Frequently Asked Questions About COVID-19 Clinical Studies



A: There is no licensed vaccine or antibody against severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), which is the virus that causes coronavirus disease 2019 (COVID-19). Scientists are working very hard to develop a vaccine and an antibody and do the research to determine whether they are safe and effective against SARS-CoV-2.

A: No. That type of study design is known as a challenge study. Instead, we are using a design known as “randomized, blinded, placebo-controlled” studies. We will enroll people who are more likely to be exposed to SARS-CoV-2 infection and COVID-19 illness. Some participants will get the vaccine, and some will get a placebo, which is a sterile saline solution that does not have any vaccine in it. We expect that some people will be exposed to the virus in their everyday lives, and may become sick. We will compare the 2 groups to see if there are fewer people who get sick in the vaccine group than in the placebo group. This is how we will know if the vaccine works.

A: Unlike guinea pigs, people can say yes or no about joining a study. All study volunteers must go through a process called informed consent that ensures they understand all of the risks and benefits of being in a study, and those volunteers are reminded that they may leave a study at any time without losing any of their rights or benefits. The COVID-19 Prevention Network (CoVPN) takes great care to make sure people understand the study fully before they decide whether or not to join. All CoVPN studies follow US federal regulations on research, as well as international ethical standards and any country-specific requirements for the countries where our research is conducted.

A: In order to find a vaccine or antibody that works in all kinds of people, it is necessary to test them in all kinds of people. This is especially true for groups of people that have been hardest hit by the COVID-19 pandemic. Protecting the well-being of study volunteers is the greatest responsibility in every study, and the CoVPN works to make sure that our studies follow the highest ethical standards. These studies are done in collaboration with local scientists and researchers and community representatives with oversight by ethics and regulatory groups in each country. Many studies are done in sub-Saharan Africa, Europe, North America, and South America at the same time and we follow the same procedures and international standards no matter where the study takes place.

A: No. The vaccines and antibodies being tested by the CoVPN are preventive products. They must be tested on volunteers who do not have COVID-19, because our goal is to keep people healthy. There are other research groups that are conducting studies of treatments that might be used for people who already have COVID-19.

A: It is true that vaccines often have side effects, but those are typically temporary (like a sore arm, low fever, muscle aches and pains) and go away after a day or two. Many studies have proven that there is no link between vaccines and autism. There is also no link between childhood vaccination and autism. The British doctor who originally published the finding about vaccines and autism has since been found to have falsified his data and was stripped of his license to practice medicine. The value of protection among vaccinated individuals and to the public has made vaccines one of the top public health measures in history, second only to having a clean water supply.

A: Yes, people who join a study get compensated for their time and inconvenience. The amount per visit varies depending on how long the visit is and the procedures that take place. The amount also varies from city to city, because the cost of living is different between large metropolitan areas compared to smaller towns and rural areas. The details about compensation will be explained when a person goes through the informed consent process at a local clinic to join a study.

A: Operation Warp Speed, a program of the US government, is working to purchase enough COVID-19 vaccines to provide universal coverage for the country. This is done in 2 ways: by buying vaccine doses now, and through an “option to purchase program.” All 5 major companies whose products are being tested in US government-funded studies are participating. This will allow the country to have enough doses for the 220 million adults and 110 million children for whom vaccines could potentially be administered.

We expect that these 5 different vaccines may have different safety profiles and/or differences in the immune responses people have to them. This could be especially true for women of childbearing age, children, and the elderly. If only a few vaccines are effective, the CDC and the US government’s ACTIV program will establish recommendations for priority populations that should receive the vaccines first. This would be temporary until the option to purchase program results in having enough vaccine doses for optimal coverage. We are confident that this approach will provide enough vaccine doses to vaccinate those in vulnerable populations to protect as many people as possible.

As part of the US government effort, it is our obligation to ensure that everyone in America is provided with a safe and effective vaccine as soon as possible. Since the vaccine will be purchased by the US government, the vaccine will be affordable for the public. We recognize that vulnerable populations in many underserved communities are among those at highest risk for suffering the consequences of COVID-19. We are committed to vigorous minority community outreach and maximizing access in these communities, including the Black/African American, Latinx and Native American populations.

