Could too many Covid vaccines be bad? Yahoo News
Australia has just expanded access to a second COVID booster to everyone 30 years and over, while recommending it only for people 50 and over. That means it’s up to people aged 30-49 years to decide whether they would like a second booster, but they will not be actively encouraged.
The promise of COVID vaccines as a means to completely ending the pandemic was short-lived.
Vaccines are not as protective against variants such as Omicron and also wane in protection, which is why we have seen continued waves of infection even in highly vaccinated countries.
This is just my opinion.
