Varicella (live Attenuated)
About Varicella (live Attenuated)
Varicella (live Attenuated) is an injectable vaccine used to help prevent chickenpox (varicella) in children, adolescents, and adults who are not already immune. It contains a live but weakened form of the varicella-zoster virus that helps your body develop protection against future infection. By preventing chickenpox, Varicella (live Attenuated) also helps reduce the spread of the virus and lowers the risk of serious complications associated with the disease.
Varicella (live Attenuated) is not taken every day. It is given according to a recommended one-dose or two-dose vaccination schedule based on your age, health condition, and previous vaccination history. It may be administered with or without regard to meals because food does not affect how Varicella (live Attenuated) works. Eating a balanced diet, drinking enough fluids, and getting adequate rest may help support your body's normal immune response after vaccination.
Most people receive Varicella (live Attenuated) without any serious problems. Mild side effects such as pain, redness, swelling at the injection site, mild fever, or a small rash may occur and usually resolve within a few days. Serious allergic reactions are very rare, but if you develop difficulty breathing, swelling of the face or throat, a widespread rash, or a high fever after vaccination, seek immediate medical attention. As a routine safety measure, your healthcare provider may ask you to remain at the vaccination center for about 15 to 30 minutes after the injection to monitor for any immediate allergic reactions.
Before receiving Varicella (live Attenuated), tell your doctor if you have a weakened immune system, cancer, untreated tuberculosis, or are taking medicines that suppress your immune system. Do not receive Varicella (live Attenuated) if you have had a severe allergic reaction to gelatin, neomycin, or a previous dose of Varicella (live Attenuated). Vaccination should also be postponed if you have a moderate or severe illness with fever until you have recovered.
Certain medicines and blood products can reduce the effectiveness of Varicella (live Attenuated). Aspirin and aspirin-containing medicines should generally be avoided for several weeks after vaccination because of the rare risk of Reye's syndrome, a serious condition affecting the brain and liver. If you have recently received blood transfusions or immune globulin treatment, your doctor may recommend delaying vaccination. Varicella (live Attenuated) is not recommended during pregnancy, and women should avoid becoming pregnant for the recommended period after vaccination as advised by their healthcare provider. Breastfeeding mothers can generally receive Varicella (live Attenuated), but they should discuss their individual circumstances with their doctor before vaccination.
Uses of Varicella (live Attenuated)
• Prevention of Chickenpox: Varicella (live Attenuated) is primarily used to protect against chickenpox, a highly contagious viral infection characterized by an itchy rash and flu-like symptoms.
• Boosting Immune Response: Varicella (live Attenuated) helps in stimulating the body's immune system to produce antibodies that can effectively fight off the varicella-zoster virus.
• Reducing Severity of Illness: For those who do contract chickenpox after vaccination, studies indicate that the symptoms tend to be milder and the duration of the illness is often shorter.

- Remain under observation after vaccination: Stay at the vaccination clinic for 15 to 30 minutes after receiving the injection so your healthcare provider can monitor you for any immediate allergic reactions.
- Keep a record of your vaccinations: Maintain a written or digital record of your vaccination dates to help ensure all recommended doses are received on schedule.
- Avoid close contact if a vaccine-related rash develops: If you develop a mild rash after vaccination, avoid close contact with pregnant women, newborn babies, and people with severely weakened immune systems until your doctor advises it is safe.
- Inform your doctor about recent treatments or vaccinations: Tell your healthcare provider if you have recently received another live vaccine, a blood transfusion, or immune globulin treatment, as these may affect when Varicella (live Attenuated) should be given or how well it works.
- Avoid aspirin after vaccination: Do not take aspirin or aspirin-containing medicines for at least 6 weeks after vaccination unless specifically instructed by your doctor.
- Discuss immune system conditions before vaccination: Inform your healthcare provider if you have a weakened immune system or are receiving chemotherapy, high-dose steroids, or other medicines that suppress immunity before receiving Varicella (live Attenuated).
- Understand the purpose of Varicella (live Attenuated): Varicella (live Attenuated) helps protect against chickenpox and its complications. Although the virus can remain inactive in the body and reactivate later in life as shingles, vaccination helps reduce the risk of chickenpox.
Drug Interactions
- Aspirin and aspirin-containing medicines: Avoid these medicines for at least six weeks after receiving Varicella (live Attenuated), as they may increase the risk of Reye's syndrome, a rare condition that affects the brain and liver.
- Immunosuppressive medicines (e.g., chemotherapy medicines, high-dose steroids): These medicines may reduce your body's immune response and make Varicella (live Attenuated) less effective.
- Other live vaccines: If not given on the same day, other live vaccines are usually administered at least four weeks apart to ensure the best immune response.
- Immune globulins or blood transfusions: These blood products may reduce the effectiveness of Varicella (live Attenuated). Your doctor may recommend delaying vaccination depending on the type and timing of the blood product received.

Patients Concern
Disease/Condition Glossary
Chickenpox: The varicella-zoster virus causes a vaccine-preventable viral infection. It is extremely contagious, especially among people who have never had the disease or have not been immunised against it. Although it is most commonly seen in children, adults can contract this infection. Rashes, small painful blisters, fever, sore throat, and body pain are all common symptoms. This disease is treated with antiviral medications. Avoid contact with other people who have chickenpox and practise good hygiene to recover quickly.
FAQs
Varicella (live Attenuated) is used to prevent varicella or chickenpox.
Varicella (live Attenuated) is an immunizing agent or vaccine from a live, weakened, or attenuated varicella-zoster virus. It helps to provide persistent or long-lasting protection against varicella or chickenpox by stimulating the immune system to form antibodies.
Your doctor will determine the number of doses required based on age, vaccine history and health condition. You must inform your doctor if you have taken any vaccines before taking Varicella (live Attenuated).
Taking aspirin, aspirin-containing drugs, or any other salicylates for at least six weeks after taking Varicella (live Attenuated) is not recommended as it may cause Reye's syndrome, a severe condition resulting in liver and brain damage.
Varicella (live Attenuated) may cause side effects such as fever, pain, swelling, and redness at the injection site. These side effects are usually mild and temporary. However, if any of these side effects persist or get worse, inform your doctor immediately.
Varicella (live Attenuated) is not recommended for use in children below nine months of age, pregnant women, people with a weak immune system (such as people with HIV, cancer, or people taking high doses of corticosteroids or immune suppressants), people with active and untreated tuberculosis, and people who have a temperature higher than 38.5°C.
No. Varicella (live Attenuated) is generally not recommended during pregnancy because it contains a live, weakened virus. If you are planning a pregnancy, discuss vaccination with your doctor beforehand. If you receive Varicella (live Attenuated), your doctor will advise you on how long to avoid becoming pregnant based on current vaccination recommendations.
Most children receive two doses, with the first dose usually given at 12 to 15 months of age and the second dose at 4 to 6 years. Adolescents and adults who are not immune also generally require two doses, usually given 4 to 8 weeks apart according to your healthcare provider's recommendation.
Varicella (live Attenuated) contains a weakened form of the virus, so it does not usually cause chickenpox in healthy people. Some individuals may develop a small, mild rash after vaccination, but this is generally much milder than natural chickenpox and usually resolves on its own.
Breastfeeding is generally not considered a reason to avoid Varicella (live Attenuated), and many breastfeeding mothers can safely receive it. Although the risk to the infant is considered very low, discuss your individual situation with your healthcare provider before vaccination.
Completing the recommended vaccination schedule provides long-lasting protection for most people. The duration of immunity varies between individuals, but protection generally lasts for many years and significantly reduces the risk of severe chickenpox.
A mild rash can occur in a small number of people after vaccination. Keep the affected area clean, avoid scratching, and follow your healthcare provider's advice. If the rash becomes severe, spreads extensively, or is accompanied by a high fever, seek medical attention.
Routine use of fever-reducing medicines before vaccination is generally not recommended unless advised by your healthcare provider. However, paracetamol may be used afterward if needed to manage fever or discomfort following vaccination.
There is no fixed upper age limit. Adults who have never had chickenpox and are not immune may still benefit from vaccination if they have no medical conditions that prevent them from receiving a live vaccine. Your healthcare provider can determine whether Varicella (live Attenuated) is appropriate for you.
Most people who have had chickenpox develop long-lasting immunity and usually do not need vaccination. If you are unsure whether you have had chickenpox or whether you are immune, your healthcare provider may recommend testing or advise you on whether vaccination is appropriate.
Yes. If given within 3 to 5 days after exposure, Varicella (live Attenuated) may help prevent chickenpox or reduce the severity of the illness in eligible individuals. Contact your healthcare provider as soon as possible after exposure for advice.
