Measles and the MMR Vaccine: Protecting Your Child, and Before You Travel

Mums and dads, if you are travelling to Thailand, do make sure that the family is vaccinated against measles...

Measles had almost disappeared from most parents’ worries, which is exactly why its return catches families off guard. It spreads faster than almost any other infection, it travels home in the luggage of an unvaccinated traveller, and it is far from the harmless childhood rash some imagine. The protection, though, is settled and it is free.

The MMR vaccine is given at 12 months and again at 15 to 18 months under Singapore’s national schedule, and two doses give strong, lasting protection. Vaccination against measles is required here by law.

Before travelling to an area with an outbreak, check your child is up to date. The unvaccinated child is the one at risk.

Why measles is worth taking seriously

Measles spreads through the air when an infected person coughs or sneezes, and a single case can infect almost everyone unprotected around it. It opens like a heavy cold, then turns:

High fever
Cough, runny nose and red, watery eyes
Tiny white spots inside the cheeks, called Koplik spots
A blotchy red rash that starts at the hairline and spreads down the body, a few days after the fever

Most children recover, but a fair number don’t get off lightly. Measles causes ear infections and pneumonia, and, rarely, brain inflammation that can leave lasting damage or kill. Babies too young for the vaccine are the most exposed, along with any child whose parents skipped it. If your child does run a fever, our guide on managing a fever in children covers the comfort measures, but measles needs a doctor, not home care alone.

The vaccine, and where it sits on the schedule

The measles, mumps and rubella (MMR) vaccine is the whole defence, and it appears on Singapore’s National Childhood Immunisation Schedule at two points:

First dose at 12 months
Second dose at 15 to 18 months

Two doses give strong, long-lasting immunity. Measles vaccination is compulsory under the Infectious Diseases Act, the vaccine is free for Singaporean children at polyclinics, and any Primary 1 pupil who missed a dose is caught up in school. If you have lost track, your child’s record lives in the HealthHub app, and the full immunisation schedule for parents lays out every jab by age.

On the old worry: the study that once linked MMR to autism was retracted and discredited, and the link has been disproven many times over. The genuine risk lies with the disease, not the jab.

The trip that brings it home

Outbreaks flare in different countries at different times, and a plane is how measles crosses a border. Before an overseas trip, especially somewhere with a known outbreak:

Confirm your child’s MMR is complete for their age.
Ask your doctor about an early dose for a baby aged 6 to 11 months heading to a high-risk area. The routine doses still follow at 12 and 15 to 18 months.
Check your own status. An adult who never had two doses or the illness can catch and carry it.
Watch for symptoms for up to three weeks after you return, and tell the clinic you have travelled.

If measles gets in anyway

See a doctor, and phone ahead so the clinic can keep an infectious child away from babies and pregnant women in the waiting room. There is no cure, so care is rest, fluids and fever control, with hospital treatment if complications set in. Keep the child home and apart from others until a doctor says the all-clear, because measles is contagious before the rash even shows. It is a notifiable disease, so the doctor reports it.

Common questions

When is the MMR vaccine given in Singapore?

The first dose at 12 months and the second at 15 to 18 months, under the National Childhood Immunisation Schedule. Two doses give strong protection, and it’s free for Singaporean children.

Is the measles vaccine compulsory in Singapore?

Yes. Immunisation against measles is required by law under the Infectious Diseases Act, and children who miss doses are vaccinated in Primary 1.

What are the symptoms of measles?

High fever, cough, runny nose and red eyes, tiny white spots inside the cheeks, and a blotchy red rash that starts on the face and spreads down the body a few days later.

Can my baby get the MMR vaccine early for travel?

Yes. A dose can be given from 6 to 11 months for a baby travelling to a high-risk area, with the routine doses still following at 12 and 15 to 18 months. Ask your doctor.

Is the MMR vaccine safe?

Yes. It’s safe and well studied. The claim linking it to autism came from a retracted, discredited study and has been disproven. Measles itself is the real danger.

How dangerous is measles?

It can cause ear infections, pneumonia and, rarely, brain inflammation that can be fatal. It’s most dangerous for babies too young to be vaccinated and for unvaccinated children.

Keeping your child covered

Two doses of MMR, at 12 months and 15 to 18 months, are the beginning and end of measles protection, and in Singapore they are free and required. The only homework is to check your child is current, most easily before a trip abroad, and to ask about an early dose if you’re taking a young baby somewhere measles is circulating.
