There is no conclusive evidence that mRNA vaccines prevent people from getting the virus. That means you can possibly get infected even after vaccination. There is no conclusive evidence that mRNA vaccines prevent the spread of the virus to others.
That means herd immunity from a mRNA vaccine is a myth. Do you accept that fact or are you in denial of it?
Why are they called gene vaccines?

You're goalpost moving changing "no evidence" to "no conclusive evidence".
The evidence is sufficiently supported by numerous studies to conclude that the present vaccines are effective (no, not 100% effective - no vaccine is that) in preventing COVID-19. And infection by the virus at all:
"A new CDC study provides strong evidence that mRNA COVID-19 vaccines are highly effective in preventing SARS-CoV-2 infections in real-world conditions among health care personnel, first responders, and other essential workers. These groups are more likely than the general population to be exposed to the virus because of their occupations.
The study looked at the effectiveness of Pfizer-BioNTech and Moderna mRNA vaccines in preventing SARS-CoV-2 infections among 3,950 study participants in six states over a 13-week period from December 14, 2020 to March 13, 2021.
Results showed that following the second dose of vaccine (the recommended number of doses), risk of infection was reduced by 90 percent two or more weeks after vaccination.
Following a single dose of either vaccine, the participants’ risk of infection with SARS-CoV-2 was reduced by 80 percent two or more weeks after vaccination."
" this study evaluated vaccine effectiveness against infection,
including infections that did not result in symptoms."

As far as transmission, while scientists, unlike cranks on globalresearch.org, are reluctant to make claims before full experimental results are in, preliminary studies do support the idea that the present vaccines prevent transmission from the vaccinated (who are much less likely to be infected see above) to the non-vaccinated:
" “
Vaccines have always decreased transmission. What they should be saying is that the clinical trials were not designed to test for asymptomatic infection, but there is every biological reason in the world to believe that they will reduce asymptomatic transmission.”
There is already evidence to support this, she says. First, when the vaccines were studied in macaque monkeys (during preclinical testing), they did eliminate asymptomatic infection — researchers swabbed the vaccinated macaques’ noses and found little or no virus. Second, the types of antibodies that are stimulated by most systemic vaccines (IgG and IgA) do tend to block viral infection in the nose (and no viral load in the nose most likely translates to no transmission). Finally, when monoclonal antibodies are given to COVID-19 patients, those antibodies reduce the viral load throughout the respiratory tract, including the nose.
The most convincing evidence, though, is just starting to emerge among real-world data. In Israel, where more than 90% of those age 60 and over have been vaccinated, “cases have plummeted in this population,” Gandhi notes. “Not just hospitalizations, which we expected, but cases [asymptomatic infection] as well.” Moreover, data from vaccinated health care workers recently published in the Lancet and preprint servers show reduced rates of asymptomatic infection and low viral loads in the nose when swabbing after vaccination.
“I think that in a few months, we are going to be able to say with certainty that these vaccines not only protect you, they also protect those around you,” Ranney says."
