We have created a two-tiered system where the rich buy protection, the poor catch it.
In Malaysia, two pediatricians are challenging a deeply held cultural assumption — that chickenpox is a harmless childhood rite of passage — by calling for its vaccine to be included in the national immunization program. The disease causes serious complications in otherwise healthy children, threatens pregnant women with devastating fetal outcomes, and exposes immunocompromised patients to lethal risk, yet protection remains available only to those who can afford private care. As other nations have already demonstrated that routine vaccination dramatically reduces hospitalizations and death, Malaysia faces a question that is as much ethical as epidemiological: how long can a preventable burden be allowed to fall disproportionately on the poor?
- Chickenpox is hospitalizing healthy Malaysian children with pneumonia and brain inflammation — conditions most parents never knew the virus could cause.
- Immunocompromised children face potentially fatal exposure every time an unvaccinated peer brings the virus into a classroom or home.
- A two-tiered vaccination system means wealthier families quietly buy protection in the private sector while lower-income families are left to absorb preventable suffering and death.
- Concerns that mass vaccination might increase adult shingles decades from now are being weighed against the certainty of ongoing childhood hospitalizations — a trade-off the pediatricians argue is ethically untenable.
- The call is direct: add the varicella vaccine to Malaysia's National Immunisation Programme, following the path already taken by the US, Germany, and Australia with measurable success.
A healthy five-year-old's rash turned into high fevers, severe dehydration, and an emergency room visit — a scenario that two Malaysian pediatricians, Dr Musa Mohd Nordin and Dr Zulkifli Ismail, say is far more common than the country acknowledges. They are pushing back against the widespread belief that chickenpox is a benign childhood inevitability, arguing that Malaysia is treating a preventable public health crisis as a rite of passage.
The complications are real and they fall primarily on otherwise healthy children: pneumonia, infected sores, brain inflammation. For children on chemotherapy or living with HIV, contact with an unvaccinated peer can be fatal. Studies also show low varicella antibody levels among Malaysian young adults, meaning a growing cohort has no natural immunity — and when the virus reaches them, the consequences include viral pneumonia, hepatitis, and weeks of incapacity. Infection during pregnancy carries the risk of Congenital Varicella Syndrome, causing limb deformities, brain damage, and eye defects in newborns.
Malaysia's current system compounds the problem. The vaccine exists only in the private sector, accessible to families with the income or medical literacy to seek it out. Poorer families receive an implicit message: let your child catch it. The pediatricians frame this not merely as a health gap but as an ethical failure, with costs measured in hospitalizations, scarring, missed schooling, parental leave, and preventable deaths.
One counterargument holds that mass childhood vaccination could reduce natural immune boosting in the community, potentially raising shingles rates in adults years later. The pediatricians answer plainly: it is not ethical to allow millions of children to suffer acute varicella for the next quarter century based on a manageable, theoretical future risk — especially when a safe shingles vaccine already exists. The United States, Germany, and Australia made routine varicella vaccination standard and saw hospitalizations and deaths fall sharply. The call to Malaysia's Ministry of Health is unambiguous: add the varicella vaccine to the National Immunisation Programme, and stop treating a preventable disease as an acceptable part of growing up.
A neighbour's healthy five-year-old came home with what looked like the usual rash. Within days, the child was running high fevers, severely dehydrated, and making a frantic trip to the emergency room. It was chickenpox—a disease most Malaysians have been taught to accept as an inevitable, harmless part of childhood. But two paediatricians, Dr Musa Mohd Nordin and Dr Zulkifli Ismail, are pushing back against that assumption with urgency, arguing that Malaysia is treating a preventable public health crisis as though it were merely a rite of passage.
The myth of chickenpox as benign has deep roots. Most parents expect their children to catch it, suffer through it, and emerge with lifelong immunity. The reality is far more complicated. Serious complications—pneumonia, infected sores, brain inflammation—occur primarily in otherwise healthy children, not just in the immunocompromised populations most people assume are at risk. For children undergoing chemotherapy or living with HIV, exposure to an unvaccinated peer can be lethal. A recent Danish study suggested that the true burden of varicella in developed health systems is far higher than official records indicate when you account for primary care visits and the full weight of suffering. Malaysia has no reason to believe it is exempt from these patterns.
The problem extends beyond childhood. Studies reveal low levels of varicella antibodies among Malaysian young adults, meaning a growing cohort never developed natural immunity. When an infected child brings the virus home to an unimmunized parent, the consequences can be severe: viral pneumonia, hepatitis, weeks of incapacity. Varicella in adults is not merely uncomfortable. It is dangerous. Then there is Congenital Varicella Syndrome—infection during pregnancy leading to limb deformities, brain damage, and eye defects in newborns. This outcome is entirely preventable, yet it continues to occur.
Malaysia's vaccination system has created a two-tiered structure that mirrors and reinforces economic inequality. The varicella vaccine exists in the private sector, accessible primarily to families with higher education, higher income, or medical knowledge. Poorer families are left with the implicit message: just let your child catch it. This is not merely a health gap. It is an ethical failure. The costs accumulate in Quality Adjusted Life Years lost to suffering, scarring, missed school days, parental leave, febrile seizures, sleepless nights, and preventable deaths.
Some hesitation centres on a theoretical concern: that mass childhood vaccination might reduce natural boosting in the community, potentially increasing shingles (herpes zoster) in adults decades later. But the paediatricians pose a direct question: is it ethical to allow millions of children to suffer acute varicella—including hospitalizations and deaths—for the next 25 years based on a manageable, theoretical risk to future adults? A safe zoster vaccine already exists for the elderly. Countries like the United States, Germany, and Australia have made routine varicella vaccination standard and dramatically reduced hospitalizations and deaths as a result. They did not wait for chickenpox to prove itself a killer.
The call is clear and specific: add varicella vaccine to Malaysia's National Immunisation Programme. Until that happens, every parent who can afford the private shot should request it. Every doctor should recommend it not as an optional luxury but as standard care. The paediatricians are asking the Ministry of Health to acknowledge what the World Health Organization has long supported—that routine varicella vaccination is justified where resources allow. No child deserves to suffer from a disease we already know how to prevent.

La Conversación del Hearth Otra perspectiva de la historia
Why does chickenpox still feel like a normal childhood experience to most Malaysians?
Because we've normalized it. For decades, the narrative has been that catching it young is better than catching it later. That myth persists even though the data shows serious complications happen in healthy kids, not just vulnerable ones.
But doesn't natural immunity last longer than vaccine immunity?
That's a fair question, but it misses the point. Yes, natural infection provides lifelong immunity. But the cost of acquiring that immunity—hospitalization, pneumonia, brain inflammation, or in rare cases death—is not worth avoiding a vaccine dose.
What about the shingles concern? Doesn't vaccination increase that risk later?
It's a legitimate theoretical concern, but it's being used to justify letting millions of children suffer now. We have a safe zoster vaccine for older adults. The math doesn't work in chickenpox's favour.
Why is the private-only system so damaging?
Because it means wealthy families buy protection while poor families are told their children should just catch it. That's not public health. That's rationing suffering by income.
What would change if varicella went into the national program?
Suddenly every child gets protected, regardless of their parents' income or education. You eliminate the two-tiered system. You prevent hospitalizations, brain damage in newborns, and deaths in immunocompromised kids. It's straightforward.
Is there political will to make this happen?
That's the question. The WHO supports it. Other countries have done it successfully. But Malaysia hasn't moved yet. The paediatricians are essentially saying: how many more preventable cases do we need to see?
