The drugmaker's application to the U.S. Food and Drug Administration
(FDA) follows its Jan. 29 report in which it said the vaccine had a
66% rate of preventing infections in its large global trial.
The FDA said on Thursday evening that it has scheduled a meeting of
its Vaccines and Related Biological Products Advisory Committee on
Feb. 26, to discuss the company's request for emergency use
authorization. (https://bit.ly/3oRgha3)
Vaccines from Pfizer Inc/BioNTech SE and Moderna Inc were authorized
a day after such a meeting.
J&J's single-shot vaccine could help boost supply and simplify the
U.S. immunization campaign, amid concerns of fresh surges due to the
more contagious UK coronavirus variant and the potential of lower
vaccine efficacy against a variant that first emerged in South
Africa.
Unlike the two currently authorized vaccines from Pfizer/BioNTech SE
and Moderna, J&J's does not require a second shot or need to be
shipped frozen.
After the company's application, regulators will need time to
analyze the data and an advisory committee must meet. The company's
chief scientific officer, Paul Stoffels, said last month J&J was on
track to roll out the vaccine in March.
"Upon authorization of our investigational COVID-19 vaccine for
emergency use, we are ready to begin shipping," Stoffels said in a
statement announcing the application.
J&J said it had rolling submissions with several global health
agencies and would submit a Conditional Marketing Authorization
Application with the European Medicines Agency in the coming weeks.
J&J's application raised hopes for fighting a pandemic that has
claimed more than 451,145 American lives and over 2,271,152
worldwide.
Shares of Johnson & Johnson rose about 1% in extended trading on
Thursday, while Moderna was down 0.7% and Pfizer stock was little
changed.

The United States has agreed to
pay $1 billion for 100 million doses, which J&J
said it expected to supply in the first half of
the year. The United States also has the option
of purchasing an additional 200 million doses.
The company said it has doses ready for delivery
upon emergency approval. It aims to deliver 1
billion doses in 2021 with production in the
United States, Europe, South Africa and India.
In J&J's trial of nearly 44,000 volunteers conducted in eight
countries, the level of protection against COVID-19 was 72% in the
United States, 66% in Latin America and 57% in South Africa where
variants are circulating.
Those results compare with the 95% effectiveness of the two-dose
vaccines made by Pfizer/BioNTech SE and Moderna.
However, both those trials were conducted mainly in the United
States and before the spread of new variants.
J&J's main study goal was the prevention of moderate to severe
COVID-19, and the vaccine was 85% effective in stopping severe
disease and preventing hospitalization across all geographies and
against multiple variants 28 days after immunization.
J&J's vaccine uses a common cold virus known as adenovirus type 26
to introduce coronavirus proteins into cells in the body and trigger
an immune response.
The Pfizer/BioNTech and Moderna vaccines use a new technology called
messenger RNA (mRNA) that requires it to be stored in a freezer.
