Building confidence in the COVID-19 vaccine
Basics of the COVID-19 vaccine
- The COVID-19 vaccine is provided at no cost to the public regardless of immigration or insurance status
- The vaccine protects against COVID-19 and reduces the chances of hospitalizations or death. Even if you had COVID-19, you should still get vaccinated.
- Because none of the authorized COVID-19 vaccines in the United States contain the live virus that causes COVID-19, the vaccine cannot make you sick with COVID-19.
- Nearly all the ingredients in COVID-19 vaccines are also ingredients in many foods – fats, sugars, and salts
- The COVID-19 vaccine, including the doses for children ages 5 and older, has undergone thorough evaluations by both FDA and CDC. COVID-19 vaccines have and will continue to undergo the most intensive safety monitoring in U.S. history.
TYPES OF THE COVID-19 VACCINES
|Pfizer (Comirnaty) Vaccine||Janssen (Johnson & Johnson) Vaccine|
|94% effective in preventing illness|
Boosters available to individuals 5 and older:
Boosters available to individuals 18 and older:
Studies show that, after getting vaccinated, protection against the virus may decrease over time due to changes in the virus. This is why booster doses are recommended. The number of primary or booster doses recommended for you may be different from someone else based on things like age and underlying conditions. Please talk to your doctor if you are not sure about booster doses.
What to expect: Safety and side effects
There is a difference between side effects and adverse events.
A side effect is an expected response to the vaccine. These are normal signs that your body is building protection. These side effects may affect your ability to do daily activities, but they should go away in a few days.
Common side effects from the COVID-19 vaccine:

An adverse event is a very rare and an unexpected response. Adverse effects that could cause a long-term health problem are extremely unusual following vaccination. If adverse effects occur, they generally happen within six weeks of receiving a vaccine dose. For this reason, during clinical trials, the U.S. Food and Drug Administration (FDA) collected data on each of the authorized COVID-19 vaccines for a minimum of two months (eight weeks) after the final dose. CDC, FDA, and other federal agencies continue to monitor the safety of COVID-19 vaccines even now that the vaccines are in use.
Common Questions, Myths and facts about the vaccine
Are COVID-19 vaccines safe even though they were developed rapidly?
Scientists have been working for many years to develop vaccines against viruses like the one that causes COVID-19. This knowledge helped speed up the initial development. All vaccines in the U.S. must go through three phases of clinical trials to make sure they are safe and effective. During the development of COVID-19 vaccines, phases overlapped to speed up the process, but all phases were completed.
What are the ingredients in COVID-19 vaccines?
Vaccine ingredients vary by manufacturer and the lists are open to the public. None of the vaccines contain eggs, gelatin, latex, or preservatives. All COVID-19 vaccines are free from metals such as iron, nickel, cobalt, lithium, and rare earth alloys. They are also free from manufactured products such as microelectronics and electrodes.
If I have already had COVID-19 and recovered, do I still need to get vaccinated?
Yes. Research has not yet shown how long you are protected from getting COVID-19 again after you recover from COVID-19. Vaccination helps protect you even if you’ve already had COVID-19. One study showed that unvaccinated people who already had COVID-19 are more than 2 times as likely than fully vaccinated people to get it again.
