Ah, ok. Forget the post-exposure treatment for rabies, then. While your example is irrelevant and meaningless with respect to Covid, you doggedly intend to cling to it, suggesting it's still got some validity.
Consider the pre-exposure rabies vaccination (which I have); it involves three shots, on days 0, 7, and 21 or 28. The truth is, a great many vaccines require multiple injections, and experience waning effects with time. Also true of most vaccinations; one may still be infected, even having been vaccinated. Certainly true of Covid. Of course, nearly all hospitalizations, and nearly add deaths, presently, occur with those who are not vaccinated. Presently increases in Hong Kong and South Korea show increased infections in both cases, but higher death rate in Hong Kong, where vaccinations for the elderly have a much lower incidence. The same demographic in South Korea shows far fewer deaths, and a correspondingly. higher level of vaccination.
If you don't remember anyone saying two years ago that a Covid vaccination was going to provide protection for only four months, it may be due to the fact that there wasn't a covid vaccine two years ago, and perhaps because the vaccine doesn't only provide protection for four months.
The vaccine's thus far fielded, being some of the most vetted and tested vaccines, with some of the highest sample yields of any ever fielded in vaccination history, have provided much better efficacy than most vaccines. When a vaccine has an initial effectiveness in the 91 percent rage (or higher), that's elevated quite a bit above what one can expect from many vaccines. When its effectiveness decreases to a point still above that which many vaccines provide, it's still doing well. Adding booster shots to bring the effectiveness back up isn't a bad thing, nor unwarranted, and has been a recommendation among the top health authorities on the planet.
I just came back from a flight physical; my AME is a pulmonary specialist who has been heavily involved in treating those hospitalized, including many in intensive care, these past two years. He's carried a high work load and he's seen a lot of people die. We had a talk about his thoughts on a fourth vaccination; he intends to get it, strongly recommended I do, too, and I will.
Others will choose not to be vaccinated at all. That's their choice. I don't really care.
So far as vaccinations that utilize boosters, there are many. Looking back at my shot record, I see multiple vaccines which have been received on a recurring basis. When the time interval comes around again, I'll get the vaccine again. That includes the rabies vaccine...I had the three shots to start, and if I need the vaccine after a bite (post-exposure), I'll get what's required. Few things in life last forever, whether it's the last meal, the roof, or a vaccine. Many vaccines utilize boosters, and initial shots in multiples. Not exactly a shock that a covid vaccine sees improved efficacy with additional shots over a given interval.
