This Is When You're Most Likely to Feel Side Effects of the COVID Vaccine

According to doctors, the timeline on developing side effects usually looks like this.

The release and rollout of effective coronavirus vaccines have many of us feeling like the end of the pandemic is within sight. Fortunately, apart from a handful of isolated incidents, the shots have not produced any serious complications or symptoms outside of those you experience during traditional vaccinations. And according to experts, you can anticipate when you're most likely to feel the non-serious side effects of the COVID vaccine: after the second dose. Read on to see what you might expect after you get your shots, and for more on places that are making their own plans for distribution of doses, check out These 2 States Are Going Against the CDC's Vaccine Recommendations.

The mRNA vaccines developed by pharmaceutical companies Pfizer and Moderna work in two separate doses that are given to patients three to four weeks apart. And doctors point out that the second dose may produce more noticeable side effects in some patients.

"If you're going to get the systemic side effects, it generally occurs after the second shot when you get not only muscle aches, but you can get joint aches," David Sellers, MD, the first healthcare worker at Ascension Saint Thomas Hospital in Tennessee to receive a vaccine, told local NBC affiliate WSMV. "When you get that second injection, your body is already kind of primed and it starts reacting against the vaccine."

In fact, participants in the clinical trials for both vaccines reported more discomfort after receiving their second round of shots. But doctors note that taking a single dose only provides 50 percent efficacy, and the benefits of going for the second far outweigh missing out on the protection it provides. "The rate that you get immune to this vaccine at 93 to 94 percent is incredible," Sellers said of the second dose. "So, I want people to trust it and I want people to take it because this is a game-changer—this is the game-changer we've been waiting for, actually."

What kind of side effects could you possibly expect after getting your second shot in particular?

Similar to other inoculations, the CDC says that developing a fever is a common side effect of the COVID vaccine. The agency recommends making yourself comfortable by dressing in light clothing to bring your temperature down, as well as being sure to drink plenty of fluids. If your fever or any other side effects don't seem to be going away after a few days, the CDC says to call your healthcare provider.

The vaccine may cause you to run a fever, but it could also give you body chills. Even though the side effect creates discomfort, it's not a reason for concern unless it lasts for more than a few days, according to the CDC.

Pain and swelling in the vaccinated area

Pain, swelling, and tenderness in the arm where you receive a shot is a common side effect of many vaccines, and the COVID vaccine is no different. The CDC suggests reducing any pain by applying "a clean, cool, wet washcloth over the area" and continuing to use your arm as usual.

But keep an eye on your symptoms: while a little discomfort is nothing to worry about, the agency says you should contact your healthcare provider if the redness or tenderness in the spot you got the shot gets worse after 24 hours. The agency suggests also consulting your doctor about taking over-the-counter medications such as ibuprofen or acetaminophen if you're experiencing any significant discomfort.
