Hepatitis A

Hospitalization and mortality due to hepatitis A in Taiwan: a 15-year nationwide cohort study. 2016, Chen, J Viral Hepat

In Taiwan, hepatitis A has been vaccinated by the native population since 1995. One study found that the incidence in Taiwan decreased more than 3-fold due to vaccination, despite the fact that only 2% of the population had been vaccinated, and the majority of those vaccinated lived in the mountains and isolated islands.
In another study, it was found that only 0.4% of the unvaccinated population had antibodies to hepatitis A, from which the authors conclude that hygiene is more responsible for reducing morbidity than vaccination. improved hygiene emost shifted from children at an older age.

In Taiwan, in 2001-2009, the incidence of chickenpox declined from 7.14 to 0.76 per 1000, and the incidence of shingles increased from 4.04 to 6.24 per 1000. The chickenpox is more sick in the winter months, and shingles on the contrary, more in summer months.

SIDS

Vaccination and unexplained sudden death risk in Taiwanese infants. 2017, Huang, Pharmacoepidemiol Drug Saf

В марте 1992 года 8 младенцев в Тайване умерли в течение 36 часов после прививки DTP. Семеро из них получили вакцины из одной партии (которая составляла 58% из используемых на то время вакцин), что побудило власти приостановить вакцинацию этой партией.
Авторы проанализировали случаи СВДС в Тайване в 1996-2013 годах, и заключили, что риск внезапной смерти после DTP повышен на 60% у девочек в течение двух дней после прививки. Авторы заключают, что вакцина, вероятно, лишь ускорила смерть этих девочек на пару дней, и им и так было суждено умереть от СВДС, просто немного позже.
