Based on the results of several large clinical trials and on the safety monitoring from the millions of people who have already received vaccines against COVID-19, the vaccines have been demonstrated to be generally well-tolerated when used under the conditions established in their labeling. For those who experience side effects, the most common side effects are usually mild and go away on their own. These common side effects are things like headache, mild fever, tiredness, joint pain, chills, and soreness at the injection site. Severe side effects like anaphylaxis (severe potentially life-threatening allergic reaction) are rare but do occur. Signs of a severe allergic reaction can include difficulty breathing, swelling of your face and throat, a fast heartbeat, a bad rash all over your body and/or dizziness and weakness. In addition, pericarditis (inflammation of the outer lining of the heart), or myocarditis (inflammation of the heart muscle) have occurred in some people who have received the vaccine. You should seek medical attention right away if you have any of the following symptoms after receiving the vaccine: chest pain, shortness of breath, feeling of having a fast-beating, fluttering, or pounding heart.
MYTH: Natural immunity is better than vaccine immunity.
FACT: Compared to immunity following infection, vaccines offer stronger, more specific, and longer-lasting immunity against SARS-CoV-2 infection and COVID-19 illness.
While people can get some protection from having COVID-19, the level and length of that protection varies. Vaccination, on the other hand, has been known to lead to a more consistent, longer-lasting, and stronger antibody response. Vaccine-based immune response can also be increased with booster shots when needed.
