Seasonal and Pandemic A (H1N1) 2009 influenza vaccination coverage and attitudes among health-care workers in a Spanish University Hospital. 2010, Vírseda, Vaccine

More than half of health workers refused to be vaccinated against influenza, and only 16.5% were vaccinated against swine flu during the 2009 pandemic. They doubted the effectiveness of the vaccination and were afraid of side effects. (Madrid, Spain)

Hepatitis A

Hepatitis A outbreak in Barcelona among men who have sex with men (MSM), January-June 2017: A hospital perspective. 2017, Rodríguez-Tajes, Liver Int

46 cases were registered in the Barcelona hospital, 96% of them men, and 67% identified themselves as homosexuals. The authors write that the main risk factor is oral-anal contact during sex that the last outbreaks in Europe were between 2008 and 2011, and that because of these outbreaks, hepatitis A has been classified as an STD.


Emergence of invasive pneumococcal disease caused by nonvaccine serotypes in the era of 7-valent conjugate vaccine. 2008, Muñoz-Almagro, Clin Infect Dis

After the start of vaccination, the incidence of pneumococcal infection in Barcelona increased by 58%, and among children by 135%.
The incidence of vaccine serotypes decreased by 40%, and the non-vaccine serotypes increased by 531%.
Incidence of pneumonia and empyema among children under 5 years old rose by 320%.


Death from diphtheria in developed countries is so rare that every such case is widely reported in the media. In 2015, a boy died of diphtheria in Spain, and in 2008, a girl died in England. These seem to be the only deaths of children from diphtheria in developed countries in the last 30 years.

Whooping cough

Pertussis epidemic despite high levels of vaccination coverage with acellular pertussis vaccine. 2013, Sala-Farré, Enferm Infecc Microbiol Clin.

This is an epidemiological study in Spain analysing 421 cases of Pertussis, mostly in children under the age of one year. The vast majority of infected individuals (90%) had actually been fully vaccinated. The carriers were mostly fully vaccinated children aged 5-9 years. Only 8% of the 421 cases were hospitalized, and not one died. The authors conclude that despite a high level of vaccination in Spain, whooping cough is totally uncontrollable. Furthermore, they suggested that the real number of patients is probably much higher since only confirmed laboratory cases were considered in their analysis.
There are dozens of studies claiming the same thing: despite high global levels of pertussis vaccination, there have been more and more pertussis epidemics in the last 20 years. In addition, most of the infected have been vaccinated. More: [1], [2].


Identification of vaccine human papillomavirus genotypes in squamous intraepithelial lesions (CIN2 - 3) 2008, González-Bosquet, Gynecol Oncol
