Varicella-zoster virus is part of the herpes virus group and produces 2 distinct diseases, varicella and herpes zoster.
Varicella is a disease that occurs in most cases in children (infectious disease of childhood) and usually has a benign evolution (not serious). Therefore, the administration of the vaccine that protects against contacting this type of infection is not always recommended.
Many pediatricians recommend active immunization of children (passing through the disease), as this is in most cases a mild condition. Immunization of this kind confers immunity that persists throughout life and prevents relapse of the disease.
The vaccine, like all vaccines, can have some side effects and does not usually offer long-term immunity (only for a few years).
However, there are certain population groups where vaccination is against recommended (adults or children with poor immunity, before immunosuppressive treatments, epidemics).
The varicella-zoster virus vaccine contains a live, attenuated virus strain and was approved for use only 15 years ago, although other vaccines have been used in the past.
Recommendations for the administration of varicella-zosterian vaccine:
The varicello-zosterian virus can remain confined to the central nervous system and it can be reactivated whenever the immunity of the person concerned decreases.
Herpes zoster is an extremely painful and unpleasant condition, difficult to treat and which recurs in most cases, is characterized by the appearance of bladder skin lesions (similar to those of chickenpox) and that appear along certain groups of nerves ( dermatomas), most often in the face and chest.
The lesions are extremely painful because they are located on the nerve threads, can be generalized and superinfected if not treated properly (administration of Acyclovir, a powerful antiviral).
Vaccination against varicella-zoster virus is recommended for all high-risk groups or healthy children, around the age of 12-18 months.
Vaccine contraindications against varicella-zoster virus
Special attention to the administration of varicella-zoster vaccine is related to certain special situations that need to be carefully considered by the pediatrician.
This free interval is necessary for proper regeneration of the immune system, which must secrete protective antibodies upon contact with the virus (vaccine).
Adverse reactions to varicella-zoster vaccine administration
Of the adverse reactions that occurred during the administration of the varicello-zosterian virus vaccine, we mention:
