COVID-19 vaccine will help protect you against COVID-19 infection. You may have certain adverse effects, which are natural indications that your body is constructing defenses.

Common side-effects of COVID-19 vaccine

At this time, when the country is reeling from COVID-19, we know that immunization is the only method to protect you from acquiring serious sickness. Getting the injection boosts immunity to the devastating virus that has taken so many lives throughout the world. It should be mentioned that having side effects after receiving the vaccination is typical, but they are only a sign that the vaccine dosage is producing antibodies in your body. There is nothing to be concerned about because the majority of the symptoms go gone on their own within two to three days. Here are some of the most frequent side effects of the COVID-19 vaccination that you may encounter after receiving the injection.

Chills with fever

A frequent adverse effect of the COVID-19 vaccinations is fever with chills and shivering. You may feel an increase in body temperature after receiving the injection. It may rise over 100 degrees Fahrenheit and cause discomfort one or two days following the injection.


Another indicator that the vaccination is working is fatigue or weakness after receiving the injection. You may feel excessively fatigued and drowsy. This might last a day or two at most. Make sure you drink lots of water, eat healthily, and get plenty of rest.

​ Headache

The COVID-19 vaccine contains viral antigens that aid the body in developing antibodies against coronavirus. As a result, the majority of the vaccine’s adverse effects are comparable to those of infection. Headache is a frequent symptom that might be misdiagnosed as a COVID symptom.


Fever, chills, and tiredness are frequently accompanied by nausea. You may feel the need to vomit, which will pass quickly.

Joint discomfort

In most cases, the vaccination also causes body aches and joint discomfort. You could also feel stiff and swollen. This issue is more prevalent in persons over the age of fifty.

Arm Swelling

Mild discomfort can be caused by redness and swelling in the arms following the injection, but it goes away with time. Moving your arms slightly may give some comfort.


In rare circumstances, a person may get diarrhea after receiving the injection. It is a little issue that will resolve itself within a day. Consult your doctor if it does not improve.

​How to cope with these symptoms?

COVID-19 vaccination side effects should only last a few days. Paracetamol can be used to relieve mild side effects such as injection site discomfort, soreness, malaise, pyrexia, and so on. Speak with your doctor if you are having unbearable pain that is interfering with your daily activities. They may give you over-the-counter medications such ibuprofen, acetaminophen, aspirin, or antihistamines. However, do not self-medicate! Apply a clean, cold, or damp towel to the area where you had the injection to relieve pain and discomfort, and then practice some arm exercises. Also, try to stay hydrated to keep the fever down.

If any adverse effects get considerably severe, seek medical attention. This might result in severe discomfort, agony, or redness at the injection site. Seek medical attention if any adverse effects linger more than a few days.

If side effects resembling COVID-19 symptoms continue, get a COVID-19 test and follow local self-isolation recommendations.
