preservative – Track2Training

The Corona virus pandemic has swept over the planet and with it has brought about concepts like quarantine and social distancing which were earlier seen only in films. The lockdown that is widely being followed all over the world has not been the easiest time for people. With no provision to step out of the house, markets aren’t functioning and economies are crashing. A common man would wonder, ‘How am I supposed to help out, when I am locked inside my own house?’

Your miniscule contributions to the society, can massively assist the authorities and the paramedical staff in this time of need. A major step you can take during this quarantine period is to ensure that the waste produced in your home is minimized. In India alone, 21 million tonnes of food is wasted every year. This wasted food is often treated with plastic waste leading to emission of methane gas in a large quantity. While a life-threatening disease is upon the earth, one must not forget another crisis that is underway, that of global warming. Dealing with the COVID-19 gives us no excuse to forget caring for nature. The small roles we play at our house can make a huge impact outside.

How has Pandemic increased Waste Production?

The Corona Virus has forced the government to take some drastic measures. The shutting up of all non-essential shops across the country was the first of many shocks. People were advised to reduce their trips to the market in order to encourage social-distancing. Lots of families misunderstood this message and hoarded up on supplies to minimize their trips to the market. This uncalculated decision made by the people has led to the wastage of food on a large scale. The pandemic has led to the limitation of a few commodities and we cannot afford to waste even the slightest of food.

1. Buying Smart

The first step in moving towards a zero-waste lifestyle is to by only the amount of food you will require. Hoarding should be thoroughly discouraged as it is the main cause of waste production. The limited number of supplies means that the food you waste could have actually filled the stomach of a person in need.

2. Proper Storage

3. Use Items before they Expire

About 40% of the food produced in the country is thrown into the trash, uneaten. During the lockdown period, try and have a basic idea of the expiry dates all food items in your home. It is essential to make sure that no sort of canned or packaged food is kept win your house past its expiry date. Make sure that you have completely finished an item before going out to buy more. An interesting fact about packaged food is that some of it is safe to consume even after its ‘best before’ date. Check on the internet to find out if the can in your store room is still safe to consume. If not make sure it is disposed off correctly. Separate the food item from its packaging before throwing it away in two separate bins.

4. Utilize the Leftovers

The most important aspect of living a zero-waste life is to ensure that your leftovers are put to good use. Segregation into two different bins is an ideal way to dispose off leftover food. The only problem lying with this situation is that many garbage trucks and cleaners just pile all the garbage into one huge bag regardless of its recycling and ecological properties. The perfect way to deal with this problem would be to use the leftover food as compost.

People often avoid using compost as it is a long and slightly difficult process. The quarantine makes it a perfect time to finally do something good for the environment. Before creating compost make sure that you are doing it right. There are a lot of factors that need to be considered before generating a manure in your kitchen. Use proper tips and techniques from professionals for optimal results.

5. Mini Farming

Now that you have composed manure just from your wasted food, it is time to put that compost to good use. Indoor farming is not easy and it requires care and time but it is not necessary for you to own a huge balcony or a garden. You can grow vegetables even in the small terrace of your house. There are families around India who have become completely self-sufficient. Shilpa and Nitin, a couple based in the traffic heavy Bengaluru, grow more than 50 vegetables in their small balcony. Just one small pot for each type of vegetable is enough to sustain a family of four. The food they consume is from their own balcony and the waste produced in their home is used as manure to grow more vegetables. This ecological cycle can have a huge positive impact on the environment.

6. Eat Healthy

Perhaps the most underestimated way to reduce food wastage is to eat healthy. Junk food, has a much faster rate of decay when compared to fresh vegetables and fruits. Having a balanced and planned diet can help you minimize the amount of waste you generate. If you do not have the provision to create compost and farm in your balcony, you can start by eating healthy.

The COVID-19 pandemic has not been an easy time of us. Para medical staff and nurses are working overtime to ensure that we are safe the least we can do is reduce the burden on the planet. Correct utilization of leftovers and controlled generation of waste will make sure that the country has ample supply of food for the poor and needy. Play your part in the quarantine by changing to a zero-waste lifestyle.

ABSTRACT

Vaccines are a critical component of our anti-infectious disease strategy. In addition to pathogen-specific immunogens, vaccines often contain variety of preservatives,additives or adjuvants. The preservatives helps in preventing microbial growth,The Adjuvents such as aluminium salts help in enhancing antigen-specific immune responses and additives such as gelatin helps in stabilizing live viruses. It may also contain byproducts of substances used during its production.

The amount in which these ingredients are used is considered safe and each of them serves a specific intent but,some ingredients are considered harmful if present in high amount. Also ,these ingredients helps in certifying its effectiveness.

INTRODUCTION

Many of the components of vaccine are present in the human body. Many vaccine, for example, contain salts derived from sodium and potassium , which are vital for health. Although most people think it is an artificial chemical and found in minute amounts in the blood naturally.

