Detection of rotateq vaccine-derived, double-reassortant rotavirus in a 7-year-old child with gastroenteritis. 2014, Hemming, Pediatr Infect Dis J

Since the rotavirus genome consists of separate segments, when two different strains of the virus infect the same cell, they can exchange segments and create a new strain. This is the same reassortment, which happens on its own.
A case of gastroenteritis in a 7-year-old girl is reported here. A rotavirus strain was isolated from her stool sample. The strain was reassortant of two other human-bovine strains from the RotaTeq vaccine. However, the girl has not been vaccinated against rotavirus. Moreover, she has not been in contact with anyone who has been vaccinated. Her two brothers also had similar gastroenteritis symptoms, and they also have not been vaccinated or in contact with anyone who has been.
The isolated reassortant strain of the virus turned out to be stable and very contagious. The authors believe that this new virus is most likely circulating in the population. Reassortant viruses have previously been isolated, but only in those recently vaccinated with RotaTeq: [1], [2], [3].
Cases of detecting new virus strains from reassortment of wild virus with Rotarix vaccine strain are reported here.
It is reported here, that 17% of children secreted the virus after vaccination, and 37% of them secreted a double reassortant virus. Some children secreted the virus for a long time after the vaccination, form 9 to 84 weeks after the last dose.


Increase in bacteraemic pneumococcal infections in children. 1995, Baer, Lancet

Between 1992 and 1994, the incidence of pneumococcus in Finland increased twofold among children under two years of age, and 3 times among children under 16. The authors attribute this to the disappearance of Hib.

Haemophilus influenzae

Risk factors of invasive Haemophilus influenzae type b disease among children in Finland. 1989, Takala, J Pediatr

Visiting kindergarten is associated with a 5-fold increase in Hib risk, previous hospitalizations - with a 90% increase in risk, BF for more than 6 months lowered the risk by 53%.

Haemophilus influenzae

Why the rise in Haemophilus influenzae type b infections? 2003, Silfverdal, Lancet

In Sweden and Finland, there has been no increase in the number of cases of Hib after switching to acellular pertussis vaccine, the authors believe that this is due to the fact that longer breastfeeding is common in these countries.

Haemophilus influenzae

Clustering of cases of insulin dependent diabetes (IDDM) occurring three years after hemophilus influenza B (HiB) immunization support causal relationship between immunization and IDDM. 2002, Classen, Autoimmunity

Analysis of clinical trial data from Hib vaccine in Finland (116,000 children.) The Hib vaccine increases the risk of juvenile diabetes by 26%. Diabetes began 38 months after vaccination. The vaccine was also tested on diabetes-prone mice In vaccinated mice, diabetes developed more often.
In other studies, a similar increased risk of diabetes was detected, but since these studies were small, the results were not statistically significant.


An association of serum vitamin D concentrations <40 nmol/L with acute respiratory tract infection in young Finnish men. 2007, Laaksi, Am J Clin Nutr

Soldiers with low vitamin D levels (below 40 nmol/L) were 63% more likely to have respiratory illnesses than soldiers with a vitamin level higher than 40 nmol/L. Among those who smoked, the vitamin D level was lower than In non-smokers, soldiers who exercise more than 5 hours a week, the level of vitamin D was higher.


Epidemiology of three cases of severe diphtheria in Finnish patients with low antitoxin antibody levels. 2001, Lumio, Eur J Clin Microbiol Infect Dis

In the 90s, due to the opening of borders, a flood of tourists poured from Finland to Russia and from Russia to Finland. 400 thousand Finns visited Russia every year, and 200 thousand Russians visited Finland. 10 million trips were made. Despite the epidemic in Russia, only 10 Finns contracted diphtheria in Russia. Almost all of them were middle-aged men; only three of them had a severe form (described below), five had a mild form, and two were only carriers.

1) A 43-year-old resident of Finland visited St. Petersburg in 1993. There he kissed his local girlfriend, and when he returned to Finland, he was diagnosed with diphtheria. He was vaccinated against diphtheria 20 years ago, and was considered as unvaccinated (antibodies level was 0.01 IU/ml). His Russian girlfriend did not get sick. Another bacterium carrier was identified, who traveled in same group with the first one. He also had intimate relations with the same “girlfriend” in St. Petersburg. It was the first case of diphtheria in Finland in 30 years.
2) 57-year-old male visited Vyborg for one day in 1993 and came back infected with diphtheria. He denied having had close contact with the locals, but his friends said that he visited prostitutes. It is unknown whether he has been vaccinated (antibodies level was 0.06 IU/ml).
3) 45-year-old male visited Vyborg for 22 hours and came back infected with diphtheria. His friends said that he also visited a prostitute. He has been vaccinated and even received a booster shot one year before the trip (antibodies level was 0.08 IU/ml). He was the only one fully vaccinated, and also the only one who died.
All three of them consumed large amounts of alcohol during the trip, and two of them were chronic alcoholics.
