Astrazeneca Covid Vaccine Side Effects: A Comprehensive Overview

The Astrazeneca Covid vaccine has been widely used in the fight against the pandemic, but like any vaccine, it can cause side effects. In this article, we’ll explore the common and rare side effects associated with the Astrazeneca Covid vaccine, their management, and when to seek medical attention.

Vaccine Information: Astrazeneca Covid Vaccine Side Effects

The Astrazeneca Covid vaccine, also known as Vaxzevria, is a viral vector vaccine that protects against the SARS-CoV-2 virus, the virus that causes Covid-19.

It works by introducing a weakened version of a common cold virus (adenovirus) into the body. This virus has been modified to carry the genetic code for the SARS-CoV-2 spike protein. Once inside the body, the adenovirus delivers the genetic code to cells, which then produce the spike protein.

The immune system recognizes the spike protein as foreign and produces antibodies against it. These antibodies can then help protect the body from future infection with the SARS-CoV-2 virus.

Clinical Trials

The Astrazeneca Covid vaccine has been evaluated in several clinical trials. The results of these trials have shown that the vaccine is safe and effective in preventing Covid-19.

• In one trial, involving over 24,000 participants, the vaccine was found to be 76% effective in preventing symptomatic Covid-19.
• In another trial, involving over 12,000 participants, the vaccine was found to be 100% effective in preventing severe Covid-19.
