This article provides information about Covaxin, a COVID-19 vaccine developed by Bharat Biotech in collaboration with the Indian Council of Medical Research and the National Institute of Virology and covers the efficacy and safety of the vaccine, who can receive it, how it is administered, its effectiveness against variants of the virus, and how to access it. The FAQ section answers common questions about Covaxin.
As the world grapples with the COVID-19 pandemic Covaxin, several vaccines have been developed and authorized for emergency use to prevent the spread of the virus. Covaxin is one such vaccine that has been developed in India to fight against COVID-19. In this article, we’ll take a closer look at what Covaxin is, how it works, and its effectiveness.
What is Covaxin?
Covaxin is a COVID-19 vaccine developed by Bharat Biotech, an Indian biotechnology company based in Hyderabad. It is an inactivated vaccine, which means that it is made from the virus particles that have been killed or inactivated, so they cannot cause disease. The vaccine is administered in two doses, given 28 days apart.
How does Covaxin work?
Covaxin works by stimulating the immune system to produce antibodies against the SARS-CoV-2 virus, which causes COVID-19. When the vaccine is injected into the body, the inactivated virus particles in Covaxin trigger the production of antibodies and T cells that can recognize and neutralize the virus if the person is exposed to it in the future.
Is Covaxin effective?
Covaxin has been shown to be effective in preventing COVID-19 in clinical trials. In phase 3 trials, which involved over 25,000 participants, Covaxin demonstrated an overall efficacy rate of 78% against symptomatic COVID-19 and 100% efficacy against severe COVID-19. It has also been found to be effective against the new variants of the virus, including the Delta variant.
Covaxin has been authorized for emergency use in India, and it is currently being used in the country’s vaccination drive. The vaccine has also been authorized for use in several other countries, including Iran, Mauritius, Mexico, and Zimbabwe.
What are the side effects of Covaxin?
Like all vaccines, Covaxin can cause side effects, but they are usually mild and temporary. The most common side effects reported in clinical trials include pain at the injection site, headache, fatigue, fever, and body aches. These side effects typically resolve on their own within a few days.
It’s important to note that the benefits of getting vaccinated against COVID-19 outweigh the risks of side effects, and the vaccine has been shown to be safe and effective in preventing the spread of the virus.
Common side effects of Covaxin
The following are some of the most common side effects reported after receiving Covaxin:
- Pain and swelling at the injection site
- Fatigue
- Headache
- Muscle aches and pain
- Fever and chills
These side effects are usually mild to moderate in severity and resolve on their own within a few days after vaccination. They are a sign that the body is mounting an immune response to the vaccine and are not a cause for concern.
Uncommon side effects of Covaxin
While rare, some individuals may experience more severe side effects after receiving Covaxin. These side effects include:
- Allergic reactions: Some individuals may experience an allergic reaction to one or more components of the vaccine. Symptoms of an allergic reaction may include hives, swelling of the face and throat, difficulty breathing, and rapid heartbeat. It is important to seek immediate medical attention if you experience any of these symptoms after receiving the vaccine.
- Blood clotting disorders: There have been reports of blood clotting disorders, such as cerebral venous sinus thrombosis (CVST), in individuals who received Covaxin. However, these cases are rare, and the benefits of vaccination outweigh the risks for the vast majority of people.
- Guillain-Barré Syndrome (GBS): There have been reports of GBS in a small number of individuals who received Covaxin. GBS is a rare disorder in which the immune system attacks the nerves and can cause muscle weakness and paralysis. Again, the benefits of vaccination outweigh the risks for most people.
Overall, this is a safe and effective vaccine for preventing COVID-19 infections. While some individuals may experience side effects after vaccination, these are generally mild and resolve on their own within a few days. If you are concerned about the side effects of it, speak with your healthcare provider or a trusted medical professional to learn more about the benefits and risks of the vaccine.
Development and Approval Process
Covaxin was developed by Bharat Biotech in collaboration with the Indian Council of Medical Research (ICMR) and the National Institute of Virology (NIV). The vaccine underwent clinical trials in India and received emergency use authorization from the Drug Controller General of India in January 2021.
Since then, the vaccine has been authorized for use in several other countries, including Iran, Mauritius, Mexico, and Zimbabwe. It is also undergoing clinical trials in several other countries.
Efficacy Against Variants
Covaxin has been found to be effective against several variants of the SARS-CoV-2 virus, including the Delta variant, which is highly transmissible and has caused a surge in cases in many parts of the world. Studies have shown that the vaccine produces neutralizing antibodies against the Delta variant, indicating that it can provide protection against the variant.
Importance of Vaccination
Getting vaccinated is an important way to protect ourselves and others from COVID-19. Vaccines like Covaxin help to reduce the spread of the virus, lower the risk of severe illness, and ultimately save lives. It’s important to continue to follow public health guidelines even after getting vaccinated, such as wearing masks and practicing physical distancing, until the pandemic is under control.
Manufacturing and Distribution
Bharat Biotech has ramped up production of Covaxin to meet the high demand for COVID-19 vaccines in India and around the world. The company has also partnered with other manufacturers to produce the vaccine, with the aim of reaching a production capacity of 700 million doses per year.
The Indian government has also played a key role in the distribution of Covaxin, with the vaccine being made available to eligible individuals through a phased rollout. The government has also donated doses of the vaccine to other countries as part of its efforts to support the global fight against the pandemic.
Clinical Trials and Effectiveness
Covaxin underwent clinical trials in India, involving over 25,000 participants across several states. The trials showed that the vaccine was safe and produced an immune response against the SARS-CoV-2 virus.
Since its emergency use authorization, studies have shown that Covaxin has an overall effectiveness of around 81% in preventing symptomatic COVID-19 infections. The vaccine has also been found to be effective against several variants of the virus, including the Delta variant.
Challenges and Controversies
Like other COVID-19 vaccines, Covaxin has faced some challenges and controversies. In particular, concerns have been raised over the lack of data on the vaccine’s efficacy and safety in certain populations, such as pregnant women and children.
There have also been concerns about the approval process for Covaxin, with some experts questioning whether the vaccine was authorized for emergency use before sufficient data was available to support its safety and effectiveness.
