Yearly flu vaccination is the best tool currently available to protect against influenza (flu).

While how well the flu vaccine works can vary, the Centers for Disease Control and Prevention (CDC) recommends a yearly flu vaccination as the first and most important step in protecting against flu and its potentially serious complications. Millions of people have safely received flu vaccines for decades. Flu vaccination can reduce flu illnesses, doctors' visits, and missed work and school due to flu, as well as prevent flu-related hospitalizations.

A flu vaccination does not guarantee protection against the flu. Some people who get vaccinated might still get sick. However, people who get a flu vaccine are less likely to get sick with flu or hospitalized from flu than someone who does not get vaccinated.

Why do I need to get vaccinated every year?

New flu vaccines are released every year to keep up with rapidly adapting flu viruses. Because flu viruses evolve so quickly, last year's vaccine may not protect you from this year's viruses.

After vaccination, your immune system produces antibodies that will protect you from the vaccine viruses. In general, though, antibody levels start to decline over time   another reason to get a flu shot every year.

Flu vaccines bring down the risks of suffering from flu. However, its effectiveness is based on different factors.

Age: Usually, the flu vaccine happens to work the best for healthy adults. However, these vaccines cannot work as well with children, especially infants (below the age of 2-3 years). Nevertheless, the efficacy improves with age. Since older people are more prone to contracting the flu virus, it is essential that they get themselves vaccinated. Even if the vaccine is not able to ward off the flu entirely, it can still help reduce the risks to some extent.

General Health: Vaccine spurs immunity into action. It helps your body in identifying and fighting the virus. The efficacy of the flu vaccine solely depends on the capability of your body s immunity system and how well it responds to the virus. Chronic illnesses weaken your body s defense mechanism and with a poor immunity system, the vaccine may not work properly.

The time of the vaccination: For optimal protection, it is advised to go for the vaccination every year right before the  flu  season starts. This is because after the flu season gets done with, old vaccines may not work as effectively.

The flu vaccine needs to be updated every season to guard you against the kind of flu dominant in that particular year. Getting yourself vaccinated is also not a guaranteed foolproof protection, however, it does render partial immunity and helps reduce the severity of the symptoms. However, it should be noted that flu vaccine cannot shield one from cold viruses.

Flu Vaccine Effectiveness: How Well Does It Work?

Seasonal changes can be very exciting for most people. Each season brings with it a new set of colours and nature takes a new turn. However, for people with seasonal allergies, a seasonal change also comes with a set of allergies. From skin rashes to wheezing to breathing difficulties, the list of symptoms can be quite long. Asthma is the most common problem, and the attacks can be quite bothersome with wheezing attacks and breathing troubles.

With advancements in the field of medicine, there is a lot of relief for asthma patients. A little understanding on how asthma attacks happen will help in understanding how to control it. Asthma is an allergic reaction caused by narrowing of the airway with thick mucus, which makes breathing difficult. During an attack, the person can have a dry cough, face shortness of breath and wheezing.

Asthma is often triggered or worsened by some factors, and being aware of these can help prevent or manage an attack:

Common allergens like pollen, mites, ticks, furs of animals, bird feathers, specific foods (peanuts, milk products, eggs, etc.) and mold spores appear during change of season.
Environmental chemicals like cigarette smoke, car fumes, dust, etc., can also trigger an attack.
Attacks of cold or flu can lead to an asthma attack.
Workout during cold weather can be problematic, but exercise can also help control asthma attacks. Lung function improves sufficiently, but an exercise regime should be drawn up for the patient based on his condition.
Stressful emotions like anger and anxiety can also lead to an attack or make it worse.
Some medications like aspirin, beta blockers, glaucoma drops can aggravate attacks of asthma.
Once you know the triggers, here are some common measures that can help prevent and relieve the wheezing.

The preventers reduce the inflammation in the airway tube and the swelling. While they do not provide immediate relief during an attack, using these in the long term helps avoid attacks. These are low-dose inhaled corticosteroids such as beclomethasone, fluticasone, and budesonide. Doctors would advise their usage even when there are no symptoms, as asthma attacks can be triggered when they are not taking these medications for a while. Newer drugs include leukotriene antagonists like montelukast and zafirlukast. Relievers are used for symptom relief and include Salbutamol (short acting) and Salmeterol/Formoterol (long acting). Peak flow meter may be useful in acute attacks, wherein the peak flow rates can be reduced.
A good strategy is to use preventers regularly and rely on relievers during an attack. The first one helps build resistance and so reduces the incidence of attacks. Reach out to a doctor if a severe attack ensues (lasts more than 3 hours).


Tips to Control Allergy Driven Wheezing this Season

One thing that a weather change brings about is lung infections - most commonly cough and cold. Most people dread the change of seasons from one temperature to another because of the fear of how their body will react to the weather change. Be it extreme hot or cold, most people end up with a cough and cold. The more affected age groups again are the children and the elderly. However, all it takes to prevent this is to plan a little so that the body can get used to the change and not react with a cough or cold.

