After receiving the COVID-19 vaccine, some people complain that they experience symptoms resembling Corona virus infection, such as fever, chills, and body aches. However, that doesn't mean it's a symptom of COVID-19, but a follow-up event after immunization or AEFI
Post-immunization follow-up (AEFI) is any condition or he alth disorder that occurs after immunization. However, this condition does not always have a cause and effect relationship with the use of vaccines.
Although all types of vaccines used in the national immunization program are very safe and effective if the management and administration is right, there is no guarantee that the vaccine recipient will not experience AEFI, because this is a natural reaction from the body and can vary from person to person. everyone.
AEFI can be mild symptoms, such as feeling unwell, or severe symptoms, such as a severe allergic reaction that causes shortness of breath.
About Post-Immunization Follow-Up (AEFI)
Giving vaccines can trigger side effects in some people. Generally, the side effects that appear are mild, temporary, not always present, and depend on the condition of the recipient's body.
However, these side effects still need to be monitored and evaluated further. If a follow-up event occurs after immunization, the National Committee for the Assessment and Management of AEFIs will help deal with it.
There are several reactions that can occur after administering the COVID-19 vaccine, including:
- Local reactions, such as COVID arm or appearance of pain, redness, swelling at the injection site, and cellulitis
- Systemic reactions, such as fever, muscle aches throughout the body, joint pain, weakness, and headache
- Other reactions, such as urticaria, anaphylactic shock, and fainting
Severe AEFI, such as anaphylactic shock, is rare. However, to be sure, you will be asked to wait for 30 minutes to monitor whether there are complaints that arise after vaccination. That way, if a complaint does arise, the doctor can immediately provide treatment.
Adverse events after immunization are divided into five categories, namely:
- Reactions related to vaccine products, namely AEFI triggered by one or more components contained in vaccine products
- Reactions related to vaccine quality defects, namely AEFI triggered by one or more vaccine quality defects, including vaccine delivery equipment provided by the manufacturer
- Reaction related to incorrect immunization procedures, namely AEFI triggered by inadequate vaccine handling
- Anxiety reactions related to immunization, namely AEFI that occurs due to fear or anxiety when giving vaccines
- Coincident events, namely AEFI caused by things other than vaccine products, immunization errors, or anxiety due to immunization
AEFI can affect otherwise he althy individuals and should be checked immediately. Therefore, if you experience a reaction like the one mentioned above after receiving the vaccine, immediately contact the nearest he alth facility for treatment.
Differences in AEFI and Symptoms of COVID-19
After the COVID-19 vaccination, some people will experience side effects in the form of fever and mild body aches. However, that does not mean you have symptoms of COVID-19. The side effects included in this AEFI indicate that the body's immune system is responding to the incoming vaccine.
However, the COVID-19 vaccination does not immediately give you immunity against the Corona virus. The new immunity will be fully formed within 28 days after the second dose of vaccine is injected.
There have been several case reports where people were exposed to COVID-19 after receiving the vaccine. In these cases, some feel symptoms, some do not. Symptoms of COVID-19 that can be felt include:
- Fever or chills
- Shortness of breath
- Body aches or muscle pain or myalgia
- Sore throat
- Loss of sense of taste and smell (anosmia)
- Nausea and vomiting
Because these symptoms can be confused with AEFI, a doctor's examination is required, either in the form of a physical examination, examination of antigens and antibodies, or a CT scan.
Covid-19 vaccination does not guarantee 100% of the body will be immune to Corona virus infection. However, vaccination can reduce the risk of complications due to COVID-19 which can indirectly reduce mortality from this disease.
So, even though you have received the COVID-19 vaccine, still obey the applicable he alth protocols and be aware of complaints on your body. Contact your doctor immediately if you feel AEFI or symptoms of COVID-19 as mentioned above so you can get the right examination and treatment.
