Have you spoken to the consultants of the two extremely vulnerable people and sought their advice? I only ask because one of my children is clinically extremely vulnerable, definitely would stay on the shielded list even once they've taken the 90% of children off it that they are expecting to remove, has had injections to protect against RSV for her first 3 years of life (only child for 100 miles to have that treatment approved for a second year let alone a third), has been on antibiotics every day of her life, had to have medication to prevent the development of chicken pox etc. I'm just painting a picture that she's not a child who suffers from run of the mill asthma for example.
We spoke to her consultant last week and his advice was to send her to school, that in their very large hospital (one of the few children's ecmo centres for example, it is a specalist children's hospital) they've not had to admit any child, even those who are clinically extremely vulnerable, to ICU with covid complications. That we had to understand the perception of risk, and that the risk is on a macro scale, the NHS can't cope with all these people getting ill at once as it's a new disease and we have next to no herd immunity, rather than this being a micro scale risk ie she would get a lot sicker than with Covid19 than with a lot of other illnesses. Speaking to him was massively reassuring, he said at the moment we should live normally just with face masks and a lot of handwashing, go for days out, go to work and school, keep a close eye on cases in our area and if it starts going up to 20 or 30 a day then at that point change our behavior. Now what our consultant advised may be completely different for another illness, but he's kept her alive for 9 years, from the point where they thought she wouldn't live to see one, to when she would need a lung transplant to now. This is a new, difficult situation, the government has thrown some very mixed messages at us, but don't try to make this decision alone, ask the doctors involved in your families care what the actual risk is and go from there to decide what is best for your family.