These components are existing in trace levels, and no indication has been observed that these concentrations can lead to any damage. The limited percentage of individuals who seem to be hypersensitive to these components, even if it is existent only in low concentrations, is an exception . If you observe some vaccine components closely on the internet, you may notice that they are potentially hazardous, however maximum of them are often present in vaccines in quantities that are perfectly safe for human bodies. Even salt , which is required for regular biological function, is toxic in excess quantities.

INGREDIENTS IN VACCINE

As ,Each component of vaccine aids a specific purpose so the vaccine ingredients are used during production, help in providing resistance against a particular disease as well as keeping it safe and long lasting .

Antigens

Antigens are the constituents derived through structure of infection-causing organisms, which are regarded as ‘foreign’ by the body’s defenses and stimulates a defensive immune response to the vaccine.

In vaccines they are considered as active ingredients because they cause the body’s immune system to respond and develop defensive antibodies specific to that antigen. Antigens are either destroyed, weakened or artificially manufactured versions of the disease-causing organism or parts of the organism.

Individuals with weakened immune systems should not get live vaccinations because they may acquire the disease that the vaccine is designed to prevent.

Thimerosal

Thimerosal is a mercury-containing chemical compound. It is often used in the preservation of a variety of pharmaceutical drugs. It also protects against life-threatening contamination driven on by dangerous bacteria.It is used as a preservative in multi-dose vials of flu vaccinations, and it is also utilised in the production process of two related children vaccines.

When separate doses are taken from the multi-dose vial, the preservative thimerosal prevents contamination. Thimerosal is added to vials which contains multiple doses to prevent pathogens like bacteria and fungus from multiplying. When a syringe needle is inserted into a vial while preparing a vaccine for delivery, microbes and fungus can be introduced.

Contamination of a vaccine by microorganism may result in severe inflammatory response, acute illness, or death. these preservatives are added to some vaccines during the production process to inhibit microbial development.The kind of mercury present in certain types of fish is methylmercury. it can be harmful to humans at high amounts of exposure.it also includes ethylmercury, which is eliminated from the human body faster than methylmercury and so has a lesser risk of damage.

Aluminum salts

Even though we intake aluminum-containing foods and beverages on a daily basis, only a small quantity of aluminium enters the bloodstream during digestion; the remainder is excreted in the form of faeces. The kidneys processes and eliminates the majority of the aluminium in our bloodstream through urine.

In general, the use of aluminium adjuvants in vaccinations results in the requirement for less antigen or, in the case of certain vaccines, fewer doses.The use of aluminium salts in vaccines has a long and successful track of safety. Local responses and, less often, the formation of subcutaneous nodules at the injection site have been linked to aluminum-containing vaccine in some studies. This is especially true if the injection is administered too near the skin’s surface.

An evaluation of all known trials of tetanus, pertussis and diptheria vaccine containing aluminium salts found no evidence that aluminium salts in vaccines cause major or long-term adverse effects.

Sugars and Gelatin

Gelatin is derived from pigs and works as a stabiliser to protect living viruses from the effects of temperature. There have been a few reports of adverse response to vaccine containing gelatine in about one case out of every 20 lakh doses of vaccine.

Stabilisers inhibit chemical reactions in the vaccine as well as component separation or adhesion to the immunisation vial during transit and storage. Sugars like sucrose, amino acids like glycine, and amino acid salts, as well as partly hydrolyzed proteins, are all examples of stabilisers.

Egg protein

Frequently, vaccine producers utilise chicken eggs to develop an inactivated or live-attenuated vaccine, resulting in tiny quantities of egg protein in the vaccine.These vaccinations are refined after manufacturing to eliminate the culture components.

Even yet, certain remants of the culture may be left behind. People with severe allergies may be at danger as a result of this. In addition to most flu vaccines, egg protein can be found in the yellow fever vaccine. Even after taking the appropriate precautions, the danger of acquiring the flu or yellow fever nearly always overcomes the risk of obtaining the appropriate vaccinations in persons with severe allergies.

Formaldehyde

Formaldehyde is a naturally-occurring substance already present in the human body as a part of normal metabolism(Approx. 42.52 grams ) and is used by scientists for killing live microbes in inactivated vaccines . Its concentration in large amounts of can be extremely toxic. Formaldehyde breaks down into its basic elements quickly both in the environment or once consumed by the human body thus preventing its accumulation.Also, its amount present in vaccines is a small portion of per day value found in humans.It is used to detoxify or deactivate the live microbe or toxin used in some vaccines and most of It is removed during the process of purification. It is required for the synthesis of DNA.

CONCLUSION

Vaccine safety and efficacy are under research. Safety testing is done as soon as a new vaccine is under consideration, continues until it is approved, and is then monitored permanently after approval. Some vaccine contain preservatives to protect them against contamination by bacteria or fungi. The need for preservatives in vaccines emerged from a number of events in the early twentieth century in which patients acquired serious and most often lethal bacterial infections after receiving shots from multidose vials. In vaccines, each component has a distinct function. These components has undergone thorough research and proven to be safe for people. Safety testing occurs as soon as a new vaccines are under consideration, continues until it is approved, and is then monitored permanently after approval.
