Hope you are correct. Certainly any 'organism' that kills its host is not very evolutionary effective. But so far the variants of Covid-19 (evolved!) have become more dangerous - affecting younger age groups and spreading more rapidly. Generally, very lethal organisms have low spread (e.g. Ebola) but the big problem would be a recombination of a killer virus genome with a fast spreading coronavirus genome.

The person who's message I partly quoted (but he's excused, because none of his brethren in Borneo were included in any trial for any vaccine)
A study by the CDC of adults above the age of 65 — the population most at risk — found that seniors who received partial vaccination (mRNA) were 64 percent less likely to be hospitalized, but fully vaccinated seniors were 94 percent less likely to be admitted to a hospital for Covid-19. Another study, published this month in Nature, found that the two doses of the Pfizer-BioNTech vaccine were 88 percent effective in preventing illness caused by the Delta variant that originated in India, but one dose was only 33 percent effective. The new Novavax vaccine is even better, according to trial data, with 90.4 percent efficacy even against variants. “The second shot is critical,” Dr. Paul Offit, a vaccine researcher at the Children’s Hospital of Philadelphia, told NBC News. “We know from the phase one studies that the second shot induces a level of virus-specific neutralizing antibodies that’s about tenfold greater than that after the first dose.” https://www.rollingstone.com/politics/politics-news/covid-deaths-unvaccinated-1189072/
