Johnson & Johnson Announces Positive CHMP Opinion for a Booster Shot of its COVID-19 Vaccine

CHMP recommendation based on data showing a booster (second shot) of the Johnson & Johnson COVID-19 vaccine increased protection to 75 percent against symptomatic COVID-19 infection globally

Data also demonstrated 100 percent protection against severe COVID-19, at least 14 days post-booster vaccination

The Johnson & Johnson COVID-19 vaccine, when given as a booster or primary shot, was generally well-tolerated

NEW BRUNSWICK, N.J., Dec. 15, 2021 /PRNewswire/ -- Johnson & Johnson (NYSE: JNJ) (the Company) today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) issued a Positive Opinion for use of the Company's COVID-19 vaccine as a booster for adults aged 18 and older at least two months after primary vaccination with a single-shot of the Johnson & Johnson COVID-19 vaccine, and as a 'mix and match' booster following primary vaccination with an approved two-shot mRNA COVID-19 vaccine regimen (known as heterologous boosting).

"We are pleased with today's Positive Opinion from the CHMP supporting the use of our COVID-19 vaccine as a booster for eligible individuals in Europe," said Mathai Mammen, M.D., Ph.D., Global Head, Janssen Research & Development, Johnson & Johnson. "There is a growing body of data showing that the Johnson & Johnson COVID-19 vaccine induces broad and durable humoral and cellular immune responses, whether administered as a single shot for an efficient response to the pandemic, or as a booster shot after at least two months to strengthen protection against symptomatic COVID-19. Cellular immune responses are showing potential to be important for both breadth of protection and durability."

The CHMP Opinion was based on a comprehensive data package that included results from the Phase 3 ENSEMBLE 2 study, which found a booster of the Johnson & Johnson COVID-19 vaccine given two months after the primary shot provided 75 percent protection against symptomatic (moderate to severe) COVID-19 globally (CI, 55%-87%) and 94 percent protection against symptomatic (moderate to severe) COVID-19 in the U.S. (CI, 59%-100%). It also demonstrated 100 percent protection against severe COVID-19, at least 14 days post-booster vaccination (CI, 33%-100%). The vaccine, when given as a booster or primary shot, was generally well-tolerated, with no new safety signals observed in the two-shot ENSEMBLE 2 trial compared with single-shot studies. 

Also included in the data package reviewed by the CHMP were results from multiple real-world evidence (RWE) studies, including the Company's previously announced RWE study that demonstrated similar estimates of single-shot vaccine effectiveness as observed in our randomized clinical trials. The effectiveness estimates remained stable with no evidence of reduced effectiveness over time before the Delta variant emerged and after it became the dominant strain in the U.S. from March through August (sequencing data were not available for analysis).

The CHMP recommendation is supported by latest data for heterologous boosting with the Johnson & Johnson COVID-19 vaccine. Interim data from the National Institute of Allergy and Infectious Disease (NIAID) "MixNMatch" study demonstrated that a booster of the Johnson & Johnson COVID-19 vaccine increases immune response regardless of a person's primary vaccination. A second study by the Beth Israel Deaconess Medical Center (BIDMC), including a subset of participants from the Janssen-sponsored COV2008 study, demonstrated the potential benefits of heterologous boosting: a booster shot of the Johnson & Johnson vaccine administered at six months after a two-shot primary regimen of the Pfizer/BioNTech vaccine, increased both antibody and T-cell responses. In these participants, antibodies continued to increase for at least four weeks whereas in individuals who received a homologous boost with the BNT162b2 vaccine, antibodies declined from week two to week four post-boost, resulting in similar antibody levels in both groups.

The Company's single-shot COVID-19 vaccine, developed by its Janssen Pharmaceutical Companies of Johnson & Johnson, received an Emergency Use Authorization in the United States on 27 February 2021 and Conditional Marketing Authorisation (CMA) by the European Commission on 11 March. On 21 October 2021, the U.S. Centers for Disease Control and Prevention (CDC) Advisory Committee on Immunization Practices (ACIP) authorized for emergency use a booster shot of the Johnson & Johnson COVID-19 vaccine for adults aged 18 and older. On 9 December 2021, the Strategic Advisory Group of Experts (SAGE) on Immunization for the World Health Organization (WHO) supported the use of the Johnson & Johnson COVID-19 vaccine as a heterologous booster shot in persons aged 18 years and above.

• Persistent ringing in the ears (tinnitus).
• Diarrhea, vomiting.

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:

• Difficulty breathing
• Swelling of your face and throat
• A fast heartbeat
• A bad rash all over your body
• 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 after vaccination. Blood clots with low levels of platelets following the Janssen COVID-19 Vaccine have been reported in males and females, across a wide age range of individuals 18 years and older; reporting has been highest in females ages 30 through 49 years (about 1 case for every 100,000 vaccine doses administered), and about 1 out of every 7 cases has been fatal. You should seek medical attention right away if you have any of the following symptoms after receiving the Janssen COVID-19 Vaccine:

• Shortness of breath,
• Chest pain,
• Leg swelling,
• Persistent abdominal pain,
• Severe or persistent headaches or blurred vision,
• Easy bruising or tiny blood spots under the skin beyond the site of the injection.

These may not be all the possible side effects of the Janssen COVID-19 Vaccine. Serious and unexpected effects may occur. The Janssen COVID-19 Vaccine is still being studied in clinical trials.

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.
• Difficulty with bladder control or bowel function.
