Am I the only one wondering why they are talking of a 12-18 MONTH development period for a COVID-19 vaccine but we have been waiting now for 40 YEARS for an HIV/AIDS vaccine??
Now it is true that HIV/AIDS is a tougher target -- a) it is caused by a retrovirus rather than a coronavirus, b) HIV/AIDS is known to mutate frequently presumably making it a far harder target to attack.
HOWEVER, 40 YEARS difference? And still no vaccine?
