What is Chickenpox?

Chickenpox is a highly contagious viral infection caused by the varicella-zoster virus. It primarily affects children but can also occur in adults who have not had the disease or been vaccinated. The infection is characterized by a red, itchy rash that progresses into fluid-filled blisters, which eventually scab over. Other symptoms may include fever, fatigue, loss of appetite, and headaches. 

Chickenpox spreads easily through direct contact with the blisters or through the air when an infected person coughs or sneezes. While the infection is usually mild in children, it can be more severe in adults or people with weakened immune systems. There is a vaccine available to prevent chickenpox, which has significantly reduced the number of cases.

Chickenpox is prevalent worldwide, but its occurrence tends to vary based on vaccination rates and public health measures. The virus is common in developed countries although with wider vaccination and better public health the virus is becoming increasingly less common.

How to prevent Chickenpox?

There are many ways to prevent chickenpox such as; vaccination, herd immunity and avoiding contact. Vaccination is the most effective way to prevent the virus. The vaccination is typically given in two doses, one at age 6-12 months and one at ages 4-6. If you are an adult who has not had the virus or been vaccinated it is highly recommended you are. Herd immunity is when a large portion of the population is vaccinated therefore minimising the spread. This proves how vital vaccination is in keeping everyone safe. Another good way of prevention is to avoid contact with someone with the virus or if you have it yourself, minimize your own contact with others.

Are there side effects of the chickenpox vaccine?

Yes in general the vaccination is considered safe however there are some common side effects such as; fever, redness or pain at the injection site or a rash. Some rarer side effects are severe allergic reactions and blisters. In some rare cases, patients may develop the virus itself after taking the vaccine.

If you experience these or any other side effects after taking the vaccine you should report it to your GP even if you are not certain that the vaccine caused it.
