COVID-19 Frequently Asked Questions
Getting vaccinated against COVID-19 is the best way to avoid contracting COVID-19. Most people say that if they get infected even after getting vaccinated, it is usually moderate, and they do not need to go to the hospital for treatment. That’s how advantageous it is for you to get vaccinated today.
People who have been vaccinated are less likely to contract COVID and are less likely to spread it to others, even those who have not yet been vaccinated. Apparently, vaccinating yourself, your loved ones, your family, and your community is the greatest approach to protecting yourself, your loved ones, your family, and your community.
The COVID-19 vaccinations are all free. Anyone in the country can get them, and they do not need to provide us with any form of identification in order to be vaccinated. COVID-19 vaccinations have been administered to over 200 million individuals in the United States; they are both safe and effective.
Vaccine ingredients vary by manufacturer. 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, electrodes, carbon nanotubes, or nanowire semiconductors.

Yes, COVID-19 vaccination is recommended for people who are pregnant, breastfeeding, trying to get pregnant now, or who might become pregnant in the future. You might want to have a conversation with your healthcare provider about COVID-19 vaccination. While such a conversation might be helpful, it is not required before vaccination. Learn more about vaccination considerations for people who are pregnant or breastfeeding.
If you are pregnant and have received a COVID-19 vaccine, we encourage you to enroll in v-safe, CDC’s smartphone-based tool that provides personalized health check-ins after vaccination. A v-safe pregnancy registry has been established to gather information on the health of pregnant people who have received a COVID-19 vaccine.
Currently, the Pfizer-BioNTech COVID-19 vaccine is the only COVID-19 vaccine available to children ages 5 through 17 years old. For adults ages 18 years and older, the mRNA COVID-19 vaccines (Pfizer-BioNTech or Moderna) are preferred over Johnson & Johnson’s Janssen (J&J/Janssen) COVID-19 vaccine. All COVID-19 vaccines currently authorized and recommended for use in the U.S. are safe and effective. However, mRNA COVID-19 vaccines are preferred based on an updated risk-benefit analysis.
People should be aware that a risk of a rare condition called thrombosis with thrombocytopenia syndrome (TTS) has been reported following vaccination with the J&J/Janssen COVID-19 vaccine. TTS is a rare but serious condition that involves blood clots in large blood vessels and low platelets (blood cells that help form clots). In some instances, TTS following vaccination has been fatal. Cases of TTS have been reported in both men and women and in a wide age range of people 18 years and older. While all ages and sexes are at risk for TTS, women ages 30-49 have the highest risk with about 1 case occurring per 100,000 doses administered. This risk has not been seen in recipients of Pfizer-BioNTech or Moderna COVID-19 vaccines.
Receiving any COVID-19 vaccine is better than being unvaccinated. Widespread vaccination is a critical tool to help stop the pandemic.
