Why Do We Need Two Doses Of Vaccine?

Why do we need two doses of vaccine?

Vaccination is a two-fold protective measure for preventing illness. The first dose alerts the immune system to the presence of a certain virus or bacterium, and it creates a cellular immunity of sorts. The second dose is required to alert the body's antibodies, which are typically slower acting but more powerful bodies of defenses. These antibodies present themselves naturally in our bodies after vaccination, forming what we know as "natural specific immunity." To get that natural specific immunity from your second vaccination shot, you will need both injections at least six weeks apart. Essentially then, getting vaccinated twice in quick succession has no effect on your ability to build up natural specific immunity because you'll already be protected by cellular-specific immunity when you receive your second one.

The second dose helps to reduce the incidence of infectious disease. A major reason for a second dose is "herd immunity," in which a high proportion of people within a population have been vaccinated to provide what is known as "community protection" against an infection's spread. This limits the number of individuals who might otherwise be vulnerable or susceptible to contracting and transmitting infection. For this reason, everyone needs to do their part in making sure their own vaccinations are up-to-date and take care does not infect others when they're around them with compromised immune systems--primarily infants too young to have ever been vaccinated or anyone who cannot get vaccines for medical reasons such as being immunosuppressed.

The second dose of the vaccine introduces a different version of the virus into your system to allow your body to develop an immunity because not all viruses are 100% susceptible to the first vaccine.

The effectiveness of vaccination does decline over time, so another injection can help prolong immunity for 5-6 years before it's necessary to vaccinate again. It may be because there are different versions or "strains" or versions of viruses that vaccines don't always work well on. Or there are definitions for "immunity" that are different from ours - whether you have antibodies in your blood doesn't always show true protection against an infection! Of course, we recommend asking a medical professional if you're really interested in this question.

Reason #1: Whether an individual had natural immunity previously. The first shot could wear off for some people, so the second dose ensures that there is protection long after the first dose has worn off.

Reason #2: Some children do not develop strong enough immunity when given just one vaccine dose or they received their vaccines too early in life and later required a booster shot so the best way to protect them is with two doses.

Third Medic Medical consultation online To improve chances of inducing protective immunity in unvaccinated groups during outbreaks, it may be advisable to administer two doses of vaccines to maximize coverage among these populations The cold virus mutates extremely rapidly, and your chances of contracting a mutated strain of cold virus from the vaccine are higher if you skipped the first round. The goal here is to vaccinate as many people as possible with a vaccine that is most likely going to protect them from infection. That’s because even if 50% of those vaccinated this year will not be protected from contracting the disease, that 50% who do end up not being able to contract it are still more protected than they would have been had there been no vaccination. If you argue that vaccines don't work, then you are arguing that children should go untreated for deadly diseases because populations can never get rid of all illnesses at once!

This is a two-fold concern. First, we're aiming to create immunity against the disease more rapidly and it appears that this isn't accurate if we only vaccinate once; we need to boost with two doses at least one month apart. Second, because there are limitations in the science behind vaccination, it's difficult to tell who will have the highest reaction or reaction frequency. So for absolute safety, most doctors recommend three doses at any point in life for those who've never been vaccinated before

Second dose of the vaccine is to confer "immunity." If you happen to be exposed to a virus or bacteria and recover, your body will remember and create antibodies for that specific infection. A second dose of the vaccine provides enough time for those immunities to build up.

If you take the first dose, and go out right afterward to play with friends--this could lead the immune system into mistakenly attacking your own tissues as if they were infected as well because it doesn't yet know not them as healthy tissue.

The first dose is more or less a "primer" and the second dose corresponds with the timing of the typical infectious disease infection. Estimating how long it takes for immunity to develop also depends on which vaccine is being administered. Different viruses elicit variable immune responses, which means that they need different types of vaccines to work best. It's been found, for instance, that most people who receive an influenza vaccination require two doses about four weeks apart to fight off the flu properly. In addition, live attenuated influenza vaccine spurs fewer immunological side effects because it contains weakened versions of elements from virus strains already circulating among humans – since those factors are weaker than their intact counterparts found in a regular flu shot or nasal spray.

The two-dose vaccine regimen is a tried and tested method showing excellent effectiveness.

Best Treatment Options for IBS in India

Best Treatment Options for IBS in India

Irritable Bowel Syndrome (IBS) is a common digestive condition that affects millions of people across India. If you often suffer from stomach pain, bloating, constipation, or diarrhea, you may be dealing with IBS. While it can be frustrating and affect your daily life, the good news is that IBS can be managed effectively with the right approach.

In this blog, we will cover the best treatment options for IBS in India, from diet changes to ayurvedic solutions and advanced diagnostic tests.

