A PPD can be applied before or on the same day that MMR vaccine is given. However, if MMR vaccine is given on the previous day or earlier, the PPD should be delayed for at least one month. Live measles vaccine given prior to the application of a PPD can reduce the reactivity of the skin test because of mild suppression of the immune system. There is no scientific reason for or benefit to separating the antigens.

The tuberculin skin test tells if TB germs are in the body. A small amount of harmless fluid will be put just under the skin on your arm. Two or three days later you must return to the clinic to have your arm checked for a reaction. (The skin test must be repeated if you are not able to return to the clinic within 3 days.) If there is a reaction, the size of the reaction is measured. See similar questions...

If there is little or no change to the spot on your arm, it usually means that TB germs have not entered your body. This is called a negative reading, and you will be given a TB clearance card. If a bump about the size of a pencil eraser or bigger appears on your arm, this means that you probably are infected with TB germs. It is a positive reading, but it does not necessarily mean that you have TB disease. See similar questions...

No. The tuberculosis and Valley Fever skin tests do not cross react. The presence of tuberculosis will not cause a positive cocci skin test nor will the presence of Valley Fever cause a positive tuberculin test. See similar questions...

PPD is a purified antigen from the tuberculosis (TB) bacteria. It is injected under the skin and causes a local skin reaction if the individual has had previous exposure to TB. See similar questions...

No. If an individual did not respond to the first two doses, they will probably not respond to a third. See similar questions...

are a woman born before 1957 who is sure she is not having more children, has already had rubella vaccine, or has had a positive rubella test Do people who received MMR in the 1960s need to have their dose repeated? Not necessarily. People who have documentation of receiving LIVE measles vaccine in the 1960s do not need to be revaccinated. See similar questions...

You may obtain TB/PPD testing from your own healthcare provider or you may visit Children's Hospital’s Employee Health department during drop-in hours for free testing. You do not need an appointment to come in during these times: Remember to bring your Volunteer Health Clearance form when you come for your appointment. Each TB/PPD test is a two-step process and requires two short visits 48 hours apart, so plan your schedule accordingly. See similar questions...

The second dose of MMR can be given anytime, as long as the child is at least 12 months old and it has been at least a month since the first dose. However, the second dose is usually administered before the child begins kindergarten or first grade (4-5 years of age) or before entry to middle school (11-12 years of age). The age at which the second dose is required is generally mandated by state school entry requirements. See similar questions...

Most infants born in the United States will receive passive protection against measles, mumps, and rubella in the form of antibodies from their mothers. These antibodies can destroy the vaccine virus if they are present when the vaccine is administered and cause it to be ineffective. By 12 months of age, almost all infants have lost this passive protection. See similar questions...

The principal strategy to prevent mumps is to achieve and maintain high immunization levels. The Advisory Committee on Immunization Practices (ACIP) recommends that all preschool-aged children at or greater than 12 months of age receive 1 dose of MMR vaccine that all school-aged children receive 2 doses of MMR, and that all adults have evidence of immunity against mumps. As noted below, two doses of mumps vaccine are more effective than a single dose. See similar questions...

Women known to be pregnant should not receive MMR vaccine. Pregnancy should be avoided for four weeks following MMR vaccine. Close contact with a pregnant woman is NOT a contraindication to MMR vaccination of the contact. Breastfeeding is NOT a contraindication to vaccination of either the woman or the breastfeeding child.

The doctor caring for the patient is responsible for placing the skin test. The doctor must first write an order in the chart for the tuberculin skin test and controls. The PPD and control will be sent to the floor in a multiple use vial. 0.1 ml should be drawn into a tuberculin syringe, and the test placed on the patient. The vial should be dated, then stored under refrigeration and protected from light. The remaining contents of the vial are good for 30 days when stored in this manner. See similar questions...

Yes, some of the reported cases are in individuals that have been vaccinated with two doses of MMR. The vaccine effectiveness for 1 dose of MMR is 70-80% and 80-90% for 2 doses. Since no vaccine is 100% effective (even though people are vaccinated, the vaccine doesn't 'take' in every person), it is to be expected that there will be some cases of disease in individuals that have been vaccinated. However, the vaccine is likely to have prevented hundreds or thousands of other cases. See similar questions...

The second dose should be administered as soon as possible. There is no need to repeat the first dose. Can hepatitis A vaccine be given during pregnancy or lactation? We don't know for sure, but because vaccine is produced from inactivated hepatitis A virus, the theoretical risk to the developing fetus is expected to be low. The risk associated with vaccination, however, should be weighed against the risk for hepatitis A in women who may be at high risk for exposure to hepatitis A virus. See similar questions...

Consult with your doctor or state or local public health officials for recommended times if there is going to be a change in the recommended schedule of shots. Rabies prevention is a serious matter and changes should not be made in the schedule of doses. See similar questions...

Yes. Disease exposure, including chickenpox, should not delay anyone from receiving the benefits of the MMR or any other vaccine. What is the most common reaction following MMR vaccine? Most people have no reaction. However, 5 percent to 10 percent of the people receiving the MMR vaccine experience a low grade fever and a mild rash. See similar questions...

Yes. There are no reports of transmission of live attenuated measles or mumps viruses from vaccinees to susceptible contacts. See similar questions...
