Hi Pulisa not sure you'll remember me, but when I was a prolific poster we use to chat, hope you're well?
Yes, as stated, its a new virus. We don't know how long the antibodies stay in our systems. A normal cold/flu is 4 weeks. SARS is 2 years. I have a family member who is Matron on a Covid ward in Manchester. All nurses developed and tested positive for covid. All of them are now on the anti body trial yet only half have anti bodies. The logistics of working all this out is a minefield.
My personal opinion is the lockdown we had, was the second wave or the mutated version of covid. Covid has been here much earlier than the Gov want us to believe. Seasonal flu was very low last year/this year. I reckon any outbreaks now will be localised and not national.
I glad everyone is well. I understand your concerns my son also developed covid and it was a worrying time.
