What Do You Know About Neurological Complications After the Sars-CoV-2 Infection and Covid-19 Vaccination?

The Covid-19 virus has rapidly spread worldwide, and many variants have already been identified. The Covid-19 vaccines have proven their efficiency after researchers, pharmaceutical companies, and health experts conducted many clinical trials, gathered data from health institutions and vaccination centers around the globe. The CDC has been releasing updates on Covid-19 and available vaccines on the official website, including information about mixing vaccine doses and guidelines for booster shots. 

Astra Zeneca Vaccine was tested on more than 11,000 participants

Before being released and issued emergency authorization, The Oxford AstraZeneca Covid-19 vaccine (ChAdOx1 nCoV-19) has been tested on more than 11,000 volunteers from the U.K, South Africa, and Brazil. 

The Pfizer BioNTech (BNT162b2) Covid vaccine has been tested on more than 43,000 volunteers, and in August 2021, the FDA issued it a full authorization. 

Rare vaccination side-effects are still possible

Despite the fact that vaccines undergo rigorous trials and manufacturing procedures, and the vaccination benefits outweigh the risks of possible side effects, there were rare adverse events associated with them. According to an article published in Medical News Today, a rare adverse event reported after the Covid-19 vaccination was the risk of developing neurological complications.

However, the Covid-19 virus attacks not only the respiratory system but also the nervous system. Data collected worldwide indicates that the virus triggers more side effects, including neurological complications, than vaccination. 

Neurological complications are more likely to happen after the SARS-CoV-2 infection

A recent study published in Nature Medicine has released statistics and data of neurological complications after a first dose of Covid-19 vaccines and after the SARS-CoV-2 infection. Researchers analyzed over 32 million health care records of people who got vaccinated in England, including 2 million people who tested positive for the virus prior to vaccination.

 The results of the study pinpointed that there is a greater risk of developing neurological complications after going through the viral infection than after being vaccinated against it. Therefore, for the moment, vaccination is the best preventive weapon against the virus.
