Stay up to date with COVID-19 vaccines, including reminders

Meta description


What do you want to know

  • The CDC recommends that everyone stay up to date with the COVID-19 vaccination, including all primary series doses and boosters for their age group:
    • The ages of people 6 months to 4 years should receive all doses of the primary COVID-19 series.
    • The ages of people 5 years and over should receive all doses in the primary series and the booster dose recommended for them by the CDC, if eligible.
      • The ages of people 5 years to 11 years are currently recommended to obtain the original booster (monovalent).
      • The ages of people 12 years and over are recommended to receive one booster Pfizer or Moderna (bivalent) updated.
        • This includes people who have received all doses of the primary series and people who have already received one or more original (monovalent) boosters.
        • At that time, the elderly 12 to 17 years old can only receive the Updated Pfizer bivalent recall.
  • Getting vaccinated against COVID-19 after recovering from a COVID-19 infection provides additional protection against COVID-19.
  • Moderately or severely immunocompromised people have different recommendations for COVID-19 vaccines, including boosters.
  • COVID-19 vaccine and booster recommendations may be updated as the CDC continues to monitor the latest data.

About COVID-19 vaccines

The COVID-19 vaccines available in the United States are effective in preventing people from becoming seriously ill, being hospitalized and dying. As with other illnesses, you are best protected against COVID-19 when you stay up to date with recommended vaccines, including recommended boosters.

Four COVID-19 vaccines are approved or licensed in the United States to prevent COVID-19: Pfizer-BioNTech, Moderna, Novavax, and Johnson & Johnson’s Janssen (J&J/Janssen). It is recommended that the J&J/Janssen COVID-19 vaccine be considered only in certain situations.

Updated COVID-19 boosters can both help restore protection that has waned since the previous vaccination and provide broader protection against newer variants. Updated, or bivalent, boosters target the newer Omicron subvariants, BA.4 and BA.5, which are more contagious and resistant than earlier Omicron strains.

When are you up to date?

You are up to date with your COVID-19 vaccines if you have completed a primary series of COVID-19 vaccines and received the most recent booster dose recommended for you by the CDC.

Vaccine recommendations are based on your age, the vaccine you first received, and the time since the last dose. Moderately or severely immunocompromised people have different recommendations for COVID-19 vaccines.

Children and teenagers from 6 months to 17 years old

The dosage of the COVID-19 vaccine is based on age on the day of vaccination, not height or weight. Children receive a smaller dose of COVID-19 vaccine than adolescents and adults depending on the age group they belong to.

Adults 18 and over

1 Talk to your healthcare or vaccine provider about the timing of the 2nd dose of your primary series.

  • People aged 6 months to 64 years, and particularly men aged 12 to 39may consider receiving the 2nd primary dose of a COVID-19 mRNA vaccine (Pfizer-BioNTech or Moderna) 8 weeks after the 1st dose.
    • A longer delay between the 1st and 2nd primary dose may increase the degree of protection offered by vaccines and further minimize the rare risk of myocarditis and pericarditis.
  • Anyone wishing to be protected due to high levels of community transmission, ppeople aged 65 and over, or people who are more likely to become seriously ill from COVID-19, should receive the second dose of:
    • Pfizer-BioNTech Covid-19 vaccine 3 weeks (or 21 days) after the first dose.
    • Modern Covid-19 vaccine 4 weeks (or 28 days) after the first dose.
    • Novavax Covid-19 vaccine 3 weeks (or 21 days) after the first dose.

2 If you have completed your main streak, but are not yet eligible for a booster, you are also considered current.
