Compared with the original strain of the virus that causes COVID-19, the Delta variant is nearly twice as contagious. Because it spreads more quickly and easily, it’s important that a high percentage of the community is vaccinated to slow the spread of the virus.
‍
The vast majority of recent infections, hospitalizations, and deaths have been caused by the Delta variant among unvaccinated people. If you haven’t gotten the vaccine yet, make a plan today.
‍
If you have been fully vaccinated and live in an area of substantial or high community spread, you should wear a mask in public indoor spaces. Getting vaccinated and wearing a mask can help protect the more vulnerable in our communities, such as children not yet eligible for the vaccine or immunocompromised people.

A small percentage of people who are fully vaccinated have come down with COVID-19 — but most of these breakthrough infections are mild, with symptoms more like that of the common cold. Also, vaccinated people who do get COVID-19 seem to be infectious for less time than are unvaccinated people. While COVID-19 vaccines remain highly effective, no vaccine prevents illness 100% of the time.

The vast majority of hospitalizations and deaths continue to be among unvaccinated people.

Today’s vaccines are based on many years of research into vaccine technologies, further supported by unprecedented levels of collaboration and funding. Testing was thorough and comprehensive; no corners were cut.

Yes. There is no evidence that the vaccine can lead to loss of fertility, say experts at the American College of Obstetricians and Gynecologists and the American Society for Reproductive Medicine.

Yes, the Centers for Disease Control (CDC) and Prevention now recommends that pregnant women get the COVID-19 vaccine. The CDC analyzed new data from pregnant women who have been vaccinated and found no increased risk of miscarriage. Furthermore, pregnant women are more likely to get severely ill with COVID-19 and their babies are more likely to be born prematurely — so getting vaccinated can protect both you and your baby.

“The vaccines are safe and effective, and it has never been more urgent to increase vaccinations as we face the highly transmissible Delta variant and see severe outcomes from COVID-19 among unvaccinated pregnant people,” said CDC Director Dr. Rochelle Walensky.

If you are pregnant and have questions, talk with your health care provider.

Yes, the CDC now recommends COVID-19 vaccination for breastfeeding women. Based on how these vaccines work in the body, they are thought not to be a risk to you or your baby. Reports show that the mRNA vaccines might also help protect breastfeeding babies.

Yes. The COVID-19 vaccine has been well-studied among those ages 12 to 15. Additionally, the Centers for Disease Control and Prevention and the American Academy of Pediatrics have long recommended that adolescents and teens receive other vaccines, too, like influenza and meningitis.

Yes. Vaccines work by stimulating an immune response. Other medications work using an entirely different mechanism — so there is no interaction between the vaccine and any medications you might take. If you are taking medicines that weaken your immune system, you should talk to your health care provider.

No. None of the authorized COVID-19 vaccines contain the live virus that causes COVID-19. It’s normal to experience pain or redness on your arm where the shot was given, or sometimes tiredness, fever, or a headache for a day or two. This means your body is building protection against the virus.
