Hepatitis B is a very safe vaccine. Most people do not have any problems with it. The vaccine contains non-infectious material, and cannot cause hepatitis B infection. Some mild problems have been reported Soreness where the shot was given (up to about 1 person 4) Temperature of 99. 9°F or higher (up to about 1 person in 15). Severe problems are extremely rare. Severe allergic reactions are believed to occur about once in 1. 1 million doses. A vaccine, like any medicine, could cause a serious reaction.
But the risk of a vaccine causing serious harm, or death, is extremely small. More than 100 million people in the United States have been vaccinated with hepatitis B vaccine. DTAP Getting diphtheria, tetanus or pertussis disease is much riskier than getting DTaP vaccine. However, a vaccine, like any medicine, is capable of causing serious problems, such as severe allergic reactions. The risk of DTaP vaccine causing serious harm, or death, is extremely small. Mild Problems (Common) Fever (up to about 1 child in 4).
Redness or swelling where the shot was given (up to about 1 child in 4) Soreness or tenderness where the shot was given (up to about 1 child in 4) These problems occur more often after the 4th and 5th doses of the DTaP series than after earlier doses. Sometimes the 4th or 5th dose of DTaP vaccine is followed by swelling of the entire arm or leg in which the shot was given, for 1 to 7 days (up to about 1 child in 30). Other mild problems include: Fussiness (up to about 1 child in 3) Tiredness or poor appetite (up to about 1 child in 10) Vomiting (up to about 1 child in 50).
These problems generally occur 1 to 3 days after the shot. Moderate Problems (Uncommon) Seizure (jerking or staring) (about 1 child out of 14,000) Non-stop crying, for 3 hours or more (up to about 1 child out of 1,000) High fever, 105 degrees Fahrenheit or higher (about 1 child out of 16,000) Severe Problems (Very Rare) Serious allergic reaction (less than 1 out of a million doses) Several other severe problems have been reported after DTaP vaccine. These include: Long-term seizures, coma, or lowered consciousness Permanent brain damage.
These are so rare it is hard to tell if they are caused by the vaccine. Controlling fever is especially important for children who have had seizures, for any reason. It is also important if another family member has had seizures. You can reduce fever and pain by giving your child an aspirin-free pain reliever when the shot is given, and for the next 24 hours, following the package instructions.

MMR A vaccine, like any medicine, is capable of causing serious problems, such as severe allergic reactions. The risk of MMR vaccine causing serious harm, or death, is extremely small. Getting MMR vaccine is much safer than getting measles, mumps or rubella. Most people who get MMR vaccine do not have any serious problems with it. Mild Problems Fever (up to 1 person out of 6) Mild rash (about 1 person out of 20) Swelling of glands in the cheeks or neck (about 1 person out of 75) If these problems occur, it is usually within 7-12 days after the shot.
They occur less often after the second dose. Moderate Problems Seizure (jerking or staring) caused by fever (about 1 out of 3,000 doses) Temporary pain and stiffness in the joints, mostly in teenage or adult women (up to 1 out of 4) Temporary low platelet count, which can cause a bleeding disorder (about 1 out of 30,000 doses) Severe Problems (Very Rare) Serious allergic reaction (less than 1 out of a million doses) Several other severe problems have been reported after a child gets MMR vaccine, including: Deafness Long-term seizures, coma, or lowered consciousness.
Permanent brain damage These are so rare that it is hard to tell whether they are caused by the vaccine. This information was taken directly from the MMR VIS [PDF – 191 KB] (This information taken from MMR VIS dated 4/20/12. If the actual VIS is more recent than this date, the information on this page needs to be updated. ) VARICELLA A vaccine, like any medicine, is capable of causing serious problems, such as severe allergic reactions. The risk of chickenpox vaccine causing serious harm, or death, is extremely small. Getting chickenpox vaccine is much safer than getting chickenpox disease.
Most people who get chickenpox vaccine do not have any problems with it. Reactions are usually more likely after the first dose than after the second. Mild Problems Soreness or swelling where the shot was given (about 1 out of 5 children and up to 1 out of 3 adolescents and adults) Fever (1 person out of 10, or less) Mild rash, up to a month after vaccination (1 person out of 25). It is possible for these people to infect other members of their household, but this is extremely rare. Note: The first dose of MMRV vaccine has been associated with rash and higher rates of fever than MMR and varicella vaccines given separately.
Rash has been reported in about 1 person in 20 and fever in about 1 person in 5. Seizures caused by a fever are also reported more often after MMRV. These usually occur 5-12 days after the first dose. Moderate Problems Seizure (jerking or staring) caused by fever (very rare). Severe Problems Pneumonia (very rare) Other serious problems, including severe brain reactions and low blood count, have been reported after chickenpox vaccination. These happen so rarely experts cannot tell whether they are caused by the vaccine or not. If they are, it is extremely rare.
