Are the vaccines safe?

According to the World Health Organization (WHO), all approved vaccines are usually under rigorous testing during the phases of clinical trials before being administered to infants, children and adults. They even continue to be evaluated regularly once they are marketed. Through frequent studies, new information and important data is discovered, which allows the constant updating of recommendations on a vaccine or perhaps the implementation of a new one. Everything varies according to the epimediology of the country.

There are serious and highly contagious diseases that for years seriously affected babies, children and adults, causing the death of millions of people


Because of this, each nation has a vaccination calendar that serves as a guide in the application of vaccines and also to know their latest changes and thus be up to date with important aspects of your baby’s vaccination. This is very important, since it can vary according to the health situation of the country or region.

While vaccines are safe, do vaccines have side effects?

What are the risks of vaccination?

The side effects after the application of a vaccine should not be cause for concern or rejection, since its benefits are greater than the possible risks or side effects, in addition to the consequence of the disease or death that could cause not to apply the vaccines.

Most reactions to vaccines are mild and temporary

According to WHO, most reactions to vaccines are mild and temporary. Among the usual reactions, they are found

  • Redness of the area
  • Pain and swelling at the injection site
  • Discomfort
  • Fever or low-grade fever
  • Threw up

Although there are very rare cases in which there are serious side effects from vaccines, your baby is not exempt from suffering them, so experts recommend staying at least half an hour at the health center after vaccination. There are also exceptions for children who can not receive certain vaccines, due to this you should consult with your trusted pediatrician to be aware of your baby’s particularities.

Some cases where children can not get vaccinations.

  • Children with allergies to a component of a vaccine.
  • Children with weakened immune systems due to illness or medical treatment, such as chemotherapy.

What diseases prevent vaccines?

There are serious and highly contagious diseases that for years seriously affected babies, children and adults, causing the death of millions of people. Many of these diseases have been controlled and even eradicated (as is the case of the Smallpox), through the use of vaccines. One of the main reasons why vaccines are important is that they offer an important immunization against the spread and spread of possible diseases.

Let’s see what are the preventable diseases through vaccination and from which your baby will be safe.

1. Measles: The Unicef emphasizes that all children should be vaccinated against measles because it is a major cause of malnutrition, mental retardation, hearing and sight.

2. Poliomyelitis: Of every 200 affected children, one will be disabled for the rest of his life, according to the UNICEF, also emphasizes that everywhere children vaccinate against polio, whose symptoms are weakness in the limbs or inability to move.

3. Tetanus, whooping cough and diphtheria: For tetanus, UNICEF recommends tetanus vaccine, because tetanus bacteria or spores that develop in wounds or dirty cuts can be deadly without the tetanus vaccine. It is also important that the six-week-old infant receives its first vaccine against diphtheria, whooping cough and tetanus, according to Unicef.

4. Yellow Fever: Yellow fever is transmitted by infected mosquitoes, its symptoms according to WHO are: fever, headaches, muscle aches, nausea, vomiting and fatigue. WHO warns that infants younger than 9 months should not be vaccinated against this disease, except cases of epidemics occurs, so children should be vaccinated 6-9 months in areas at high risk of infection.

5. Hepatitis B
The Unicef notes that “In countries where hepatitis B is a problem, 10 out of 100 children will harbor the infection for the rest of their lives if they are not vaccinated”. They also point out that children infected with hepatitis B also put their future at risk, since there is a likelihood of developing liver cancer as an adult.

6. Haemophilus influenzae type B (Hib): For Unicef, this is one of the most dangerous bacteria for children, mainly in children under five years of age. In many countries, pneumonia caused by this bacterium is deadly for many young children. Hib can also be the cause of meningitis.
