Common Vaccination reactions

A vaccination reaction is an injury or a condition that is caused as a result of vaccination given in order to protect from the disease. Rarely there may be some serious reactions caused due to this vaccination but this vaccination is less risky than the disease that may be caused due to absence of vaccination. Always the vaccination reactions are common but they are harmless. There may be some severe allergic reactions also called as anaphylactic reactions caused due to any vaccine but they may be rare.

Severe vaccination reactions sometimes happen in few minutes after the immunization. Some of the allergic reactions are breathing trouble, weakness, wheezing, fast heartbeat, hives, dizziness, paleness or sometimes cause swelling of throat. The following includes the different reactions for different types of vaccines. The vaccination reactions for Diphtheria-Tetanus-Pertussis (DTaP) are as follows.

1) Pain, swelling or redness at the injection site. It may be for 24 to 48 hours and is caused from 25% to 45% of children. It can be reduced by the intake of ibuprofen or by placing a cold wet cloth on the tender area.

2) Fever may be for 24 to 48 hours over 102 degrees Fahrenheit that may be caused from 7% to 26% of children. Intake of acetaminophen would be suitable medicine for this. 

3) 4th or 5th dose of DTaP can lead to large swelling of arms or leg. This swelling may be up to 4 inches and it occurs 5% of children. But this swelling would get resolved in 3 days. No particular treatment is required for this.

4) Other reactions would be like mild drowsiness that occurs in about 15%, poor appetite that occurs in 10 to 15% of children. Some times leads to prolonged crying for less than 3 hours.

5) One or two weeks later, a painless lump may appear at the injection site. But this is harmless and disappears in 2 months.

Some other vaccination reactions due to which serious reactions occur are, 104 degree Fahrenheit fever, crying for about 3hours or more, unusual cry, seizures which occurs very rarely, dizziness, fainting, and some other unusual reactions.

The vaccination reactions due to the vaccine for measles, mumps, and rubella normally appear from 5 to 12 days after the vaccination. They are i) 103 degree fever in about 10% of children. This can be treated by intake of ibuprofen or acetaminophen. ii) one to six weeks later, a mild pink rash might occur on the body after getting the vaccine. It may last for 2 to 3 days and no particular treatment is required for this. iii) Some children might get swollen lymph glands after three or four weeks of vaccination. Some may get pain or stiffness in their joints. iv) Rarely, low blood platelets, leads to bruising and bleeding into skin.

Vaccination reactions for Polio vaccine (IPV) are: i) sore injection site. But this needs no special treatment. Intake of ibuprofen or acetaminophen would provide some relief. ii) Sometimes fever over 102 degree that occurs in 1% to 4% of children.
