Covishield Vs Cowaxin - which one you should take?

Jenson 4 weeks ago

Have you got your first covid vaccine dose yet? With 20% of the population getting their first dose of vaccine in India, which includes people over the age of 18, we still have a lot of speculations following the efficacy and side effects of the vaccine, and the availability of 3 different vaccines i.e. Covishield, Cowaxin, and SputnikV makes it even more confusing for the people. There is no doubt that vaccination can help save millions in this fight against the coronavirus, so we should keep ourselves well informed and prepared to take life-saving shots. The third phase of the Mega Vaccination Campaign in India is at its peak and there are so many people who have numerous questions and doubts about how, when, and which vaccine to take. In this blog, we will be answering all the questions related to the differences and characteristics of the two most popular vaccines in India, Covishield and Cowaxin.

With the COVID-19 vaccination drive that initiates with the online registration of each citizen, the government is now allowing people to choose the different vaccines depending on the availability and many people are still unaware of how the two vaccines are different from each other. Thousands of research and experience from the first two drives clearly suggest that both the vaccines - Covishield and Cowaxin - being inoculated in India are safe and effective against harmful health issues of the covid-19 virus. There are some underlying differences between them that have been discussed below:

Development and Origin:

Covishield-  The Oxford-AstraZeneca vaccine is being manufactured locally by the Serum Institute of India (SII). The vaccine is developed from a weakened version of a common cold virus (known as an adenovirus) from chimpanzees and has been modified to help our immune system learn to counter coronavirus. The modification allows the Adreno virus to look more like coronavirus but does not cause any illness in humans. 

Covaxin- India's indigenous COVID-19 vaccine has been developed by Hyderabad-based Bharat Biotech International Ltd in association with the Indian Council of Medical Research (ICMR) and the National Institute of Virology (NIV). The vaccine is developed using Whole-Virion Inactivated Vero Cell, which does not replicate and is therefore unlikely to revert and cause pathological effects. 


Both the vaccines, Covishield and Cowaxin, have been granted approval for emergency restricted use in India by the Drugs Controller General of India (DGCI), which can potentially prevent coronavirus infection in people aged 18 years and above.


AstraZeneca’s COVID-19 vaccine has been granted Emergency Use Listing (EUL) by the World Health Organization (WHO) for active immunization to prevent COVID-19 in individuals above 18 years of age. Particularly Covishield by the Serum Institute got WHO’s approvals for the global rollout of vaccines in February 2021 and is working with the COVAX Facility to begin supplying the Covid-19 vaccine around the world. 


Cowaxin is yet to get approved by The Emergency Use Listing (EUL) regulated by global health bodies and WHO to seek emergency use of the vaccine globally. The clinical trials for Cowaxin in other countries will commence soon and vaccine supplies will be shared between governments of Myanmar, Sri Lanka, Mongolia, Oman, Philippines, Bahrain, Maldives, and Mauritius. It's just a matter of time before Cowaxin gets globally recognized for its effectiveness against coronavirus and relaxation for traveling abroad. 

The below table compares other characteristics of both the vaccine:



Efficacy - overall vaccine efficacy was found to be 70%.-100%.

Efficacy - Kovid injection, the effect is 70% -90%.

Side effects-

-Pain in the arm on which the injection has been done

-numbness in the arm

-Swelling at the throat

-Mild fever, headache, body ache

Side effects-

-dizziness and weakness


Note: These side effects are just assumptions with few to none being noticed in the majority of the people who have taken these vaccines. Also, none have been noticed for a prolonged period of time and usually last 2 - 5 days.

However, wearing personal protective equipment (PPE) after vaccination is still just as important as ever and you should always stock your personal protective gear at home and workplace to protect yourself and your loved ones.
