These are the side effects that each of the COVID-19 vaccines can cause

What side effects cause vaccine applications? When one goes to get vaccinated against him COVID-19In many cases, health personnel recommend taking a paracetamol pill to reduce the effects of the dose because, although in most cases they are mild, it is better to avoid discomfort.

Vaccines save lives and their efficacy has been demonstrated in the last pandemic wave dominated by the omicron variant. The mortality rate has been reduced, as well as the severity of symptoms, hospitalizations and admissions to intensive care units.

However, when receiving any of the doses of the vaccines to protect us from a severe or lethal coronavirus, they can cause side effects that can last one or two days. Next, we detail what they are:

IN WHAT CASE SHOULD I SEEK MEDICAL ATTENTION FOR SIDE EFFECTS OF THE VACCINE?

While side effects from the vaccine may affect your ability to do your daily activities, they should go away within a few days, says the National Center for Immunization and Respiratory Diseases (NCIRD) of the United States. In most cases, the discomfort of pain or fever is a normal sign that the body is creating protection. Contact a doctor or health care provider:

  • If irritation or tenderness at the injection site worsens after 24 hours.
  • If the side effects bother you or do not seem to go away after a few days.

HOW LONG DOES IMMUNITY LAST AGAINST COVID-19?

The immunity generated by the person after contracting COVID-19 It is an average of three months. After that period, the possibility of reinfection increases, according to what Luis Pampa, an infectious disease specialist at the National Institute of Health (INS) of Peru, told the Andean news agency.

He explained that this is due to the duration of the antibodies that, after 90 days, begin to decline in both humoral and cellular immunity, which are responsible for defending the body against pathogens.

WHAT ARE VACCINES?

According to the World Health OrganizationVaccines reduce the risks of contracting diseases by strengthening the body’s natural defenses to develop protection. When you get a vaccine, your immune system responds.

There are now vaccines to prevent more than 20 life-threatening diseases, helping people of all ages live longer and healthier lives. Vaccines are estimated to prevent between 2 and 3 million deaths each year from diseases such as diphtheria, tetanus, whooping cough, influenza and measles. Immunization is an essential component of primary health care and an unquestioned human right, he adds.
