The HPV vaccines did not cause two rare syndromes

The committee of the European Medicines Agency (EMA) has completed a detailed scientific examination analyzing scientific evidence on two syndromes, the complex regional pain syndrome (CRPS) and postural orthostatic tachycardia syndrome (POTS) in young women who received the vaccine against human papilloma virus (HPV).

The results of this review have concluded that it can not establish a link between vaccines Cervarix, Gardasil / Silgard and Gardasil-9 and the development of these two syndromes. Therefore, says the EMA in a statement, “there is no reason to change the way we are using these vaccines, or modify the information on these products.”

The CPRS is a chronic pain affecting the extremities, while POST is a condition that causes the heart rate increases abnormally, and produce dizziness, fainting, nausea and general fatigue. In some patients, these syndromes may seriously affect the quality of life. It is estimated to affect some 150 girls and young women between 10 and 19 per million women.

The EMA says that they has carefully reviewed the published research data from clinical trials and reports of side effects as well as consulting a group of experts in the field on this issue. Similarly, the agency notes that these syndromes may overlap with other complications such as chronic fatigue syndrome, which may make diagnosis both in the vaccinated population and the unvaccinated.

Over 80 million vaccinated women

Over 80 million women worldwide have so far received the HPV vaccines and in some European countries the vaccination rate has reached 90% in the age group recommended for vaccination. The use of this immunization aims to prevent many cases of cervical cancer.

With the new data on the table, the EMA concluded that the benefits of this vaccine still outweigh their risks. In any case, remember, immunization will remain under continuous monitoring, as this is done with other drugs.
