The Covid-19 pandemic has affected millions of people worldwide and led to the loss of countless lives. Vaccination has been the key strategy in combating the virus. In India, Bharat Biotech, a leading biotechnology company, has developed an indigenous Covid-19 vaccine, Covaxin. The vaccine has been administered to millions of people in India and has shown promising results.
What is Covaxin?
Covaxin is an inactivated Covid-19 vaccine developed by Bharat Biotech in collaboration with the Indian Council of Medical Research (ICMR) and the National Institute of Virology (NIV). The vaccine is made using a virus strain that has been inactivated, ensuring that it cannot cause the disease. The inactivated virus is then used to stimulate the immune system to produce antibodies against the virus.
How does Covaxin work?
Covaxin works by stimulating the immune system to produce antibodies against the Covid-19 virus. The vaccine is administered in two doses, 28 days apart. The inactivated virus used in the vaccine stimulates the immune system to recognize and attack the virus. Once the immune system is primed, it can produce antibodies against the virus, protecting the body from infection.
Efficacy of Covaxin
Several studies have been conducted to determine the efficacy of Covaxin. According to the interim results of a phase 3 trial, the vaccine has an efficacy of 78% against symptomatic Covid-19 and 100% efficacy against severe disease. The vaccine has also shown efficacy against new variants of the virus, including the Delta variant. The data from these studies has been submitted to regulatory authorities for approval.
Significance of Covaxin in India's fight against Covid-19
Covaxin has played a significant role in India's fight against Covid-19. The vaccine was granted emergency use authorization in January 2021 and has been administered to millions of people in India. The government has also ramped up production of the vaccine, ensuring that it is widely available across the country. Covaxin has helped India in achieving a high vaccination coverage, which has been critical in reducing the number of cases and deaths due to Covid-19.
Covaxin controversy
Covaxin has also faced criticism and controversy. Some experts have raised concerns about the vaccine's efficacy and safety, citing the lack of data from phase 3 trials. Additionally, the vaccine was granted emergency use authorization before the completion of phase 3 trials, leading to concerns about the vaccine's safety. However, the government and Bharat Biotech have maintained that the vaccine is safe and effective.
Future of Covaxin
Covaxin is set to play a crucial role in India's vaccination drive in the future. The government has approved the use of Covaxin for children aged 2-18 years, and the vaccine is also being tested for use as a booster dose. Bharat Biotech is also working on a nasal vaccine for Covid-19, which could be a game-changer in the fight against the pandemic.
