Can diseases be caused by vaccination?

Can diseases be caused by vaccination?

Vaccines stimulate the immune system to produce an immune response similar to natural infection, but they do not cause the disease or put the immunized person at risk of its potential complications.

Can you spread disease if you are vaccinated?

Infections happen in only a small proportion of people who are fully vaccinated, even with the Delta variant. When these infections occur among vaccinated people, they tend to be mild. If you are fully vaccinated and become infected with the Delta variant, you can spread the virus to others.

What is a vaccine and how does it result in immunity?

Vaccines contain a harmless form of the bacteria or virus that causes the disease you are being immunised against. The bacteria or virus will be killed, greatly weakened, or broken down into small parts before use in the vaccine so that they can trigger an immune response without making you sick.

Can you get the Covid vaccine if you had Covid?

Getting a COVID-19 vaccine gives most people a high level of protection against COVID-19 even in people who have already been sick with COVID-19. Emerging evidence shows that getting a COVID-19 vaccine after you recover from COVID-19 infection provides added protection to your immune system.

Does the Covid vaccine stop you from getting Covid?

COVID-19 vaccines are safe and effective. Vaccines cannot give you COVID-19. You may have side effects after vaccination. These are normal and should go away within a few days.

Are you contagious after getting the Covid vaccine?

As a result, after you are fully vaccinated you can safely visit in person with friends and family. People are considered fully vaccinated two weeks after they get their second dose of an mRNA vaccine, such as Pfizer-BioNTech or Moderna, or two weeks after a single dose of the Janssen/Johnson & Johnson vaccine.
