Singapore has fully vaccinated 82% of its population with the Pfizer and Moderna vaccines. It has very strict control over who enters the country. It also has very rigid government authority and a population that follows rules. The Delta variant hit them in early September. They now have their highest daily new case rates since COVID started. So the answer is absolutely no. We will never be able to vaccinate our way out of COVID. It’s a coronavirus. It mutates too quickly to ever be controlled by a vaccine. This was known before COVID was ever a thing and it hasn’t changed.
You are right, there was something about being unable to produce a vaccine against this virus way back in 2020. At this point it looks like they should pull the plug on the whole project.
Another reason they can’t vaccinate their way out of Covid is because it has also escaped into numerous other mammal species where it can also mutate and then jump back to humans, rinse, repeat with the stupid masks and lockdowns.
It’s time to concentrate on therapies and treatments, not vaccines because this genie is not going back into the bottle.
I personally believe this little bat virus’s ability to infect entire zoo’s worth of mammal species is proof that it is a lab gain of function creation.
