Submission includes data showing a booster increased protection to 94 percent against moderate to severe/critical COVID-19 in the U.S.
Substantial increase in immune response when booster was given at six months
The Company’s single-shot vaccine has demonstrated strong and long-lasting protection and durable immune responses in clinical studies
NEW BRUNSWICK, N.J., October 5, 2021 – Johnson & Johnson (NYSE: JNJ) announced it has submitted data to the U.S. Food and Drug Administration (FDA) to support use of a booster shot of the Johnson & Johnson COVID-19 vaccine in individuals 18 years of age and older.
The submission includes recent results from the Phase 3 ENSEMBLE 2 study that found a booster of the Johnson & Johnson COVID-19 vaccine given 56 days after the primary dose provided 94 percent protection against symptomatic (moderate to severe/critical) COVID-19 in the U.S. (CI, 58%-100%) and 100 percent protection (CI, 33%-100%) against severe/critical COVID-19, at least 14 days post-booster vaccination.
Also part of the submission is Phase 1/2a data showing that when a booster of the Johnson & Johnson COVID-19 vaccine was given six months after the single shot, antibody levels increased nine-fold one week after the booster and continued to climb to 12-fold higher four weeks after the booster. The vaccine, when given as a booster or primary dose, was generally well-tolerated.
“Our clinical program has found that a booster of our COVID-19 vaccine increases levels of protection for those who have received our single-shot vaccine to 94 percent. We look forward to our discussions with the FDA and other health authorities to support their decisions regarding boosters,” said Mathai Mammen, M.D., Ph.D., Global Head, Janssen Research & Development, Johnson & Johnson. “At the same time, we continue to recognize that a single-shot COVID-19 vaccine that provides strong and long-lasting protection remains a crucial component to vaccinating the global population.”
Last month, the Company released data reinforcing the strong and long-lasting protection of its COVID-19 vaccine. The largest real-world evidence study for a COVID-19 vaccine reported to date in the U.S. demonstrated stable vaccine effectiveness of 79 percent (CI, 77%-80%) for COVID-19-related infections and 81 percent (CI, 79%-84%) for COVID-19-related hospitalizations. There was no evidence of reduced effectiveness over the study duration from March to July 31, 2021. Comparable vaccine effectiveness was demonstrated when the study was extended to August 31, 2021, for an overall study duration of six months, including when the Delta variant became dominant in the U.S. Sequencing data were not available for analysis.
These data were consistent with the Phase 3 ENSEMBLE trial, where strong protection against severe/critical disease and death was observed at least 28 days post-final vaccination.
Interim results from a Phase 1/2a sub-study published in the New England Journal of Medicine in July demonstrated that both humoral (antibody) and cellular (T-cell) immune responses generated by the Johnson & Johnson single-shot COVID-19 vaccine were strong and stable through eight months after immunization, the length of time evaluated in the study. These peer-reviewed data provide further and deeper insights into the durable humoral and cellular immune responses elicited by the single-shot Johnson & Johnson COVID-19 vaccine, thus offering potentially a dual mechanism of protection against COVID-19 disease, including against disease caused by the Delta variant (B.1.617.2) and other SARS-CoV-2 variants of concern. The cellular immune response induced by the Company’s AdVac® platform is strong and plays a role in both protection and durability.
The Company plans to submit the data to other regulators, the World Health Organization (WHO) and National Immunization Technical Advisory Groups (NITAGs) worldwide to inform decision-making on local vaccine administration strategies, as needed.
The Johnson & Johnson single-shot COVID-19 vaccine, developed by its Janssen Pharmaceutical Companies of Johnson & Johnson, received an EUA in the United States on February 27, 2021 and Conditional Marketing Authorization (CMA) by the European Commission on March 11. The World Health Organization (WHO) issued Emergency Use Listing on March 12, and the Company received an interim recommendation by the Strategic Advisory Group of Experts (SAGE) on Immunization for the WHO on March 17. Many more authorizations have been granted in countries worldwide, and regulatory submissions are ongoing.

The Janssen COVID-19 vaccine is authorized for use in the U.S. under an Emergency Use Authorization (EUA) for active immunization to prevent coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in individuals 18 years of age and older.

- have ever fainted in association with an injection
WHO SHOULD NOT GET THE JANSSEN COVID-19 VACCINE?
You should not get the Janssen COVID-19 Vaccine if you:
- had a severe allergic reaction to any ingredient of this vaccine.
HOW IS THE JANSSEN COVID-19 VACCINE GIVEN?
The Janssen COVID-19 Vaccine will be given to you as an injection into the muscle. The Janssen COVID-19 Vaccine vaccination schedule is a single dose.

Severe Allergic Reactions
There is a remote chance that the Janssen COVID-19 Vaccine could cause a severe allergic reaction. A severe allergic reaction would usually occur within a few minutes to one hour after getting a dose of the Janssen COVID-19 Vaccine. For this reason, your vaccination provider may ask you to stay at the place where you received your vaccine for monitoring after vaccination. Signs of a severe allergic reaction can include:

- Dizziness and weakness
Blood Clots with Low Levels of Platelets
Blood clots involving blood vessels in the brain, lungs, abdomen, and legs along with low levels of platelets (blood cells that help your body stop bleeding), have occurred in some people who have received the Janssen COVID-19 Vaccine. In people who developed these blood clots and low levels of platelets, symptoms began approximately one to two weeks following vaccination. Reporting of these blood clots and low levels of platelets has been highest in females ages 18 through 49 years. The chance of having this occur is remote. You should seek medical attention right away if you have any of the following symptoms after receiving Janssen COVID-19 Vaccine:
- Shortness of breath
- Chest pain
- Leg swelling

Guillain Barré Syndrome
Guillain Barré syndrome (a neurological disorder in which the body’s immune system damages nerve cells, causing muscle weakness and sometimes paralysis) has occurred in some people who have received the Janssen COVID-19 Vaccine. In most of these people, symptoms began within 42 days following receipt of the Janssen COVID-19 Vaccine. The chance of having this occur is very low. You should seek medical attention right away if you develop any of the following symptoms after receiving the Janssen COVID-19 Vaccine:
- Weakness or tingling sensations, especially in the legs or arms, that’s worsening and spreading to other parts of the body
- Difficulty walking
- Difficulty with facial movements, including speaking, chewing, or swallowing
- Double vision or inability to move eyes
