These accompanying symptoms indicate a vaccination side effect
Vaccination reactions are harmless and usually disappear after a few days. This includes: Redness, swelling and pain at the injection site, slight fever, general weakness or feeling of exhaustion, pain in limbs, muscles or joints, slight nausea or other gastrointestinal complaints, slight headache. The following symptoms may be signs of more serious side effects: severe headache associated with dizziness, nausea and confusion may indicate meningitis.
High fever in small children can in rare cases lead to febrile convulsions. Rashes, itching, shortness of breath and a drop in blood pressure may indicate an allergic reaction, some of which may be severe. A slight fever after vaccination is one of the harmless reactions to vaccination.
These indicate the normal reaction of the immune system to the vaccine. In most cases, such temporary symptoms disappear again after a few days. Especially if there is only a slight increase in temperature, the fever should not be actively lowered with medication, as this can reduce the success of the vaccination.
However, caution is advised with children and babies. It should always be discussed with the pediatrician how to proceed in case of fever after vaccination. If a vaccinated person develops a very high fever and shows other symptoms, such as severe headaches, confusion or seizures, a doctor must be consulted immediately or even an emergency doctor must be called.
These can be potentially dangerous complications. However, such serious courses of events are hardly ever seen nowadays. A reddening at the injection site is a quite frequent vaccination reaction and usually completely harmless.
The body reacts to the vaccination with a slight and also desired inflammatory reaction. The increased blood circulation around the injection site is reflected in a redness and sometimes swelling. Usually the redness at the injection site disappears completely after a few hours or days.
If the reddening is accompanied by strong general symptoms such as shortness of breath or dizziness, a doctor should be consulted without fail, as this may be a very rare but dangerous allergic reaction to the vaccine or its individual components (chicken protein, gelatine, stabilizers, preservatives). Pain at the vaccination site is also a frequent and harmless reaction. In most cases, the pain occurs shortly after vaccination and lasts from a few hours to days.The pain may be limited to the injection site, but may also be similar to aching muscles in the entire arm or leg. In both cases it is a slight inflammatory reaction caused by the vaccination. If the pain lasts much longer than a few days or even gets worse after a few days, a doctor should be consulted again and a report of the previous vaccination should be given.
