New Methods Of Vaccine Delivery





The humankind has been riddled with maladies. Several medicines and vaccines came in the wake of advances in medicinal technology.  Many vaccinums are administered through injections. Syringes, needles and qualified medical personnel are required for giving injections. Research works point that injections cause both pain and stress. For averting pain and stress, researches are undertaken to develop new vaccine delivery methods. Read on to know.

Inhaled vaccines

Inhaled vaccines are among the first steps to minimize the use of needles.  For example, influenza can be controlled through an inhaled vaccine called Flu Mist. Measles is another disease for which the inhaled vaccinum are tested.  Similar to the inhaled vaccinum, another type is developed that can be delivered through lungs.

Needle-free patch

This technique heralded the concept of micro needle. In needle-free patch, an array of disc-shaped micro needle is put to use. A micro needle is made of sugar, and it dissolves within five minutes of penetration in the skin. Additionally, the needle-free patch technique maintains stability and efficacy of a live vaccine even in room temperature. The technique is the best alternative to the painful hypodermic needles.

Oral vaccines

Maladies such as cholera and polio are cured using oral vaccines. Research works are afoot for deriving oral vaccinum to protect against tuberculosis. As per several biological studies, orally developed vaccinums produce higher immune response than any of their injected DNA counterparts.

Advent of Transcutaneous Immunization

Researchers, vaccinum developers and biologists have undertaken several studies to understand the skin immune system. Such studies have led to the growth of Trans cutaneous Immunization (TCI). The TCI acts as an alternative route to offer higher immunization.

Breakthrough took place in the realm of vaccinum with the development of pneumococcal conjugate vaccine: it is meant for protecting young children and infants against pneumonia causing bacteria. Several vaccinum developers are cashing in on technological advancements to make the world a better place to live in.

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.

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.

Qualitative Vaccine Research is an effective way to ensure global health


A lot of medical institutes and laboratories are concentrating on vaccine research to help the nation in achieving vaccine transfer to prevent a number of deadlier diseases. Child immunization is one of the major areas where more focus is needed by the laboratories and the experienced medical research centres. It has been seen that globalimmunization is the matter of great concern when it comes to promoting global health on a larger scale. Besides this one cannot overlook the fact that with each passing day the requirement of initiating the idea of protecting children from contracting diseases such as diphtheria, smallpox, polio, cholera, typhoid and malaria through adopting  better-quality immunization methods.



Promoting vaccine research is one of the major challenges arising in health sector faced by the developing countries. For decades, experienced researchers and doctors have contributed to spread education and awareness on various vaccines like TB vaccine, hepatitis vaccine and HIV vaccine. However with passage of time it has become the struggle as lot of barriers are taking shape that certainly reduced the chances of getting the right kind of research measures. Problems are even arising due to the growing population in rural areas as it doesn’t seem to be realistic to enhance the quality of life in rural or backward areas of developing countries.

According to the recent research vaccine delivery done by various laboratories for the child immunization has become the prominent way to cope with the growing number of diseases. In addition, it adds to the growth of the society and can contribute to the growth of future generation in terms of facilitating healthy lives. Injecting the lives of children through immunizing them on time is indeed a best approach to initiate vaccination of high quality and efficiency. This can be done through involving in various global immunization campaigns and awareness campaigns. As we all know that children are most vulnerable because their immune systems are practically defenseless against the poisons in the vaccines. They have a lot going against them since their mothers do not pour on immunity through breast milk because they were vaccinated and no longer make certain antibodies. The fact is that the human immune system has been designed to protect us from even deadly illnesses but the key here is natural immunity. Vaccines, on the other hand, use synthetic chemicals to build artificial immunity. They work on the assumption that natural immunity is not good enough. While doctors are undertaking research on vaccines they make sure that the vaccine should pass various quality and sensitivity tests to ensure safe and effective vaccine delivery. This further includes that vaccines should pass the tests and it cannot be proven safe until they are given to human beings for the first time. But this would turn them into human 'guinea pigs' and it is not possible to predict what reactions they will have. This way the best researches can take place while keeping all the positives and negative effects in mind, it can lead to better deployment of factors that are responsible for the research.
