But as the SARS-CoV-2 virus mutated its genetic code and slightly remoulded its spike protein, it was better able to fly under our immune system's radar.
"The beauty of the RNA [vaccine] platform is that you can very easily change the DNA template that you use to make the RNA. Large companies such as Pfizer and Moderna can feasibly make an Omicron-specific vaccine for testing within a week or so, says Colin Pouton, a pharmaceutical biologist at Monash University.
"When you give a vaccine, you prime the immune response to produce antibodies … then you boost it by giving a second dose or a third dose," Professor Pouton says.
So, why?
Current vaccines work pretty well against severe illness and death with Omicron. Achieving sterilizing immunity seems impossible with SARS-CoV-2. Mixed boosters plus early antivirals for at infected at-risk individuals are our best strategy for now
Well the current mRNA ones clearly don’t work so…
The media love triggering the antivaxxers. They bite everytime
No science is 100% exact; no medication is 100% effective; and the Covid-virus is a particularity difficult bugger. But getting your vaccines, wearing suitable masks, eating healthy, etc. will give you an enormous advantage over dimwits.
You mean why wasn’t there?
And they are experimental with no long term studies to support their safety. Notice all the people around the world dying from heart attacks ?
