Chicken pox is a disease having which one can have better immunity for the rest of his life, but chicken pox vaccine has been already been introduced to help people combat the virus! It usually develops in children and at times in adults. This disease in one hand makes the children well immune for the whole life and hence there is often a controversy over the introduction of the vaccine that can prevent the disease.
Reason behind the development and popularization of the vaccine
The virus that causes chicken pox is called Varicella Zoster. The disease is contagious and the patient must be kept in a separate room. The main characteristics of the disease include rashes, fever, fatigue, headache, itchiness etc. The chicken pox vaccine is called Varivax and got its approval in 1995. Since then it has been under profuse use especially in Australia. The chicken pox vaccine is a live one containing live virus that initiates combating response towards the chicken pox virus.
This vaccine is being immensely used in Australia since people there even experienced deaths and hospitalizations because of it. Every year there comes a season where the chicken pox virus reactivates itself and the disease spreads. Moreover the vaccination is essential since the virus can cause serious damage to the fetus if a pregnant woman develops the disease. If a newborn gets the disease from the mother, then it can cause fatal results in the baby. In most countries, this vaccination is thus essential for everyone especially children.
Affectivity of the vaccine
Often it is seen that chicken pox develops complicacies and does not remain mild as it should be. However the chicken pox vaccine is highly effective in preventing the disease. So it is evident that those adults and children who are vaccinated are likely to remain fit even if there is an outbreak of chicken pox in the locality. Presently due to vaccination, this disease is experienced by lesser number of people. But this vaccine may not work and there are cases of exceptions as well. Some people are also recommended to not to take the vaccine. So prior to vaccination, compatibility tests are usually done to ensure that the vaccine suits the person.
Side-effects of the vaccine
The vaccine has certain side effects that obviously create specific disadvantages. Some of the side effects are listed below:
• It often happens that 2% of the vaccinated people develop chicken pox but of mild intensity.
• 10% people experience mild fever after taking the injection
• In some people rashes may develop after the vaccination
Some people are also advised to not to take the vaccine, the list includes those people who are allergic towards neomycin or gelatine, children who are aged nine months or younger than that, pregnant women, people who are already suffering from another disease, HIV positive people, people who have reacted adversely reacted to the vaccine before and those who are getting treated by chemotherapy.
The vaccine itself can often cause death or serious damage to a person due to intense reactions. However researches are going on to bring down the reaction caused damage by the vaccine. The disease itself helps to prevent Shingles, a more dangerous disease but the advent of the chicken pox vaccine has caused the occurrence rate of shingles higher.
