What are COVID-19 Vaccines?
COVID-19 vaccines are explicitly made to help your body develop immunity against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Once your vaccination is complete, your body can begin to successfully detect foreign cells in your body and prevent severe infection.
Most COVID-19 vaccinations will require two doses, with the exemptions of Johnson & Johnson and AstraZeneca that only need one. The vaccines are guaranteed to be safe for use and efficient in triggering the necessary immune responses to prevent symptomatic infections.
Despite the side effects some brands may cause, getting vaccinated can significantly reduce the risks of infection when exposed to the virus. However, this does not imply that you will be immune to the virus itself.
Types of COVID-19 Vaccines
Different types of COVID-19 vaccines offer various methods of providing immunity. It will take a few weeks after completing your vaccination for your body to produce the necessary T-lymphocytes and B-lymphocytes cells against the virus.
Three types of COVID-19 vaccines have been authorized and recommended by health organizations: mRNA, protein subunit, and vector vaccines.
mRNA vaccines contain virus materials that are known to cause COVID-19. These materials will alert our cells and give them instructions to create a protein that mimics infections. Once these proteins are made, the genetic material from the vaccine is broken down, triggering immune responses.
