Since you refuse to provide actual sources, I'll provide sources with evidence against your claims.
More mutations isnt an issue, its what the environmental selection pressure does with them that counts. A billion strains selected for lower virulence isnt an issue - two strains selected for immune evasion is. Mutation is the raw material for evolution - the direction of evolution is dictated mainly by the selection pressure. Survival of the fittest.
While your statement is true for evolution
in general,
literature on how virus variants occur largely contradicts this. The mutation rate
is the most important factor for developing a mutation that increases the
spread of the virus. Like what happened with Delta.
Virus mutations create genetic diversity, which is subject to the opposing actions of selection and random genetic drift, both of which are directly affected by the size of the virus population. When the population size is large, selection will be predominant and random drift less common. This means that deleterious alleles will be efficiently removed from the population, while adaptive alleles will have an opportunity to take over the population. However, when the population size is small, random effects may obscure the effects of selection. Under these conditions, slightly deleterious alleles may rise to an unexpectedly high frequency in the population, and adaptive alleles may be lost by chance.
No matter how right the environment for selection pressure is, evolution won't happen at any significant rate if the number of viruses in total remains small. The vaccines are extremely effective at keeping these numbers small for
most infections. Delta is seen at similar viral loads as infected individuals in
some cases, but this in of itself is not evidence for virus-driven evolution.
When it comes to increasing the deadliness of coronaviruses, this too has been
studied for SARS and MERS with the goal of understanding how ADE would appear in Covid.
From previous research on ADE in other coronaviruses, in particular SARS-CoV and MERS-CoV, it appears that the existence of ADE will elicit more severe body injury, while actually reducing the viral load at the same time.
In previous cases of ADE, such as with the Respiratory Syncitial Virus (RSV) vaccine, this effect
was seen in both
cell cultures and
primates.
These effects
have not yet been observedfor COVID-19
. Not in animal trials. Not in human trials. Not in the general public. In fact, the symptoms have almost entirely been
less severe.
It's still
possible that ADE could occur, just like it's possible I could get in a car wreck tomorrow, but it's not likely. There was some behavior of the coronavirus early on in China that people thought could be attributed to early ADE, but this behavior could not be replicated with
convalescent plasma therapy nor
inactivated vaccine candidates (which are
known for producing ADE).
In fact, there aren't many cases of ADE documented with Coronaviruses in
general. With SARS, there was
one vaccine candidate out of four in one
study, but
two other studies failed to observe any ADE.
(Are there vaccines for the nucleocapsid? I'm still new to all this.)
Nevertheless, researchers chose to target the spike protein specifically
because it was much
less likely to lead to ADE than viruses targeting the
nucleocapsid, which did show some signs of possible ADE, and also nucleocapsid-targeting antibodies are less effective at combating variants compared to the spike antibodies.
There is one researcher who
hypothesizes that ADE may still be a sizable risk for COVID-19, even for spike-targeting antigens. It's not a concern that is outright dismissed. However, there has not yet been any empirical data showing signs of vaccine-driven ADE to date.
No this is variation within the antibodies within one small bit - the RBD. It’s not able to give antibodies to the nucleocapsid or any other viral components. The epidemiology is tentatively showing this too - those with prior confirmed infection seem to be falling ill at lower rates to those vaccinated.
Recent research (preprint) suggests the
opposite for mRNA vaccines
, and
not for the
CoronaVac, which is China's vaccine that uses the whole virus
.
These results indicate that mRNA vaccination rapidly induces a much stronger and broader Ab response than SARS-CoV-2 infection.
A LOT of what they're saying lines up basic biology education from like high school and such. Even the stuff about evolution and selection pressure on viruses.
It makes sense following basic biology for high school, yes. But there is a reason that Virologists aren't given employment with a simple high school diploma. Reality can often be a
lot more complex than high school biology education allows time to learn.
There are many theories that
make sense, but are also wrong or unsupported by observational data.
