Getting the COVID-19 Vaccine

Is the COVID-19 Vaccine Safe?


Yes. COVID-19 vaccines being used in the U.S. have met the FDA's rigorous health standards for safety and effectiveness and have been rigorously tested amongst all populations. Millions of Americans have already received the COVID-19 vaccines without experiencing any serious side effects, and all COVID-19 vaccines will continue to be intensely monitored for safety.


Are COVID-19 vaccines effective? Do they work?


Yes. In clinical trials, authorized vaccines were nearly 100% effective in preventing hospitalization and deaths from COVID-19.


I am worried these vaccines were developed too fast. Were corners cut?


More than twenty years of research and study led to the development of our safe and highly effective vaccines that are already protecting millions of people deadly COVID-19 virus that has claimed the lives of nearly 600,000 Americans. Tens of thousands of volunteers participated in clinical trials that enabled rapid accumulation of data on safety and effectiveness. This is more participants than any vaccine trial before.


Are there side effects


Side effects such as chills or tiredness may affect your ability to do daily activities, and will go away in a few days. These side effects after vaccination are normal as they are signs that your body is building protection.


If I’ve already recovered from COVID-19 infection, do I need to be vaccinated?


Yes, you should be vaccinated regardless of whether you already had COVID-19. A COVID-19 vaccine will protect you from being infected again, which is possible—although rare—if you are unvaccinated.


What is an Emergency Use Authorization?


Drugs and vaccines have to be approved by the Food and Drug Administration (FDA) to ensure that only safe and effective products are available to the American public. During public health emergencies, when there is good scientific reason to believe that a product is safe and is likely to treat or prevent disease, the FDA may authorize its use through an Emergency Use Authorization (EUA), even if definitive proof of the effectiveness of the drug or vaccine is not known.

FDA pre-licensure approval is considered for treatment or prevention of diseases that are very serious.


What kind of information will be available to me before I receive the vaccine?


Each potential recipient of COVID-19 vaccine will receive a vaccine-specific Fact Sheet for Recipients from the FDA, which will provide the following information:

  • Basic information on COVID-19, symptoms, and what to discuss with a health care provider before vaccination
  • Who should and should not receive the vaccine
  • That recipients have the choice to receive the vaccine
  • Dosage and vaccine series information
  • Risks and benefits of the vaccine
  • If offered under an EUA, an explanation of what an EUA is and why it is issued
  • Any approved available alternatives for preventing COVID-19
  • Additional resources


How will I be able to keep track of what vaccine I got and when I need to get a second dose?


All vaccine recipients will be provided a copy of the CDC COVID-19 Vaccination Record Card after receipt of the vaccine. It is recommended that the second-dose appointment be made at the time of initial vaccinations, or instructions provided on procedures for second dose follow-up. If a vaccine recipient has a smartphone, it is recommended that they take a photo of the vaccination record card as a back-up copy and set a calendar reminder for receipt of the second dose.


Will the DOD provide vaccines for civilian employees and contractor staff working in military hospitals or clinics?


The DOD is offering the vaccine to civilian and contractor staff with direct patient care and to those who normally receive vaccine for occupational health purposes, as authorized in accordance with DOD regulation.


Where can I get the vaccine?


You can get the vaccine anywhere its available. All eligible and authorized TRICARE beneficiaries can make a COVID-19 vaccine appointment, as available, at a DOD vaccination site. The availability of the vaccine may vary by location. To find a vaccine location near you, visit

If you get the vaccine from a non-DOD provider, please remember to update your medical record.


How long will protection last following vaccination?


We don’t know how long protection will last following vaccination but it will be critically important to measure long-term protection (at least two years) in the phase 3 trials and in other groups prioritized for early vaccination. We are still learning about the duration of protection following infection with COVID-19 and it is too early to tell how long protection will last.


Can someone get COVID-19 from the vaccine?


No, it’s not possible to get COVID-19 from vaccines. Vaccines against COVID-19 use inactivated virus, parts of the virus, or a gene from the virus. None of these can cause COVID-19.


Should I get the vaccine for influenza (flu shot)?


Yes, it is very important to get the influenza vaccine, particularly this season when both influenza viruses and COVID-19 will infect people.
