Varicella vaccine

Varicella vaccine

The vaccine fights the pox virus and is made with the attenuated varicella-zoster virus. It is not considered mandatory and is not included in the National Immunization Program of the Ministry of Health. In 2013 it was added to the triple viral vaccine, forming the viral tetanus vaccine and was offered by the Unified Health System (SUS). > Diseases that the chickenpox vaccine prevents

Chicken pox is a common disease in children and adults. A person with chickenpox may have hundreds of itchy, broken, and itchy blisters. Most cases of chicken pox occur in children younger than 10 years. The disease is usually mild, although serious complications may occur in some cases. Usually, adults and older children become more seriously ill than younger children.

The main symptom is the balls that appear on the skin. A common child develops from 250 to 500 small blisters that itch on the red dots and blisters on the skin. Chickenpox is easily transmitted to other people. Contagion occurs through contact with the bubble fluid or through coughing or sneezing. Generally, the vaccine prevents the disease completely or makes it very moderate. Even those who are infected with a mild version of the disease can be contagious.

The effectiveness of the vaccine in preventing the problem is almost 100% if both doses are taken. With one, the disease may still occur, but the chances of complications, hospitalizations and deaths are substantially reduced. It is important to say that even those who are infected with a mild version of the disease can be contagious and start outbreaks.

Indications

It is recommended in routine for children from the age of twelve months. There is, however, no age limit for its application, which means that any susceptible individual (who has not had chickenpox or has not been adequately vaccinated) should be immunized.

The vaccine is offered free of charge to priority view of public health. They are: children under two years of age, children exposed to hospital settings, some health professionals, people living with immunosuppressed patients or those who take prolonged use of acetylsalicylic acid.

It is interesting to note that susceptible persons who have had contact with patients may if you take the vaccine if you take it in less than 72 hours.

Pregnant can take this vaccine?

No. If the pregnant woman contacts a sick person, the recommendation is to take specific immunoglobulin available from the Special Immunobiological Reference Centers (CRIEs).

Necessary doses

In the SUS, the single dose dosing regimen is used in the SUS. 15 months of age. The Medical Societies recommend a two-dose regimen from the age of 12 months, with at least three months interval (for children under 11 years) or one month (for the elderly). The application should preferably be made at 12 months and 15 months.

Administration of the varicella vaccine

It is administered subcutaneously

Contraindications

Like other attenuated virus vaccines, its use in people with congenital or acquired immunodeficiency, with neoplasias and in immunosuppressive drug use is contraindicated. It is also not recommended for use in people with previous dose anaphylactic manifestations or one of the components of the vaccine.

Women of childbearing potential should avoid pregnancy for 30 days after immunization. People with acute or HIV lymphoid leukemia under certain conditions and rigorous follow-up as part of research protocols have been immunized with reduced risk of complications and death associated with the disease in these patients

Any hypersensitivity to components of a vaccine makes it contraindicated in addition to the anaphylactic reaction after taking one of the doses.

Possible side effects

In people with normal functioning immune systems, symptoms such as redness in the skin, ache. In some cases, two to four vesicles may be seen at the injection site. Fever may also occur. Anaphylaxis is rare.

Where to Find the Varicella Vaccine

Since September 2013, the varicella vaccine is available in the SUS, which is incorporated into the triple viral vaccine, forming the tetra-viral vaccine. It, alone or combined with the triple virus, is found in private clinics for people of any age, provided they are susceptible. Some medical covenants cover this vaccine in the private healthcare system.

Frequently Asked Questions

Can I update my immunization card at any age?

Not only can it, but it should. Although it is best to follow the vaccination schedule and immunize at the recommended ages, it is important to take the vaccines that are delayed. However, this rule only applies to vaccines that continue to be recommended in adulthood, such as tetanus, pertussis, and diphtheria. However, vaccines you should have taken during childhood only, and that miss the recommendation for adults, because the risk of the disease no longer exists, do not need to be taken. An example is rotavirus, a disease that is very serious in childhood and must be vaccinated in the period, but that for adults does not cause impact beyond annoyance, losing the need for vaccination. Therefore, it is important to follow the timing of birth to third age respecting the priority ages.

If I do not remember having taken the vaccine, can I go to the post and repeat the dose?

Yes. The best measure to do in these cases is to check the vaccination card. But if you missed it for some reason, or thought you were vaccinated, but it is not on the record, the best thing to do is to get vaccinated, albeit repeatedly. "However, you need to be aware of live virus vaccines for serious diseases, such as yellow fever, because there is little chance that the virus will cause the excess virus to cause the disease," says immunologist Eduardo Finger, research and development SalomãoZoppi Diagnostics, in São Paulo. Other than these cases, the best thing to do is to make sure and take the vaccine. "Always remembering that vaccines are even safer when the timetable is followed."

People who are allergic to any vaccine will not be able to take it any more?

In general, it is very difficult for a person to be allergic to the vaccine in yes, but to other elements that are within it. Contraindications are, according to pediatrician Isabella, only for people who have already suffered an anaphylactic shock in the following cases: for measles vaccines, measles, mumps, rubella and yellow fever vaccines are contraindicated because these live viruses are grown in the food before go to the vaccine; in cases of mercury anaphylaxis are contraindicated vaccines with this element, in general those administered by SUS; and whoever has had anaphylactic latex shock should know about the vaccines at their standard vaccination site, as some may contain remnants of the substance.

If I lose my card, will I have to vaccinate again?

Yes, because vaccine is only that vaccine that has been registered. If you take your vaccines at a private clinic, the location will likely record a history of your vaccines, so you do not have to take it again. However, the public network has not yet been able to computerize these data, so a person who is vaccinated in the public network and loses his / her card will need to take all recommended adult vaccines again.

The importance of caregivers in the oral health of adults with disabilities

The importance of caregivers in the oral health of adults with disabilities

According to a recently published study, caregivers play a key role in the oral health of adults with physical and mental disabilities. But little is known about effective oral care methods for these people who are unable to perform oral prevention practices autonomously. According to the study, people with physical and mental disabilities usually have a high prevalence of caries, periodontal disease and loss of the dental element.
