1. What COVID-19 Vaccine AstraZeneca is and what it is used for
COVID-19 Vaccine AstraZeneca is a vaccine used to protect people aged 18 years and older against
COVID-19 is caused by a virus called coronavirus (SARS-CoV-2).
COVID-19 Vaccine AstraZeneca stimulates the body’s natural defences (immune system). It causes
the body to produce its own protection (antibodies) against the virus. This will help to protect you
against COVID-19 in the future. None of the ingredients in this vaccine can cause COVID-19.
2. What you need to know before you receive COVID-19 Vaccine AstraZeneca
Do not have the vaccine:
 If you have ever had a severe allergic reaction to any of the active substances or any of the other
ingredients listed in section 6. Signs of an allergic reaction may include itchy skin rash,
shortness of breath and swelling of the face or tongue. Contact your doctor or healthcare
professional immediately or go to the nearest hospital emergency room right away if you have
an allergic reaction. It can be life-threatening.
If you are not sure, talk to your doctor, pharmacist or nurse.
Warnings and precautions
Tell your doctor, pharmacist or nurse before vaccination:
 If you have ever had a severe allergic reaction (anaphylaxis) after any other vaccine injection;
 If you currently have a severe infection with a high temperature (over 38°C).
However, a mild fever or infection, like a cold, are not reasons to delay vaccination;
 If you have a problem with bleeding or bruising, or if you are taking a blood thinning medicine
 If your immune system does not work properly (immunodeficiency) or you are taking medicines
that weaken the immune system (such as high-dose corticosteroids, immunosuppressants or
cancer medicines).
If you are not sure if any of the above applies to you, talk to your doctor, pharmacist or nurse before
you are given the vaccine.
As with any vaccine, COVID-19 Vaccine AstraZeneca may not protect everyone who is vaccinated
from COVID-19. It is not yet known how long people who receive the vaccine will be protected for.
No data are currently available in individuals with a weakened immune system or who are taking
chronic treatment that suppresses or prevents immune responses.
Children and adolescents
No data are currently available on the use of COVID-19 Vaccine AstraZeneca in children and
adolescents younger than 18 years of age.

medicines or vaccines.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, tell

AstraZeneca in pregnant or breastfeeding women. Your doctor, pharmacist or nurse will discuss with
you whether you can be given the vaccine.

COVID-19 Vaccine AstraZeneca contains sodium and alcohol (ethanol)
This medicine contains less than 1 mmol sodium (23 mg) per dose of 0.5 ml. This means that it is
essentially ‘sodium-free’.
This medicine contains a very small amount of alcohol (0.002 mg of alcohol (ethanol) per dose of
0.5 ml). This is not enough to cause any noticeable effects.
3. How COVID-19 Vaccine AstraZeneca is given
COVID-19 Vaccine AstraZeneca is injected into a muscle (usually in the upper arm).
You will receive 2 injections. You will be told when you need to return for your second injection
of COVID-19 Vaccine AstraZeneca.
The second injection can be given between 4 and 12 weeks after the first injection.
When COVID-19 Vaccine AstraZeneca is given for the first injection, COVID-19 Vaccine
AstraZeneca (and not another vaccine against COVID-19) should be given for the second injection to
complete vaccination course.
If you miss your second injection
If you forget to go back at the scheduled time, ask your doctor, pharmacist or nurse for advice. It is
important that you return for your second injection of COVID-19 Vaccine AstraZeneca.
