How Smallpox Faced a Complete Eradication?

Whenever a particular illness stops its circulation in a particular region, it is considered eliminated from that area. However, if the disease is eliminated from the entire face of the earth, then the phenomenon is called disease eradication.  To ensure both eradication and elimination of the disease, vaccine development is given the highest priority; the next slot in the vaccine researchers’ to-do list is secured by clean and quick vaccine delivery.

 

The first-ever disease eradication

Thus far, only one disease, smallpox, has been eradicated in 1980. The decades of initiatives taken by the World Health Organization (WHO) led World Health Assembly to declare smallpox disease as eradicated. Prior to its eradication, the long-in-the-tooth disease had claimed 35% lives of the infected people and left many hapless blind or scarred.

The eradication of smallpox was possible by coordinated efforts put in by the WHO and other health organizations. A well-structured surveillance was the key to eradicate smallpox from its root that had spread all over the world. As soon as a new case of smallpox was registered, the health officials were required to identify other such fresh cases in the same region and administer Ring Vaccination.  The final case of smallpox was reported in Somalia (1977).

Why smallpox was simpler to eradicate?

• Also referred to as variola, smallpox had an obtrusive presence as its patients quickly developed a peculiar form of rashes.
• Second, the time taken for the symptoms to appear was shorter than other diseases
• Third, such short duration had helped in quickly administering the vaccination and containing the disease
•  Final nail in the coffin was when the WHO took consistent efforts to introduce immunizationchart for variola and train the vaccinators. This step was taken to protect those who were not having lifelong immunity to the disease.

With the complete eradication of variola, many hopes were raised to eliminate other maladies such as malaria, polio, dracunculiasis, to mention but a few.

The Malaria Vaccine: Is it Still a Holy Grail?

For over millennia, Malaria has existed and destroyed several precious lives. With the path-breaking advances in medical science and technology, mankind has, on innumerable occasions, launched an attack to control this parasite. However, all those efforts were to no avail. Several clinical practices to test the candidate vaccine are still underway.

 What are the threats to the development of a malaria vaccine?

If figures are something to go by, mankind has an impressive gain by saving close to 1.1 million lives that almost succumbed to this fatal disease in a span ranging from 2001 to 2010. Such a feat was possible owing to the use of some advanced drugs and bed nets treated with insecticides. Nevertheless, the battle against Malaria has just escalated to a different level as a larger section of mankind is making no bones about showing resistance against the use of such powerful drugs and insecticides. 

What are the prospects of a developing a successful malaria vaccine?

A malaria vaccine is different from any other vaccine (such as that of polio, tetanus, etc.) due to the fact that it has to work with other interventions. First, due to the complexity of Plasmodium parasite’s genome, it has been a herculean task to derive a potent vaccine for averting the disease. Several renowned scientists are carrying out clinical trial (currently in phase three) for preventing the disease. But harboring the complexness of the parasite’s DNA, it is not wise to expect the probable vaccine to singlehandedly tackle the disease. As per the clinical trials taking place in 11 sites of Africa, the candidate vaccine (Mosquirix) is used with insecticide bed nets.

The complexity of vaccine development has always been critical for getting human race out of the clutches of some of the baneful diseases. Hence, only acclaimed name such as Hilleman Laboratories must be thought whenever a vaccine development task is at hand. Apart from vaccine development, the company prepares different types of immunization chart such as immunization schedule for kids. The company believes in the concept of global immunization and strives to achieve it; for any other detail go to – http://www.hillemanlabs.org/.

Ensuring Global Health through Vaccine Optimization for a Better Tomorrow

Development of vaccine is a strategic, slow and complex process that can be initiated by reliable and experienced labs. Over a time the system for developing, testing and regulating vaccine optimization has been modified to ensure improved performance. These days testing labs are adopting updated standards and regulatory policies to develop safe vaccines of high quality which are giving good results. The involvements of certain steps in vaccine delivery are significant to reduce the risks and improve the overall results. The process which has been followed to develop vaccines are being tested, and regulated in a very similar manner to other drugs. In general, vaccines are even more thoroughly tested than non-vaccine drugs because the number of human subjects in vaccine clinical trials is usually greater. In addition, post-development monitoring of vaccines is closely examined by the higher departments of disease control.

Safety is also an important phase in different types of the vaccine development process utilized by numerous labs all across the globe. Proven adverse events from the use of licensed vaccines are rare, and vaccines with known safety problems have been removed from the market. Successful vaccinations are highly effective and used globally in order to ensure critical health aspects with the removal of long medication processes. We have been heard that precautions is better than cure, vaccine is supporting this fact on the whole.

Immunization chart is the best and only way that parents can adopt to reduce the chances of skipping any of the vaccine of their child in the initial years of the birth. This chart includes age, vaccination name and how it is given, that facilitates you to track and not to skip any vaccination of your child and brought consistency.

Apart all the benefits of developing a vaccine, it has some major or minor obstacles that can be broadly classified as economic obstacles, technical obstacles and cultural obstacles. Successful vaccines have the scope of introducing and supporting new programs to deliberately providing positive consequences. Vaccines have helped eradicate the worst infectious diseases in the developed world. Research and development must continue the progress of the past and address those diseases that have eluded the development of effective vaccines and the diseases that continue to devastate regions where vaccines have been unavailable. Research is also needed to improve existing vaccines.

There are certain misconceptions related to vaccination, that it should fulfill a net cost-savings is a major obstacle to vaccine development. As a matter of fact costing of vaccination is one of major obstacle in India or outside. To resolve this with consistent approach governments and individuals should be prepared to pay a certain cost to improve health and avoid suffering. Recently studies shows that vaccine development is hampered by the current pricing structure in the U.S., which for some diseases fails to allow adequate compensation for the companies that develop vaccines in the early years following license. Paying prices for vaccines that take into account their health and lifesaving attributes, would encourage more research, more innovation, and better, safer vaccines.
