Can children still catch chicken pox after they have been vaccinated?

Can children still catch chicken pox after they have been vaccinated?

Yes: Vaccines have decreased illness rates dramatically, but there are some people who don't respond to vaccines and are still susceptible. This is why multiple doses of each vaccine are needed (ie boosters). It is also a reason that a large percentage of the population needs to be immunized to make a dent in the transmission of a disease. Herd immunity protects if the immunizations aren't effective. ...Read more

Caused by the varicella-zoster virus, chicken pox results in a blister rash that starts on the stomach, back, and face and spreads throughout the entire body. These small itchy blisters eventually scab over. Associated symptoms include itching, fatigue, malaise, and a fever. The most effective method to prevent spreading of the varicella virus is ...Read more

What are the symptoms of chicken pox in a child who has been vaccinated already?

A mild case: The varicella vaccine does not totally prevent chickenpox. The patient usually will get a very mild case, sometimes only a handful of lesions and no other symptoms. A few will actually get a URI and viral illness symptoms with a more typical rash. ...Read more

What do the symptoms of chicken pox look like, in a child who has been vaccinated twice?

Chickenpox sypmtoms: It is very rare for a child who has had 2 doses of the varicella vaccine to still contract chickenpox. The infection is usually a lot milder, no symptoms may appear and there could just be a few blisters (resembles the appearance of a dew drop on a leaf) - with or without the itch. ...Read more

Who gets vaccinated for chicken pox?

Children over 1 year: Normal, healthy children over 1 year of age can get the chicken pox vaccine. A child who has already caught natural chicken pox disease usually doesn't need a vaccine (the parent should ask the child's doctor about it). Adults who are not immune to chicken pox may also be able to get the vaccine. ...Read more

Can chicken pox make you sick after being vaccinated?

Can chicken pox make you sick after being vaccinated?

Yes: The vaccine is thought totally protective for 85% of kids after 1 dose & >95% after two. Some vaccinated kids get a mild case of it (5-20 spots) while the average wild case= 200+spots. The vaccine has cut the death rate dramatically and reduced hospitalizations due to complications. ...Read more

Can a child have chicken pox even if she has been vaccinated?

Chickenpox: Chickenpox after vaccine can occur in two different situations. The more common of the two is a breakthrough infection, which is believed to be caused by a wild-type varicella virus. The second situation, in which you catch chickenpox from the chickenpox vaccine itself, is extremely rare. Second-time chickenpox cases are typically very mild. ...Read more

Is it possible I can get the chicken pox if I got vaccinated about 15 years ago?

Yes: You are very likely to have receiced one shot which was a standard back then. Later on, it was found that one shot did not provide adequate protection for a prolonged period. A booster dose vaccination has typically been given in 4-5 years. ...Read more

Is it possible to get chicken pox if I've never had them but have been vaccinated?

Not likely: The protection from a single vaccine dose in an adult is about 85% while having a second a month later brings it up to 95% or better. If you did get the wild disease the vaccinations would limit the intensity of the illness and reduce any risk of the known complications. ...Read more

Might a vaccinated child get sick when exposed to a non-vaccinated child with chicken pox?

Might a vaccinated child get sick when exposed to a non-vaccinated child with chicken pox?

Partial protection: Some vaccines give partial protection to some kids and these will be susceptable to infection by wild disease carriers. Some of the measles this year in houston were traced to an imported case infecting kids with no, one or two doses. The chickenpox vaccine has essentially ended CP deaths (were 50/yr) but we still see breakthru cases, all of which can develop secondary illnesses like invasive strep. ...Read more

If one of my students contracted chicken pox, should I be concerned I've never been vaccinated?

Yes, but...: Since the vaccine has been routinely given starting in the 1990's, the number of people who have immunity because of previous unknown infection has seriously decreased. Thus it depends upon your age. If your were born prior to introduction of the vaccine, you may be immune, but do not count on it. Best choice is to immunize for safe protection! ...Read more

What are the arguments about chicken pox vaccination?

What are the arguments about chicken pox vaccination?

?? argument???: After the approval of CP vaccine many seemed happy to have their child or grandchild get the disease "because we all did it that way".Certainly when there was no option that was true. They were unaware of the 50 related fatalities/yr & 10, 000 hospitalizations for complications such as reyes syndrome & flesh eating bacteria.Many still choose to ignore the risks. So sad. ...Read more

Does getting vaccinated for chicken pox guarantee that you will never get it in your life?

Does getting vaccinated for chicken pox guarantee that you will never get it in your life?

No: A single dose given over the age of one is considered 100% preventative of major complications but only 85% protective against the disease. After two doses at least 1 month apart, the protective level rises to 95%. Anyone with an immunity problem may have a muted response to any vaccine. ...Read more

Does getting vaccinated for chicken pox guarantee that you will never get it in your life? Test basic consult.

