Vaccines help protect children and adults from infectious diseases that can be very serious. Keeping them up to date is essential to maintain protection, avoid contagion and the spread of certain viruses and bacteria.
1. What Are Vaccines?
They are preparations that activate the body’s natural defenses, generating immunity against viruses and bacteria. In this way, they protect us from certain diseases before coming into contact with them. You can read about the future of RNA and how it affects vaccine production.
Vaccines, duly approved, are safe and the main tool in the fight against serious diseases such as Covid-19. Some vaccines include:
- Covid-19 vaccine
- Influenza vaccine
- Pneumococcal Disease Vaccine
- Hepatitis A vaccine
- Hepatitis B vaccine
- Herpes Zoster Vaccine
2. How Do Vaccines Work?
They trigger the response of our immune system, which recognizes the virus, bacteria, or part of its components that are contained in the vaccine. They then generate an antibody response and leave an immunological memory in case, in the future, you come into contact with the pathogen that you want to prevent.
3. Why Do You Have to Get Vaccinated?
Vaccines play a very important role in maintaining the health of the population and avoiding certain diseases. They also protect children and adults who may present some risky condition. For this reason, every year the Ministry of Health reviews and updates the National Immunization Program, which is mandatory. Its main objective is to prevent morbidity, mortality, and disability due to certain communicable infectious diseases.
Although some of these diseases may be rare, in many cases thanks to the success of vaccines, today various viruses and bacteria can circulate in different parts of the world. They cause infectious diseases to infect those who are not protected through vaccination.
4. What Reactions Can a Vaccine Produce?
Most vaccine-associated reactions are mild and transient, generally consisting of a slight fever, temporary pain, or swelling at the puncture site. The latter can be treated with the application of a cold compress. If the pain is significant, an analgesic or anti-inflammatory such as Paracetamol or Ibuprofen can be administered.
The most serious adverse effects are extremely infrequent, approximately one case in a million doses, depending on the vaccine. This is far less than the effects produced by the disease itself from which it is sought to protect.
5. Are Vaccines Safe?
All approved vaccines undergo rigorous multi-stage or multi-phase studies before being used and, once marketed, continue to be regularly evaluated for possible adverse effects.
You have to know that, if we stop vaccinating, many old diseases that now pose no health risk may reappear.
Some vaccines are not mandatory and their prescription will depend on each case in particular according to parameters such as age, health status, and lifestyle of the people.h
Vaccination against Covid-19
The process of generation and approval of a vaccine can last more than 10 years. However, the collaboration between different countries and companies has allowed having the vaccine against Covid-19 in record time, in an accelerated way but not precipitated. Since all the usual phases in the development of a new vaccine have been completed. This will help to effectively control the disease as more people are inoculated.
It is estimated that to have a significant effect, approximately 70 or 80% of the country’s population should be inoculated. So, it is very important that in the meantime the known prevention measures continue to be strictly followed. Use of a mask, frequent hand hygiene, social distance, ventilation of spaces, avoid places with crowds of people, prefer outdoor activities, limit mobilization to essential activities and do not go out if you are sick or with symptoms.
