Information update from Prince William Health District What You Should Know: 3rd Dose vs. Booster

Booster Dose
A booster dose of vaccine is administered when an initial sufficient immune response to a primary vaccine series is likely to have waned (decreased) over time.
A primary vaccine series is defined as either two doses of an mRNA vaccine (Pfizer-BioNTech/Comirnaty or Moderna) separated by the recommended number of 21 or 28 days or one dose of the Johnson & Johnson (J&J) vaccine.
Booster doses for COVID-19 are not currently recommended, however, the Center for Disease Control (CDC) and Advisory Committee on Immunization (ACIP) will review data on booster doses of COVID-19 vaccines in a systematic and transparent process.

Additional (Third mRNA) Dose
An additional dose is administered when certain people with weakened immune systems do not have a strong enough immune response to the initial 2-dose mRNA vaccine series.
A third dose of mRNA vaccine (Moderna or Pfizer) is now recommended at least 28 days after the second dose for people with weakened immune systems
When will Individuals need a booster vaccine dose?

This information is currently not available. For planning purposes, the federal government is looking at least eight months after completion of the primary series. However, regulatory and recommending agencies Food and Drug Administration (FDA and CDC) will need to first review the data before providing official recommendations regarding the timing of the booster vaccine dose. At This Time the PWHD WILL NOT offer or administer Booster Shots, only Third Doses to eligible individuals.

Why should individuals not try to get a COVID-19 Vaccine booster dose before it is formally recommended?

Getting the vaccine booster dose too soon (before you need it) might not provide additional protection. Getting a vaccine booster dose too late may put you at risk for severe COVID-19.

Care for any adverse effects in individuals who receive a COVID-19 booster dose outside of FDA, ACIP, and CDC recommendations are not covered by the Countermeasures Injury Compensation Program (CICP). These public health agencies take a number of factors into consideration (including timing of vaccine booster doses to maximize benefits) before providing formal recommendations.
