Public Release of Clinical Information - COVISHIELD
This information was provided by the drug’s manufacturer when this drug product was approved for sale in Canada. It is designed for consumers and care givers. It is a summary of information about the drug and will not tell you everything about the drug. Contact your doctor or pharmacist if you have any questions about the drug.
What the medication is used for
COVISHIELD is a vaccine used to prevent the coronavirus disease 2019 (COVID-19) caused by the SARS-CoV-2 virus. It can be given to adults 18 years of age and older.
What it does
COVID-19 is caused by a virus called coronavirus (SARS-CoV-2).
COVISHIELD stimulates the body’s natural defences (immune system), by causing the body to produce its own protection (antibodies) against the SARS-CoV-2 virus that causes the COVID-19 infection. You cannot get COVID-19 from this vaccine.
The vaccine is given by injection with a needle usually in the upper arm, and will require two doses given between 4 and 12 weeks apart. Individuals may not be optimally protected until after receiving the second dose of the vaccine. As with any vaccine, COVISHIELD may not fully protect all those who receive it. It is not yet known how long people who receive the vaccine will be protected.
Even after you have had both doses of the vaccine, continue to follow the recommendations of local public health officials to prevent spread of COVID-19.

You should not receive COVISHIELD if you:
- Had a severe allergic reaction to any of the medicinal ingredients or any of the other ingredients in this vaccine (see What the medicinal ingredient is and What the non-medicinal ingredients are). If you are not sure, talk to your healthcare professional;
- Have had an allergic reaction to a previous dose of COVISHIELD/AstraZeneca COVID-19 Vaccine;
- Have had a major blood clot occurring at the same time as having low levels of platelets (thrombocytopenia) after receiving COVISHIELD/ AstraZeneca COVID-19 Vaccine;
- Have previously experienced episodes of capillary leak syndrome (see Side effects and what to do about them);
- Have any symptoms that could be due to COVID-19. Talk with your healthcare professional about your symptoms and getting a COVID-19 test. Your healthcare professional will advise you when you are able to receive the vaccine.

- Have had a history of venous sinus thrombosis in the brain (CVST) with low blood platelets (thrombocytopenia) or a history of heparin-induced thrombocytopenia (HIT);
- Have had previously experienced episodes of capillary leak syndrome (see Side effects and what to do about them);

COVISHIELD has no known effect on the ability to drive and use machines. However, side effects listed in Side effects and what to do about them may impact your ability to drive and use machines. If you feel unwell, do not drive or use machines.
Interactions with this medication
Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.
Tell your healthcare professional if you are taking, have recently taken or might take, any other medicines or vaccines.
Proper use of this medication
How COVISHIELD is given:
- A healthcare provider will inject the vaccine into a muscle (intramuscular injection), usually in your upper arm.
- During and after each injection of the vaccine, your doctor, pharmacist or nurse will watch over you for around 15 minutes to monitor for signs of an allergic reaction.
You will receive 2 injections. You will be told when you need to return for your second injection.
The second injection can be given between 4 and 12 weeks after the first injection.
It is very important that you return for the second injection, or the vaccine may not work as well.
Individuals should complete the vaccination course with either COVISHIELD or AstraZeneca COVID-19 Vaccine.
If you forget to go back to your healthcare professional at the scheduled time for your next dose, ask your healthcare professional for advice. It is important that you return for your second injection.
Side effects and what to do about them
Like all medicines, COVISHIELD can cause side effects, although not everybody gets them. Most side-effects are mild to moderate in nature and resolve within a few days. Fewer side effects are reported after the second dose.
Severe allergic reaction (anaphylaxis), severe swelling of the lips, mouth, throat (which may cause difficulty in swallowing or breathing) have been reported following COVISHIELD and/or AstraZeneca COVID-19 Vaccine. Should you develop any serious symptoms or symptoms that could be an allergic reaction, seek medical attention right away. Symptoms of an allergic reaction include:
- hives (bumps on the skin that are often very itchy)
- feeling faint or light-headed
- changes in your heartbeat
- swelling of your face, lips, tongue or throat
- difficulty breathing, shortness of breath or wheezing
A combination of blood clots and low level of platelets, in some cases together with bleeding, have been observed very rarely following vaccination with COVISHIELD and/or AstraZeneca COVID-19 Vaccine in post-authorization use. The majority of the cases occurred within the first 3 weeks following vaccination and some cases had a fatal outcome. Very rare cases of low blood platelets (thrombocytopenia) have also been reported. 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 beyond the site of vaccination.
After vaccination, you may have more than one side effect at the same time (for example, muscle/joint aches, headaches, chills and generally feeling unwell). If any of your symptoms are persistent, please seek advice from your healthcare professional.
Very rare cases of capillary leak syndrome (CLS) have been reported following vaccination with COVISHEILD and/or AstraZeneca 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.
Side effects that have been reported with COVISHIELD were as follows:
Very Common (may affect more than 1 in 10 people)
- tenderness, pain, warmth or itching where the injection is given
