Vaccines, as well as any other medicine may cause adverse reactions. Most existing vaccines with proven safety profile and therefore serious side effects are very rare. It is important to note that, thanks to the widespread use of vaccines mankind is “saved” by a number of fatal diseases that have taken millions of victims each year. In medicine since ancient times there postulate Primum non nocere! (Above all, do no harm). As a general rule in the appointment of any treatment, research, prevention, etc. to assess the benefit – risk for the patient. In this respect, the risk of adverse reactions following administration of a vaccine is much smaller compared to the potential benefit that carries it, protecting the body against deadly diseases.
However, various vaccines may have some side effects, most of which were mild and resolved within a few days. These include:
– Pain at the application of the vaccine. It usually resolves within several days.
– The temporary pain that is caused during the administration and then usually leads to the development of fear of vaccination. This can also be called a side effect of vaccination. It is known that 1 in 10 people avoids the administration of vaccines owing to these reasons.
– Redness and swelling around the injection site. In this case, the benefit may be putting a cool compress on the site of application. Thus relieving local reaction.
– Transient flu-like symptoms. These include: a slight increase in temperature, vomiting, abdominal pain, headache, irritability. These side effects occur in 1 in 4 children vaccinated. Appear a short time after administration of the vaccine itself, and should disappear within 1 to 2 days. If the symptoms persist longer or are more pronounced need advice.
Otherwise there is the question at vaccination with the measles, mumps and rubella. It is composed of three components against the infectious agents. Usually the side effects of this vaccine occurred a little later:
– After 6-10 days begins to “work” measles. It can cause fever, measles-like rash on the body, violation appetite.
– After 2-3 weeks mumps vaccine can cause mumps symptoms – fever and enlarged lymph nodes.
– After 12-14 days Rubella component can cause mild fever and rash.
Do I need treatment?
Usually the body temperature is only slightly increased. What you can do is to leave the child alone with one layer of clothing. Give him more fluids, and breast-feeding – do it at frequent intervals. It is not usually necessary administration of antipyretics, but if your child is experiencing apparent discomfort can give him paracetamol, according to age and weight it. It will relieve painful sensation.
When it is necessary to consult a doctor?
Serious side effects from vaccines are very rare, but possible their appearance. Some of the more serious symptoms may include:
– Allergic reactions such as rash, itching, swelling and swelling of the face or around the mouth, difficulty breathing, low blood pressure;
– Joint pain.
If you have these symptoms, you need to visit the doctor treating the child to assess his condition, assessing whether an adverse reaction to the vaccine.
