Question: How does vaccination protect the body?

How do vaccines work?

What does the COVID-19 vaccine do in your body?

COVID-19 vaccines teach our immune systems how to recognize and fight the virus that causes COVID-19. Sometimes this process can cause symptoms, such as fever.

How does the COVID-19 vaccine boost your immune system?

Vaccines work by stimulating your immune system to produce antibodies, exactly like it would if you were exposed to the disease. After getting vaccinated, you develop immunity to that disease, without having to get the disease first.

What do we know about immunity from COVID-19?

Most people who are infected with COVID-19 develop an immune response within the first few weeks after infection. Research is still ongoing into how strong that protection is and how long it lasts.

Are there any long term effects of COVID-19 vaccine?

Serious side effects that could cause a long-term health problem are extremely unlikely following any vaccination, including COVID-19 vaccination. Vaccine monitoring has historically shown that side effects generally happen within six weeks of receiving a vaccine dose.

Will a COVID-19 vaccine alter my DNA?

No. COVID-19 mRNA vaccines do not change or interact with your DNA in any way.

How long does it take to build up immunity to COVID-19 after receiving the vaccine?

COVID-19 vaccines teach our immune systems how to recognize and fight the virus that causes COVID-19. It typically takes a few weeks after vaccination for the body to build protection (immunity) against the virus that causes COVID-19. That means it is possible a person could still get COVID-19 just after vaccination.

Can I still spread Covid if I get the COVID-19 vaccine?

Only a small portion of vaccinated individuals end up contracting the disease, though you still can. If contracted, there is still a chance of spreading it to others, which could be extremely dangerous if the household is immunocompromised or unvaccinated.
