The U.S. Food and Drug Administration (FDA) recently issued an Emergency Use Authorization (EUA) for Johnson & Johnson’s COVID-19 vaccine to be distributed in the United States for use by individuals 18 years of age and older.
According to the FDA, the
effectiveness data to support its EUA includes an analysis of participants who
did not have evidence of SARS-CoV-2 infection prior to receiving the vaccine.
This ongoing study is being conducted in South Africa, certain countries in
South America, Mexico and the United States. Overall, the vaccine was found to
be approximately 67% effective in preventing moderate to severe COVID-19 cases
occurring at least 14 days after vaccination and 85% effective in preventing
moderate to severe COVID-19 cases occurring at least 28 days after vaccination.
Additionally, the FDA has not identified any specific safety concerns, and the
agency says the vaccine meets its rigorous standards for safety.
Overview of the Johnson & Johnson COVID-19
Vaccine
The Johnson &
Johnson COVID-19 vaccine was developed by Janssen Biotech Inc., a
subsidiary of Johnson & Johnson, and importantly, requires only one dose, as opposed to the Moderna and
Pfizer-BioNTech vaccines which require two doses. The vaccine can also be
stored at standard refrigeration temperatures for at least three months, while other
vaccines approved for emergency use have stricter refrigeration and storage
requirements.
Next Steps
There are around 4 million doses of this vaccine ready to be
distributed, and shipments of the
vaccine are set to begin immediately. Distribution of the vaccine could begin
as soon as Tuesday, March 2. Johnson & Johnson plans on providing up
to 20 million shots in the next month and 100 million over the summer.
