SARS-CoV-2 Vaccine

Motivos para vacunarse contra la COVID-19.

Vaccines build long-lasting, active immunity against disease by helping the body’s ability to fight a virus. There may be cases in which the vaccine does not prevent you from contracting the COVID-19 virus. However, if you do catch it, the vaccine could keep you from getting seriously ill or prevent complications.

Reasons to get vaccinated against COVID-19

  • It helps you build immunity against SARS-CoV-2, the virus that causes COVID-19.
  • The vaccine could keep you from getting seriously ill, prevent complications, or die from the disease.
  • While each vaccine works differently, all COVID-19 vaccines elicit an immune response so your body remembers how to fight the virus in the future.
  • Prevent the virus that causes COVID-19 from spreading and replicating, contributing to herd immunity.

COVID-19 Vaccine Dose

Learn why the COVID-19 vaccine is applied in one or two doses and what is the official recommendation for its application, combining, or not combining the different vaccines.

How do COVID-19 vaccines work?

Any vaccine is intended to generate immunity against a disease by producing antibodies that activate the body’s natural defenses, strengthening the immune system.

The main types of COVID-19 vaccines that are currently available or in large-scale clinical trials include the following:

Messenger RNA (mRNA) vaccine.

mRNA vaccines are a new type of vaccine that teaches our cells to make an S protein, which triggers an immune response that produces antibodies, protecting us from infection if the real virus enters our bodies.

This vaccine cannot cause an infectious disease such as COVID-19 since it does not contain the live virus that causes COVID-19.

Vector-based vaccine.

Viral vector vaccines contain a modified version of another virus (viral vector) to instruct our cells and make copies of protein S. Once it has protein S, the immune system responds by creating antibodies and defense white blood cells. If you get infected with the COVID-19 virus, the antibodies fight the virus.

Viral vector vaccines cannot get you infected with the COVID-19 virus or the viral vector virus. In turn, the genetic material they provide does not become part of your DNA.

Protein subunit vaccines.

This type of COVID-19 vaccine contains harmless S proteins. Once the immune system recognizes the S proteins, it creates antibodies and defense white blood cells.

COVID-19 variants, do vaccines work for the new variants?

When a virus has one or more mutations they are called ``variants`` of the original virus. Some of the worrying variants of COVID-19 are Alpha. (B.1.1.7), Beta (B.1.351), Gamma (P.1), Delta (B.1.617.2).

Vaccines against COVID-19 continue to be effective with severe and mild forms, although they decrease by a certain percentage. Remember that receiving a dose does not grant immediate immunity, be cautious and comply with the complete vaccination schedule.
