What does "Fully Vaccinated" Mean?

The CDC still considers fully vaccinated to mean two weeks after their second dose of the Moderna or Pfizer series or two weeks after the single dose Johnson and Johnson vaccine.

Updated booster rollouts to target new omicron and delta subvariants of the COVID-19 virus could soon change what it means to be “fully vaccinated.” As of October 2022, the CDC still considers fully vaccinated to mean two weeks after their second dose of the Moderna or Pfizer series or two weeks after the single dose Johnson and Johnson vaccine.

Defining Fully Vaccinated

According to the CDC and Mayo Clinic, individuals are considered fully vaccinated two weeks after the second dose of an mRNA COVID-19 vaccine (Moderna or Pfizer) administered two weeks after the second dose of the Novavax vaccine and two weeks after the single dose Johnson and Johnson vaccine. The first chart illustrates the vaccine schedule timeline for most non-immunocompromised people, and the second the timeline for immunocompromised people.

New “Up-to-Date” Vaccine Term

On September 30, 2022, the CDC published a new definition regarding what it means to be up-to-date on your covid vaccinations. According to the September report, individuals are “up-to-date” if they have received either two doses of mRNA or one dose of Johnson and Johnson and the most recent recommended booster dose.

The “up-to-date” vaccination term is part of a widespread initiative to reduce the spread of covid as we enter flu season. The goal is to protect more individuals against the highly contagious omicron variants. Recent reports have stated that the up-to-date terminology could change what is classified as “fully vaccinated”. The CDC has outlined guidelines for specific populations that should meet the up-to-date criteria. According to the CDC, individuals are considered Up-To-Date if they meet the following guidelines:

And Not Up-To-Date if they meet the following criteria:

Below are the vaccine guidelines by Age Group established by the CDC.

Vaccine Guidelines by Age Group

Age Group Vaccine Guidelines
People 6 months to 4 years old All COVID-19 primary series doses
People 5 years and older All COVID-19 primary series doses and new booster dose
People 5 to 11 years old All COVID-19 primary series doses and original booster dose
People ages 12 years and older All COVID-19 primary series doses and new Pfizer or Moderna booster
People ages 12 to 17 years old All COVID-19 primary series doses and updated Pfizer booster

Moderately and Severely immunocompromised Guidelines

Individuals classified as immunocompromised (have a weakened immune system) have an increased risk of severe COVID-19 illness. They, therefore, have a different set of guidelines for what is considered up-to-date vaccination status. According to the CDC, people are deemed immunocompromised as a result of the following conditions or treatments:

The chart below shows the covid boosters (Pfizer, Moderna, Johnson and Johnson, and Novavax) recommended for immunocompromised children ages six months to 11 years old, pre-teens, teens, and adults after they have received the initial two or one dose series.

Vaccine Guidelines by Age Group (Immunocompromised)

6 months - 4 years of age 5 years -11 years of age 12 -17 years of age 18 years and age
Pfizer 3rd dose, 8 weeks after 2nd dose 3rd dose, at least 4 weeks after 2nd dose 3rd dose, at least 4 weeks after the second dose; 4th dose (updated booster) at least 2 months after 3rd dose 3rd dose, at least 4 weeks after the second dose; 4th dose (updated booster) at least 2 months after 3rd
Moderna 3rd dose, at least 4 weeks after 2nd dose 3rd dose, at least 4 weeks after 2nd dose 3rd dose, at least 4 weeks after the second dose; 4th dose (updated booster) at least 2 months after 3rd 3rd dose, at least 4 weeks after the second dose; 4th dose (updated booster) at least 2 months after 3rd
Johnson and Johnson Not recommended for this age group Not recommended for this age group Not recommended for this age group 2nd dose, at least 4 weeks after 1st dose; 3rd dose at least 2 months after 2nd dose * should be Pfizer or Moderna
Novavax Not recommended for this age group Not recommended for this age group Not recommended for this age group 3rd dose, at least 2 months after 2nd dose * should be Pfizer or Moderna

Bottom Line

As of October 2022, the definition of what it means to be fully vaccinated remains the same: two standard doses of Moderna, Pfizer, or Novavax (for 18 years and older) or the single-dose Johnson and Johnson vaccine. With the CDC changing the terms of what it means to be up-to-date on vaccines, experts suggest that "fully vaccinated" might evolve to include 3rd doses and updated booster shots. Regarding cost, covid vaccines and boosters are still free to all eligible individuals, regardless of immigration status.

As we enter flu season, it's essential to stay up to date with your covid-19 vaccines and boosters, flu shots, and preventive measures to boost your immune system.
