Tarrant County Public Health’s protocol follows updated CDC guidance on Vaccinated Persons.

While mRNA COVID-19 vaccines have demonstrated high efficacy at preventing severe and symptomatic COVID-19, there is currently limited information on how much the vaccines might reduce transmission and how long protection lasts.

In addition, the efficacy of the vaccines against emerging SARS-CoV-2 variants is not known.

At this time, vaccinated persons should continue to follow current guidance to protect themselves and others, including:

• wearing a mask
• staying at least six feet away from others
• avoiding crowds, avoiding poorly ventilated spaces
• covering coughs and sneezes
• washing hands often
• following CDC travel guidance, and
• following any applicable workplace or school guidance, including guidance related to personal protective equipment use or SARS-CoV-2 testing.
  

However, vaccinated people with exposure to someone with suspected or confirmed COVID-19 are not required to quarantine if they meet all the following criteria:

• Are fully vaccinated (i.e., being fully vaccinated is two weeks following receipt of the second dose in a two-dose series or two weeks following receipt of one dose of a single-dose vaccine)

• Are within three months following receipt of the last dose in the series

• Have remained asymptomatic since the current COVID-19 exposure.
  

People who do not meet all three of the above criteria should continue to follow current quarantine guidance after exposure to someone with suspected or confirmed COVID-19.
