Covid-19 Vaccines work by training and preparing the body’s natural defenses – the immune system – to recognize and fight off the viruses and bacteria they target. After vaccination, if the body is later exposed to those disease-causing germs, the body is instantly able to destroy them, preventing illness.

  • Prevent you from getting Covid-19 or from becoming seriously ill or dying from Covid-19
  • Prevent you from spreading the Covid-19 virus to one to another
  • Add to the amount of individuals within the community who are shielded from getting Covid-19 making it harder for the disease to spread and contributing to herd immunity
  • Prevent the Covid-19 virus from spreading and replicating, which allows it to mutate and possibly become more resist to immune to vaccines

Are the COVID-19 vaccines safe?

Millions of people have safely received COVID-19 vaccines. All of the approved COVID-19 vaccines are carefully tested and still be monitored.

Like all vaccines, COVID-19 vaccines undergo a rigorous, multi-stage testing process, including large clinical trials that involve tens of thousands of individuals . These trials are specifically designed to spot any safety concerns

  • either a severe or immediate allergy after getting the primary dose of the vaccine
  • a previous allergic reaction to polyethylene glycol (PEG) or polysorbate
  • If you’re concerned about the ingredients in the COVID-19 vaccine, both Pfizer-BioNTechTrusted Source and ModernaTrusted Source provide full ingredient lists on their fact sheets for recipients and caregivers.

Should people with underlying health conditions get the vaccine?

Scientists currently don’t skills long innate immunity lasts after having COVID-19. Research on this topic is ongoing. A 2021 study of 188 people that had recovered from COVID-19 found markers of immunity up to eight months after infection.

Instances of repeat infection have so far only been documented in case Trusted Source studies Trusted Source. However, this does mean that it’s possible to contract the virus and become ill a second time. Vaccination can help prevent this from happening.

Currently, the Centers for Disease Control and Prevention (CDC)Trusted Source recommends that certain people who’ve had COVID-19 wait 90 days before getting the vaccine. This includes people who were treated with monoclonal antibodies or convalescent plasma.
