blow to U.S. President Donald Trump, who has repeatedly stated that the vaccine will be available before Election Day in November. Eric Topol, a clinical research specialist with Scripps Research in San Diego, told the Times. Pfizer’s announcement was well received by some scientists. Others were Modern, AstraZeneca and Johnson. Albert Burla said in press release 3, the New York Times reports. “This is good, very good,” Dr. Burla said.
