Despite conveying the message that the covid vaccines are generating a strong immune response, the possible adverse effects have made individuals wary of being injected.

“The mRNA-based vaccines of Pfizer and Moderna have received the most attention with regard to the side effects of vaccination,” according to a study published in the journal Science Immunology.

The article continues: “As with other vaccines, these effects can on rare occasion be the result of delayed-onset, local allergic reactions.”

It cites a “combination of fever, headache, myalgia and general malaise” as the main symptoms reported, which typically follow the second dose of the vaccines.

“These symptoms can be troubling and have been the subject of comment in the press and in top scientific journals.”

However, as stated in the journal research, the “actual cause of the side effects has received almost no attention”.

According to the report, “most of the symptoms can likely be attributed simply to exuberant production of a cytokine that plays a vital role in potentiating early stages of the immune response”.

Cytokines are small proteins that aid in the mobilisation and coordination of an efficient immune response.

Some of the vaccine’s side effects may be unpleasant, but current data suggests that vaccines are decreasing the connection between infection and hospitalisation.

In comparison to the dangers presented by COVID-19, the adverse effects of vaccination are therefore minimal.

Vaccines provide effective protection, but it takes time for that protection to develop.

“People must take all the required doses of a vaccine to build full immunity,” explains the World Health Organization (WHO).

WHO continues: “For two-dose vaccines, vaccines only give partial protection after the first dose, and the second dose increases that protection.

“It takes time before protection reaches its maximum level a few weeks after the second dose.

“For a one-dose vaccine, people will have built maximum immunity against COVID-19 a few weeks after getting vaccinated.”
