Priming Of The Immune System As Vaccination in India

Vaccination is the method to prevent infectious diseases in the body. Due to widespread of immunity and vaccination in India and world, worldwide eradication of smallpox has been made possible, along with restriction of diseases (polio, measles and tetanus) from much of the world.

According to World Health Organization (WHO), licensed vaccines are currently available to prevent or contribute to the prevention and control of twenty-five preventable infections.

The vaccination was renamed as immunization because it was derived from a virus affecting cows (Latin: vacca–cow). Though in common speech, vaccination and immunization have a similar meaning. The only thing distinguishes them is inoculation, which uses unweakened live pathogens, although in common usage either can refer to an immunization.

The process of artificial induction of immunity through an effort to protect against infectious disease, involves ‘priming’ of the immune system with an ‘immunogen’. The stimulation of immune responses with an infectious agent is known as immunization.

Smallpox was most probably the first disease on which people tried inoculation and was the first disease for which a vaccine was produced. It was a contagious and deadly disease. The vaccine for small pox was discovered by the British physician Edward Jenner. He was the first one to publish evidence that his principles were effective and to provide advice on its production, though at least six people had used the same principles. Louis Pasteur had further taken the concept through his work in microbiology.

The latest recommended chart for vaccination in India to all the children includes 13 vaccines, with names BCG, HepB, Poliovirus, DTP, Hib, PCV, RV, Typhoid, MMR, Varicella, HepA, Tdap, HPV.

Vaccines Management and Supply process in India

For the maintenance of vaccine logistics and supply chain, eVIN has created a system which ensures that the stocks are available in every district, on time, without any compromise in the quality. The efforts done in monitoring and maintaining records of the vaccines, show growth in vaccines deliveries.

How To Store and Preserve Vaccines?

In order to store and monitor vaccines properly, the department of disease control and prevention always issues few tips or guidelines. The state vaccine for kids programs need that guidelines practice this message as a minimum. They can also choose to require strict criteria for their programs. These guidelines are made to keep vaccines safely. Even in vaccine logistics and supply chain, they are not supposed to open to temperatures at which they may lose their impact and effects.

Vaccines need to be preserved even during vaccine logistics and supply chain. If you notice the manufacturers of the vaccines, they also give proper guidelines to store the vaccines. The manufacturers provide the product related content that includes at what temperature the vaccines should be kept, if needed then how to use a diluent to reconstitute a vaccine and when to drop the vaccines.

The disease control and prevention vaccine storage and handling toolkit’s centers offer ideas that are good for workplaces, but offer as minimum requirements for vaccine for kids providers. The basic points are

1) Exercising a temperature buffered probe rather than counting ambient air temperatures.
2) Practicing a digital data logger with a detachable probe that continuously records and stores temperature information at regular programmable intervals.
3) Having a stand-alone refrigerator and stand-alone freezer units good for vaccine storage rather than combination (refrigerator + freezer) or other units not made for storing vaccines.
4) Stop using dorm-style or bar-style refrigerator/freezers for vaccines’ storage, even temporary.
5) Timely review of expiration dates of vaccines and changing of vaccine stock.

Don’t let your vaccines open to temperatures at which they may lose their potency in the times of vaccine logistics and supply chain. In the immunization training book, you will also find the tips for storing the vaccines that include

1) the refrigerator temperature should be measured between 2°C and 8°C.
2) The freezer temperature should be measured -15°C or lower.
3) Vaccines which are prepared to be stored in the refrigerator should never be frozen.
4) The refrigerator and freezer’s temperatures should be checked at least twice each day. The maximum and minimum temperatures reached each day should also be checked on the temperature log.
