POTENTIAL SIDE EFFECTS COVID VACCINE - COVID-19 Vaccine Adverse effects & Allergy

COVID-19 vaccines help our bodies develop immunity to the virus that causes COVID-19, without us having to get the illness. Different types of vaccines work in different ways to offer protection, but with all types of vaccines, the body is left with a supply of “memory” T-lymphocytes, B-lymphocytes and antibodies that will remember how to fight that virus in the future.
It typically takes a few weeks for the body to produce T-lymphocytes and B-lymphocytes after vaccination.
Sometimes after vaccination, the process of building immunity can cause symptoms, such as fever, muscle pain, fatigue etc. These symptoms are normal and are a sign that the body is building immunity.
So, it’s very important that you understand the minor side-effects of Covid vaccine and also we will discuss some of the rare but serious complications that can occur.

Vaccines work by introducing a small number of bacteria, virus or toxin into the body. Because the bacteria, virus or toxin have been killed or weakened, there's no risk of contracting the disease in question. However, your body responds as if it were under attack, and mounts an immune response. If, in the future, you do encounter that disease, you'll have an army of cells and antibodies ready to fight it.
