Some Polish Professor estimates that 30 % of Poles will have Covid-19 most without symptoms by the end of October.By the end of year it will 50 % most without symptoms.Getting close to herd immunity ?Sorry I know some of you think this herd immunity is bullshit ,there are reinfections but very rare at the moment.I'm not sure about this herd immunity but in case when 90-100 % of people get this how can be there more infections ?

Mr Beutler did warn, however, of how the virus could become "elusive" to a vaccine through mutation.

He said: "Being an Rna virus, it has a weak 'proofreader' activity.

"Every time it replicates it makes mistakes and it’s unable to repair them as effectively as DNA cells.

"These errors are mutations and are an advantage for the virus because, if they are not lethal and are maintained, they make the virus itself continuously different and, consequently, elusive to the vaccine.

"It is necessary because other zoonoses like this current one will continually recur and we cannot count on therapies.
