Vaccines for your child

Vaccinating or immunising your baby may protect them from serious or even fatal diseases. Read a list of vaccines for your child and when they should get them.

Vaccinating or immunising your baby may protect them from some serious or even fatal diseases.

How vaccines work

Vaccination is a safe and effective way to protect your baby against certain diseases. These diseases can cause serious illness or even death.

When your child gets a vaccine, their body responds by making antibodies. It's as if they had caught the disease, but without getting sick.

Their body then produces antibodies to destroy the vaccine. These stay in your child's body and protect them against the actual disease.

Vaccine safety

As a parent, you might not like the fact that your baby has to get an injection.

But remember, vaccinations:

  • are quick, safe and effective
  • protect your baby from disease
  • help your baby to fight diseases

If you don't vaccinate your child, there is a chance they could become very ill, or even die.

Be ready with a feed or a hug for your baby and the vaccination will be forgotten soon afterwards.

Vaccines your child will get

At 2 months

  • PCV (pneumococcal conjugate vaccine)
  • MenB vaccine (meningococcal B vaccine)
  • Rotavirus oral vaccine
  • 6-in-1 vaccine

6-in-1 vaccine

The 6-in-1 vaccine is a 3 dose vaccine and protects babies against 6 different diseases:

  1. Diphtheria
  2. Tetanus
  3. Whooping cough (pertussis)
  4. Hib (Haemophilus influenzae b)
  5. Polio (inactivated poliomyelitis)
  6. Hepatitis B

At 4 months

  • 6-in-1 vaccine
  • MenB vaccine (meningococcal B vaccine)
  • Rotavirus oral vaccine

At 6 months

  • 6-in-1 vaccine
  • PCV (pneumococcal conjugate vaccine)
  • MenC vaccine (meningococcal C vaccine)

At 12 months

  • MMR (measles, mumps and rubella)
  • MenB vaccine (meningococcal B vaccine)

At 13 months

  • Hib/MenC (Haemophilus influenzae b and meningococcal C combined vaccine)
  • PCV (pneumococcal conjugate vaccine)

If your baby gets sick after a vaccine

Common side effects after vaccination are redness, soreness or swelling where your baby got their injection. Your baby might also become irritable. Fever is a common side effect after MenB vaccination at 2 and 4 months and liquid infant paracetamol is recommended.

If your child is very unwell after vaccination, there may be some other reason for the sickness. Talk to your GP about this.

How often you need to visit the GP

Your child needs 5 visits to your GP between 2 to 13 months to complete their course of vaccinations. This will fully protect them against serious illnesses.

How long vaccines take to work

It usually takes a few weeks for vaccines to work. Your child will not be protected immediately.

Also, most vaccines need to be given several times to build up long-lasting protection. For example, a child who gets only 1 or 2 doses of the whooping cough vaccine is only partly protected. They may still catch whooping cough if the course is not completed.

Why your child needs more than one dose of a vaccine

More than 1 dose of the same vaccine is given in the first few years of a child's life. The extra doses improve the antibody response and give better long-term protection.

Booster doses of some vaccines are also given to school children to give better long-term protection.
