Read about a new study from researchers that found a new technique to preserve vaccines from degrading in suboptimal temperatures.
Scientists have now, however, found a way to prevent the degradation of vaccines due to warmer temperature: encasing the protein molecules in a silica shell. This allows the structure of the vaccine to remain intact even when heated to 100 degrees celsius, or stored at room temperature for up to three years.
This technique of tailoring a silica coat to fit the vaccine, called ensilication, was developed with a University of Bath research team in collaboration with the University of Newcastle. While the technique proved its effectiveness in the labFor their study, the researchers sent both ensilicated and regular samples of the tetanus vaccine from Bath to Newcastle, a journey of over 300 miles, which takes up to two days by mail.
“This is really exciting data because it shows us that ensilication preserves not just the structure of the vaccine proteins but also the function – the immunogenicity,”
