One week ago I took my daughter to get her one year vaccinations, I decided to film the process to show new parents what to expect.
After vaccination with MMR
The three viruses in the vaccine act at different times and may produce the following side effects after the first dose.
Six to 10 days after the immunisation, as the measles part of the vaccine starts to work, about one in 10 children may develop a fever and some develop a measleslike rash and go off their food (for advice on treating a fever, see page 11).
About one in every 1000 immunised children may have a fit caused by a fever. This is called a ‘febrile convulsion’ (see page 14). However, if a child who has not been immunised gets measles, they are five times more likely to have a fit.
Rarely, children may get mumpslike symptoms (fever and swollen glands) about three weeks after their immunisation as the mumps part of the vaccine starts to work.
Very rarely, children may get a rash of small bruiselike spots in the six weeks after the vaccination. This is usually caused by the measles or rubella parts of the vaccine. If you see spots like these, take your child to the doctor to be checked. He or she will tell you how to deal with the rash.
Fewer than one child in a million develops encephalitis (swelling of the brain) after the MMR vaccine, and there is very little evidence that it is actually caused by the vaccine. However, if a child who has not been vaccinated catches measles, the chance of developing encephalitis is between one in 200 and one in 5000.
After immunisation with the PCV booster
Out of 10 babies immunised, one or two may get swelling, redness or tenderness where they had the injection, or they may have a mild fever.
