A desperately-needed COVID-19 vaccine may never come to light, according to the Australian scientist heading up the global search.

Health officials urgently need a ‘plan B’ to end the global pandemic, Jane Halton, the country’s foremost epidemic health expert warned.
Scientists all over the world are scrambling to develop a vaccine, with hopes it would be available early next year – a timeline Ms. Halton called ‘unbelievable’.
She warned against creating ‘unrealistic expectations’, explaining that there has never been a successful vaccine against other coronaviruses.

Despite a global HIV death toll of 32 million people over 40 years, it also has no vaccine. This includes 770,000 deaths in 2008 alone.
