COVID-19 can cause serious illness and hospitalization

Get the facts about the updated COVID-19 vaccines from Pfizer and BioNTech.

COVID-19 is an illness caused by the SARS-CoV-2 virus.

The virus that causes COVID-19 continues to evolve and change. These changes occur over time and can lead to new variants. COVID-19 is very contagious and can spread quickly. It most often causes respiratory symptoms, but other parts of your body may also be affected by the disease. Most people with COVID-19 have mild symptoms, but some people become severely ill.

COVID-19 impacts the body differently from person to person.

COVID-19 can cause symptoms ranging from mild to very severe. These COVID-19 symptoms may appear 2 to 14 days after exposure and can include:
  • Fever or chills
  • Cough
  • Shortness of breath or difficulty breathing
  • Fatigue
  • Muscle or body aches
  • Headache
  • New loss of taste or smell
  • Sore throat
  • Congestion or runny nose
  • Nausea or vomiting
  • Diarrhea
This is not a comprehensive list of symptoms.

Several risk factors for COVID-19

Older adults and people who have underlying medical conditions like heart or lung disease or diabetes are at a higher risk of getting very sick from COVID-19.

Learn more about risk factors that make it more likely to get very sick with COVID-19 at the CDC website.

Why were COVID-19 vaccines updated?

Why were COVID-19 vaccines updated?

People who were previously vaccinated with COVID-19 vaccines may no longer be adequately protected.

The virus that causes COVID-19 evolves and changes often, which means it can escape the defenses the immune system built up against earlier variants.

That’s why the updated COVID-19 vaccines from Pfizer and BioNTech are designed to help protect against recent variants.

Help protect your loved ones against COVID-19 with the updated COVID-19 vaccines from Pfizer and BioNTech—available in doctors’ offices, hospitals, clinics, and pharmacies across the US.
