But Professor Ian Frazer, who co-invented the revolutionary vaccine for cervical cancer, also said that it was possible that Covid-19 would naturally decrease, thereby becoming less effective on its own.
The Australian told news.com.au that trying to get the coronavirus vaccine was like trying to get the cold vaccine – difficult to impossible.
He added, “It’s tricky, vaccines for upper respiratory disease, because the virus lands outside of you. “
Professor Frazer of the University of Queensland said that 100 teams around the world are testing vaccines, but noted that there is no blueprint for attacking Covid-19.
Vaccinating against the flu was easier, he said.
“The coronavirus does not penetrate you, it stays on the surface of the cells of your lungs,” he added. “All of these flu viruses get into you, so the body can fight and make T cells.”
“This virus does not kill cells, it makes them sick. At this time, we do not know how to make a coronavirus vaccine work. This is why there are 100 vaccines under test using every conceivable approach.
“We don’t know if any of them will work. “
On a more positive note, Professor Frazer pointed out that a vaccine was never developed for SARS following an epidemic in China in 2003, but that it burned on its own.
The virus became less effective when passed from host to host, said Professor Frazer – something that could also happen with Covid-19.
He added, “It could be the same with this virus. It’s not very effective in making us sick. It may become less effective. ”
