Vaccine Myths shattered !

In this modern era of Internet and net savvy parents, many of these concerned parents have some queries / objections regarding vaccines.
These are increasing on a daily basis due to many factors, including increasing number of newer vaccines, newspaper / media reports (generally factually incorrect, I may say) regarding potential side-effects, and genuine concerns regarding the effect of so many vaccines on the child's immune system.
I would like to shatter a few of the common misconceptions regarding vaccinations using this forum.

Myth: it’s better to develop natural immunity then get vaccinated.

Fact: the difference between vaccination and natural infection is the price paid for immunity. The price paid for natural immunity (infection) is the physical economical & mental agony the entire family goes through after one suffers from a disease. In comparison price paid for vaccination is negligible. Also it is important to remember that many of the diseases that we getting protected against can actually cause a large number of complications including death of a child. In fact thousands of children die in India every year due to vaccine preventable diseases, hence getting a vaccination done is preferable to allowing 'natural immunity' for most diseases.

Myth: by relying on vaccines, my child’s immune system becomes weak or does not develop at all.

Fact: No, vaccine do not weaken immune system. People generally believe that vaccines offer ready made protection. This is NOT the case. In fact the vaccines work like a 'mini-disease'. The body acts on vaccine germs and produces antibodies, which fight against disease germs when the child comes in contact with disease any time in future.

Myth; vaccines are known to cause serious side effects.

Fact: In most cases, vaccines cause no side effects or only mild reactions such as fever or soreness at the injection site. Very rarely, people experience more serious side effects like allergic reactions. Be sure to tell your doctor if your child has had any severe reaction to previous vaccine, or has health problems or known allergies to medications or food.

“Vaccines”- Yes But how many ?

As you know, prevention is always better than cure. Fortunately, due to progress in vaccine science & technology, it is possible to protect children against several serious diseases through vaccination; normally a baby is exposed to millions of germs daily. It is much better to protect them against diseases through vaccination then let them be at risk & suffer.

Myth: My child does not require vaccines, as he/ she is healthy, active & eats well.

Facts: vaccination is intended to help keep kids healthy, because vaccines work by protecting the body before disease strikes. If you wait until your child gets sick, it will be too late for the vaccine to work. The best time to immunize kids is when they’re healthy.

Myth: Combination vaccines cause more side effects.

Fact: Combination vaccines are as safe & effective as individual vaccines there are two practical factor in favor of giving a child several vaccines during the same visit. First, to immunize children as early as possible to give protection during the vulnerable early months of their lives.

Second, giving several vaccines at the same time will mean fever clinic visits & fewer injections, which saves parents both time and money and may be less traumatic for the child. There are studies done that show that the discomfort caused is less with combination vaccines as compared to individual shots.

Just think - what would you want for yourself - 3 injections separately or a single injection containing all 3 vaccines ?

Myth: It’s OK to skip certain vaccine.

Fact: In general skipping vaccines is not a good idea. This can leave your child vulnerable to potentially serious disease that could otherwise be avoided. If you have reservations about any particular vaccine, discuss your concerns with your child’s doctor, if your child falls behind the standard vaccination schedule, catch-up vaccination is also available.

Myth: If I have missed a dose of any vaccine, it is no longer needed later

Fact: For most vaccines, if the dose is missed on the due date, you still need to take it at any later date (catch - up vaccination). Talk to your doctor regarding when these doses should be completed.

Myth: Vaccine may not be 100% effective; so why vaccinate?

Fact: Vaccines indeed are the most effective weapons we have against diseases. They work in 85% to 99% of cases. Smallpox has been eradicated from the face of earth & a dramatic reduction in the incidence of diseases like Polio, Diphtheria, Pertussis, Measles & Mumps are evidence of power of vaccines. Vaccine failure is rare & in such a case the disease is usually milder.

Myth: vaccines are for babies only. There is no need to vaccinate after 2 to 4 years of the age.

Fact; Diseases continue to affects school going children, adolescents & adults. It is always better to keep your child protected. Few vaccines (like DPT) do not provide life long protection. Protective efficacy of these vaccines wanes off over a period of time so regular boosters are required.

There are some new vaccines (like HPV) for adolescent girls to prevent Cervical Cancer. Some vaccines (like Flu) need regular vaccination as the virus keeps changing. For most of the vaccines age is not a barrier. Ask your doctor if you have missed any vaccine as you can always catch-up.

A friendly reminder for parents:

Adults need vaccination too! Check with your doctor to know what vaccines you might need. Your baby is counting on you.

Frequently asked questions regarding vaccines

What is vaccination?

Vaccination protects children against serious diseases by stimulating the immune system against disease germs.

How does vaccine immunity differ from natural immunity?

