It takes a couple of weeks for your body to build immunity after vaccination.
Hence, When does immunity start after the Pfizer COVID-19 vaccine? Data released by the U.S. Food and Drug Administration (FDA) show that COVID-19 protection from the Pfizer/BioNTech vaccine was demonstrated in the clinical trials at about 14 days after the first shot. The FDA said some level of immunity may start sooner, but how much is not certain.
Indeed, 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 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.
Then, Can you still get COVID-19 after vaccine?
Most people who get COVID-19 are unvaccinated. However, since vaccines are not 100% effective at preventing infection, some people who are fully vaccinated will still get COVID-19. An infection of a fully vaccinated person is referred to as a “breakthrough infection.”

Why does the COVID-19 vaccine cause arm pain?
Your body recognizes the protein as an antigen — something foreign — and starts reacting to it with inflammation at the injection site. This is why the first shot very commonly causes arm pain.
