Vaccines are designed to stimulate the human body’s own protective immune response, so that if a person is infected, their immune system can recognize the infection and react to it. While vaccines are developed in different ways using different methods, it’s important to remember that they can’t give you COVID-19.

Both currently available mRNA vaccines by Pfizer and Moderna require two doses. You’ll get an initial vaccination, then a second shot — three weeks later for the Pfizer vaccine or four weeks later for the Moderna vaccine. Per the CDC, second dose shots for both can be administered up to six weeks after the first if necessary.

The second dose stimulates a greater immune response, offering the recipient far more protection from COVID-19. The appointment for your second dose will be scheduled during your first appointment at the same location.

The Janssen/J&J vaccine is administered as a single shot that provides maximum protection 14 days after administration.

The CDC states that the vaccines approved for emergency use in the United States are safe and effective. These vaccines have been tested in large, Phase 3 clinical trials and are held to the same rigorous standards as all other types of vaccines in the United States. The approved vaccines were found to be safe and effective in tens of thousands of adults who participated in Phase 3, double-blind, placebo-controlled clinical trials — widely considered the gold standard for testing pharmaceuticals.

There’s no out-of-pocket cost to you to get the COVID-19 vaccine.

Scientists anticipate that most recipients will experience mild to moderate flu-like side effects, including fatigue, chills, muscle aches and fever. These side effects should resolve in one to two days, and show your immune system is responding to the vaccine.

After you receive the vaccine, you need to remain onsite for at least 15 minutes so we can monitor you for severe allergic reactions and provide immediate treatment if needed.

According to the CDC and the U.S. FDA, if you’ve received the Janssen/J&J vaccine, watch for possible symptoms of a blood clot with low platelets. Although rare, these symptoms may develop within three weeks of receiving the vaccine and include severe headache or blurred vision, chest pain, abdominal pain, leg swelling, shortness of breath or easy bruising or blood spots under the skin by the injection site. Most people who developed these blood clots and low levels of platelets were women between ages 18 and 49. Seek medical care right away if you develop one or more of these symptoms.

According to the CDC, if you’ve had a severe allergic reaction to any ingredient in an mRNA COVID-19 vaccine, you should not get either of the currently available mRNA COVID-19 vaccines. Please see the Pfizer and Moderna Fact Sheets for ingredient lists and more information. If you had a severe allergic reaction after getting the first dose of an mRNA COVID-19 vaccine, the CDC recommends that you should not get the second dose. An evaluation and treatment by an allergist may enable you to receive the second dose.

According to Jansen/J&J, you should not receive the Janssen/J&J viral vector vaccine if you have had a severe allergic reaction to any ingredient in the vaccine. Please see the Janssen/J&J Fact Sheet for an ingredient list and more information.

Common side effects may include injection site pain, fatigue, headache, muscle pain, joint pain, nausea and fever up to 72 hours after vaccination.

However, according to the CDC, if you develop severe headache or blurred vision, chest pain, abdominal pain, leg swelling, shortness of breath or easy bruising or blood spots under the skin by the injection site within three weeks of your vaccination, seek medical care right away. If you experience sudden onset of severe symptoms, call 911 or go to the nearest emergency room.

Women younger than 50 years old should be aware of the rare but increased risk of thrombosis with thrombocytopenia syndrome (TTS). TTS is a serious condition that involves blood clots with low platelets.

Unless specifically indicated otherwise, you should be able to go ahead with most routine procedures and screenings either before or after receiving a COVID-19 vaccine. However, talk to your doctor about getting a vaccine if you’re scheduling a surgery, hospitalization or a procedure that requires anesthesia.

Please wait 4-6 weeks after vaccination to schedule your mammogram. Learn more.