Normally in most diseases the disease-germ enters the body, produces the disease & the body mounts fighting power against the germ and lastly one recovers from the disease. Here immunity against disease is produced after one has suffered from the disease.

A vaccine is nothing but whole or part of the disease germ, which has been processed or modified in such a way that it loses its capacity to produce disease but it can still induce fighting power in the body when administered. Hence by vaccination one develops immunity without suffering from the disease.

Rather than reinvent the wheel, I have decided to post a list of excellent detailed FAQs that interested parents can go to and read.

Influenza Vaccine - Now Available for season 2009 -2010 in India - FAQs

Influenza (also called "the flu") is a viral infection in the nose, throat and lungs. About 10 to 20 percent people get the flu each year. Some people get very sick. Tens of thousands die every year in India because of the flu and complications.

What are the Symptoms of FLU?

The flu may cause fever, cough, sore throat, a runny or a stuffy nose, headache, muscle aches and tiredness. Some people describe the flu as the worst cold of their life. If you get the flu, you should feel better after one or two weeks. But in some people, the flu leads to serious, even life-threatening diseases, like pneumonia. Some people are more likely to get the serious complications. A vaccine (the flu shot) is recommended for these high-risk people to protect them from the flu.

Who is at higher risk?

You have a higher risk of flu complications if you:

  • Less than 5 years age
  • Are 60 years of age or older
  • Are a doctor, nurse or working in a hospital
  • Have a lung problem, such as asthma or emphysema
  • Have Diabetes
  • Have a suppressed immune system
  • Have a problem with your kidneys
  • Have heart disease or other long-term health problems

If you are in any of these risk groups, you should get the flu vaccine every year.

Even if you're not at higher risk, you may want to get the flu vaccine so you don't get sick with the flu.

What is the flu vaccine?

The flu vaccine is an injection. It contains killed viruses. You can't get the flu from the vaccine because the viruses are dead. Instead, the vaccine protects you from the flu. When a "live" virus shows up, your defenses are ready. These defenses keep you from getting the flu. Because flu viruses change from year to year, you must get the shot each year to be protected.

When should I get the vaccine?

You should get the vaccine at the beginning of the flu season, sometime in September onwards. You can get the shot later in the year too, but because flu season usually begins in the winter months, it would be best to be protected before that time.

If I get a flu shot, can I still get the flu?

Yes. Even with a flu shot, you aren't 100 percent protected. Each year, the flu vaccine contains three different strains (kinds) of the virus. Depending on the strains used, the Flu vaccine is 70 to 90 percent effective in preventing the flu in healthy people under 65 years of age. If you're older than 65, the vaccine is less likely to prevent the flu. Even if you get the flu after the vaccine, your flu symptoms should be milder than if you didn't get the vaccine. You'll also be less likely to get complications from the flu.

Is the vaccine safe?

Yes. The flu vaccine is safe for all age groups over six months of age. There are very few side effects too. Your arm may be sore for a few days. You may have a fever, feel tired or have sore muscles for a short time. If you have a severe allergy to eggs, you shouldn't get the shot.

Do you take the FLU vaccine?

Yes, I have personally been taking the FLU vaccine for the last 3 years, ever since it was made available in India.

Will the vaccine be effective against swine flu?

As of now we do not really know, however we must remember that Seasonal Flu kills far more people than Swine Flu, and it is as serious a disease. For the high risk people mentioned above, taking this vaccine is a great way to reduce complications from this common disease.

The Three C's of Medical Marketing

The other day I had a very interesting experience with a pharmaceutical company representative from a leading Indian Vaccine manufacturing company.
He came to me, and showed me a document, extracted from the WHO website, claiming that their Tetanus vaccine was the ONLY WHO approved Tetanus vaccine in India.
After looking at the document, I pointed out that the same document clearly showed that this was not true, and another older Indian Vaccine Company also had WHO approved Tetanus vaccine!
He coolly said, “Sir, but our vaccine is Air couriered to the destination, whilst there vaccine comes from Land Transport!”.
This was quite beside the point and I told him so. Similar misleading statements / outright lies have been made by other Medical Representatives.
At this point of time, I said, “ I believe that all Med Reps go to the same school, wherein you are told to change the topic / confuse the doctor as soon as you are caught out”.
He smiled and revealed a trade secret, he said, “Sir, it is the case of 3 C’s”.
What are these 3 C’s?
CONVINCE a Doctor.
If that does not work CONFUSE him.
And if that fails too, CORRUPT him, by offering incentives to him.
I found this amusing and worrying at the same time, like many truths, I suppose.
Is this how one of our most closely allied profession views us?
And more importantly, are they wrong?
Isn’t it we who have helped create this image?
