COVID-19 vaccination information COVID-19 vaccine availability Following guidance from the CDC, the first phase of vaccines will be made available to healthcare personnel, essential workers and people who are over 65 or have pre-existing conditions that potentially create greater risk. The initial vaccine rollout will be focused on healthcare personnel and will then expand from there. For now, it is too early in the process to know when more vaccines will be approved or when we may have additional guidance on when vaccines will be available to our patients and community. View our frequently asked questions about vaccination for COVID-19. Vaccines offer protection How can vaccines help protect me and my loved ones? Immunization helps save millions of lives every year. Whereas most medicines treat or cure diseases, vaccines can help prevent them by working with your body’s natural defenses to build protection. When you receive a vaccine, your immune system responds. We now have vaccines to prevent more than 20 life-threatening diseases, helping people of all ages live longer, healthier lives. The World Health Organization (WHO) estimates that globally, immunization currently prevents between 2 and 3 million deaths every year from diseases like diphtheria, tetanus, pertussis, influenza and measles. Benefits of Getting a COVID-19 Vaccine Below is a summary of the benefits of COVID-19 vaccination based on what we currently know. COVID-19 vaccination will help keep you from getting COVID-19 COVID-19 vaccines are being carefully evaluated in clinical trials and will be authorized or approved only if they make it substantially less likely you’ll get COVID-19. Based on what we know about vaccines for other diseases, experts believe that getting a COVID-19 vaccine may help keep you from getting seriously ill even if you do get COVID-19. Getting vaccinated yourself may also protect people around you, particularly people at increased risk for severe illness from COVID-19. Experts continue to conduct more studies about the effect of COVID-19 vaccination on severity of illness from COVID-19, as well as its ability to keep people from spreading the virus that causes COVID-19. COVID-19 vaccination will be a safer way to help build protection COVID-19 can have serious, life-threatening complications, and there is no way to know how COVID-19 will affect you. And if you get sick, you could spread the disease to friends, family, and others around you. Clinical trials of COVID-19 vaccines must first show they are safe and effective before any vaccine can be authorized or approved for use. The known and potential benefits of a COVID-19 vaccine must outweigh the known and potential risks of the vaccine for use under what is known as an Emergency Use Authorization (EUA). Watch a video on what an EUA is. Getting COVID-19 may offer some natural protection, known as immunity. But experts don’t know how long this protection lasts, and the risk of severe illness and death from COVID-19 far outweighs any benefits of natural immunity. COVID-19 vaccination will help protect you by creating an antibody response without having to experience sickness. Both natural immunity and immunity produced by a vaccine are important aspects of COVID-19 that experts are trying to learn more about, and CDC will keep the public informed as new evidence becomes available. Ensuring the safety of COVID-19 vaccines in the United States The U.S. vaccine safety system ensures that all vaccines are as safe as possible. Safety is a top priority while federal partners work to make a coronavirus disease 2019 (COVID-19) vaccine(s) available. The Food and Drug Administration (FDA) carefully reviews all safety data from clinical trials and authorizes emergency vaccine use only when the expected benefits outweigh potential risks. The Advisory Committee on Immunization Practices (ACIP) reviews all safety data before recommending any COVID-19 vaccine for use. FDA and CDC will continue to monitor the safety of COVID-19 vaccines, to make sure even very rare side effects are identified. Getting vaccinated How many shots of COVID-19 vaccine will be needed? All but one of the COVID-19 vaccines currently in Phase 3 clinical trials in the United States need two shots to be effective. The other COVID-19 vaccine uses one shot. Are there side effects from the vaccine? After a vaccine is authorized or approved for use, many vaccine safety monitoring systems watch for adverse events (possible side effects). This continued monitoring can pick up on adverse events that may not have been seen in clinical trials. If an unexpected adverse event is seen, experts quickly study it further to assess whether it is a true safety concern. Experts then decide whether changes are needed in U.S. vaccine recommendations. This monitoring is critical to help ensure that the benefits continue to outweigh the risks for people who receive vaccines. If I have already gotten sick with COVID-19, do I still need to get vaccinated with a COVID-19 vaccine when it’s available? Due to the severe health risks associated with COVID-19 and the fact that re-infection with COVID-19 is possible, people may be advised to get a COVID-19 vaccine even if they have been sick with COVID-19 before. At this time, experts do not know how long someone is protected from getting sick again after recovering from COVID-19. The immunity someone gains from having an infection, called natural immunity, varies from person to person. Some early evidence suggests natural immunity may not last very long. We won’t know how long immunity produced by vaccination lasts until we have a vaccine and more data on how well it works. Both natural immunity and vaccine-induced immunity are important aspects of COVID-19 that experts are trying to learn more about, and CDC will keep the public informed as new evidence becomes available. Why would a vaccine be needed if we can do other things like social distancing and wearing masks, to prevent the virus that causes COVID-19 from spreading? Stopping a pandemic requires using all the tools available. Vaccines work with your immune system so your body will be ready to fight the virus if you are exposed. Other steps, like covering your mouth and nose with a mask and staying at least 6 feet away from others, help reduce your chance of being exposed to the virus or spreading it to others. Together, COVID-19 vaccination and following CDC’s recommendations to protect yourself and others will offer the best protection from COVID-19. Do I need to wear a mask and avoid close contact with others if I have received two doses of the vaccine? Yes. While experts learn more about the protection that COVID-19 vaccines provide under real-life conditions, it will be important for everyone to continue using all the tools available to us to help stop this pandemic, like covering your mouth and nose with a mask, washing hands often, and staying at least 6 feet away from others. Together, COVID-19 vaccination and following CDC’s recommendations for how to protect yourself and others will offer the best protection from getting and spreading COVID-19. Experts need to understand more about the protection that COVID-19 vaccines provide before deciding to change recommendations on steps everyone should take to slow the spread of the virus that causes COVID-19. Other factors, including how many people get vaccinated and how the virus is spreading in communities, will also affect this decision. When can I stop wearing a mask and avoiding close contact with others after I have been vaccinated? There is not enough information currently available to say if or when CDC will stop recommending that people wear masks and avoid close contact with others to help prevent the spread of the virus that causes COVID-19. Experts need to understand more about the protection that COVID-19 vaccines provide before making that decision. Other factors, including how many people get vaccinated and how the virus is spreading in communities, will also affect this decision. Should I be vaccinated if I am pregnant or breastfeeding? Currently, there are no data on the safety and efficacy of COVID-19 vaccines in women who are pregnant or breastfeeding to inform vaccine recommendations. Further considerations around use of COVID-19 vaccines in pregnant or breastfeeding HCP will be provided once data from phase III clinical trials and conditions of FDA Emergency Use Authorization are reviewed. Does immunity after getting COVID-19 last longer than protection from COVID-19 vaccines? The protection someone gains from having an infection (called natural immunity) varies depending on the disease, and it varies from person to person. Since this virus is new, we don’t know how long natural immunity might last. Some early evidence — based on some people — seems to suggest that natural immunity may not last very long. Regarding vaccination, we won’t know how long immunity lasts until we have a vaccine and more data on how well it works. Both natural immunity and vaccine-induced immunity are important aspects of COVID-19 that experts are trying to learn more about, and CDC will keep the public informed as new evidence becomes available.
