According to a slideshow uploaded online, scientists at Anvisa, Brazil's regulator, said they tested samples of the booster shot and found it was "replication competent" -- meaning that once inside the body, the adenovirus can continue to multiply.
They added that this had likely occurred because of a manufacturing problem called "recombination," in which the modified adenovirus had gained back the genes it needed to replicate while it was being grown inside engineered human cells in a lab.

Rasmussen, a research scientist at Canada's Vaccine and Infectious Disease Organization, described the error as a quality control issue, rather than a problem inherent to the technology.
If batches used in the real world were tainted, then "for most people this probably won't be a big deal because adenoviruses are generally not thought of as really important human pathogens," she said.

Scientists back Brazil's move to ban import of Russian "Sputnik V" COVID vaccine
方舟子推特：“俄国疫苗声称有效性高达97.6%，向巴西申请上市，巴西药监不批准，因为他们拿俄国疫苗做了实验，发现所有批次都能复制。俄国疫苗使用的腺病毒载体Ad5本来应该是复制缺陷型，但他们忘了删除控制复制的E1，有完整复制功能，接种该疫苗相当于被腺病毒感染。俄国的生物医学就是这个水平，只会吹牛，别笑。”

从能力，到实施，完全不是一码事。
设计，和生产，更是两个完全不同的领域。
有些人，善于捕风捉影，夸夸其谈。更有人，笔下春秋、信口开河……

所有现在用的疫苗哪个经过了5年的3期临床测试? 这么大的危险都放任不谈，去扯一个媒体文章。
这种事情都没有证实，不过是一些利益集团的相互抹黑而已。
