Chickenpox is a disease that we usually get through in childhood. The disease is not very serious, but vaccination against smallpox should be considered due to possible complications. In Poland, smallpox vaccination is on the list of recommended vaccinations. When can you get vaccinated? What is worth remembering?

Chickenpox is a disease that children often have in preschool age. Its course is usually mild, but you never know who will develop serious complications. That’s why doctors recommend parents get vaccinated for smallpox. Unfortunately, complications after smallpox require hospitalization and can be dangerous even for our lives.

Smallpox vaccination – disease characteristics

Chickenpox is an infectious disease. It is caused by the smallpox and shingles virus. Smallpox is very contagious and affects almost everyone who comes into contact with it. Although the disease most often affects children in preschool age, there are cases of the disease in older children and even adults who were not sick in childhood.

Smallpox is usually mild, but the complications have more serious consequences for your health. These are:

  1. bacterial infections of the skin and soft tissues;
  2. encephalitis;
  3. neurological complications;
  4. pneumonia.

The course of smallpox and the risk of complications is much higher in adolescents and adults. Smallpox is also dangerous for pregnant women, newborns and immunocompromised people. Therefore, it is worth considering a smallpox vaccination.

Smallpox vaccination – disease risk

Smallpox is very easy to get infected, which is why most people who have had smallpox have had it before the age of 9. The sick person infects others 1-2 days before the appearance of the rash until the bubbles disappear. A person with scabs is not contagious.

Smallpox vaccination – disease prevention

Vaccination is the only solution if we want to avoid this common disease. Vaccination against smallpox gives lasting protection. The vaccine available in Poland contains a live virus that does not cause disease in healthy children. Its task is to support immunity.

The vaccine is an effective form of protection against smallpox. Smallpox cases after vaccination are rare, and if it does occur, smallpox is mild. If your child has not had smallpox and has not been vaccinated, and has been in contact with a smallpox patient, the child may be vaccinated within 72 hours of the possible infection. Even if a child becomes ill, smallpox is milder.
