Do You Have to Quarantine If You’ve Been Vaccinated for COVID-19? – Healthline

In the early days of the COVID-19 outbreak, the medical communitys collective wisdom was that everyone should quarantine for 14 days if theyd been exposed to SARS-CoV-2, the coronavirus that causes COVID-19.

Now, however, 2 years of medical data and several vaccines later, we know a bit more about COVID-19, vaccinations, and quarantines.

In fact, the Centers for Disease Control and Prevention (CDC) has recently changed its recommended quarantine and isolation times for people who are vaccinated against COVID-19.

Keep reading to find out more about the latest quarantine recommendations.

Its important to understand some definitions of phrases and words commonly used to discuss COVID-19 and quarantine.

The first two phrases relate to vaccination status:

There are also two terms to keep in mind when it comes to quarantining or distancing yourself from others after COVID-19 exposure:

It may also be helpful to understand the terms that are used to discuss exposure:

According to the CDC, if youre vaccinated and exposed to COVID-19, you do not need to quarantine.

However, its recommended that you:

For clarity, the first day you were exposed is day 0. Day 1 is considered the first full day after you were in contact with a person who has tested positive for COVID-19.

If you arent up to date on your vaccines, or youre not vaccinated at all, the CDC recommends that you:

Below is a summary of the quarantine recommendations if youve been exposed to someone who has COVID-19:

All people who have a positive COVID-19 test should isolate for 5 days, regardless of their vaccination status, according to the CDC. This is true even if you dont have symptoms.

If your symptoms resolve and you are fever-free without the use of fever-reducing medications for 24 hours, you can end isolation.

However, you should wear a well-fitting mask for another 5 days when around people to minimize the chance of transmitting the coronavirus to others.

If you have a fever, remain in quarantine until the fever resolves.

If you never had symptoms, you can end isolation after 5 days, but wear a mask for 5 days after isolation.

If you had severe symptoms of COVID-19, its recommended that you isolate for at least 10 days. Consult a doctor before ending isolation.

Day 0 is your first day of symptoms, or the day you get a positive test. Day 1 is the first full day after you develop symptoms of COVID-19, or the day after your testing specimen is collected.

Everyone, regardless of vaccination status, should follow the 5-day isolation period with mask wearing until day 10. You should also avoid travel, and avoid contact with high-risk individuals.

Below is a summary of the quarantine recommendations if you test positive for COVID-19:

A vaccine is not a guarantee that you wont develop COVID-19 if you are exposed to the coronavirus. Instead, a vaccine aims to reduce the risk of:

However, even the most protective vaccines are not 100 percent effective, and its possible to develop a breakthrough infection.

But vaccinated people who develop COVID-19 are less likely to experience severe illness or require hospitalization. They are also less likely to die as a result of the infection.

According to the CDC, vaccine effectiveness against hospitalization in healthy people who have had two doses of an mRNA vaccine (like Pfizer or Moderna) is approximately 82 percent. Those whove had a vaccine booster restore the vaccines effectiveness against hospitalization to 97 percent.

For those who are immunocompromised, mRNA vaccine effectiveness against hospitalization is 69 percent with two doses. A booster increases it to 88 percent.

As coronavirus variants develop and spread globally, vaccination is an important tool in slowing the spread and reducing the risk of a variant being resistant to the current vaccines.

Vaccinated people who test positive for COVID-19 will likely experience milder symptoms. Its also likely that the duration of symptoms will be much shorter.

One 2022 study found that fully vaccinated people saw benefits during both the Delta variantpredominant period and the Omicron variant surge. Full vaccination protected against infection and death during Delta, and against infection during Omicron. This was especially true among people ages 50 to 64 and people over 65.

These milder symptoms may include:

If you test positive for COVID-19, the best course of treatment depends on your symptoms. Most people can treat their symptoms at home and will not have further issues. Typical self-care steps for COVID-19 include:

For some people, the antiviral remdesivir (Veklury) or an intravenous monoclonal antibody therapy may be recommended. These are typically reserved for people at high risk of complications from COVID-19.

Vaccinated people are less likely to develop severe disease. However, if you do test positive, keep an eye out for signs of a worsening infection. These symptoms include:

As medical professionals better understand COVID-19 and how vaccines affect how easily the virus is spread, advice on quarantine and isolation is changing. Today, the CDC has less strict quarantine requirements for people who have been vaccinated.

But the recommendations for isolation following a positive COVID-19 test remain the same, regardless of vaccine status.

Its important that everyone understand and follow the best practices for isolation and quarantine. This will help reduce the spread of the virus and potentially save hospitalizations and even deaths.
