Vaccines offer your child protection against serious illnesses like polio, measles, and whooping cough; but like all medicines they may cause side effects that are both normal and harmless. Knowing what reactions are common will put your mind at ease when giving shots to your children.

Normal Reactions to Vaccines

These vaccines contain components from diseases they protect your child against, but do not cause the actual disease itself. Instead, they stimulate their body to produce blood proteins called antibodies in order to combat those illnesses - for instance if your child came in contact with whooping cough during vaccination, their body would recognize and attack it effectively with its arsenal.

Mild reactions after receiving a travel vaccine elanora indicate its success. These reactions indicate your child's body producing antibodies, and should fade on their own within days or less. Some symptoms might include:

Tenderness or redness at the site of injection; slight swelling at the shot site; fusiness; low-grade fever (fever below 101F); difficulty or excessive sleeping are some possible side effects from childrens vaccinations other potential reactions could include:

Uncommon but more severe reactions include: Swelling of one or both legs or arms. Also less frequently occurring reactions may include:

Vomiting, Drowsiness and Loss of Appetite are common side effects that should improve without medical intervention. Speak to your physician regarding appropriate dosing of pain relievers or fever reducers for relief.

When to Contact the Doctor

If your child is allergic to certain vaccines, signs that something is amiss should become evident quickly after receiving them; typically this happens minutes or hours post children's vaccinations.

Watch for anything unusual, such as mood or behavior changes, high fever or weakness in your child. Severe reactions are extremely rare - only 1 out of every million children suffer severe reactions - but it is essential that you inform your physician of what symptoms need to be reported in order to get help for your child as soon as possible.

Signs to look out for include:

Breathing issues such as wheezing, hoarseness, hives and pale color as well as weakness are indicators that something may be amiss with an individual's respiratory health. Other symptoms could include fast heartbeats and dizziness with fast heart rates over 105F as well as swellings to face or throat as well as seizures. 

Signs that something may be amiss may include uncontrollable crying that lasts more than 3 hours at once, which indicates a possible issue.

Rarely, some vaccines may lead to serious reactions such as coma, long-term seizures or permanent brain damage - all highly unlikely events and doctors are currently researching this subject in order to understand whether they were caused by vaccines or something else entirely.
