Why there are the side effects of the covid 19 vaccine

An allergist, immunologist, and president of the American Medical Association. Susan R. Bailey said, "Side effects develop because the immune system reacts to the covid 19 vaccines. Fever, fatigue, and headache occur 12 to 24 hours after vaccination."

 The COVID-19 mRNA vaccine tells the body to make the "SPIKE" protein of the coronavirus, which the virus uses to enter and infect cells. (JHONSON and ASTROJENICA covid 19 vaccines introduce spike proteins through weak common cold viruses.) These spike proteins are present in three types of cells from macrophages, T cells, and B cells. Macrophages are the first of these cells to detect and eliminate harmful organisms, on the other hand, by transferring them to the T cell region where the covid 19 vaccine was administered to help remember the coronavirus spike protein for future encounters. Once the covid 19 vaccines are recognized as a foreigner, B cells begin to form an army of antibodies.

 All of these immune cells produce inflammatory proteins known as cytokinesis. Cytokines are a type of chemical messenger that helps coordinate the immune response. A common side effect of the COVID-19 vaccine is that it makes the body less hostile to the virus at higher temperatures and stimulates the body to produce more immune cells by raising the temperature. This inflammatory chemical can cause muscle pain, fatigue, headaches, and other symptoms.

 The COVID-19 vaccine provides adequate amounts of spike protein to the immune system.

 Because side effects require a stronger immune system to detect and destroy the virus, younger people are more likely to have stronger side effects than adults. Maybe, because the T cell remembers the previous encounter with the spike protein. The body reacts to strong resistance to early destruction - this includes side-effects of cytokinesis.

The first dose teaches the immune system to detect the virus and start producing antibodies and T cells against it, and the second shot helps the covid 19 vaccines reach full 94% to 95% effectiveness.

Desai said the mRNA Covid-19 can cause even stronger side effects than flu shots because these vaccines strengthen the immune system. 

Bailey said their immune systems are already thought to be responding to the virus. Individual differences, such as stress levels and diet, can also affect side effects, Desai said.

 "They differ in the way they process vaccines," Bailey told LiveScience. However, clinical studies have shown that 90% to 95% of patients have a strong response to the vaccine.

 Rare side effects:

 Some serious side effects are associated with the vaccine, but they are incredibly rare.

 Very rare, for example, people develop anaphylaxis with the covid-19 vaccine - a life-threatening but easily treatable allergic reaction. For example, a January study from the Centers for Disease Control and Prevention's Journalia and Mortality Weekly Report found that anaphylaxis occurs in only 2.5 percent of every 1 million shots for the modern vaccine. (Pfizer shot also inspires rare cases of anaphylaxis)

 Other serious side effects may not be associated with some vaccines. Several European countries discontinued the AstraZeneca vaccine due to reports that blood clots rarely occurred. Bailey said the coronavirus itself had a clotting effect, so many experts suspected it was related to side effects.

 An EU investigation has determined that the covid 19 vaccine is safe for the general public and no specific link has been found to clots, although the EEU regulator has denied any connection.
