From CDC: Today, CDC is reporting 971 cases of measles in the United States thus far in 2019. This is the greatest number of cases reported in the U.S. since 1994, when 963 cases were reported for the entire year.
A 2018 release from George Washington University:
Social media bots and Russian trolls promoted discord and spread false information about vaccines on Twitter, according to new research led by the George Washington University. Using tactics similar to those at work during the 2016 United States presidential election, these Twitter accounts entered into vaccine debates months before election season was underway. The study, "Weaponized Health Communication: Twitter Bots and Russian Trolls Amplify the Vaccine Debate" was published today in the American Journal of Public Health.
The team, which also includes researchers from the University of Maryland and Johns Hopkins University, examined thousands of tweets sent between July 2014 and September 2017. It discovered several accounts, now known to belong to the same Russian trolls who interfered in the U.S. election, as well as marketing and malware bots, tweeted about vaccines and skewed online health communications.
"The vast majority of Americans believe vaccines are safe and effective, but looking at Twitter gives the impression that there is a lot of debate. It turns out that many anti-vaccine tweets come from accounts whose provenance is unclear. These might be bots, human users or 'cyborgs' -- hacked accounts that are sometimes taken over by bots. Although it's impossible to know exactly how many tweets were generated by bots and trolls, our findings suggest that a significant portion of the online discourse about vaccines may be generated by malicious actors with a range of hidden agendas," David Broniatowski, an assistant professor in GW's School of Engineering and Applied Science, said.
Ben Popken and Maggie Fox reported last year at NBC:Now the Russians are pushing a new myth.
An NBC News analysis of over a million tweets sent by identified Russian trolls published by the data journalism website FiveThirtyEight and Clemson University researchers found over 500 examples of tweets that mention vaccines, often spreading misinformation and discredited theories.
“The Vaccine Hoax is Over — Secret Documents Reveal Shocking Truth,” wrote Russian troll _NICKLUNA_ in February 2017. “Autism Rates in California Have Skyrocketed Following Mandatory Vaccination Bill,” tweeted Amelie Baldwin, a prolific Russian troll, in December of 2016.

The cellphones known as 5G, or fifth generation, represent the vanguard of a wireless era rich in interconnected cars, factories and cities. Whichever nation dominates the new technology will gain a competitive edge for much of this century, according to many analysts. But a television network a few blocks from the White House has been stirring concerns about a hidden flaw.
“Just a small one,” a TV reporter told her viewers recently. “It might kill you.”
The Russian network RT America aired the segment, titled “A Dangerous ‘Experiment on Humanity,’” in covering what its guest experts call 5G’s dire health threats. U.S. intelligence agencies identified the network as a principal meddler in the 2016 presidential election. Now, it is linking 5G signals to brain cancer, infertility, autism, heart tumors and Alzheimer’s disease — claims that lack scientific support.
