Molecule Description
Varicella Vaccine Live Attenuated is a live attenuated vaccine used to prevent chickenpox (varicella) in individuals aged 12 months and older. It contains a weakened form of the varicella-zoster virus, which helps the immune system recognize and build protection against the actual virus without causing the disease. This vaccine does not treat an active chickenpox infection but is used to prevent future infections. It is administered by a healthcare professional and should never be self-administered.
The vaccine works by stimulating the body's immune response to produce antibodies against the varicella virus. These antibodies remain in the system and help prevent infection if the person is exposed to the virus later in life. It is essential to follow any post-vaccination care instructions provided by the healthcare provider.
Before receiving Varicella Vaccine Live Attenuated, it is important to inform the doctor about any existing medical conditions, such as kidney or liver disease, or a history of organ transplantation. Salicylates, such as aspirin, should not be taken for six weeks following vaccination due to a potential association with Reye syndrome. Individuals who are in close contact with people who are immunocompromised, pregnant without a history of chickenpox, or newborns born before 28 weeks gestation should also take precautions. If a rash develops after vaccination, medical advice should be sought promptly.
The vaccine should be stored at a temperature between 2°C to 8°C and protected from light. It must be kept out of the reach of children and properly disposed of by healthcare professionals.

Mode of Action
How Does It Work?
Varicella Vaccine Live Attenuated, commonly known as the chickenpox vaccine, is an injection that contains a weakened form of the chickenpox virus. It helps your body's immune system learn to fight off the actual chickenpox virus if you come into contact with it. Varicella Vaccine Live Attenuated does not treat an active chickenpox infection.
Interactions
Interactions with other medicines
- Do not take aspirin or salicylates for 6 weeks after receiving the vaccine, as this helps prevent the risk of Reye's syndrome.
- Inform your doctor if you have recently received immune globulins or blood products, as these may reduce the vaccine's effectiveness.
- If you need a TB (PPD) skin test, schedule it before, on the same day, or 4 weeks after Varicella Vaccine Live Attenuated to avoid false test results.
- Varicella Vaccine Live Attenuated can be administered with other live vaccines. If not given together, wait 1 month after a measles-containing vaccine before receiving Varicella Vaccine Live Attenuated. For spacing between chickenpox vaccines: Children (12 years and under) should wait at least 3 months between doses, while teens and adults can receive the second dose 1 month after the first.
- You can take Varicella Vaccine Live Attenuated at the same time as M-M-R II (Measles, Mumps, Rubella), Hib vaccine (Haemophilus influenzae type b), and Hepatitis B (recombinant) vaccine.
- Discuss with your doctor any other medicine, herbal preparation and supplements you are taking currently to avoid any possible drug interactions.
