What is varicella?

Chickenpox or Varicella is a viral infection caused by a virus called varicella-zoster. This infection causes itchy rashes that appear as blisters on the skin. This disease can be spread by sneezing or coughing or direct contact without the vaccine. You could also get it by contact with fluid from chickenpox blisters.
The disease is highly contagious, and people who have not been infected or who have not been vaccinated are at risk.
Symptoms of chickenpox include:
● Itchy blister rash that appears 10 to 21 days after exposure to the virus and lasts for 5 to 10 days.
● Fever
● Decreased appetite
● Headache
● Weakness

In severe cases, the rash may cover the entire face. Lesions may also occur in the throat, eyes, and mucous membranes of the uterus, anus, and vagina. Chickenpox is often a mild infection but can cause the following complication:
● Dehydration
● Pneumonia
● Inflammation of the brain
● Toxic shock syndrome
● Ray syndrome
● Bacterial infections of the skin, bones, soft tissues, joints, and bloodstream
● Death
● shingles

People with chickenpox are at risk for a complication called shingles. In some cases, the varicella-zoster virus remains in the nerve cells. Many years later, the virus reactivates and leads to painful blisters. Shingles is common in people with weakened immune systems and elderly people. In some cases, chronic pain persists even after the blisters have been disappeared.

What is the varicella vaccine?

The varicella vaccine contains an active immunizing agent that causes the body to make a protein called an antibody against the varicella-zoster virus. In this way, long-term immunity is achieved. You will be immune to this virus if you receive two doses of the vaccine or your doctor determines that you have had chickenpox before.
The varicella vaccine is available as a Powder for Suspension and is given by a nurse or other trained health professional as a subcutaneous shot in the upper arms or front of your thighs.

– The first dose is injected at 12 to 15 months
– The second dose of varicella vaccine is injected at the age of 4 to 6 years
The second dose of the vaccine can be used earlier but must be at least three months after the first dose.
● People over 13 years of age who have never had varicella before and have not been vaccinated
– These people also need two doses of varicella vaccine, but the interval between two injections should be at least 28 days
