Sure, vaccines are good for you, and only crazed right wing fringe dwellers would think otherwise. Why, just ask the Chinese:
“The Chinese government has admitted that hundreds of thousands more doses of children’s vaccines are faulty, bringing the total number of vaccines known to be defective there to nearly one million. The State Council of China announced that another batch of vaccines for diphtheria, pertussis and tetanus (DPT) that were produced by the firm Changchun Changsheng Biotechnology, were considered “substandard.” Most of the doses were sold to authorities in the Shandong province in northeastern China, and some have already been given to children. The latest batch of 247,200 vaccines joins the 253,338 defective DPT vaccines from the same company that were discovered last November, along with more than 400,000 produced by a different company. According to the South China Morning Post, 76 percent of those children who were given injections from the first substandard batch have already been treated by doctors, and there are now plans in place to treat those who received injections from the second batch. Although the Chinese government has done its best to prevent people from talking about the crisis, Chinese social media is still full of conversation about the topic. There have also been reports that the company used expired ingredients and altered testing records.’
See, nothing to be unduly concerned about, even with a preposition at the end of a sentence.
