4. How do vaccines work?
Vaccines help train our immune system to fight infections by introducing an inactivated form of a germ (bacteria or virus) into the body. Since it is inactivated, it cannot make us sick. However, it triggers our body’s immune system to produce defences called antibodies. Then, if you ever catch the germ, your body’s immune system will already know how to fight it.
5. Where can I find the latest guidance on vaccinations?
Contact your health care provider, consult your local and national health authority websites and follow guidance provided by WHO and UNICEF.
6. How can I protect myself and others from COVID-19?
Some of the precautions you and your family can take to help avoid infection include:
- Washing your hands frequently using soap and water or an alcohol-based hand rub.
- Avoid touching your face, especially your eyes, nose and mouth.
- If you sneeze or cough, cover mouth and nose with flexed elbow or a tissue. Dispose of used tissue immediately.
- Avoid crowded places and close contact with people. Keep a safe distance from anyone who has cold or flu-like symptoms.
- Avoid shaking hands, hugging or kissing people.
- Avoid sharing food, utensils, cups and towels.
- Clean and disinfect surfaces that are touched a lot, including phones, doorknobs, light switches, remote controls and countertops.
- Stay at home if you feel unwell, even with a slight fever and cough.
- Wear a mask if you are coughing or sneezing or taking care of someone who is suspected to have COVID-19. Healthcare workers should wear medical masks.
