But Pfizer has received no support from the US government beyond a $ 1.95 billion deal to buy 100 million initial doses. No money is paid until the vaccine is approved.
Pfizer’s head of vaccine research and development, Dr. Kathrin Jansen, told the New York Times that the team was “never part of Warp Speed”.
“We have never received money from the United States government or anyone,” he said.
A Pfizer spokesperson later clarified that the company is part of Operation Warp Speed as a supplier of a possible coronavirus vaccine.
American epidemiologist Dr. Eric Feigl-Ding responded to Trump’s tweet, saying that while the news that this experimental vaccine is 90 percent effective is exciting, it is still early.
“It’s just the results for the first seven days. The Pfizer vaccine also needs a subsequent booster injection. Therefore, seven days is not enough data. We need longer trial data on the efficacy and safety of COVID-19.” said.
“In addition, Pfizer’s vaccine also needs deep freezing and cold chain in transport / storage, which is logistically expensive / risky … And the cold chain is risky – any failure to keep the test tube vials frozen for a few minutes it would mean the vaccine will not be as effective.
“And I hate to tell you Ivanka Trump, Pfizer was never really part of Operation Warp Speed.”
