You may. A vaccine booster is recommended to anyone 12+ who received the Pfizer-BioNTech, Moderna or Janssen/Johnson & Johnson vaccine.
People with moderately to severely compromised immune systems are especially vulnerable to COVID-19 and may not build the same level of immunity to a two-dose vaccine series compared to people who are not immunocompromised. For these individuals, CDC recommends an additional dose of mRNA COVID-19 vaccine at least 28 days after a second dose of the Pfizer-BioNTech or Moderna COVID-19 vaccine for these individuals. People with moderately to severely compromised immune systems can also receive a booster dose 5 months after their additional dose of COVID-19 vaccine.
Speak with your healthcare provider about getting a COVID-19 booster vaccine.
For more information on booster doses visit the Centers for Disease Control and Prevention website.
SARS-CoV-2, the virus that causes COVID-19, is a type of coronavirus. Like all viruses, coronaviruses change constantly through mutation, resulting in new variants such as Omicron. The CDC closely monitors variants and has posted information about Omicron. The ways to protect yourself from coronavirus infection haven’t changed. You should be up to date on your recommended COVID-19 vaccinations, including boosters. Boosters are available for everyone 12+. Continue washing your hands and stay home when you are sick. Masking provides an additional layer of protection and CDC recommends wearing a mask in public indoor settings where community transmission is substantial or high. Until you are fully vaccinated, maintain social distance from others and wear a mask around those who do not live in your household. Remember that breakthrough infections are expected in fully vaccinated people. Vaccines are effective at preventing severe illness, hospitalization, and death.
There is no exact date. The reason COVID-19 vaccines are safe and effective is because there is a rigorous process all vaccines go through before they become widely available. You can learn more about how vaccines are approved at Lung.org/vaccines.
The American Lung Association urges members of the public to always consult with their own healthcare providers about whether this or any vaccine is appropriate for them.
