Vaccine شنگرکس To prevent Skin diseaseThe British pharmaceutical company GSK arrived in Brazil in August 2021, almost a year after the regulatory approval of the National Health Surveillance Agency (Anvisa).
The manufacturer promises that two doses are administered, with an interval of two months between applications. More than 90% efficacy in people over the age of 50, one of the vaccine target populations.
However, immunosuppressants are also recommended for any adult over the age of 18 who is at high risk of infection, such as a patient. immunocompromised. This is the first time that such a signal has been received in the country. Previously, only MSD’s immunizer, Zostavax, was approved in Brazil, but not for the general public.
No vaccine is available from the National Immunization Program PNI. How do full immunizations cost? 1,686 Reis In the private market, see below what are the indications for vaccination and what are the prospects for its inclusion in the public health system.
1) What are the vaccine recommendations?
Vaccines, according to Invisa GSK (Shangrix) With the virus inactive Is indicated for. Adults 50 years and older And adults 18 years and older At increasing risk of shingles, Usually people undergoing cancer treatment, people living with HIV, who are going through bone marrow or organ transplant, lupus, multiple sclerosis, etc.

Already vaccinated MSD (Zostavax)Developed with live attenuated virus since early 2014 and approved by regulatory agency, It is not indicated for immunocompromised.
According to the Brazilian Society of Immunizations (SBIm), it is equivalent to 14 times the varicella vaccine in strength, and has been approved for use in a single dose in adults. Immunity People over the age of 50 (who may develop a normal immune response). The vaccine also showed protective efficacy against about 69.8% shingles.
Because herpes zoster affects people who have chicken pox, immunizations are recommended for at-risk groups: people over the age of 50, especially SBIM vice president Isabella Ballai. People over the age of 60, and those who have a weakened immune system, regardless of age.
The vaccine is used to prevent herpes zoster, post-herpetic neurology (a persistent pain that can last more than three months) and other complications such as facial paralysis, experts say. “And the older you get, the more dangerous it is. [de ter a doença]”
As far as young people are concerned, Bilalai says it is rare for patients who do not have a weakened immune system.

What is the disease and what are the symptoms?
Known as copper, If not diagnosed and treated early, shingles can have serious consequences.Which can affect the nerve endings of the eyes, ears and face, causing paralysis, hearing and visual impairment.
A recent example is the case of singer Justin Bieber, who was diagnosed with Ramsey Hunt Syndrome, an ear herpes zoster.
The disease is caused by the same virus that causes chicken pox (chicken pox), called varicella zoster, and is different from cold sores. The most common condition is to affect people or people with a weakened immune system, such as an infection or other health problem.
According to the Ministry of Health, the following are the main symptoms of the disease before specific injuries (and usually traumatic).
- Neurological pain;
- paresthesias (tingling, numbness, numbness, pressure, etc.);
- Local irritation and itching;
Bilalai added that Shingles is not transmitted to a person who is protected from chicken pox (such as all those who have chicken pox).However, skin lesions that infect people who are infected with the virus can cause chicken pox.
“You will not have shingles, now a child who has not had chicken pox and has not been vaccinated can get chicken pox from this adult. [que está com o vírus da varicella-zóster]”, Says Balalalai.
How much does a vaccine cost? How should they be managed?
The Shingrix (GSK) dosage schedule consists of two immunizations at two-month intervals. The cost per application is R $ 843 (1,686 reis in total).
Zostavax (MSD) is given in a single dose regimen, with an average cost of R $ 570.
“For those who have already received the vaccinated vaccine (MSD), we recommend taking these activated vaccines (GSK), as the low vaccine usually provides protection for up to four years. More effective.” , Details above. “And people who have had herpes zoster and are at risk should also be vaccinated, because the risk remains: the disease can occur more than once.”
Vaccines are not in PNI.
Both GSK and MSD are not in the Immunizer National Immunization Program, PNI, which makes access difficult for those who need the vaccine and unable to pay the market price.
For the vice president of SBIm, the inclusion of these vaccines in the public system is “always desirable”, especially for those over 60 years of age.
Nevertheless, she points out that since this availability depends on a number of factors, such as cost-effectiveness studies, the best and “fastest” way may be to get these immunizations from the Special Immuno Biological Reference Centers (CRIE), Health Units Public and Free The vaccine for immunodeficiency carriers is not available at PNI.
O g1 The Ministry of Health was asked about the possibility of incorporating these vaccines into the public system, but no response was received from the Ministry till the last update of this report.
