Vaccinated Against HPV? You Still Need Cervical Screening
中文摘要在文末
This is the most important article in this section, and it's about something we don't provide.
We offer HPV vaccination. We do not offer cervical screening. And we'd rather send you somewhere else for screening than have you leave here believing an injection covered everything.
The misconception
It goes like this: I've had the HPV vaccine. HPV causes cervical cancer. So I'm protected, and I don't need pap smears.
Every step sounds reasonable. The conclusion is wrong, and it's dangerous — because a woman who believes it may skip screening for a decade or more, which is exactly the period during which cervical changes develop silently and are most treatable if found.
A vaccinated woman who never gets screened can end up worse off than an unvaccinated woman who screens regularly.
Here's why the reasoning fails.
Two reasons the vaccine doesn't replace screening
1. It doesn't cover every type.
Gardasil-9 protects against nine HPV types — the ones responsible for the large majority of cervical cancers, but not all of them. "Large majority" is not "all," and the remainder is exactly what screening is for.
2. It prevents new infection. It does nothing about past exposure.
The vaccine works before exposure. If you'd already encountered a high-risk type before vaccination, the vaccine doesn't clear it, doesn't reverse it, and doesn't stop it progressing.
This matters most for adults vaccinated later in life, where the chance of prior exposure is higher. Someone vaccinated at 35 has a meaningfully different risk profile from someone vaccinated at 12 — and paradoxically, the adult who feels newly protected may be the one most in need of continued screening.
Vaccination and screening do different jobs
It helps to see them as two separate defences rather than alternatives.
Vaccination is primary prevention. It stops infection happening in the first place. It works forwards in time and it works best before exposure.
Screening is secondary prevention. It finds changes that are already present, early enough to treat them before they become cancer. It works on what's happening now, regardless of what you were exposed to or when.
Neither substitutes for the other. Vaccination can't detect an existing problem. Screening can't prevent an infection. You need both.
What screening is recommended in Malaysia
Current Malaysian guidance sets out screening by age band:
Sexually active women aged 30 to 49: HPV testing. Where the HPV test is negative, the recommended interval is every five years.
Women aged 21 to 29, and 50 to 65: Pap smear screening.
Women over 65 who have never been screened: HPV testing is recommended.
The reason HPV testing is used in the 30–49 group is that it's more sensitive at detecting the infections that lead to cancer, which allows longer intervals between tests — meaning fewer tests over a lifetime, not more.
One caution about these figures. There is more than one Ministry of Health document covering cervical screening, and they don't describe the age bands identically — some guidance describes HPV testing as available across the wider 30–65 range. So don't be surprised if a clinic offers you something slightly different from what's above. Age bands and intervals are also periodically revised.
Confirm current recommendations with whoever provides your screening. The important point isn't which band you fall into. It's that you're being screened at all.
Where to go
Since we don't provide it, here's where to look.
Klinik Kesihatan. Government health clinics provide cervical screening, and this is the most straightforward route for most people. There are several across Kota Kinabalu and the surrounding districts.
A GP or O&G who provides screening. Many private clinics offer pap smears and HPV testing.
Program ROSE. This is worth knowing about specifically, because it addresses the main reason women avoid screening. ROSE is an HPV-based screening programme using self-sampling — you take the sample yourself rather than having a clinician do it, with results delivered digitally.
It was developed in Malaysia and studied here. In the pilot work, the overwhelming majority of women found self-sampling acceptable, and most said they'd prefer it to a clinician-taken sample.
If embarrassment or discomfort is what's been stopping you, this route removes that barrier almost entirely.
National Cancer Society Malaysia and various state programmes also run screening initiatives, some subsidised.
If it's the examination putting you off
Let's name this, because it's the actual reason a lot of women don't attend.
The traditional pap smear involves a speculum examination, which many women find uncomfortable, undignified, or culturally difficult. That's a completely understandable reason to avoid it — and it has cost lives, which is precisely why self-sampling was developed.
If that's your barrier, self-sampling is the answer. It's not a lesser option or a compromise; HPV-based screening is what current guidance recommends for the 30–49 age group anyway.
If cost or distance is the barrier, Klinik Kesihatan is the route to ask about.
If it's simply that you've never got round to it — the interval for HPV-negative results is five years. This is not a frequent commitment.
What we'd ask
If you come to us for HPV vaccination, expect us to ask whether you're up to date with screening, and expect us to point you towards it if you're not.
That's not us being thorough for the sake of it. It's that vaccinating someone who then stops screening would be a poor outcome, and we'd rather the two things stay connected in your mind.
And if you're a parent whose daughter is being vaccinated: the version to give her, when she's old enough, is "the vaccine substantially reduces the risk, and you still get screened." Both parts.
A generation that grows up believing vaccination alone is sufficient would be a bad outcome from a good programme.

简要说明
亚庇 Lintas Square 的 Klinik Dr Tan。
这是本系列中最重要的一篇，而它讲的是我们不提供的服务。 我们提供 HPV 疫苗接种，不提供子宫颈筛检。我们宁可把你转介出去，也不希望你以为打一针就涵盖了一切。
那个误解：「我打过 HPV 疫苗；HPV 会导致子宫颈癌；所以我受到保护，不需要做抹片。」每一步听起来都合理，但结论是错的，而且危险——相信这个说法的女性可能十年以上不做筛检，而那正是子宫颈病变悄悄发展、也最容易治疗的时期。
一个接种了疫苗却从不筛检的女性，可能比没接种但定期筛检的女性处境更差。
为什么疫苗不能取代筛检？
它不涵盖所有型别。 Gardasil-9 涵盖九种——造成大部分子宫颈癌的型别，但不是全部。「大部分」不是「全部」，而剩下的正是筛检的用途。
它预防新的感染，对过去的接触无能为力。 疫苗在接触之前才有效。如果你在接种前已经接触过高危型别，疫苗不会清除它、不会逆转它、也不会阻止它进展。这对较晚接种的成人最为重要——35 岁接种者的风险轮廓与 12 岁接种者截然不同，而讽刺的是，那位刚感到安心的成人，可能正是最需要持续筛检的人。
两者做的是不同的工作：
疫苗是初级预防——阻止感染发生，往未来生效，在接触前最有效。
筛检是次级预防——找出已经存在的变化，在它变成癌症之前及早治疗。
两者不能互相取代。疫苗无法侦测已存在的问题；筛检无法预防感染。你两者都需要。
马来西亚现行的筛检建议（依年龄分组）：
30 至 49 岁有性行为的女性：HPV 检测。检测阴性者，建议间隔为每五年一次。
21 至 29 岁及 50 至 65 岁：子宫颈抹片。
65 岁以上、从未做过筛检者：建议做 HPV 检测。
30–49 岁使用 HPV 检测，是因为它对导致癌症的感染更敏感，因此可以拉长检测间隔——一生中检测次数更少，而不是更多。
关于这些数字的一点提醒：卫生部关于子宫颈筛检的文件不只一份，而各份对年龄分组的描述并不完全一致——部分指引把 HPV 检测的适用范围写成较宽的 30–65 岁。所以如果诊所提供的方案与上述略有不同，不必意外。年龄分组与间隔也会定期修订。
请向筛检提供者确认目前的建议。重点不在于你属于哪一组，而在于你有没有在做筛检。
去哪里做：
Klinik Kesihatan（政府诊所）——对多数人最直接的途径，亚庇及周边地区有多间。
提供筛检的家庭医生或妇产科医生。
Program ROSE——值得特别一提，因为它解决了女性回避筛检的主要原因。ROSE 是以 HPV 为基础的筛检计划，采用自我采样——由你自己采检，而非由医护人员操作，结果以数位方式传送。它在马来西亚研发并研究，试办阶段绝大多数女性认为自我采样可以接受，多数人表示比起医护采样更偏好这种方式。如果让你却步的是尴尬或不适，这条途径几乎完全移除了那个障碍。
马来西亚防癌协会（NCSM）及各州计划，部分有补助。
如果让你却步的是内诊：传统抹片需要使用鸭嘴器，很多女性觉得不适、有失尊严、或在文化上难以接受。那是完全可以理解的回避理由——而它确实造成过生命的损失，这正是自我采样被开发出来的原因。如果这是你的障碍，自我采样就是答案，而且它不是次等选项——30–49 岁本来就建议使用以 HPV 为基础的筛检。
如果障碍是费用或距离，请询问 Klinik Kesihatan。如果只是一直没去做——HPV 阴性者的间隔是五年，这并不是频繁的负担。
我们会做的事：如果你来接种 HPV 疫苗，请预期我们会问你筛检是否跟得上进度，也会在你没跟上时提醒你去做。这不是多此一举——替一个之后就不再筛检的人接种，是不好的结果，我们希望这两件事在你心里始终连在一起。
如果你是家长：等女儿够大时，请给她完整的版本——「疫苗大幅降低风险，而且你仍然要做筛检。」两部分都要说。 一个从小以为接种就足够的世代，会是一个好计划带来的坏结果。
