Indian researchers, in collaboration with Bharat Biotech and Washington University in St. Louis, have developed an innovative nasal vaccine for COVID-19 called iNCOVACC. This groundbreaking vaccine, which is administered through the nose, has received emergency use approval in India for both primary vaccination and as a booster. Unlike traditional injectable vaccines, the nasal vaccine aims to block the virus right at its entry point in the nasal passages and upper respiratory tract, potentially preventing infection and breaking the transmission cycle.

The nasal vaccine’s ability to trigger a strong immune response directly where the virus enters the body is a significant advantage. This could not only prevent severe disease but also reduce the spread of the virus, which is a crucial aspect that injectable vaccines have struggled with. Moreover, the nasal vaccine is easier to administer, as it doesn’t require needles, making it more accessible and less intimidating, especially for those who fear injections.

This new approach could revolutionize the global fight against COVID-19 and other respiratory illnesses. By focusing on mucosal immunity, the vaccine may be more effective in stopping the virus from spreading, thus playing a vital role in controlling the pandemic and preparing for future outbreaks. Additionally, the vaccine is designed to be cost-effective and easy to store, making it particularly suitable for use in low- and middle-income countries.
