The Importance of Complying with Vaccination Protocols in Developed Countries: "Anti-Vax" Hysteria and the Spread of Severe Preventable Diseases.

BACKGROUND: Vaccines are very effective medical tools for disease prevention and life span increase. Controversies have raised concern about their safety, from autism to polio vaccine contamination with simian virus 40 (SV-40). Hysteria surrounding vaccine-associated risks has resulted in a declining number of vaccinations in developed countries. Outbreaks of vaccine-preventable diseases (e.g. measles) have occurred in Europe and North America, causing also some causalities. OBJECTIVES: In this review, data on safety and efficacy of vaccines are discussed, showing that the benefits of vaccines far outweigh the risks and that it is important to comply with vaccination protocols, to avoid spreading of severe, preventable diseases. METHODS: Those opposed to vaccinations suggest that scientific literature supporting vaccines is influenced by pharmaceutical companies. In this review, studies on influenza produced by independent scientists and those authored by those who received some kind of benefit from the industry are discussed separately. All the chosen papers were selected through a MEDLINE research. RESULTS: Vaccination rates are decreasing, even though they are effective public health tools. Influenza, for example, is responsible for 250,000-500,000 deaths each year, according to the WHO. Yet, campaigns to extend influenza vaccine to all elderly subjects report little success, because of the vaccine scare and because not all patients develop immunity following vaccination. CONCLUSIONS: This review proves that vaccine hysteria is detrimental because: 1) it causes an increased morbidity and mortality from preventable diseases; 2) it jeopardizes research for new vaccines; 3) patients are reluctant to accept any form of immune-therapy, commonly referred to as "vaccination".

[Screening of obesity, overweight and thinness in a children population in Rome, Italy]. / Screening per obesità, sovrappeso e sottopeso in una popolazione in età scolare a Roma, Italia.

AIM: Objective of the study was to estimate the prevalence of obesity, overweight and thinness in a children population in Rome, Italy. METHODS: The study sample was created, after informed consent, in a school in Rome, available to the study project. A total of 595 children (289 males, 306 females), aged between 6 to 19 years, underwent following measurements: height and weight, evaluation of body mass index. RESULTS: A normal BMI was recorded in 73.6% of cases. Morbid obesity, obesity, overweight, and thinness grade 1 and 2 prevalence was 1.2%, 4%, 15.3%, 9.2% and 3.8%, respectively, without statistical differences in both genders, except the prevalence of overweight that resulted statistically significant (11.4% females vs. 19.3% males, P<0.05). Differences in the age groups have been found. About 17.2% and 18.7% of children between 7 to 11 years were overweight and obese and about 33.3% and 26.6% between 6 to 8 years thin grade 1 and 2, respectively. CONCLUSION: The study suggests a prevalence of overweight and obesity in our sample lower than that reported in a recent epidemiological survey carried out on Italy. Attention must be taken to underweight, particularly with regard to the most severe form, as a public health problem for all possible risks correlated. In addition, our study shows the involvement of specific age groups. This finding, if confirmed in a larger population, should be associated with a major attention on specific age groups at risk, in order to plan an appropriate treatment program.
