Vaccine failure is always linked with laboratory techniques failure but most of the vaccines failure happen outside the labs that is during transportation. A vaccine that is perfectly manufactured can become useless if it is exposed to the wrong temperature for even a few hours. Globally, a large number of vaccine doses are wasted each year because cold chain systems break down, especially in regions with unreliable electricity and transport making it a global issue.
The COVID-19 pandemic made this problem impossible to ignore, as temperature-sensitive vaccines struggled to reach remote areas on time. Today, researchers are focusing on heat-stable formulations and better packaging rather than new vaccine targets which is the need of the hour because it is better to focus on dispensing rather than just formulating. These changes may not look revolutionary, but they could protect more lives than discovering another vaccine because we will be able to dispense it to diverse population. Sometimes, the real innovation lies in delivery, not discovery.
What are some areas to focus on while improving vaccines and making more practical to use ?
