Why vaccination remains the main protection against infections in 2026
Vaccination is the most effective public health tool that has allowed humanity to control the spread of dangerous infections for decades. By creating artificial immunity, the body is able to prepare for encounters with viruses and bacteria without suffering a severe form of the disease.
Today, immunization is not just a personal responsibility, but the foundation of collective security. It prevents large-scale epidemics, reduces the burden on health systems, and saves millions of families from the tragic consequences of infectious diseases.
WHO statistics: the impact of immunization on global mortality
According to the World Health Organization (WHO), the implementation of mass vaccination programs has significantly reduced mortality from diseases that were previously considered fatal or led to lifelong disability (for example, smallpox or polio).
The dynamics of global life-saving through immunization shows steady growth, which is associated with the emergence of new vaccines and improved logistics for their delivery to the most remote corners of the planet.
Table 1. Estimated number of lives saved through immunization
| Period | Event / Change in vaccination strategy | Lives saved (annually) |
|---|---|---|
| By 2020 | Active introduction of new vaccines (against rotavirus, pneumococcus) and expansion of national vaccination calendars. | ~2.5 million |
| 2021 – 2023 | Stabilization of healthcare systems after the pandemic, restoration of planned routine immunization. | ~2.7 million |
| 2024 – 2026 | Global expansion of access to vaccinations in low-income countries, introduction of new technologies (mRNA platforms, etc.). | ~3.0 million |
How does vaccine immunity work and why can it fade?
When a person receives a vaccine, their blood begins to produce antibodies. specific antibodies (immunoglobulins class G or IgG). They act as “soldiers” who instantly recognize the real enemy in the event of a real infection and neutralize it before the disease causes damage to organs and tissues.
However, over time, the level of protective antibodies to some infections may decrease. This depends on the individual characteristics of the body, age, health status and directly on the type of vaccine. That is why there is a need to check the state of your immune system protection.
Checking the effectiveness of protection in Medi Lab Plus
Patients often ask how to find out if the vaccination is still effective, or if immunity has been formed after a previous illness (which may have been asymptomatic). The best way is to have a laboratory test to measure the level of specific IgG antibodies.
In the laboratory Medi Lab Plus You can undergo a highly accurate analysis of the most important indicators, which will allow you and your doctor to make an informed decision about the advisability of revaccination.
Table 2. Key laboratory parameters for assessing immune status
| Test name (IgG) | Description of infection and risks | To whom and when is this critically important? |
|---|---|---|
| Antibodies to measles virus | Measles is a highly contagious viral infection that causes severe complications (pneumonia, encephalitis). | Adults who are unsure whether they were vaccinated as a child, as well as during epidemic outbreaks. |
| Rubella virus antibodies | The virus causes a mild rash in adults, but is deadly to the fetus if infected by a pregnant woman. | Critical for women when planning pregnancy for the prevention of congenital rubella syndrome. |
| Antibodies to diphtheria toxoid | Diphtheria is a severe bacterial infection that causes suffocation and toxic damage to the heart. | To check for protection. Reminder: Adults should update their diphtheria vaccination every 10 years. |
| Antibodies to mumps virus | Mumps affects the glandular organs and can lead to infertility. | To assess comprehensive immunity after the combined MMR vaccine (measles, mumps, rubella). |
Frequently Asked Questions (FAQ)
- What does a positive IgG antibody test result mean?
A positive result indicates that your body has successfully encountered the infection or vaccine and has formed a stable immune memory. You have effective protection against a specific disease.
- Can I get tested for antibodies after vaccination?
Yes, of course. This is the best and only scientifically proven way to check whether the vaccine “worked” (seroconversion occurred) and whether the body has developed sufficient protective titers. The test is usually taken 3–4 weeks after completing the vaccination course.
- How often should antibody levels be checked?
It depends on the type of infection and life circumstances. Doctors strongly recommend doing this before planning a pregnancy, when the epidemiological situation in the country changes, before working in medical or children's institutions, or if you have completely lost your medical card with the dates of childhood vaccinations.
- Is special preparation required for the analysis?
Before any laboratory test, it is important to properly prepare the body. In particular, it is recommended to take a blood test for antibodies to infections on an empty stomach (preferably in the morning, after abstaining from food for 8–12 hours). Read more about the rules of preparation and the role of immunization here: https://medilab.km.ua/imunizatsiya/. You can drink clean, still water. Otherwise, follow the usual recommendations for donating capillary or venous blood.
