But you ignore the fact that boosters aren't recommended for the majority of the population.
The Therapeutic Goods Administration (TGA) has approved a booster dose of the Pfizer COVID-19 vaccine for individuals 18 years and older. There is no health warning in the annoucnment recommending the majority do not get a booster. ATAGI are poised to update their advice re boosters for the program to start next week.
Why don't you post the actual FDA booster eligibility criteria for which EUA has been granted? Because they are not what you or your anecdotes about booster shots in the US say they are.
I have done this previously, my post is entirely consistent with the formal advice. Perhaps you are unaware that the FDA have updated their advice over the last week:
Coronavirus (COVID-19) Update: FDA Takes Additional Actions on the Use of a Booster Dose for COVID-19 Vaccines
The FDA took additional actions regarding booster doses of COVID-19 vaccines, including authorizing heterologous booster doses in eligible individuals.
- The use of a single booster dose of the Moderna COVID-19 Vaccine that may be administered at least 6 months after completion of the primary series to individuals:
- 65 years of age and older
- 18 through 64 years of age at high risk of severe COVID-19
- 18 through 64 years of age with frequent institutional or occupational exposure to SARS-CoV-2
- The use of a single booster dose of the Janssen (Johnson and Johnson) COVID-19 Vaccine may be administered at least 2 months after completion of the single-dose primary regimen to individuals 18 years of age and older.
- The use of each of the available COVID-19 vaccines as a heterologous (or “mix and match”) booster dose in eligible individuals following completion of primary vaccination with a different available COVID-19 vaccine.
- To clarify that a single booster dose of the Pfizer-BioNTech COVID-19 Vaccine may be administered at least 6 months after completion of the primary series to individuals 18 through 64 years of age with frequent institutional or occupational exposure to SARS-CoV-2.
And the bolded text is why it is very easy to qualify for a Moderna or Pfizer booster if you have a job where you are interacting with large numbers of the general public. Its not just medical and emmergency services workers. Transportation workers, teachers, cashiers are all using that clause and all having no issues getting boosters.