A: When you have completed the submission of your survey, you will see a message with the heading “Success!” which means that we have successfully received your information. Our system does not send out an email confirmation message.

Your information will be provided to a study site closest to your location. If the study site thinks you may qualify for a particular study, they will reach out to you as soon as possible about participating. This could be soon, or it may be in several months, as there are several studies taking place over the next 6 months. We will never ask for your financial, credit, or bank account information. We will never ask for an ID number over the phone.

COVID-19 FAQs

A novel coronavirus is a new coronavirus that has not been previously identified in people. Coronavirus disease 2019 (COVID-19) is caused by the new virus called severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2). This is not the same as the coronaviruses that commonly circulate among humans and cause mild illness, like the common cold.

A: No. People of all ages can be infected by SARS-CoV-2, the virus that causes COVID-19. However, older people and people with some pre-existing health conditions are more at risk of severe illness. 1

A: COVID-19 can affect anyone, regardless of their race or ethnicity. However, data show that it is disproportionately impacting Black, Latinx, and Native American populations. This is largely due to social and structural factors that impact some communities more than others. These factors include poverty, poor housing conditions, challenges with accessing medical care, and limited resources, among others.

A: No. Antibiotics help stop bacterial infections and are not effective against viruses such as SARS-CoV-2.1

A: No. Some people who do get SARS-CoV-2, the virus that causes COVID-19, experience flu-like symptoms. COVID-19 currently has a higher death rate than the flu and appears to be more contagious than the flu.2 We do not know yet whether COVID-19 will change with the seasons like influenza. In the US, the CDC recommends that everyone aged 6 months and over receive an influenza vaccine every year.

A: Yes. Scientists have found that people who have SARS-CoV-2 and have no symptoms (i.e., asymptomatic) can still pass along SARS-CoV-2 to others.2 In fact, people infected with SARS-CoV-2 seem to be most infectious before they even show signs and symptoms.

A: The FDA is reviewing many drugs as potential treatments, but nothing has yet been approved to treat or prevent COVID-19. The FDA is also identifying treatments, such as Remdesivir, to help ease the symptoms and help people recover more quickly.3

A: Face masks can reduce your chances of getting SARS-CoV-2, but the primary purpose of face masks is to protect others from you in case you are infected, especially if you are not showing symptoms. It is recommended that the public wear cloth masks, including homemade masks, to help prevent transmitting the virus to other people.4

A: To date there is no information or evidence to suggest that SARS-CoV-2 can be transmitted by mosquitos. This disease is a respiratory virus spread primarily through droplets when an infected person coughs, sneezes or has discharge from the nose.1

A: Vaccines against other diseases do not offer protection against SARS-CoV-2. This is a new virus that will need its own vaccine, and researchers are working on developing a safe and effective one.4

A: SARS-CoV-2 can be transmitted in all areas, including hot/humid and cold climates.1

A: While gargling with warm saltwater can make a sore throat feel better, it has no effect on SARS-CoV-2.5

A: There are simple things you can do to help keep yourself and others healthy. Wash your hands often with soap and water for at least 20 seconds, especially after blowing your nose, coughing, sneezing, going to the bathroom, and before eating or preparing food.

When in public, wear a cloth face mask that covers your mouth and nose. Avoid touching your eyes, nose, and mouth with unwashed hands. Stay home when you are sick. Cover your cough or sneeze with a tissue, then throw the tissue in the trash.2 Stay 6 feet apart from other people when you are out in public.

A: No. You can help stop COVID-19 by knowing the signs and symptoms, which can include:

  • Fever
  • Cough
  • Shortness of breath
  • Chills
  • Sore throat
  • New loss of taste and/or smell

Seek medical attention immediately if you or someone you have been exposed to has emergency warning signs, including:

  • Trouble breathing
  • Persistent pain or pressure in the chest
  • New confusion or not able to be woken up (from sleep)
  • Bluish lips or face

This list of symptoms is NOT all inclusive and is being updated as new information becomes available. Please consult your medical provider for any other symptoms that are severe or concerning.2
