And a wet, cool towel at the injection site can help, too. Taking Tylenol or Advil or other pain killers before the administration of a dose may hamper the immune response the vaccine is made to elicit. The CDC recommends that you use over-the-counter pain killers and standard medication to deal with these lower-grade symptoms or pain, but only after receiving your shot. For some, the reactions to a second dose of the Pfizer or Moderna vaccine may last longer and be more severe. In essence, effects which resemble flu-like symptoms but tend to subside pretty quickly. For instance, for several hours or several days after receiving your first or second dose of the Pfizer or Moderna shots, or the single dose of the Johnson & Johnson vaccine, you may experience some fatigue, feel loopy, have a headache, experience muscle aches throughout various parts of your body, have chills, fever, or nausea. According to the CDC, the most common side effects from the currently authorized COVID vaccines are: arm pain at the injection site or throughout the arm where the shot was administered swelling on the administration arm redness fatigue headache and dizziness.īut then things can get strange for other parts of your body. Some people have no side effects,” writes the agency. These side effects may affect your ability to do daily activities, but they should go away in a few days. “You may have some side effects, which are normal signs that your body is building protection. The good news is, for the vast majority of people, side effects appear to be relatively mild and last anywhere from hours to a couple of days. “Anaphylaxis after COVID-19 vaccination is rare and occurred in approximately two to five people per million vaccinated in the United States,” the Centers for Disease Control (CDC) notes. That’s also why after a vaccine is administered, your vaccination site will require you to stick around for at least 15 minutes to see if you suffer from severe side effects (and up to a half hour if you have a history of anaphylaxis). They all appear to present similar side effects and higher risks for a very rare group of people in general, according to available data.įor instance, the vaccines can lead to dangerous conditions such as anaphylaxis in a small portion of the population.
There are instances wherein certain people may have severe reactions to the COVID vaccines from Pfizer/BioNTech, Moderna, and Johnson & Johnson. It’s important to note that, whatever side effects you may or may not feel from a given COVID vaccine, it’s still significantly preferable to severe illness, hospitalization, death, or passing the coronavirus on to more vulnerable people. What are the most common COVID vaccine side effects? Just what side effects may you experience? Here’s what we know about everything from the strange to the mundane adverse events. And it takes time to learn exactly what those are and who it affects. So when vaccines like the currently FDA-authorized shots such as Pfizer/BioNTech’s, Moderna’s, and Johnson & Johnson’s for COVID-19 are developed in about a year rather than the upwards of 10 years many vaccines take to develop, it isn’t surprising that you may run into some common, and not-so-common, side effects. And that comes with a bit of unpredictability since human biology tends to vary. At a base level, they’re a way to trick your body into building up defenses against threats that haven’t necessarily penetrated your biology yet. Vaccines are pretty weird if you really think about it.
