Breakthrough in Hepatitis B Disease!
It has been estimated by WHO that around Six Lac people die every year due to dangerous form of Hepatitis which is known as Hepatitis B. With focus on this deadly disease, researcher at the University of Coimbra had successfully developed oral vaccine for Hepatitis B and is more stable and efficient than injectable vaccine which is available in market.
At the Centre for Neuroscience (CNC), a team of around five scientists had contributed in developing this useful vaccine. Presently these vaccines are test in vivo (that is in animals like mice) and seems to be successful and more promising than injectable vaccine. One more advantage of this is that this does not need only technical staff to administer it. In spite of their effective properties, many vaccines are of no use at the time when it reaches the end user. This is because; they are not stable in high temperature conditions and needs intensive care during cold chain transfer. This is not the case with oral hepatitis B vaccine which has been developed and therefore will be effectively used in many countries which does not have effective cold chain conditions. This will reach to end user with same potential and stability.

The administration of oral vaccine will also have other benefits like may be used for patients already infected with disease. The virus will be fought at the point of administration and thus will also prevent it from being release in bloodstream. This study had taken a decade time but will be effective for thousands of years to come. During the research many nanotechnologist were involved which developed antigens using nanotechnology such that these antigens holds the antigenic properties while not affecting the health by not infecting the host. That is they successfully created antigen with antigenic properties and removing pathogenic properties which exists in Hepatitis B virus.This helped in vaccine development and showed a new way to the field of vaccination .
Thus this research is also aligned with the objectives of the WHO and that is to focus on the development of vaccines which are more stable, effective, cheaper and easier to administer in the body.
