The vaccinations they cause very few side effects and there is no evidence that this type of therapy causes autism or type 1 diabetes, according to the conclusions of a federal committee of experts from the United States, who have analyzed the results of more than 1,000 research studies , published by the Institute of Medicine (IOM, for its acronym in English).

According to the head of the committee, Ellen Wright Clayton, professor of Pediatrics and director of the Center for Biomedical Ethics and Society of the Vanderbilt University in Nashville (United States), only found some cases in which vaccines can trigger adverse effects and, of these, most were resolved in the short term and could be self-controlled.

Since 1994 a comprehensive report on the side effects of vaccines was not prepared, and was requested by the US Department of Health and Human Services to help guide the Vaccine Injury Compensation Program, which provides financial assistance to assist to children who suffer side effects after being vaccinated.

The experts analyzed eight types of vaccines that are used frequently: triple MMR; the DTaP; that of chickenpox; the flu; Hepatitis B; the meningococcal vaccine; those that include tetanus; and the one that fights the human papillomavirus (HPV). These vaccines exert a prophylactic action against various conditions, such as mumps, measles, hepatitis, chicken pox, diphtheria, whooping cough, tetanus, meningitis, meningococcal disease and cervical cancer.

Mild side effects

The suspicion that vaccines can cause autism or other pathologies has led many parents to decide not to immunize their children, despite the information repeatedly reported by the health authorities with the intention of transmitting peace of mind.

In this regard, Clayton stated that the study has shown that the MMR vaccine does not generate autism, nor type 1 diabetes, and other types of immunizations, such as the inactivated influenza vaccine, do not cause Bell's palsy (a temporary facial paralysis) or aggravate asthma.

Scientists did note that the MMR vaccine can cause seizures when patients have fever very high after its administration, although this effect is temporary. In people with severe deficiencies of the immune system, this vaccine can also cause a rare form of brain inflammation.

Those with a poor immune system are also more likely to suffer reactions such as brain inflammation, meningitis, hepatitis, pneumonia, or shingles, with the varicella vaccine.

Six vaccines - MMR, varicella, influenza, hepatitis B, meningococcal, and those that contain tetanus - can also trigger an allergic reaction, which appears shortly after the injection, but to solve this problem, it is only necessary for patients to remain in the hospital. Vaccination center 15 minutes more to check that they do not show any unfavorable reaction.
