Bydd y cyngor newydd yn golygu na fydd yn ofynnol mwyach i tua 2,700 o blant a phobl ifanc warchod eu hunain os bydd angen ailgyflwyno'r mesurau gwarchod, er bod hynny’n annhebygol. Bydd pob plentyn a pherson ifanc y mae'r newid hwn yn effeithio arnynt yn derbyn llythyr gan y Prif Swyddog Meddygol yn esbonio nad ydynt bellach yn cael eu hystyried yn eithriadol o agored i niwed yn glinigol o effeithiau haint Covid-19, ond y dylent barhau i gymryd camau i leihau eu risg o ddal y feirws.
The new advice will mean approximately 2,700 children and young people will no longer be required to shield in the unlikely event that shielding was to be reintroduced.  All children and young people affected by this change will receive a letter from the Chief Medical Officer explaining whilst they are no longer considered clinically extremely vulnerable to the effects of infection with COVID-19,  they should continue to take action to minimise their risk of contracting the virus.
