In the United States, everyone age 5 and over is currently eligible to get a COVID-19 vaccination. CDC recommends that everyone in this group get vaccinated against COVID-19 as soon as they can.
Studies show that COVID-19 vaccines are effective at keeping people from getting COVID-19. Getting a COVID-19 vaccine will also provide strong protection against getting seriously ill even if someone does get COVID-19.
For people in certain groups, booster shots are also recommended to help protect against more infectious new variants like the Delta variant. You can find more information on the CDC website about who is currently eligible for booster shots.
- People with Certain Medical Conditions (CDC)
People with underlying health conditions can safely receive the COVID-19 vaccines authorized by the FDA. Vaccination is especially important for adults of any age with underlying medical conditions like diabetes and high blood pressure. They are at increased risk for severe illness from COVID-19. For people with moderately to severely compromised immune systems, an extra booster shot may be recommended.
Examples of individuals with compromised immune systems that are at increased risk of severe illness from COVID-19 include — but are not limited to — people:
- being treated for tumors and blood cancers;
- who have received organ transplants;
- with advanced or untreated HIV infection;
- with diseases such as DiGeorge syndrome and Wiskott-Aldrich syndrome
If you have a weakened immune system from a health condition or medications, you should talk to your doctor. They may recommend you keep taking certain precautions even after you are vaccinated to minimize the risk of infection.
People who have autoimmune conditions and who have previously had Guillain-Barre syndrome or Bell’s palsy may receive a COVID-19 vaccine.
- COVID-19 Vaccines While Pregnant or Breastfeeding (CDC)
CDC recommends COVID-19 vaccines for women who are currently pregnant, trying to get pregnant, or breastfeeding.
There is growing evidence of how safe and effective COVID-19 vaccines are during pregnancy. Data suggest that the benefits of getting vaccinated during pregnancy are greater than any known or potential risks. Pregnant and recently pregnant people are more likely to get severe illness from COVID-19 than non-pregnant people - making vaccination even more important for these groups.
There is currently no evidence that COVID-19 vaccines or any other vaccines cause fertility problems in women or men.
- More on long term effects of COVID-19 (CDC)
CDC recommends that teenagers and young adults in the United States get vaccinated against COVID-19 as soon as they can. Studies show that vaccines are effective at keeping people from getting COVID-19. Even if you do get sick, studies suggest that being vaccinated helps keep you from getting seriously ill and also reduces how long you might be able to spread the virus to others.
Although most people who catch COVID-19 get better within weeks or months, some do not. CDC and health experts are learning more about short- and long-term health effects of COVID-19, who gets them, and why. People with “long COVID” report different types of symptoms. These include trouble focusing or "brain fog", memory loss, fatigue, headaches, shortness of breath, and loss of smell or taste.
- Benefits of getting a COVID-19 vaccine (CDC)
Yes, health experts recommend getting vaccinated whether or not you have already had COVID-19. At this time, experts are still learning how long you are protected from getting sick again after recovering from COVID-19. Even if you have already recovered from COVID-19, it is possible, but rare, that you could be infected with the virus that causes COVID-19 again. If you’ve had COVID-19 in the past 90 days, talk to your doctor about when you should get vaccinated.
While people who’ve already been infected may have some form of natural immunity, studies suggest that immune protection offered by vaccines is more consistent and generates a stronger antibody response.
- Selected Adverse Events Reported after COVID-19 Vaccination (CDC)
The FDA and CDC are monitoring reports of Guillain-Barré syndrome (GBS) after the Johnson and Johnson vaccine. Such cases have not been reported after the Pfizer or Moderna mRNA vaccines.
GBS is a very rare disorder where the body’s immune system damages nerve cells, causing muscle weakness and sometimes paralysis. More than 12 million doses of Johnson and Johnson have been given, with around 100 initial reports of GBS. These cases have largely been reported about 2 weeks after vaccination and mostly in men, many 50 years and older. Public health experts will continue to evaluate reports of GBS after the Johnson and Johnson vaccination.
You should seek medical attention right away if you develop any of the following symptoms after getting the Johnson and Johnson vaccine:
- A weakness or tingling sensation, especially in the legs or arms, that’s worsening and spreading to other parts of the body
- Difficulty walking
- Difficulty with facial movements, including speaking, chewing, or swallowing
- Double vision or inability to move eyes
- Difficulty with bladder control or bowel function
