The temporary side effects of COVID-19 may include pain and swelling at the injection site, fever, fatigue, nausea, headache, muscle pain and joint pain.
Allergic reactions to the COVID-19 vaccine likely to be extremely rare.
The most common side effect is soreness at the site of injection. Other side effects include fatigue, headache, muscle aches, chills, joint pain, and possibly fever.
According to the FDA, the most common side effects among participants in both the Pfizer-BioNTech and Moderna phase 3 clinical trials were: Injection site pain, Fatigue, Headache, Muscle pain, Chills, Joint pain, Fever
An interesting finding from the Pfizer-BioNTech and Moderna clinical trials is that while the vaccines seem to be just as effective in older adult participants, people 65 and older experienced fewer side effects than younger volunteers. Researchers are still studying why this is the case, but it could have something to do with the declining immune response that comes with age. Because the coronavirus vaccine can provoke “a little bit of an inflammatory response,” it may be that older adults react less to the medicine if they have “a blunted immune response already.”
Analyses of COVID-19 vaccine trials show few adverse effects — defined as any health problem that happens after a shot — separate from the less serious side effects were reported. Swollen lymph nodes (lymphadenopathy) occurred in a small portion of the participant population. And four people who received Pfizer’s vaccine and three who received Moderna’s developed Bell’s palsy, which, in most cases, causes temporary weakness or paralysis in the face. https://www.aarp.org/health/conditions-treatments/info-2020/coronavirus-vaccine-side-effects.html
Dear Dr Sami Ur Rahman , I completely agree with Dr Arvind Singh . The information provided by Dr Arvind Singh is quite useful in understanding the side-effects of covid-19 vaccines. Warm regards Yoganandan G
The CDC has said COVID-19 vaccines can cause side effects for a few days that include fever, chills, headache, swelling or tiredness, “which are normal signs that your body is building protection.” However, severe reactions are extremely rare.
When any vaccine is injected in the body for immunization, it will induce some mild reactions in the form of swelling, fever, headache, chills, fatigue, and muscle pain.
The same side effects can happen with Pfizer-BioNTech COVID-19 vaccine.
