I'll give it a month before they start clinical trials using leeches.
You can disagree, but i think you didn't read the article.
Here is an excerpt:
Vaccines generally raise immune responses specific to a targeted pathogen, such as antibodies that bind and neutralize one type of virus but not others. But BCG may also increase the ability of the immune system to fight off pathogens other than the TB bacterium, according to clinical and observational studies published over several decades by Danish researchers Peter Aaby and Christine Stabell Benn, who live and work in Guinea-Bissau. They concluded the vaccine prevents about 30% of infections with any known pathogen, including viruses, in the first year after it’s given. The studies published in this field have been criticized for their methodology, however; a 2014 review ordered by the World Health Organization concluded that BCG appeared to lower overall mortality in children, but rated confidence in the findings as “very low.” A 2016 review was a bit more positive about BCG’s potential benefits but said randomized trials were needed.
Or putting it into English the BCG vaccine might provide a bit of enhanced protection against other infectious diseases or it might not.
A review oranised by experts thinks it's improbable but to be sure you need more experiments.