Prevention: There are few things that can be done which can help avoid catching cold.
1. Avoid sudden exposure to cold, from a heated room to the cold outdoors, especially in the evening and morning. Those who are used to a morning and evening walk may have to change the routine.
2. Avoid cold food items such as cool drinks, milk shakes and ice-creams.
3. Having a warm bath, early morning and late evening is advisable.
4. Avoid foods such as sour stuffs, pickles and fried foods.
5. Eat small, frequent meals that are prepared fresh are nutritious and of moderate temperature.
6. If there are infected people in your neighborhood, avoid being in close contact with them as you might get infected as well.
7. Wash your hands enough to keep them free of germs
8. As much as cold weather does not make you thirsty, push enough fluids so that your body stays hydrated. If water is not appealing enough, drink warm water or tea or lime.
9. Ensure the house, especially kitchen and bathroom are clean and disinfected.
10. Avoid exposure to dust and pollen as they carry lot of germs.
11. Avoid staying in a poorly ventilated room, enough circulation ensures germs are not concentrated in one room
12. Timely vaccination against flu

Treatment: Despite these measures, once the cough and cold has set in, the following are some easy remedies:

1. Steam inhalation, preferably with eucalyptus oil added to it.
2. Having warm soup with ginger and garlic added to it to soothe the throat
3. Ginger and other spices like cardamom and cinnamon can also be added to tea.
4. Lemon and honey can be added to a glass of warm water. This will soothe the throat and help fight cold.
5. Chewing Tulsi leaves can be beneficial
6. Yoga exercises such as Pranayama and Jalneti can be done to cleanse the nasal cavity, prevent sinus congestion, and clear mucus

Cough and Cold Due to Weather Change - Prevention & Treatment Tips

Diabetes is a metabolic disorder characterized by Hyperglycemia (elevated blood glucose level) due to either reduced production of insulin or the inability of the body to utilize the insulin produced. Today management of diabetes has become a prime concern. Over the winter months, diabetic patients are likely to suffer from higher blood glucose levels than during the warmer months. As the temperature drops and the sugar levels up, thus, diabetic patients should be extra careful about the temperature fluctuations or seasonal changes.The cold weather makes diabetics experience many health problems, besides creating a major change in their sugar levels.

Following are the most harmful effects that diabetic patients may suffer from during the cold weather

Change in hemoglobin level: There is a great change in their glycated hemoglobin levels. Whatever the type of diabetes an individual has, the freezing temperature can increase the level of HbA1c or glycated hemoglobin. This is most likely because of decreased physical activity. Cold weather makes it difficult for some people to go out. A little activity each day can help with insulin sensitivity (in all types of diabetes) which can help the body to regulate sugar level in a better way.
Prone to diseases: Since the immune system is also not at its best strength in winters, there are increased incidences of microbial infections like cold and flu or in some cases pneumonia. As a result, the body produces counterregulatory hormones (Cortisol, Adrenaline, and Glucagon) to counteract the situation. These hormones affect the utilization of insulin by the body thereby elevating the blood glucose level. Also, conditions like flu and cold tend to make them feel lethargic and stress and can prevent them from taking the diet, which is required, which eventually can lead to an increase in the blood sugar level.
Winter blues: It is often seen that people feel low during winters, as they tend to go out less and prefer to stay indoors. Less outdoor activity during winters can sometimes trigger mood swings or in some cases depression, which in turn can shoot up the level of blood sugar in their body. Thus it is advisable that one should spend more time with friends and family, in order to keep these blues at bay. 
Other problems: Most diabetic people are unaware of their nerve functions, and are unable to feel the difference between the cold and hot water, which can lead to burn injury. Also, during the winter season, most diabetic patients tend to lose feeling in their toes and feet due to vascular changes. Therefore, it is advisable that people should check their feet frequently, so as to ensure that there is no open wound or pressure area in their feet. One must take very good care of their feet, keep them moisturized, inner fingers clean and dry, prevent any type of fungal growth in toes, etc. By taking required preventive measures before the onset of winters diabetic patients can control their blood sugar level, which enables them to stay away from associated problems. 
In case the blood sugar level goes beyond 130, one should not take the medicine on their own but should get in touch with their endocrinologist (diabetologist).

Cold Weather - How It Can Affect Diabetic Patients?

There are a variety of reasons why a person can fall sick. A good number of these illnesses cannot be prevented though a person may take general precautions. Having said that, in the case of influenza, it can be prevented to a large extent and it does not seem all that smart to avoid taking easy precautions when one has an option, right?

Every year, thousands of people die from influenza, which is so unfortunate because an annual shot can reduce that number by almost 60 percent. So what exactly makes a flu shot or vaccine work? As a result of the vaccine, after about two weeks or so, antibodies begin to develop in the body. These antibodies help fight off infection, specifically the kind that is targeted by the vaccine. It is important to get vaccinated for this flu on an annual basis.

Choosing the right flu shot
Considering the great number of options there are when it comes to flu vaccines, which are the ones to be injected? It is a good idea to get the opinion of a doctor to see which one to choose. This is because the choice is dependent on a variety of factors, which a medical professional would be able to assess appropriately. Note that it is important not to use the nasal spray version of the vaccine as the medical authorities have recently found that it is not as effective a method as it once was.

When should you get it?
Flu season does vary across the world, but in the US, it starts in about October and goes on till May. During this time, the flu viruses are a lot more active. When one gets a flu shot, it is this period that one needs to look out for. So, it is better to get vaccinated in late September or the start of October, so that there is minimal unprotected exposure to the viruses.

Who is it for?
It is to be kept in mind that every individual who is older than six months should be vaccinated. While it is said that getting a vaccine shot year after year reduces its effectiveness, it is still important to do so. This is because each year, the shot is altered to reflect the biggest virus threats in that year. There might be few side effects of the flu vaccine such as redness in the injected area, soreness or swelling. However, as long as one gets a flu shot in time, it is almost a given that there will be almost no time spent  down with the flu .
