那么，接种过百白破疫苗或得过百日咳还会再次感染吗？答案是：有可能再次感染。因为无论是接种疫苗还是自然感染，人体均不能获得终身免疫。随着时间的推移，人体中对百日咳鲍特菌的抗体会逐年衰减。虽然全球范围内百日咳疫苗均保持着较高的接种率，但每隔3-5年就会发生一次较大流行，导致这一现象的原因有很多，疫苗保护效力的下降是其中一个重要因素。

Sufficient and convenient charging infrastructure is a crucial factor in promoting electric vehicle consumption. Therefore, EU member states such as France and Germany provide substantial direct grants and tax incentives for the installation of charging facilities. In 2016, France provided at least EUR 320 million in grants through the “Advenir” program to subsidize these installations.[67] France also implemented VAT incentives and tax credit policies. The VAT for home charging facilities is set at 5.5%， while the VAT for installing charging devices in buildings over two years old is 10%， and for buildings under two years old, it is 20%. Additionally, from 2021 to 2023, buyers of charging devices can benefit from a special tax credit of up to EUR 300 for purchasing and installing these facilities.[68] While in German, in July 2022, the German federal government established the Climate and Transformation Fund (KTF)， using the national budget to support energy transition and climate protection from 2023 to 2026.[69] In October 2022, Germany’s Federal Ministry for Digital and Transport approved a charging infrastructure subsidy plan, fully supported by the fund, with a budget of EUR 630 million covering 68 specific measures. In June 2023, the ministry allocated EUR 900 million to improve the subsidy plan, with EUR 500 million dedicated to private charging stations and EUR 400 million to commercial ones.[70]
