Facts and Figures you need to know about Covid-19 Vaccine Part 1
1. How do vaccines prevent disease?
Vaccines mimic the virus or bacteria that causes disease and triggers the body’s creation of antibodies. These antibodies will provide protection once a person is infected with the actual disease-causing virus or bacteria.
2. How do vaccines differ?
Vaccines differ in their composition and how they trigger the immune response to create antibodies. These antibodies protect the body from microorganisms and serve as protection once a person gets infected with disease. Vaccines can be inactivated, weakened or killed copies of the whole or part of the virus or bacteria, or genetic product (like mRNA vaccines) that creates protein copies without causing disease.
3. What are the possible side effects of vaccination?
The possible side effects of a vaccine include pain, redness, itchiness or swelling at the injection site (which may last a few hours); fever; feeling of weakness or fatigue; headache; dizziness; diarrhea; or nausea. Consult the nearest healthcare professional if you experience any of these.
