The shingles vaccine is recommended to prevent shingles (herpes zoster), reduce pain during an outbreak, and lower the risk of postherpetic neuralgia, a complication that affects the nerves and skin, causing burning pain that can last for up to six months.
This vaccine is sold under the brand name Shingrix. It is a recombinant vaccine that contains proteins from the varicella-zoster virus, which stimulate the immune system to produce antibodies that protect against shingles.
The shingles vaccine is available and can be administered at most pharmacies and can also be given in clinics or hospitals. It can also be given to people who have already had shingles.
Indications for use
The shingles vaccine is recommended to:
-
Prevent shingles from developing;
-
Reduce the risk of shingles recurrence in people who have already had the infection.
The vaccine is routinely recommended for adults aged 50 and older, as this is when people who had chickenpox in childhood are more likely to develop shingles.
The varicella-zoster virus, which causes chickenpox, can stay dormant in the body for many years and reactivate later when the immune system becomes weaker.
In addition, the shingles vaccine (Shingrix) is also recommended for adults 19 years and older who are or will be immunocompromised due to disease or therapy.
How it works
The recombinant shingles vaccine (Shingrix) contains a protein called glycoprotein E (gE), which is produced using recombinant DNA technology.
This protein helps stimulate the immune system to produce antibodies against the varicella-zoster virus, preventing the virus from reactivating and causing shingles.
Dosing schedule
The following table provides dosing information for the shingles vaccine based on indication:
For people with HIV or AIDS, the shingles vaccine can be given under medical supervision regardless of CD4 count, although better responses are expected when CD4 counts are higher and viral load is controlled.
If recommended by a healthcare provider, Shingrix can be administered at the same time as other vaccines such as the inactivated flu shot, COVID-19 vaccine, pneumococcal polysaccharide vaccine (PPSV23), or the reduced-antigen diphtheria-tetanus-acellular pertussis vaccine (Tdap), provided that each is injected in a different site using separate syringes.
Shingles vaccine side effects
The most common side effects of the shingles vaccine include:
-
Headache;
-
Nausea, vomiting, diarrhea, or abdominal pain;
-
Muscle pain, joint pain, or pain in the arms or legs;
-
Fatigue, fever, chills, or general discomfort.
Injection site reactions may include pain, redness, swelling, itching, bruising, firmness, or warmth, as well as swollen lymph nodes near the injection area.
Although rare, anaphylactic reactions can occur. For this reason, the vaccine should be administered only in hospitals, pharmacies, or clinics by healthcare professionals who can provide immediate medical care if necessary.
Contraindications to use
The shingles vaccine (Shingrix) should not be given in the following situations:
-
Severe allergic reaction to a previous dose or any component of the vaccine;
-
Moderate or severe acute illness;
-
Active shingles episode.
The vaccine should generally be delayed during pregnancy and may be given during breastfeeding if indicated by a healthcare provider.
People with bleeding or clotting disorders should inform their doctor before vaccination, as extra care may be needed for the intramuscular injection.
The shingles vaccine is not recommended for individuals under 19 years of age.