Basic answer=no: A single dose given to non-immune person will generally confer immunity to 85%, with 2 doses at least a month apart raising the number to 95%. Those not fully immune have been shown to at least avoid the major complications (death, pneumonia) after at least one dose. Since the vaccine has only been widely available since the 1990's, it will take decades before lifetime immunity can be confirmed. ...Read more

Can a vaccinated person catch chicken pox from somebody's shingles?

Can a vaccinated person catch chicken pox from somebody's shingles?

Unlikely an issue: A properly vaccinated kid would have about a 5 % risk of ever getting varicella. Ophthalmic shingles is only contagious through the debris from the lesions, not though droplets like regular chickenpox. If the vaccinated child did not have direct contact with the lesions or debris there would be no risk of infection. ...Read more

Can you please describe the arguments against chicken pox vaccination?

Early on -expense: It took 16 yrs +/- to get the chickenpox vaccine through the fda approval process for generalized use. It was available to select populations, but they considered the expense too much to justify broad distribution. When the 50/yr deaths + 10k hospitalizations + 50x increase in invasive strep disease+ work loss by parents was factored in, they finally relented & let it be used. ...Read more

What do you suggest if my child got the chicken pox vaccination can she still get chicken pox?

What do you suggest if my child got the chicken pox vaccination can she still get chicken pox?

Possibly: Introduced in the late 70's in japan, the current CP vaccine was not adopted in the us until the 90's. There are good data that one dose removes the risk of death with cp, but likely only 85% get protective immunity from 1 dose, with that improving to >95% after 2 doses given at least a month apart. Time will tell if future boosters are needed but with 30+ years of worldwide data it looks good. ...Read more

What are the odds of me getting chicken pox if I've been exposed and never got any vaccination?

What are the odds of me getting chicken pox if I've been exposed and never got any vaccination?

Likely: Chicken pox is easily shared among people who don't have immunity. Immunity is through infection or immunization. It can be contagious a day or 2 before the blisters appear, and remains contagious until all the blisters crust over. It can take 10-21 days to show symptoms once you've been exposed. A vaccine can prevent serious disease. Go to your doc if you get the rash to properly document. ...Read more

Is it possible for someone with opthamalic shingles transfer chicken pox to a vaccinated child?

Is it possible for someone with opthamalic shingles transfer chicken pox to a vaccinated child?

Unlikely to happen: There are a few vaccinated kids who remain less than fully protected, especially if they have not completed the two shot series. However, shingles is not as contagious as the wild chickenpox, it has no airborne phase. To be exposed the child would have to have direct contact with the material from the caretakers wounds. Simple hygienic care/handwashing/etc will avoid passing it on. ...Read more

Can your child get the chicken pox after their vaccination by being exposed to another child with them?

Can your child get the chicken pox after their vaccination by being exposed to another child with them?

Yes, it's possible: It is possible for this to happen, since the chicken pox (i.e., varicella) vaccine is not 100% effective. The vaccine increases the probability of not being infected with the chicken pox virus, but it is not an absolute guarantee. However, a child without the vaccine will almost certainly become infected if exposed (because the virus is so virulent), but the child with the vaccine probably won't. ...Read more

Is it possible for a vaccinated child to be carrying chicken pox and give it to an unvaccinated person?

Is it possible for a vaccinated child to be carrying chicken pox and give it to an unvaccinated person?

Very rarely.: You can only be contagious with chicken pox if you actually have the infection. People vaccinated against chicken pox have about a 90% chance of being immune. If someone was vaccinated and didn't become immune, that person could get infected with the chicken pox and then pass it on. ...Read more

Can your child still get the chicken pox after a vaccination, by being exposed to another child with chicken pox?

Possible but rare: After one dose of chickenpox vaccine, most children will have enough immunity that they won't get chickenpox even if they are exposed. After two doses, at least 95% of kids have good immunity against the disease. So, there is a slight chance for some kids to get chickenpox even with vaccination. In those cases, the disease is usually pretty mild. ...Read more

If my 4 month old has chicken pox is it also likely my 6 year-old will still them too even if he has already been vaccinated?

If my 4 month old has chicken pox is it also likely my 6 year-old will still them too even if he has already been vaccinated?

Possibly: The varicella vaccine is considered 85% protective against infection with 1 & >95% with 2 doses. A single dose is thought to eliminate risk of severe disease. If your 6yo was vaccinated, his risk is low but 10-21 days after the 4mo broke out it should appear it it is going to. Transmission to susceptible family approaches 100%. ...Read more

My son has 4 cases of chicken pox at school. He's vaccinated but I'm worried he still gets it and transmits it to his 3 months old baby sister?

Low risk: No vaccine is 100% effective, but the risk of getting varicella in a vaccinee is very low. And the risk of a three month old then getting it is even lower. If you are that concerned, hold your child back from school until all the cases have resolved. ...Read more
