Shingles is a painful skin rash caused by the varicella-zoster virus — the same virus that causes chickenpox. Many people in the UK choose to get vaccinated against shingles, especially as they get older. However, a common concern is whether someone can be contagious after the shingles vaccine or even experience a shingles outbreak after the vaccine. Let’s explore this in simple terms.
What Does the Shingles Vaccine Do?
There are two main types of shingles vaccines in the UK — Zostavax (a live vaccine) and Shingrix (a non-live vaccine). These are given to reduce your risk of developing shingles and to lessen the severity if you do get it.
- Zostavax contains a weakened form of the virus.
- Shingrix does not contain live virus, so it cannot cause infection.
Can You Catch Shingles After Vaccination?
Yes, but it’s very rare. No vaccine offers 100% protection. However, if you do get shingles after being vaccinated, the symptoms are usually much milder and the risk of complications is lower.
So, while you can catch shingles after vaccination, the vaccine still offers strong protection, especially for people over 70.
Can You Spread Shingles After the Vaccine?
This depends on the type of vaccine and your condition after getting it.
- With Zostavax (live vaccine): There is a very small chance that you might pass on the virus to someone else — but only if a rash develops at the injection site. Even then, the virus could only be passed on through direct contact with the rash.
It’s extremely rare, and even if the virus is passed, it could cause chickenpox in someone who has never had it — not shingles. - With Shingrix (non-live vaccine): You cannot pass on the virus to anyone because the vaccine does not contain live virus. There is no shingles vaccine transmission risk with this option.
So, unless you develop a rash after a live vaccine and someone touches it directly, the risk of spreading shingles or chickenpox is practically zero.
Shingles Vaccine Side Effects: What to Expect
Most people tolerate the shingles vaccine well. You may experience:
- Redness, soreness, or swelling where the injection was given
- Headache
- Tiredness
- Mild fever
These shingles vaccine side effects are usually short-lived and a sign that your body is building protection.
Is Chickenpox Contagious After the Shingles Vaccine?
No, the vaccine does not make chickenpox contagious. However, shingles itself comes from the same virus as chickenpox. So if someone who has never had chickenpox touches a shingles rash (if present), they could get chickenpox — but this is very rare and preventable by avoiding direct contact.
This is why people with a rash from the live vaccine are advised to keep it covered and avoid close contact with those who haven’t had chickenpox or are pregnant.
