What the medication is used for

Janssen COVID-19 Vaccine is a vaccine used to prevent COVID-19 disease caused by the SARS-CoV-2 virus. Janssen COVID-19 Vaccine can be given to protect people aged 18 years and older.

What it does

Janssen COVID-19 Vaccine uses a recombinant, replication-incompetent human adenovirus type 26 vector to stimulate the body’s natural defenses (immune system) and produce its own protection (antibodies) against the virus. 

The vaccine is given as a single dose, by injection with a needle, usually in the upper arm.

You cannot get COVID-19 from this vaccine.

As with any vaccine, Janssen COVID-19 Vaccine may not fully protect all those who receive it. Even after you have had the vaccine, continue to follow the recommendations of local public health officials to prevent spread of COVID-19.

A single dose (0.5 mL) of Janssen COVID-19 Vaccine should be administered.

In the event of suspected overdose with Janssen COVID-19 Vaccine, contact your regional poison control centre.
Side effects and what to do about them

Like all vaccines, Janssen COVID-19 Vaccine can cause side effects. In clinical studies with the vaccine, most of the side effects, happened within 2 days of getting the injection, were mild to moderate in intensity, and resolved within 1-2 days.

If you experience a severe allergic reaction, call 9-1-1, or go to the nearest hospital.

A combination of blood clots and low level of platelets, in some cases together with bleeding, has been observed very rarely in unusual locations (e.g., brain, liver) following vaccination with Janssen COVID-19 Vaccine. Seek medical attention right away if any of the following symptoms occur within the first month following vaccination:

  • new severe headaches, worsening or persistent headaches; blurred vision, confusion or seizures
  • shortness of breath, chest pain, leg swelling, leg pain or persistent abdominal pain
  • unusual skin bruising or pinpoint round spots under the skin beyond the site of vaccination

Very rare cases of capillary leak syndrome (CLS) have been reported following vaccination with Janssen COVID-19 Vaccine. Some affected patients had a previous diagnosis of CLS. CLS is a serious, potentially fatal condition causing fluid leakage from small blood vessels (capillaries) resulting in rapid swelling of the arms and legs, sudden weight gain and feeling faint (low blood pressure). Seek medical attention right away if you develop these symptoms in the days following vaccination.

Guillain-Barré syndrome (GBS) is a neurological disorder where inflammation of peripheral nerves causes rapid muscle weakness and can sometimes lead to paralysis. This has been reported very rarely after vaccination with Janssen COVID-19 Vaccine. Seek immediate medical attention if you develop weakness and paralysis in the extremities that can progress to the chest and face.

  • allergic reaction, including hives

Should you develop any serious symptoms or symptoms that could be an allergic reaction, seek medical attention immediately. Symptoms of an allergic reaction include:

  • hives (bumps on the skin that are often very itchy)
  • swelling of the face, tongue or throat
  • difficulty breathing

Very rare (may affect up to 1 in 10000 people):

  • persistent ringing in the ears (tinnitus)
  • diarrhea
  • unusual feeling in the skin, such as a persistent tingling feeling (paresthesia)
  • swollen lymph nodes (lymphadenopathy)
  • vomiting
  • decreased feeling or sensitivity, especially in the skin (hypoesthesia)
  • serious nerve inflammation, which may cause paralysis and difficulty breathing (Guillain-Barré syndrome)

These may not be all the possible side effects of Janssen COVID-19 Vaccine. If you experience any side effects not listed here, tell your healthcare professional.
