You aren't really answering my question. Despite Youtube removing misinformation, anti-vaxxers have loudly and repeatedly 'made their point.' The marketplace of ideas is alive and well. It's hard to have an open and honest discussion with groups that falsify data, but many vaccine advocates have nonetheless engaged directly and publicly with anti-vaxxers.

What specifically is lacking in the pro-vaccine argument? I'm not asking about censorship, as it is seemingly a moot point. OPs point is that the argument needs to be made more convincingly and spoken louder. What does that look like in practice?
