Allergy to house dust mites
House dust mites are the most common cause of asthma, allergic rhinitis and sometimes eczema. In Malaysia, house dust mites are found in all localities surveyed with 80% homes containing several species of mite in high numbers. In one Malaysian study, millions of mites were found multiplying in the mattresses of most homes throughout the country. The two most prominent house dust mites found locally are Blomia tropicalis and Dermatophagoides pteronyssinus. These two species have unique allergens that do not cross-react and should preferably be tested separately in a patient suspected of house dust mite allergy. About 85% of patients allergic to dust mites react to both species but the other 15% react to one or the other species.

Dust mites feed mainly on skin scales (derived from humans or mammalian pets), fungi, hair/fur and body fragments of dead insects. The life span of the adult mite is about 2 to 3 months and during this period it will lay about 50 eggs per month. These eggs hatch and mature in about twenty-five days in the tropics. The major allergen of the house dust mite is derived from the fecal pellets (each dust mite defecates about 50 pellets daily) and dead dust mite parts. The fecal pellets are about 20 microns in size and can reach the upper airways of people breathing them. Fecal allergens contain enzymes that allow the allergen to penetrate mucosal surfaces rapidly and cause immune allergic sensitization.

Exposure to high levels of house dust mite allergens during infancy increases the risk of allergic sensitization and the development of asthma in later life. In Malaysia about 90% of children with asthma or allergic rhinitis are positive for house dust mites. In adults with asthma the prevalence rate of mite sensitization is close to 70%. Many adults with non-specific chronic cough are often positive to house dust mite allergens. Many patients with eczema also react to house dust mites. All patients with asthma or allergic rhinitis should undergo allergy tests for house dust mites to identify the causal factors for long term management of their clinical symptoms. Many studies have emphatically demonstrated that reduction of exposure to the mites in the home environment significantly lead to the improvement of allergic symptoms. One company in Malaysia has experience in home management of house dust mites. They also supply allergy products (mattress/pillow allergicovers, anti-dust mite sprays and air-filters.)

As said earlier, those reports of autism has not been proven so, rest assured that it is safe to go ahead with the vacine.

They have done a lot of research on the combined MMR vacines so , it is safe-lah! After all, isn’t it better? The kids don’t have to suffer 3X!

Yes, when we were young , measles, mumps etc is the common childhood disease but today, we have the option of immunisation in the form of vacines and these disease may cause serious problems . Sure, even after vacines, kids may still get it, but if they do, at least it won’t be serious. In our goverment effort to get rid of this disease, goverment hospitals is now giving free MMR jab these days. Yeah! I think we should follows every shot recommended by the hospital

Luckily, chicken pox is a once in a life-time thing. Otherwise, I don’t think I can go through another one again ever! I got the virus 4 months after I delivered J Y. (Two months before that, I got an appendicitis operation)….It was terrible…I got fever for two days before dh discover some red ‘benjol’ spots on my body. I have to leave JY at my mom’s place for 2 weeks plus….it’s like the saddest days of my life. I cried for a few days because I missed my baby so much and also because of the persistent headaches that occured. I also looked the ugliest at that time….My face hit the worst…Every one day is like forever…sometimes, I so tak sabar-sabar towards the end , I start to ‘kopek’ the dried crust. So, I really don’t want my children to go through such a terrible ordeal…. definetely not at my age lar. I heard younger children will go through easier period with this virus, that’s why dh also thinks no need to go for the chicken pox jab yet. But I think I will still send JY for the immunisation.
I’m a Kiasu mom, but I think I will have no qualms in having my son vaccinated when he is due for the MMR jab.

As there is no scientific evidence, which supports the correlation between MMR vaccine and autism. The MMR vaccine, just like any other immunization shots is administered to prevent children from being exposed to potentially deadly and serious diseases.

If we choose not to give our child the MMR jab, that would make him more susceptible to measles. Measles outbreak have recently been found occurring in the UK and Germany following an increase in the number of parents who chose not to give their children the MMR vaccine. Discontinuing a vaccine program based on unproven theories would not be in anyone’s best interest I believe. Splitting the vaccine into three doses would mean more discomfort for the children too.

Just imagine if the rubella vaccine was to be delayed, approximately 4 million children would be vulnerable to rubella for an additional 6 to 12 months. This would potentially allow congenital rubella syndrome (CRS) to occur through transmission of rubella from infected children to pregnant women. Ironically, infection of pregnant woman with “wild” rubella virus is one of the few known causes of autism. Thus, by preventing rubella infection of pregnant women, MMR vaccine also prevents autism.

Vaccination

This topic is popular in our forum at MyMomsBest under Childcare. Questions asked includes:

*
What is the recommended vaccination schedule?

The below is a guideline from a private hospital. There may be slight variations depending on each hospital’s policy.

At birth BCG, Polio, Hepatitis B
1 month 2nd Hep B
2-3 mths 1st DTa P*, Polio & Hib
3-4 mths 2nd DTa P, Polio & Hib
5-6 mths 3rd DTa P, Polio & Hib
6 mths 3rd Hepatitis B
> 12 mths Chicken pox
12-15 mths MMR
18 mths DTa P, Polio & Hib – 1st booster
5 years MMR Booster
4-6 years DTa P, Polio – 2nd Booster

*
Is my baby going to be sick or in pain after the jab?

Not every vaccination is going to cause fever and pain. However, there are certain jabs that may make a baby feverish. Usually, the doctor will prescribed some paracetamol for your child after taking jabs like DaTP/Polio/Hib, chicken pox, MMR .

* = DTa P (Diptheria, Tetanus & Pertussis combination vaccine) a stands for acellular is a new improved version of vaccine which has been shown to cause less side effects, such as fever, painful swelling, fits, etc. But DTaP is more expensive compare to the older version. Only the private hospitals are using it.

*
I heard that there are two options to polio vaccine. What are those?

Polio drops are commonly given by dropping the vaccine in liquid form into the baby’s mouth. The other alternative is the injectable killed polio vaccine. Compared to the widely used oral live attenuated polio vaccine, the new generation injectable polio vaccine has less vaccine-associated complications.

*
What is BCG for? Why does it produce a scar?

BCG is to prevent TB, especially TB meningitis and a severe form of TB in the lungs (called miliary TB) in young children. It is just the nature of the vaccine which produce a very intense immune reaction on the injection site, hence resulting in a scar. Some may even have keloid formation. The scar is a clinical evidence to prove that the person has been given the BCG jab. Some countries health ministry gives BCG at the buttocks purely for cosmetic reasons.

*
I heard that if I bring my child for the Hib vaccination at an older age, he will get less jabs. Is this true?

Since May 2003, government clinics have started giving HiB vaccines to newborn babies. It is incorporated with the DTP/Polio vaccine according to the Malaysian immunisation schedule at 2,3 & 5 months. For those who has not received this vaccine, the schedule is as follow:….
Between 1-6 months, a baby will be given 3 jabs
If a baby is above 6mth and below 12 months, need 2 jabs
Once a child is above 1yr or up to 4 yrs old, need 1 jab

It is advisable to get a baby vaccinated against Hib (an infection affecting the brain) from an early age because of the severity of the illness. Otherwise, it can be too late for treatment when diagnosis is delayed. The jab given to a smaller baby is in a smaller dosage and thus, more repeats are required.
