Does the COVID-19 vaccine prevent transmission?
Evidence suggests the U.S. COVID-19 vaccination program has substantially reduced the burden of disease in the United States by preventing serious illness in fully vaccinated people and interrupting chains of transmission.
Do you still have to wear a mask if you get the COVID-19 vaccine?
• If you have a condition or taking medications that weaken your immune system, you may not be fully protected even if you are fully vaccinated. You should continue to take all precautions recommended for unvaccinated people, including wearing a well-fitted mask, until advised otherwise by their healthcare provider.
Is COVID-19 vaccination still necessary, even after getting the disease and recovering?
Re-infection with COVID-19 occurs, although it is relatively rare. Also, at this point we do not know precisely how long people are naturally protected from getting COVID-19 again after clearing an infection. Follow-up periods for previously-infected individuals are not yet long enough to be able to draw conclusions on the duration of protection against infection beyond six months after infection. As a result, COVID-19 vaccination is recommended even for those who have recovered from the disease.
How does the COVID-19 vaccine help stop the spread of new strains?
As we vaccinate as many people as possible, as quickly as possible, we can stop the spread of the coronavirus. A reduction in transmission of the virus means fewer opportunities for it to mutate, which can help prevent the emergence of any other strains.
Does the COVID-19 vaccine reduce the risk of asymptomatic infection?
Overall, vaccination reduced the risk of asymptomatic and symptomatic SARS-CoV-2 infection by 79\% in vaccinated employees compared with their unvaccinated colleagues. Further, an analysis of asymptomatic infections alone found vaccination reduced the risk by 72\%.
Should you get the COVID-19 vaccine if you are reinfected with COVID-19?
But because it’s possible to get reinfected and COVID-19 can cause severe medical complications, the CDC recommends that people who have already had COVID-19 get a COVID-19 vaccine. In addition, COVID-19 vaccination might offer better protection than getting sick with COVID-19.
