The Chickenpox vaccine is a safe and effective way to protect against the varicella-zoster virus, which causes chickenpox. This highly contagious illness can lead to an itchy rash, fever, and fatigue, and in some cases, serious complications such as pneumonia, skin infections, or brain inflammation. The vaccine, typically administered in two doses, helps your body develop immunity, significantly reducing the risk of contracting chickenpox and minimizing the severity of symptoms if exposed.
Getting vaccinated is not only important for personal health but also for the health of the community. The Chickenpox vaccine reduces the spread of the virus, protecting vulnerable individuals such as infants, pregnant women, and those with weakened immune systems who cannot be vaccinated. By choosing vaccination, you contribute to building herd immunity, ensuring that everyone is better protected from this preventable disease.

Chickenpox is a highly contagious virus caused by the varicella-zoster virus, The chickenpox vaccine is usually administered in childhood however, adults who never received the vaccine are at risk for getting chickenpox later in life as well as shingles, including a painful shingles rash and nerve pain. The chickenpox vaccine is recommended for both adults and children because it provides safe, effective protection against both chickenpox and shingles, safeguarding health and preventing the spread of this highly transmissible virus.
The chickenpox vaccine is recommended for:
Children: Provided in two doses typically at 12-15 months and 4-6 years.
Unvaccinated Teens and Adults: Especially important if they have never had chickenpox before.
High-Risk Workers: These include healthcare, childcare, and school workers to prevent virus spread.
People with Specific Health Conditions: For those with chronic conditions or weakened immune systems (if eligible).
Pregnant women and immunocompromised people should consult a healthcare provider before vaccination.
The chickenpox vaccine works by introducing a weakened form of the varicella-zoster virus, the virus responsible for chickenpox, into the body. This modified virus stimulates the immune system to recognize and defend against the virus without causing the actual disease. Once vaccinated, the immune system builds up antibodies specifically designed to fight the chickenpox virus, providing long-term protection.
The vaccine is highly effective, with two doses offering over 90% immunity against chickenpox. In cases where those vaccinated do contract chickenpox, the illness is typically much milder, with fewer blisters and quicker recovery. The vaccine lowers the likelihood of the virus reactivating later in life as shingles, adding an extra layer of protection. For adults who haven’t had chickenpox or who are unsure of their immunity, the chickenpox vaccine is a safe, reliable way to prevent this contagious and potentially serious illness.

Adults need the chickenpox vaccine because, while chickenpox is often mild in children, it can lead to more serious complications in adults. When contracted later in life, chickenpox can result in severe symptoms, including high fevers, bacterial infections, pneumonia, and, in rare cases, life-threatening conditions. The varicella-zoster virus can reactivate later in life, leading to a painful shingles rash with potential long-term nerve pain known as postherpetic neuralgia.
Vaccination significantly reduces these risks by providing chickenpox immunity without experiencing the illness. For adults who haven’t had chickenpox or been vaccinated, the chickenpox vaccine is a safe, effective way to avoid the virus and its complications. It’s important for those with weakened immune systems or those who work in environments where they could transmit the virus to others, like healthcare and childcare.
Benefits of the Chickenpox Vaccine for Adults
The chickenpox virus vaccine provides these benefits for adults:
Prevents severe illness: Reduces severe symptoms and complications, more common in adults, like pneumonia and encephalitis.
Reduces shingles risk: Lowers the chance that varicella-zoster virus will reactivate as shingles later in life.
Protects vulnerable populations: Prevents spread of the virus to children, the elderly, and immunocompromised people who may experience more severe outcomes.
Minimizes work and life disruptions: Avoids disruptions and missed workdays caused by illness or quarantine.
Safe and effective immunity: Provides immunity without the risks associated with contracting the illness.
Understanding the Risks of Chickenpox in Adulthood
Chickenpox in adulthood carries higher risks than in childhood, often leading to severe symptoms and complications. Adults who contract chickenpox are more likely to experience intense fevers, severe rashes, and secondary infections, like bacterial skin infections or pneumonia. There is also a risk of life-threatening complications, including encephalitis, inflammation of the brain, or blood clotting issues. Adults infected with the varicella-zoster virus face an increased chance of developing a painful reactivation of the shingles virus that can lead to long-term nerve pain. Given these heightened risks, adults are encouraged to consider vaccination to protect themselves and reduce their risk of suffering from serious health consequences.
Can Chickenpox Reoccur in Adults?
Chickenpox itself does not usually reoccur in adults, because the body builds lifelong immunity after the initial infection or vaccination. However, the varicella-zoster virus, which causes chickenpox, can remain dormant in the body’s nerve tissues and reactivate later in life as shingles. Adults who have had chickenpox can reduce their risk of shingles with the shingles vaccine, which prevents reactivation of the varicella-zoster virus.
Adults 50 years of age and older are eligible for the shingles vaccine, regardless of whether they previously experienced shingles. Adults with compromised immune systems, such as those receiving chemotherapy or on immunosuppressive drugs, might potentially qualify, but should first speak with their doctor to find out if the vaccination is suitable for them. To find out if you qualify, speak with your doctor about your medical history.

Steps to Stay Protected Against Chickenpox
To stay protected against chickenpox, consider the following steps:
Get Vaccinated: The chickenpox vaccine is the most effective way to prevent infection. It’s recommended for children and adults who haven’t had chickenpox or been vaccinated.
Know Your Immunity Status: If you’re unsure whether you had chickenpox or received the vaccine, a healthcare team member at Portland Urgent Care can perform a blood test to check you for immunity.
Practice Good Hygiene: Regular hand washing and avoiding close contact with those infected can reduce the risk of transmission.
Consider the Shingles Vaccine: If you've had chickenpox, the shingles vaccine can help prevent the virus from reactivating later in life as shingles.
Limit Exposure in High-Risk Situations: In crowded environments or healthcare settings, take precautions if there are known cases of chickenpox.
Following these steps can help protect you from chickenpox and reduce the chances of complications associated with the varicella-zoster virus.
