Given that Covid 19 has mutated rapidly and repeatedly and that these vaccines reached the market in record time, the previous fastest took 4.5 years, I'm not surprised that we're advised to acquire boosters.

There are many vaccines that require 3 doses followed by boosters such as Hep B, Rabies and Jab B Encephalitus. The booster schedule for covid is more frequent but not that unusual.

Also you don't need 5 doses to be considered fully vaccinated. The entry requirements for Cambodia consider a person to be fully vaxxed after 2 doses.

Yes, Rabies.

5 shots in a month (day 1, 3, 7, 14, 28), one year efficacy. After that booster if required.

That's once you've been exposed. The preventative protocol is 2 shots on day 0 and 7.

And, Rabies vaccine stops you getting rabies, Covid vaccine does not prevent infection.

Certain people with a higher risk for rabies exposures, such as those who work with potentially infected animals, are recommended to receive vaccine to help prevent rabies if an exposure happens.

If you have received rabies vaccination in the past, you typically need only 2 doses of rabies vaccine after an exposure.

Secondly, what is has mutated into, Omicron and all it's new variants, is far milder and had it started life that way we never would have had to go through lock downs etc.

Finally, it is a contradiction that say a person is fully vaccinated if they keep telling people their booster is due. They have millions of doses running out of date and they need arms to stick them into.
