Why did the COVID-19 vaccines get approved so quickly?

The Food and Drug Administration (FDA) carefully reviews all safety data from clinical trials and authorizes an emergency vaccine only when the expected benefits outweigh potential risks.

How were the vaccines evaluated?

The safety and efficacy of the vaccines were reviewed by panels of independent experts.

There are no reported serious safety concerns from the Pfizer and Moderna vaccines.

The CDC and the FDA will continue to monitor individuals who have received the vaccines to ensure there’s no evidence of even rare safety issues.

How do we know the COVID vaccines are safe?

Many people are concerned about vaccine safety because of how quickly the vaccines have been developed. In an emergency like a pandemic, the FDA can make a judgment that it’s worth releasing something for use, even without the typical timeline for a new vaccine or drug.

The Emergency Use Authorization (EUA) issued was based on evidence that strongly suggests patients have benefited from the vaccine in clinical trials.

Current data from the manufacturers for both vaccines strongly indicate they are safe and effective. You can read more about the benefits of being vaccinated. These vaccines will continue to be studied, as is true with all vaccines.

What if I'm immunocompromised?

Vaccination is a personal decision. If you are immunocompromised or have concerns about vaccine side effects, make an appointment to discuss these concerns with your health care provider. The CDC has more information available for people who are immunocompromised.

What if I'm pregnant? Do I still get vaccinated?

Pregnant patients may be vaccinated, but it's important to talk with your provider to help you decide whether vaccination is right for you. Vaccination for disease such as COVID-19, which has been authorized for use under Emergency Use Authorization (EUA), often demonstrates greater benefit than risk. Here is more information on COVID-19 vaccination and pregnancy and breastfeeding.

What are the COVID-19 vaccination side effects?

As with any vaccination, side effects vary. Some people may have some; others none at all. Here is what you need to know:

  • The immunization process can cause minor symptoms. This is normal.
  • Both Pfizer and Moderna reported side effects as mild to moderate.
  • Shots may cause mild flu-like effects, including sore arms, muscle aches and fever.
  • You will be monitored for 15 minutes after your vaccination.

Can I be vaccinated if I have my mammogram scheduled?

COVID-19 vaccines may lead to temporary swelling in the lymph nodes, which may make your breast screening study difficult to interpret. If you are scheduled for a routine screening mammogram or breast MRI, schedule your screening before you receive your first dose or wait until four to six weeks after receiving your second dose. If you are scheduled for a diagnostic mammogram, keep your regularly scheduled appointment.

Do not delay preventive screening further. The earlier breast cancer is found, the greater the chance for better outcomes. If you have questions or concerns, talk with your health care provider about what is best for you.

Can I get COVID from being vaccinated?

You cannot get COVID-19 from being vaccinated. The vaccines being produced in the United States contain no live virus. Research continues regarding vaccination and antibody testing. Get the COVID-19 facts from the CDC.