 

What is IBS?

IBS (Irritable Bowel Syndrome) is a chronic digestive disorder that affects how your gut functions. Unlike other diseases, IBS doesn’t damage the digestive tract, but it causes uncomfortable symptoms that come and go.

 

Causes of IBS

The exact cause of IBS is not fully understood, but common factors include:

  • Gut-brain axis dysfunction
     

  • Stress and anxiety
     

  • Hormonal changes
     

  • Food intolerances (e.g., lactose, gluten)
     

  • Gut infections
     

  • Poor dietary habits
     

 

Common Symptoms of IBS

  • Abdominal pain or cramps
     

  • Gas and bloating
     

  • Diarrhea, constipation, or both
     

  • Changes in bowel movements
     

  • Mucus in the stool
     

  • Fatigue or sleep problems
     

Symptoms vary for each person and often get worse after eating or during times of stress.

 

Best Treatment Options for IBS in India

IBS treatment focuses on relieving symptoms, as there is no one-size-fits-all cure. Here are the top treatment approaches used across India:

 

1. Dietary Changes

One of the most effective ways to manage IBS is through food:

Follow the Low FODMAP Diet

FODMAPs are carbohydrates that are hard to digest and cause gas. The Low FODMAP diet helps reduce symptoms by eliminating:

  • Onions, garlic
     

  • Beans, lentils
     

  • Dairy
     

  • Wheat
     

  • Processed foods
     

Slowly reintroduce foods with the help of a nutritionist.

Eat Small, Frequent Meals

Instead of large meals, eat smaller portions 4–5 times a day.

Stay Hydrated

Drink 8–10 glasses of water daily to ease digestion and prevent constipation.

 

2. Probiotics and Supplements

Probiotics are good bacteria that help restore balance in your gut.

  • Brands like Darolac, Sporlac, VSL#3 are commonly used in India.
     

  • Fiber supplements (like Isabgol) help relieve constipation.
     

  • Peppermint oil capsules may soothe gut muscles.
     

Always consult your doctor before starting supplements.

 

3. Prescription Medications

Depending on the symptoms, doctors in India may prescribe:

  • Antispasmodics (e.g., Drotaverine, Mebeverine) – for cramps
     

  • Laxatives (e.g., Lactulose) – for constipation
     

  • Anti-diarrheal drugs (e.g., Loperamide) – for diarrhea
     

  • Tricyclic antidepressants – to reduce gut sensitivity
     

Medication should be used only under medical supervision.

 

4. Ayurvedic Treatment for IBS

India offers powerful traditional options through Ayurveda. Herbs used include:

  • Kutaj – for diarrhea
     

  • Bilva – for digestion
     

  • Triphala – for bowel regularity
     

  • Jeeraka and Musta – reduce bloating
     

Ayurvedic treatment focuses on balancing the vata, pitta, and kapha doshas. Always choose certified practitioners.

 

5. Stress Management Techniques

Since stress and anxiety worsen IBS, it’s important to care for your mental health:

  • Yoga – especially poses like Pawanmuktasana and Vajrasana
     

  • Meditation and Pranayama
     

  • Cognitive Behavioral Therapy (CBT)
     

  • Counseling for teenagers or working professionals under pressure
     

Mind-body techniques are especially useful in Indian urban settings.

 

Recommended Lab Tests (Available on SecondMedic with Thyrocare)

To rule out other conditions and get clarity on your gut health, the following tests are helpful:

  1. Thyroid Profile (T3, T4, TSH) – to rule out hypothyroidism
     

  2. Vitamin D & B12 Tests – deficiencies can mimic IBS
     

  3. Liver and Kidney Function Tests – rule out other digestive diseases
     

  4. Stool Occult Blood Test / Calprotectin – if symptoms persist
     

  5. Aarogyam C Panel by Thyrocare – a full metabolic and vitamin panel
     

These tests are available at affordable rates with home sample collection via SecondMedic.

 

When to See a Doctor

Consult a gastroenterologist if:

  • Your symptoms last more than 4 weeks
     

  • You see blood in stool
     

  • You have rapid weight loss
     

  • You're losing sleep due to stomach pain
     

Early diagnosis prevents long-term damage and reduces emotional distress.

 

IBS Products Commonly Found in India

  • Isabgol (Psyllium husk) – for fiber
     

  • Probiotic sachets – Darolac, Vizylac
     

  • Ayurvedic syrups – Baidyanath Abhayarishta, Himalaya Triphala
     

  • Peppermint capsules – natural antispasmodic
     

  • Stress-relief teas – chamomile, tulsi
