1. What is chickenpox?

Chickenpox or chickenpox is a highly contagious disease caused by varicella-zoster virus (VZV). The disease can be encountered at any age, especially children, in winter – spring. When infected with the virus, the incubation period is from 10-14 days before the ons of the one. It causes blister-like rashes, itching, fatigue and fever. Chickenpox can be serious especially in babies, adults and those with poor immune systems.

It spreads easily from an infected person to another person who has never had chickenpox or has never been vaccinated against chickenpox. When a person carrying chickenpox virus speaks, sneezes with a runny nose or coughs… then the viruses follow the saliva, the nasal water that shoots out dissolves into dust and others inhale those particles of dust will immediately spread the disease. Besides, the virus is capable of living for several days in chickenpox scales when peeling off and persisting in the air, so the disease can also spread from the outbreak of chickenpox nodules. On the other hand, the disease can also be transmitted through indirect contact with objects and living tools that are infected with the pathogenic virus. Another route of transmission is from the mother transmitted to the fetus through the placenta or at birth. Therefore, the effective measure of prevention of chickenpox is the vaccination of chickenpox vaccination.

2. Side effects of chickenpox vaccination

Chickenpox vaccine is very safe and effective against chickenpox most optimal in current preventive methods. This vaccine, like other drugs, also has side effects when used. Most people vaccinated with chickenpox do not have any problems with the dose of the vaccine. This vaccine is usually given in two doses. Side effects that appear after the first injection dose are higher than the second dose.

The most common side effects of chickenpox vaccine:

  • Muscle aches and redness, bruising, swelling around the injection site – this side effect occurs only in about 1 in 5 children and 1 in 4 adolescents or adults.
  • Fever, a mild rash on the skin that looks like chickenpox but less redness, can occur about 2 weeks after injection.
  • Rash – occurs only in about 1 in 10 children and 1 in 20 adults.
  • Runny nose or nasal congestion, cough, sore throat, headache, nausea.
  • Feeling tired, may suffer from insomnia.
  • Stomach pain or possible diarrhea.

After vaccination with chickenpox, the body often appears fever and has additional common side effects. Dangerous side effects may appear but these cases are extremely rare. A small number of cases reported after chickenpox vaccination include severe rashes, lung or liver infections, meningitis, convulsions, pneumonia, or more severe infection with the strain of the virus from the vaccine.

Serious side effects of chickenpox vaccines such as allergic reactions(anaphylactic shock)are also rare. This reaction occurs only in about 1 in 1 million vaccinated people. Some children have these serious side effects after vaccination that have weakened the immune system before vaccination, but they have not been diagnosed by a doctor at the time of vaccination.

People who are vaccinated with chickenpox can transmit varicella-zoster virus to others. However, this is also extremely rare.

Pregnant women, those who are moderately or severely ill at the time of vaccination are scheduled, and those who are allergic to any component of the vaccine should not be vaccinated against chickenpox.

3. The problem of chickenpox vaccination in children

All children from 12 months of age should be prevented with two doses of chickenpox vaccine. Chickenpox vaccination is not recommended for children under 12 months of age even with post-exposure prophylaxization.

The Centers for Disease Control and Prevention (CDC) recommends that a healthy infant (that is, not immunosuppressed, so it is not necessary to be a sick person taking chickenpox-immune globulin (VZIG)), should not be specifically treated or vaccinated after exposure to chickenpox virus. Children can be treated with acyclovir if chickenpox occurs.

Chickenpox vaccination for children is up to 97% preventable. For children from 12 months to 12 years: the first injection at 12 months, the second injection is about 4-6 years old. For children over 13 years of age two injections and the second from the first from 4-8 weeks.

The chickenpox vaccine after being introduced into the body takes 1-2 weeks to come into play. In Vietnam, chickenpox season usually occurs in February-June every year. Therefore, parents should take their children for chickenpox vaccination at least 1 month before the epidemic season.
