What are vaccines for?
Vaccination strengthens the body's immune system and helps treat common diseases to which people may be exposed. In the vast majority of cases, vaccination prevents disease.
In some cases, a person can get a disease even if they have been vaccinated. However, the symptoms are milder and recovery is faster.
Some of the diseases against which vaccines protect us:
• Hepatitis A and B.
• Tetanus, diphtheria, pertussis
• Human papillomavirus (HPV) infection
• Measles, mumps and rubella
Benefits for all
Vaccinated people are less likely to transmit infectious disease to others. Thus, people who are vaccinated help protect people who cannot be vaccinated.
• people with weakened immune systems, such as cancer patients
These groups benefit from vaccinating others because in this way the disease cannot spread to the community.
A large number of vaccinations are required to achieve this collective immunity. When large numbers of people are vaccinated, the infection chains are broken. For example, according to the European Center for Disease Prevention and Control (ECDC), 95% of the population needs to be vaccinated against measles to prevent further spread of the disease in the community.
Reducing the burden on individuals
Vaccination, by helping to maintain the health of more people, helps reduce the social and psychological effects of disease on people and alleviates the burden on hospitals and healthcare systems. This means that resources can be made available to fight other diseases, such as cancer or Alzheimer's disease.
How do COVID-19 vaccines work?
The function of vaccines is based on the proper preparation of the individual's immune system (the body's natural defense) to recognize a specific disease and to be protected from it.
Most research on COVID-19 vaccines involves provoking a response against a protein (in whole or in part) that is found only in the virus that causes COVID-19. When a person is vaccinated, an immune response is generated. Most COVID-19 vaccines require two doses to build immunity.
If the person is later infected with the virus, the immune system is able to recognize it. Then she is already prepared to attack him.
Creating immunity:How effective is the COVID-19 vaccine?
After receiving both doses of the vaccine, most people will be protected. It takes at least a week after the 2nd dose to develop immunity, which, according to current scientific data, is estimated to last for 6 to 8 months. There is a small chance that someone will catch it even if they have received the vaccine. This means that it is important to continue to observe safety measures until a larger part of the population is vaccinated.
How safe are the vaccines that will be released?
So far, hundreds of thousands of people have received the COVID-19 vaccine without any serious side effects, other than the usual ones seen in some people after a vaccination. The vaccines that will be used in our country have been approved for their safety, quality and effectiveness by the competent international organizations, EMA (European Medicines Agency) and the FDA (Food and Drug Administration) and have been tested by the WHO ( World Health Organisation). All vaccines will have undergone clinical trials for immunogenicity and safety and will have been tested in several successive stages (phase 1 - 3 studies). According to the specifications, in order for a vaccine to be marketed, at least 30,000 people must take part in the phase 3 studies. This condition will also be met for these vaccines. It should be noted that monitoring for any rare adverse reactions continues internationally and after the start of their administration.
Do vaccines cause side effects?
Any side effects may be mild and transient, such as hand pain at the injection site, fever, malaise, myalgias and headache. All of these symptoms go away quickly, usually within twenty-four hours.
