COVID symptoms depend on how many shots you’ve had, study finds

If you’ve ever had COVID, you may know the symptoms of the virus all too well, including coughing, fatigue, and headaches.

But as the virus has evolved and new variants like Delta and Omicron have emerged, its most common symptoms have changed – and now, it seems, which ones you get depends on how many shots you’ve had. .

Getting the COVID shot lowers your risk of serious illness, hospitalization and death if you catch the disease, but according to new research, it could also dictate which batch of the virus’s mildest and most common symptoms you have. will eventually catch. It is believed that a large proportion of cases are still asymptomatic.

In an update to the ongoing Zoe Health Study, which has collected data from nearly 5 million participants since 2020, researchers said they identified symptoms that emerged in recent weeks, noting that they appeared to differ depending on vaccination status.

“Generally, we saw similar symptoms of COVID-19 reported globally in the app by people who had and had not been vaccinated,” the research team said in their update. “However, fewer symptoms were reported over a shorter period by those who had already received a shot, suggesting that they became less severely ill and improved more quickly.”

Symptoms by vaccination status

The most common current symptoms reported in fully vaccinated individuals, ranked by prevalence, were…

  1. Sore throat
  2. Runny nose
  3. Stuffy nose
  4. Persistent cough
  5. Headache

“Traditional” symptoms from the early months of the pandemic, such as loss of sense of smell, fever and shortness of breath, ranked low on the list among those who had received two doses of a vaccine, officials said. scholars, being named the sixth, eighth, and 29e most common COVID symptoms.

“Curiously, we noticed that people who had been vaccinated and then tested positive for COVID-19 were more likely to report sneezing as a symptom than those who had not received an injection,” they added.

Among those who had received only one dose of vaccine, the most common recent symptoms were slightly different:

  1. Headache
  2. Runny nose
  3. Sore throat
  4. To sneeze
  5. Persistent cough

In unvaccinated people, according to the study, the symptoms were “more recognizable compared to the traditional original classification”, although they acknowledged that there had been some changes since the onset of COVID.

If you haven’t received a dose of the COVID vaccine, the symptoms you’re most likely to get from the virus — according to the Zoe study — are…

  1. Headache
  2. Sore throat
  3. Runny nose
  4. Fever
  5. Persistent cough

“Loss of smell comes in at No. 9 and shortness of breath comes far down the list at No. 30, indicating that previously recorded symptoms change as virus variants evolve,” the research team said.

Being fully vaccinated and boosted against COVID reduces the risk of becoming seriously ill with the virus, especially if you are also young and healthy.

However, the Omicron variant and its progeny, such as BA.5, which is currently the dominant strain of the virus in America, are thought to cause milder disease than their predecessors, even in the unvaccinated.

Globally, COVID infections are on the rise, with experts predicting there will be an increase in deaths as the northern hemisphere enters its winter months.

In August, Dr. Anthony Fauci, the White House’s top medical adviser, urged Americans to get vaccinated or risk “being in trouble” during colder seasons.
