Do you think that anti-vaxxers might have an advantage here?
No, vaccines work by provoking the immune system to respond. Anti-vaxxers are probably therefore @ a severe disadvantage to someone who's had the normal course of vaccinations - if their (the anti-vaxxers') immune response has only been triggered by actual diseases that they've encountered.
There's a lot of material to cover in order to make sense of the topics involved in Wuhan CV - you might want to look @ Wuhan CV, coronaviruses in general, vaccines - just to get a feel for the issues.

This ^^^ makes no sense. Immunity is very specific to the virus, that is partly why a new flu vax is needed every year - the virus mutates and the old vaccine no longer works, or your immunity simply diminishes over time. Flu is not even a corona virus so I am not sure why you think a flu vaccine would provide some sort of immunity to WCV. People are not normally vaccinated against MERS and SARS which are the only two deadly corona viruses I am aware of.

Immunity is very specific - Yes.
Flu is not even a corona virus - Yes.
I was making an analogy: vaccines work by provoking an immune response to a weakened version of the target virus. Someone who's had a full course of the normal vaccinations will have had their immune system alerted & appropriate antibodies produced each time.
An anti-vaxxer presumably would never have had vaccinations, & so their immune system has only responded to actual infections - which vary by location, season, etc.
& therefore, the immune response of someone who's had a full course of vaccinations is likely to be stronger than that of an anti-vaxxer, someone who's never had any vaccinations @ all.
It's this practice effect that I was referring to. Someone (in Canada?) has already tried the SARS & MERS vaccines on someone infected with Wuhan CV - it didn't work.
In contrast, 5 cases of the corona virus had been confirnpmef in the US.
What an odd apples to oranges comparison. The flu season started last October. In contrast, the first reported coronavirus infection in the U.S. was last week.
I'm guessing that every country that worked on the SARS virus is collaborating to develop a vaccine for the new strain of coronavirus.
"As Canadian public health agencies prepare to deal with a new viral illness, a specialized lab in Saskatoon is using its research on different strains of the coronavirus to help develop a vaccine.
The University of Saskatchewan's Vaccine and Infectious Disease Organization-International Vaccine Centre, also known as VIDO-InterVac, has received permission from the Public Health Agency of Canada to focus on the threat.
...
The Saskatchewan lab was developed in the wake of the Severe Acute Respiratory Syndrome, or SARS, outbreak in 2003 to ensure that Canada could be prepared for emerging disease and illness, he said.
Researchers there have spent a significant amount of time focusing on pathogens like coronaviruses. Gerdts said they've successfully developed a vaccine for coronavirus strains in cattle and pigs.
...
Colleagues in China have made the outbreak-specific coronavirus genome sequence available to researchers around the world, Gerdts said. His lab is now using it to hopefully find a way to help.
The lab also has clearance to handle samples of the pathogen and is attempting to get samples from China or the U.S. If that's not possible, it will order synthetic gene fragments.
The goal is to have the first vaccine candidates ready for testing in animals within six to eight weeks, Gerdts said. But human trials are at least a year away.

Theresa Tam, Canada's chief public health officer, said Canadian research is part of a global effort and will be shared with the World Health Organization."
As of Jan. 28, there are 4,474 confirmed cases and 107 deaths related to the 2019-nCoV coronavirus, a respiratory infection originating in central China.
Six updates:
1. The CDC has confirmed five U.S. coronavirus cases in Arizona, California (2), Illinois and Washington as of Jan. 27. Thirty-two tests have come back negative for coronavirus, while 73 are pending. Investigations of potential cases are being conducted in 26 states. 2. 107 total deaths have been reported, all in China, as of 9 a.m., Jan. 28. Sixty-three patients sickened by coronavirus have recovered.
3. U.S. citizens are urged to avoid all nonessential travel to China. The U.S. State Department issued a level 4 travel warning for the Hubei province Jan. 27, and the CDC issued a level 3 travel warning, its highest alert level.
4. Three patients with coronavirus never visited China, Paul Hunter, MD, a professor of medicine at the University of East Anglia's Norwich Medical School in the U.K., told The Guardian. This backs the theory that the disease is spread via human transmission.
5. Everyone is now legally required to wear face masks in South China, according to The Guardian.
6. HHS Secretary Alex Azar held a press conference Jan. 28 advising providers to ask patients exhibiting respiratory symptoms if they traveled to China.
CDC Director Robert Redfield, MD, also spoke, identifying 18 international locations with confirmed coronavirus cases. He said the CDC will now screen travelers at 20 U.S. airports, but added that the immediate risk in the U.S. is low.
