Vaccines

Vaccines — including COVID-19 vaccines — work to protect the people who get the vaccine, as well as the people around them.

Vaccines help our bodies fight infections faster and more effectively. A vaccine is a substance that teaches your body to recognize and get rid of viruses or bacteria by triggering a response from your immune system. Vaccines help your body stand ready to protect you from getting sick if you run into the virus or bacteria in the future, even if you’ve already had COVID-19.

Did You Know...

Current data show that the antibodies you make after a COVID-19 vaccine may recognize and protect against virus variants like Delta and Gamma.

Face coverings, physical distancing, quarantining of those exposed to COVID-19, and isolating those infected can help stop the spread. But we need a safe and effective vaccine to conquer COVID-19. Learn how enrolling in a clinical trial can help: https://go.usa.gov/xfShb

When you get a vaccine, your body’s immune system is primed to recognize and attack a specific pathogen if it tries to invade the body. And since vaccines are made of very small amounts of weakened or inactivated germs or only a component of the germ, they won’t give you the disease. NIH-funded scientists are working hard to find a COVID-19 vaccine that is safe and effective. Learn more: https://go.usa.gov/xfShb

Vaccines don’t just protect you — they also protect the people around you. When enough people get vaccinated against a certain disease, germs can’t travel as efficiently — and the entire community, including vulnerable populations and those who cannot get vaccinated, is less likely to get sick. That’s why NIH-funded scientists are working so hard to find a COVID-19 vaccine. Learn more: https://go.usa.gov/xfShb​​​​​​​

Cubrirse el rostro, distanciarse físicamente, poner en cuarentena a las personas expuestas al COVID-19 y aislar a las personas infectadas puede ayudar a detener la propagación. Pero necesitamos una vacuna segura y eficaz para vencer al COVID-19. Descubra cómo su participación en un estudio clínico puede ayudar: https://covid19community.nih.gov/espanol

Cuando recibe una vacuna, el sistema inmunológico de su cuerpo está preparado para reconocer y atacar a un germen infeccioso específico si intenta invadir el cuerpo. Dado que las vacunas están hechas de cantidades muy pequeñas de gérmenes debilitados o inactivados, o solo de un componente del germen, no le transmitirán la enfermedad. Los científicos financiados por los NIH están trabajando arduamente para encontrar una vacuna contra el COVID-19 que sea segura y efectiva. Más información: https://covid19community.nih.gov/espanol
