I respectfully disagree.
By the time anyone in government took Covid seriously it was March 2020, and Covid was already everywhere at that point.
Studies show that even strict social distancing and mask use at best reduces, but does not eliminate, spread. Doesn't get it down low enough to eliminate, certainly.
The best bet for getting rid of it was the vaccines, but they are leaky, and it looks like people are going to need boosters to keep the immune response up.
Even New Zealand and Australia, which are the most successful western nations re keeping covid out, are seeing more cases now. Unless you commit to autarky and close your borders (only really possible for island nations), Covid is here to stay.
If public health measures worked to get rid of covid, and if it was a matter of moral blame that can attach to some group, you would expect someone in the world to have eliminated Covid, but the truth of the matters is once it was allowed to spread in the community beyond a couple of cases, Covid was here to stay. We don't actually have tools that can eliminate it.
