How vaccines work

You should know that vaccines teach your immune system how to create antibodies that protect you from diseases. It is much safe for your immune system to learn through vaccinations than by catching the diseases and treating them.

When your immune system knows how to fight against diseases, it can protect you for many years. Also, having a vaccine can benefit your whole community through “herd immunity”. If more people are vaccinated, then it is harder for this disease to spread to people who cannot have vaccines, such as people who are ill or people who have a weakened immune system. All vaccines are thoroughly tested to make sure that they will not harm you or your children. In many cases, it takes many years for a vaccine to make it through the trials and tests and it needs to pass for approval.

Side effects of vaccination

In most cases, the side effects of vaccines are mild and they do not last long. The most common side effects of vaccinations include:

  • Babies or young children can feel a bit unwell or develop a high temperature (fever) for one or two days
  • The area where the needle goes in looking red, swollen and feeling a bit sore for two to three days

Also, some children may cry and be upset immediately after the injection. This is normal and they should feel better after a cuddle. It is a rare case to have a serious allergic reaction to a vaccination. If this happens, then it usually happens in a period of few minutes. The person who is vaccinating you or your children is trained to deal with allergic reactions and treat them immediately. When you have a prompt treatment, then you or your child will make a good recovery. You should speak with your doctor if you are worried about you or child having a vaccine.
