Frequently Asked Questions
For general information regarding the COVID-19 vaccines, please see a full list of COVID-19 vaccine FAQs on our Vaccine Information page.
How do I know a vaccine is safe?
The FDA reviews all vaccines for safety before allowing them onto the market. In New York State, the Governor’s Clinical Advisory Task Force will also offer an independent opinion about each vaccine’s safety and efficacy. This Task Force, which includes highly respected scientists like Adolfo García-Sastre, PhD, Irene and Dr. Arthur M. Fishberg Professor of Medicine at the Icahn School of Medicine at Mount Sinai, reviewed the data independently and recommended approval of the Pfizer vaccine on Thursday, December 10, and the Moderna vaccine on Friday, December 18.
Will taking the vaccine give me COVID-19?
No. It is NOT possible to get COVID-19 from the vaccines made by Pfizer or Moderna, or any of the other vaccines in advanced clinical trials
Are we taking the federal government’s word that a vaccine is safe?
No. The Advisory Committee for Immunization Practices (ACIP), a group of medical and public health experts that advises the Centers for Disease Control and Prevention (CDC), also assesses the safety and efficacy of vaccines. They will also develop recommendations on COVID-19 vaccine use.
Additionally, in New York State, the Governor’s Clinical Advisory Task Force will independently review the vaccines as they are made available. According to the Governor’s plan, “The Task Force’s independent review of any federally authorized COVID-19 vaccine will help address publicly reported concerns about the scientific process and rush to market. The Task Force will rely on numerous data sources including public information and the findings of expert third party independent organizations.”
What Is an Emergency Use Authorization?
In the United States, vaccines must be approved by the Food and Drug Administration (FDA) before they can be used. The FDA bases its decision on data from clinical trials. In a clinical trial, the vaccine is given to volunteers—sometimes tens of thousands of them—while others get a placebo, meaning an injection that doesn’t contain any vaccine. Scientists observe whether the people who got the vaccine get fewer cases of the disease than those who got the placebo. This means that the vaccine appears to work in those people; this is called the vaccine’s “efficacy.” The scientists also watch out for unexpected side effects that the vaccine might have caused. This is called the vaccine’s “safety.”
If the clinical trial data shows enough evidence of efficacy and safety, the FDA will approve the vaccine and license it for use in the United States.
Sometimes, the FDA will allow a medical product that has not yet been fully approved to be used in an emergency to diagnose, treat, or prevent a serious illness. This is called “emergency use authorization” or “EUA”.
An EUA may be issued when the FDA determines that the product “may be effective” against the disease based on all the available scientific evidence. This is a lower standard than required for full approval of a product; it uses early data gathered from clinical trials.
More information on EUAs is available from the FDA website.
What do we know about side effects of the first vaccines?
Like all vaccines, the Pfizer and Moderna COVID-19 vaccines can cause side effects. These rarely interfere with daily activities, and often go away with over-the-counter pain medications. It is common to have these types of side effects after a vaccination. They mean your immune system is working and making antibodies as it’s supposed to.
The following side effects to the Pfizer vaccine are very common, meaning that they may affect more than 1 in 10 people:
-
Pain at injection site
-
Tiredness
-
Headache
-
Muscle pain
-
Chills
-
Joint pain
-
Fever
Other side effects, like enlarged lymph nodes, were uncommon, affecting up to 1 in 100 people.
Common side effects of the Moderna vaccine include injection site pain, fatigue, headache, muscle pain, joint pain, and chills. These side effects were generally short-lived and more common after the second dose.
These are not all the possible side effects you may have when taking the vaccine. If you experience any side effects not listed here, tell your health care professional.
Should I take the vaccine if I am pregnant or considering pregnancy, or if I am breastfeeding?
Pregnant and breastfeeding persons and those who are considering pregnancy are encouraged to speak to their health care providers about the potential benefit of vaccination, especially if they are a health care worker or an essential worker, or have underlying medical conditions.
Should I take the vaccine if I have severe allergies?
Do not get the Pfizer or Moderna COVID-19 vaccine if you have had a severe allergic reaction (i.e., anaphylaxis) to vaccines or the components of that vaccine. If you have a history of severe medication allergies, please discuss with your health care provider.
Do the clinical trials for COVID-19 vaccines include people from the most affected groups?
Yes.
While vaccines work the same in people of different races or ethnicities, it is important to make sure vaccines are tested in diverse population groups before they are released. The phase 3 clinical trials conducted by Pfizer and Moderna included significant numbers of participants from the population groups most at risk for COVID-19.
In Pfizer’s U.S. trial, 13.1 percent of participants are Hispanic/Latinx, 10.1 percent are Black, 5.5 percent are Asian American, and 1 percent are Native American. About 45 percent of U.S. participants are 56-85 years of age.
For comparison, in the most recent estimates by the U.S. Census Bureau, 18.4 percent are Hispanic/Latinx, 12.8 percent are Black, 5.7 percent are Asian American, and 0.9 percent are Native American. The Census uses slightly different age groups than the drug companies, but says that 27.4 percent of Americans are between ages 55 and 84.
Of the patients in Moderna’s trial, 9.7 percent identified as Black or African American, 20 percent as Hispanic/Latinx, 4.7 percent as Asian, and 0.8 percent as Native American. Also, 25.3 percent were over the age of 65 (compared to 16.5 percent in the general population), and 22.3 percent had at least one high-risk chronic disease, such as diabetes, severe obesity, and cardiac disease.
