There is a massive shortage of oxygen cylinders in hospitals, people are not able to find hospital beds for their family members, and this is leading to numerous deaths. Even after the death of their respective relatives, people are not able to find burial or crematorium grounds for their known ones. The situation is very haunting and daunting.

    But the good news is that every government regime came out with a COVID-19 vaccine that could help people stay safe. The Indian government announced the second phase of the vaccination drive. This vaccination drive will be made available for everybody who is above 18 years of age. The registration process for the vaccine drive has also started on government-led portals. Till now, India has two vaccines available: Covaxin and Covishield.

    If you are going to a vaccine drive and you are unsure about which vaccine you should probably ask for, then this blog is for you where we will be describing everything about Covaxin Vs Covishield difference, side effects, efficiency, and efficacy rate. This article is going to help you and your family members in knowing which is the best vaccine drive for you. So, don’t live in a dilemma or web of lies and choose the best vaccine yourself.

    Covaxin Vs Covishield Difference: What Do We Know About Them

    The very first part to understand in this article of Covaxin vs Covishield difference is whatever we know about both of them. Check out the information available for both of the vaccine counterparts:


    Covaxin is developed by Bharat Biotech. Bharat Biotech is a 24 years old vaccine manufacturer, having a portfolio of 16 vaccines. This huge organization exports vaccines to 123 countries, making it a reliable option for vaccine manufacturers.


    The list of Covaxin Vs Covishield differences is incomplete without introducing our second and last counterpart; Covishield. Covishield is developed by Oxford-AstraZeneca. Oxford-Astra-Zeneca is the biggest vaccine manufacturer in the world. Oxford-Astra-Zeneca claims that it produces over 60 million doses a month.

    Covaxin Vs Covishield Difference: How They Work

    Moving ahead to the next part of the Covaxin vs Covishield difference. The next part of the article is how both of these wonder vaccines work.

    • Covaxin Working

    Covaxin is an inactivated vaccine prepared on a tried-and-tested virus network. The entire-virus Vero cell-derived vaccine is being made. They contain inactivated viruses, which cannot infect a person but still teach the immune system to develop an active virus defense mechanism.

    For decades, these traditional vaccines have been used. Vaccines are often made using the same technology for certain other diseases.

    These conditions are:

      • Seasonal flu
      • Pertussis
      • Rabies
      • Polio
      • Japanese encephalitis
    • Covishield Working

    Covishield was generated using an entirely different viral vector platform.

    An adenovirus chimpanzee – ChAdOx1 – has been amended to transport COVID-19 spike protein into human cells. Well, the cold virus can’t infect the recipient but can teach the immune system a way to prevent such viruses.

    The accurate technology has been used to develop virus vaccines such as Ebola. Covishield was generated using an entirely different viral vector platform. When a patient is injecting the vaccine, antibodies are initiated in the immune system and any virus is attacked.

    Covaxin Vs Covishield Difference: Storage Condition

    The next point to understand in Covaxin vs Covishield difference is the storage condition in which they are stored. The household refrigerator temperature of Covishield and Covaxin can be kept at 2-8 degrees Cels. The two vaccines are therefore best suited to Indian conditions, as most vaccines are stored at the same temperature.

    The movement and handling of both vaccines are also simplified. Covishield can be securely processed and delivered in current health facilities such as doctors’ surgeries at 2C to 8C temperatures. Covaxin can also be securely processed and transported at 2C to 8C temperatures.

    Covaxin Vs Covishield Efficiency

    The efficiency of any vaccine is called efficacy. This point was important for understanding the Covaxin vs Covishield efficiency. The Covaxin vs Covishield efficacy rates is almost the same.

    • Covishield Efficacy

    International Oxford-AstraZeneca clinical trials have shown that efficacy is 90 percent when people receive a half and then a complete dose. But the half-dose, the full-dose concept was not sufficiently clear evidence. Unpublished results indicate. However, that the overall efficacy of the JAB increased by leaving a longer distance between the first and second dose, which is 70 percent effective in the first dose in a subgroup given the vaccine.

    Covishield is “highly reliable,” and is supported by Phase III testing data from Brazil and the United Kingdoms, said the Serum Institute (SII), the Indian vaccine manufacturer. Clinical studies are a three-phased procedure to assess whether the vaccine produces healthy immune responses and whether unacceptable side effects.

    All India Drug Action Network, a group of patients’ rights, has indicated its approval was hurried since a “bridging analysis” on the Indian vaccine was not carried out by the producer.

    • Covaxin Efficacy

    The next point to clarify in the Covaxin vs Covishield efficacy rate is by going through the efficacy rate shown by Covaxin in its clinical trials.

    The Covaxin Covid-19 vaccine in India was approved without any Phase III data for emergency use back in January. These data are now released, but the vaccine is in controversy in the meantime. Bharat Biotech from India finished with interim Phase III information for its Covid-19 shot, with a 78% efficacy vaccine to prevent mild, moderate, and severe coronavirus infections and perform well to prevent most variations.

    Due to the recent surge of Indian vaccinations in 127 cases, the vaccine efficacy of 78% has been estimated to be point-only (95% of CI: 61-88) with mild, moderate, and extreme vaccinations.

    Covaxin Vs Covishield Side Effects

    Both Covaxin and Covishield show minimum to mild side effects due to the introduction of a new component in the body. Now we will be discussing Covaxin vs Covishield side effects:

    • Covaxin Side Effects

    Covaxin side effects are minimum and they occur immediately after taking the first shot of the vaccine. Covaxin side effects fade away before taking the second shot. After taking the second shot, covaxin side effects may show up once again. Covaxin side effects are as follows:
