Chickenpox Vaccine For Adults

While many associate chickenpox with childhood, the reality is adults can also contract this contagious viral infection. As an adult, contracting chickenpox can lead to serious health implications.

This is why the chickenpox vaccine for adults is essential, especially for those who never had the infection during their childhood.

What Causes Chickenpox

Before diving into the specifics of the vaccine, it’s important to understand what chickenpox is.

Chickenpox, caused by the varicella-zoster virus, is a highly infectious disease known for causing an itchy rash and red spots or blisters all over the body. It can also lead to severe complications in adults, including pneumonia, brain inflammation, and skin infections.

The Necessity of Chickenpox Vaccine for Adults

If you’ve never had chickenpox and have not been vaccinated, you are at risk of catching the disease.

Adults who get chickenpox are more likely to experience severe symptoms compared to children. It’s why the chickenpox vaccine is not just for kids but a critical preventive measure for adults too.

Efficacy and Schedule of Chickenpox Vaccine

The chickenpox vaccine, also known as the varicella vaccine, is highly effective in preventing infection.

For adults, the vaccine is usually given in two doses, four to eight weeks apart. The vaccine can prevent the disease entirely or significantly lessen the severity if one does contract chickenpox.

Adults Who Should Get the Chickenpox Vaccine

While the vaccine is generally recommended for all adults who have never had chickenpox, there are specific groups who should seriously consider getting vaccinated:

Healthcare Workers and Teachers

Due to their constant exposure to various individuals, including those who might be infected, these professionals are at a higher risk of contracting chickenpox.

Non-immune Adults Living with Young Children

Young children, especially those in daycare or school, are more likely to contract chickenpox. Adults living with young children should consider the vaccine to avoid catching the virus.


If you’re travelling to locations where chickenpox is common, the vaccine is a wise precautionary measure.

Adults Who Should Not Get the Chickenpox Vaccine

Although the chickenpox vaccine is beneficial for most adults, there are specific groups who should avoid it:

  • Pregnant women or those planning to get pregnant within the next month should avoid the chickenpox vaccine.
  • Individuals with a weakened immune system due to diseases like HIV/AIDS or treatments like chemotherapy should consult their doctor before getting the vaccine.
  • Any adult who has had a life-threatening allergic reaction to a previous dose of the chickenpox vaccine or any of its ingredients should refrain from getting the vaccine.

Chickenpox Vaccine Side Effects and Protection For Adults

The chickenpox vaccine is generally safe with minor side effects such as soreness at the injection site, mild fever, or a rash.

Protection from the virus develops within four to six weeks after vaccination, with the second dose strengthening the immune response.

The Science Behind the Chickenpox Vaccine

Understanding how the chickenpox vaccine works can provide further insight into its importance for adults.

The varicella vaccine contains a weakened form of the varicella-zoster virus that stimulates your immune system to produce antibodies.

These antibodies will then fight off the virus inside your adult body if you are exposed to it in the future. As a result, you either won’t get chickenpox or if you do, the symptoms will be much milder.

Significance of Chickenpox Vaccine For Herd Immunity In Adults

When you get vaccinated, you are not only protecting yourself but also contributing to herd immunity.

This form of indirect protection occurs when a large part of the population is vaccinated, reducing the overall amount of virus able to spread in the community.

For adults, especially those in contact with people with weak or compromised immune systems, getting the chickenpox vaccine is a significant contribution to this communal safeguarding effort.

Embrace Prevention with the Adults Chickenpox Vaccine

Getting the chickenpox vaccine as an adult is a proactive step towards preventing potential health complications.

Your Health Your Choice

If you’re unsure about whether you need the vaccine, consult with a healthcare professional. They can provide personalized advice based on your health history and lifestyle.

Remember, prevention is always better than cure, and the chickenpox vaccine for adults is a testament to this maxim.
